The male reproductive organ system is made up of the penis, urethra, prostate, bladder, scrotum, and testes. The testes are the egg shaped organ in the male’s scrotum. The male reproductive system purpose is to do three things, produce, maintain, and transport sperm, discharge sperm into the female reproductive system, and produce and secrete sex hormones to maintain the reproductive system (N.A, 2014, Para. 1). The testes are responsible for producing testosterone which is the primary sex hormone, and sperm. Sperm is the male reproductive cell that fertilizes the female egg after ejaculation.
The scrotum is the pouch of skin under the penis that hold the testes. The scrotum is a temperature control system for the testes. The scrotum is supposed to be a few degrees cooler than the body. It works by contracting the muscle to bring the testes closer to the body in order to make them warmer. If the scrotum becomes too warm, the muscle releases and allows the testes to descend to cool the temperature.
The prostate is a gland that constricts the urethra in two places. When the male uses the bathroom to urinate, the prostate constricts the urethra by the spermatic cord. By doing this, the bladder is able to eliminate the urine from the body. During sexual intercourse the prostate constricts the urethra from the bladder allowing the sperm to travel through the ur...

...e different drugs consist of NRTI’s, PI’s, NNRTI’s and others. NRTI stands for nucleoside reverse Transcriptase Inhibitors, and these offer faulty versions of the necessary building blocks for the virus to replicate (Verville, 2013, para. 4). NNTI stands for Non-Nucleoside reverse transcription inhibitors which disable the protein that the virus needs to replicate. Entry/Fusion Inhibitors work with the CD4 cells and block the ability of the virus to enter the cell. Last but not least there is an Integrase Inhibitor that goes to work on cells that have already been infected by the virus. When HIV infects a cell, it changes the genetic makeup of the cell with the help of the Integrase protein. The medication works by blocking the ability of the virus to enter the cell through the Integrase protein, stopping the replication of infected cells (Verville, 2013, para. 3).

- The human body is made up of 12 different systems. Each system has a separate function while some do work together. One system is called skeletal system which is to serve as a support the body, mineral storage, energy storage (fat), blood cell production, movement (leverage), and protect the internal organs. (Martini, 112). With the help of the muscular system, it keeps us moving and makes us to do tasks that we don’t think about like swinging the arms while running. The average adult skeleton has 206 bones that are joined together by ligaments (bone to bone) and tendons (muscles to bone) to make a protective framework for the tissues and muscles....

- The Circulatory System The circulatory system works as the body’s transportation network, tirelessly sending nourishment and protection to all vital parts. According to Merriam-Webster, the circulatory system is “the system of blood, blood vessels, lymphatics, and heart concerned with the circulation of the blood and lymph.” While many may already be familiar with the circulatory systems’ role in the transport of oxygen, it does much more. In reality, the circulatory system is built of two subsystems: the lymphatic system and the cardiovascular system.... [tags: Blood, Heart, Immune system, Circulatory system]

- The human digestive system is a bodily process made up of many systems, organs and substances that break down food both physically and chemically for use by the body. But what exactly is human digestion and what happens to food as it moves through the digestive system. “…[digestion] is a group of organs working together to convert food into energy and basic nutrients to feed the entire body” (Tim Taylor). There are three major bodily mechanisms that contribute to the process of digestion. The first mechanism is the breakdown of food, the second mechanism is the process of extracting nutrients from food, and the third mechanism is excretion, or the body’s natural waste system....

- ... The nose filters and provides a passageway for air on its way to the lungs. The nose leads to the pharynx, which is also known as the throat. It is a passageway for both air and food. It is divided into two sections, the trachea and the esophagus. The trachea diverts air from the nose to the lungs. It has a flap called the epiglottis to cover the opening of the trachea so food and liquid do not get into the lungs. Below the pharynx and on top of the trachea is the larynx, also known as the voicebox.... [tags: organs, tissues, lungs]

- Every organism (vertebrate or invertebrate) needs a system to function. One of these systems is Nervous System which helps in transporting the messages from brain to different parts of body. It is made up of central nervous system and peripheral nervous system. In nervous system, neurons which are considered as major player receive and transport the electric and chemical signals and are also known as communication center. Neurons are again classifies into three types; sensory neurons which transport the material carried from external stimuli, interneurons which associates the neurons within the central nervous system and motor neurons which carries signals to effe...
