The Reproductive System.
The Reprodructive system or genital system is a system of sex organs within an organism which work together for the purpose of sexual reproductive. A human has 46 chromosomes in each cell except sex cells. A person recieve 23 chromosomes from the mother and 23 chromosomes from the father . The mother has X chromosome and the father has Y chromosome . XY chromosomes are also found in other mammals , some insects and some plants . Now let’s talk about the male reproductive system. The male reproductive system consists two major parts which are testes and penis . The spermatozoa (sperm) includes four main parts of the male body which are the penis , uretha , vas defences , and cowper’s gland . Testes is where the sperm

Vas deferens transport the sperm to the penis . Cowper’s gland has two small glands that secrete a mucous to the male uretha . All boys are born with foreskin which is a folded skin that covers the penis . The doctor have to cut the foreskin off . When a new born baby is born that’s when they usually cut it . The male have 5 secondary characteristics which are growth , more muscular , deeper voice and body hair that’s dealing with puberty . Most males stop growing at 18 or sometimes 21 . Also hair starts to come in during puberty . The female reproductive system includes the clitoris , labia minare , and Blartholin’s glands . The clitoris is small sensitrive and erectile part of the female vulva . The inner and outer folds the uvlua . The Bartholin’s glands is the lower part of the vagina . The vagina meets to the outside at the vulva , which includes the labia , clitoris , and uterus . Also the vagina is a fibro - muscular tublar tract leading from the urterus . The ovaries are small and the place inside the female body the place inside the female body . The speed of ovulation is periodic and impacts directly to the length of mestrual cycle . The breast starts to come in during
The abdomen of the male contains only five segments while that of the female contains seven.
The testes produce sperm and sex hormones, testosterone. Surrounding each testis is a coiled tube called the epididymis, which collects and stores sperm, very much similar to that of a human. Before ejaculation a seminal fluid is added by the seminal vesicles, to prevent the sperm from drying out.

The main difference between male and female primates is that female primates are the ones who conceive an offspring. If primate males were the ones to conceive, then the roles would be completely different. There are two different reproduction strategies the male and female follow in the primate world. The male strategy would be to always be ready and wanting to mate, so he can maximize reproductive success. The female reproductive strategy would be to make males compete for her and also to select a quality male (Male with territory and/or ability to protect her and her offspring). Another female reproductive strategy that will benefit her is, sneaky copulation because it creates a confused paternity so, if the transient male takes over the group the offspring will not be killed. The male parental investment is fairly low; mostly all the male does is just give the sperm to the female and take off onto seeking another mate. As for the female parental investment, it’s extremely high; because she must grow the offspring in her body, give birth, nurse and raise the young. The factors of limiting male’s reproductive success would be female access and competition with another male. As for the factors of limiting female’s reproductive success would be food resources, and a predator free space. The male strategies maximize reproductive success because, with males spending less time on parental investment they can seek more mating opportunities; for a chance the female will take care of the offspring so that his genes can be passed on. Another way males maximize their reproductive success would be to eliminate all unfertile females from their mating because there is no way that the male genes could be passed on. Females use their strategy ...

The Egg and Sperm by Emily Martin and The Environmental Movement by Meredith Burke both criticize the role of culture in understanding nature. Martin does this by analyzing the gender stereotypes that stem from cultural beliefs hidden within the scientific language of biology. (Martin, 486). For example, Martin criticizes how the monthly menstrual cycle is described as a waste as an egg is “lost” and wasted every month because the ultimate goal of the egg is to be fertilized all to make babies (Martin, 486). She also mentions how textbooks and scientific readings depict cultural stereotypes in different ways like making the egg useless and helpless until the sperm fertilizes it.
...per’s glands mix with sperm to form semen. Each testis made up of small, coiled tubes called the somniferous tubules. From there, the immature sperm pass through the epididymis, which is a storage area on the upper rear part of each testis. The vas deferens is a tube that leads upward from each testis into the lower part of the abdomen. The two vas deferens empty into the urethra. The female reproductive system is somewhat like that of the frogs. In the female reproductive system the ovaries produce the female sex hormones estrogen and progesterone. In the ovaries eggs mature in the follicles. Fertilization may occur when the follicle breaks and the egg is released into the oviduct.
After the gross anatomy experiences, I have a more realistic view of the male and female reproductive systems. I was about to see how the fallopian tube, uterus, fundus, penis, bladder, prostate, vas deferens, and other organs. The two systems work together in order to produce babies. After the lecture in Nursing Care Childbearing lecture, I have a general idea of how the female and male bodies work and also the progress of making
A male makes one thousand new sperm per second, that is two trillion over a lifetime and they all are one of a kind, very unique. A woman has all her eggs from birth. The process starts out as meiosis, this is where 30,000 genes are then there are forty six chromosomes. Twenty three comes from your mother and twenty three come from your father, they only come together in meiosis in pairs, but they are not the same. Chromosomes make an exact copy of themselves then they condense making an X shape, chromosomes get a partner then embrace. The chromosomes cling close together in big chunks, the cell then divides pulling the pair apart with twenty three chromosomes. The cell alone is incomplete, but holds many promises. Every cell holds di...
Inside the cells that produce sperm and eggs, chromosomes become paired. While they are pressed together, the chromosomes may break, and each may swap a portion of its genetic material for the matching portion from its mate. This form of recombination is called crossing-over. When the chromosomes glue themselves back together and separate, each has picked up new genetic material from the other. The constellation of physical characteristics it determines is now different than before crossing-over.
In order to grasp the concept of social construction of gender, it is essential to understand the difference between sex and gender. Biologically, there are only two reproductive genital organs that are determinants of sex: the vagina and the penis. Sex is established solely through biological structures; in other words, genitalia are the basis of sex. Once a sex category is determined, gender, a human categorization socially attached to sex, is assigned based on anatomy. Gender typically references social or cultural differen...
The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner. When sperm is produces the ...
The female reproductive systems is made of 9 parts. The sex cell for the female reproductive system is called the egg or ovum. The egg spends it’s dormant life in the ovaries until it is released. The egg has 23 chromosomes within it. The ovaries have two goals: to create and house eggs and the release the female sex hormones, estrogen and progesterone. The fallopian tubes are what the egg travels through to reach the uterus. Fallopian tubes contain tiny hair-like structures called cilia; the cilia allows for mobility of the egg. The fallopian tube is roughly the size of 2 hairs, and is the site of where ectopic pregnancies happen. The process of the egg getting released from the ovaries through the fallopian tubes is called ovulation. Ovulation happens on the 14th day of the menstruation cycle The uterus is where the egg goes to after it travels through the fallopian tubes. The developing baby is held and nourished in the uterus. When the uterus is empty, it’s roughly the size of a fist but expands one an embryo starts to develop. The endometrium is the lining of the uterine wall. It’s used to protect the fetus. When the egg isn’t fertilized, menstruation ha...
The Female Reproductive System consists of the Female sex cells, Vagina, Labia, Clitoris, Urethra, Hymen, Uterus, Cervix, Fallopian tubes, Ovaries, Estrogen, and Progesterone. The female sex cells, otherwise known as ovum, which are created by the ovaries, combines with male sperm, give a fertilized egg a home, and create an embryo. The vagina, also known as the birth canal, joins to the bottom of the uterus (cervix) and it holds male gametes during sex and provides leave for a baby’s birth. It is located towards the bottom of the pelvis. The Labia can be split up into 2 parts, the Labia Majora and Labia Minora. The Labia Majora, also known as the outer lips, is an external sex organ connecting to the thighs which are fleshy and grow pubic hair. The Labia Minora, otherwise known as the inner lips protect the vagina and the urethra, and are located under the Labia Majora. The Labia Minora can be differently textured, and can swell when due to arousal. The Clitoris is a tissue between the Labia Minora, which fills with blood and becomes erect during arousal. The Clitoris looks like it was built for arousal and pleasure, with the clitoris being sensitive by having a prepuce (shaft) and two cruca, which have networks of sensitive nerves. The urethra is a tube that removes fluid from the bladder and takes urine from the body. The Hymen is a thin tissue, which stretches across the opening to the vagina (Vanessa Cullins, 2013). The Uterus, also known as the womb, is composed of two parts, the cervix and the corpus. The cervix located at the top of the vagina, lets sperm enter and blood due to menstruation out. The corpus expands to hold a developing baby and has the shape of a pear. The Fallopian Tubes ...
...culatory system. Pituitary gland is a growth hormone that helps in mertabolism and develops reproductive organs. The thyroid controls metabolsim on the rate that the body breaks down food. Adrenal gland secretes many hormones including adrenaline which prepares the body to react in a stressful situation. The pancreas produces digestive enzymes and insulin. Ovaries produce ova and estrogen. Testes produce sperm cells and testosterone. To stay healthy you should get a regular medical check-up, eat a well-balanced diet, sleep at least 8 hours, and decrease stress in your life. Some problems are growth disorders, diabetes, and obesity. Puberty begins at different times for girls then boys. Girls start around ages 9-13 and boys are ages 10-15.
