Answer:
The answer is 1) Pylorus, 2) Mesentery
Explanation:
The small intestine extends from the stomach at the level of the pylorus, to the large intestine. It is suspended in the abdomen by the mesentery that fixes it to the posterior abdominal wall.
The mesentery is a thin sheet of tissue, continuation of the peritoneum that is made up of two portions, one internal or visceral and the other external or parietal.
Answer:
Are there any structures within the heart or vessels that prevent the backflow of blood? If so, what are they and where are they located?
Explanation:
<em>The heart is made up of four cavities. These are the following</em>: Two ventricles and Two atria.
<em>The left ventricle is the one that exerts the greatest muscular strength, because from here the blood is pumped to the systemic circulation. To prevent blood from flowing backward between two beats, there are several types of heart valves</em>: one type between the atria and the ventricles, and another between the ventricles and arteries.
The semilunar valves in turn prevent blood from returning from the pulmonary artery and the aorta to the ventricles, when after pumping they dilate again for muscle relaxation.
<u><em>The answer is</em></u>: <u>Yes, and they are semilunar valves.</u>
Environmental hazards—such as water and air pollution, extreme weather, or chemical exposure—can affect human health in many ways, from contributing to chronic diseases such as cancer to acute illnesses such as heat exhaustion.
