Quiz 1
Although we haven't covered these systems in detail yet, which of the following systems would involve gas exchange of CO2 and O2?
I only chose respiratory as an answer. However, the correct answers are respiratory and cardiovascular because of the pulmonary circulatory system. Gas exchange occurs at pulmonary capillary beds.
Why does O2 say, "...if Glucose can't get in, how can I do my job?"
I should read the article more carefully. I answered O2 has nothing to do with cellular respiration and it is wrong. According to the article, page 5, O2 said cellular respiration requires both myself (O2) and glucose by facilitated diffusion. The correct answer is oxygen and glucose work together to produce ATP. ATP molecules are yield during cellular respiration.

I should remember the lecture note that parafollicular cells of the thyroid gland produce calcitonin.
Which of the following is/are not considered a "con" of hormone replacement therapy (HRT)?
The correct answer is bone fractures because HRT slows bone turnover and increase bone mineral density which are good for reducing bone fracture.
Osteoporosis may be described in many ways. Which of the following accurately characterizes osteoporosis? More than one may apply.
I should not include estrogen increase osteoblast apoptosis and thereby decreases the onset of osteoporosis. Estrogen promote osteoblast by limiting apoptotic cell death which leads decrease bone fragility and fractures. Estrogen can promote osteoblast viability by increasing osteoblast resistance to apoptosis.
Quiz 5

    Osteoporosis comes from the latin word meaning “porous bone”. If you were to look closely at a bone you could see there are these small spaces on the bone which is good, now if you look at someone who suffers from osteoporosis you will see these spaces are much larger. As these spaces become larger it takes away from the strength and integrity of the bone making it grow weak and thin. Osteoporosis is most common in women over the age of 50 and gives them a higher risk of fractures and or breaks especially common in the hips. While we know osteoporosis comes from a number of things it can be broken down to age, the hormonal changes most commonly seen in menopause and a lower intake of Vitamin D and Calcium. Age is the unpreventable factor that doctors or you cannot change. Hormonal changes can be fixed with supplements or hormone therapy along with ones intake of Vitamin D and Calcium. Hormone therapy, estrogen alone or the combination of estrogen and progestin have been proven to prevent and aide in the treatment of osteoporosis in

  • Disease Effects Of Osteoporosis

    950 Words  | 2 Pages

    There are many different diseases that can affect our skeletal system and Osteoporosis is one of them. Osteoporosis lessens bone strength and bone density (amount of bone mineral in bone tissue), which will lead to fragile bones. It mainly affect the hips, ribs, spine, and wrists. Male or female, at any age, can get this but it is mostly occurs in older women (Team, 2016). Osteoporosis is very common, there are more than 3 million cases a year. There are many causes/risk factors, symptoms, and some treatment cases. About 54 million Americans have Osteoporosis and low bone mass (Foundation, 2016).

    both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the

    It is when much needed oxygen is obtained by the body in order for respiration to take place and the waste CO2 is taken out of the body. In us mammals, the exchange takes place in the lungs which contain a large number of alveoli. These are sponge-like structures in which the diffusion takes place. They are highly adapted to diffuse the gases as they give a large surface area for exchange of the gases.

  • Essay On Osteoporosis

    916 Words  | 2 Pages

    Osteoporosis Osteoporosis is a systemic, debilitating disease of the skeleton, characterized by significantly decreased bone mass in combination with the deterioration of bone microarchitecture. Osteoporosis has three types of categories, the first category is type 1 which occurs in women after menopause and results from declining levels of estrogen and other sex hormones in the body, this could also occur in men due to low levels of the sex hormone testosterone. Type 2 is called Senile Osteoporosis, which occurs in elderly men as well as elderly women because of decreased bone formation due to aging. Type 3 is caused by long-term use of medication, usually with steroids and drugs, to treat elipsy. Osteoporosis, which literally means “Porous Bone”, is a disease in which the density and quality of bone are reduced (Kackowski, 2013).

    The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make

    They are the same reactions, but occur in reverse. In photosynthesis, carbon dioxide and water yield glucose and oxygen respiration, process glucose and oxygen yield carbon dioxide and water, catabolic pathway process which requires or contains molecular oxygen for the production of adenosine triphosphate. This three step aerobic respiration cycle occurs in the cytoplasm and in the organelles called mitochondria. Within this process, cells break down oxygen and glucose in a storable form called adenosine triphosphate or ATP. This cellular respiration or sometimes called an exothermic reaction is similar to a combustion type reaction whereby the cell releases energy in the form heat but at a much slower rate within a living cell.

    Osteoporosis is a disease in which the bones become so weak and brittle that even a cough can cause enough stress on the bone that it will cause the bone to facture. The most commonly broken bones are the hip, wrist, and the spine. Although it affects men and women of all races, post-menopausal Caucasian and Asian women are more commonly affected than those of other ethnicities and sexes. In fact, thirty percent of all post-menopausal women in the US and Europe will be diagnosed with Osteoporosis and at least 40 percent of those will suffer from a fracture in their lifetime.
