Answer:
D. Decreasing vessel diameter
Explanation:
Cardiac output is the amount of blood pumped per unit time by heart. Increased cardiac output corresponds to increased blood pressure which will result in increased blood flow. In vasodilation the smooth muscles within the blood vessels relax making them wide hence decreasing vascular resistance leading to more blood flow. Decreased blood viscosity will also decrease the resistance to blood flow.
Decreasing vessel diameter will not increase the blood flow, it will rather restrict it because there will be more resistance to passage of blood due to small space.
Answer:
Parathyroid (PTH)
Explanation:
In the kidney, parathyroid hormone (PTH) blocks reabsorption of phosphate in the proximal tubule while promoting calcium reabsorption in the ascending loop of Henle, distal tubule, and collecting tubule. Parathyroid hormone (PTH) promotes absorption of calcium from the bone in 2 ways.
Answer:
The digestion of carbohydrates begins in the mouth and ends in the small intestine.
Explanation:
The absorption of carbohydrates, depending on whether they are simple or complex, will begin their digestion in the mouth by the action of saliva in food, where starches are initially separated; Once this food bolus reaches the stomach, the hydrochloric acid acts, to end later in the small intestine. Amylase, a component of pancreatic juice, ends the digestive process of carbohydrates by transforming starches into maltose, which are then transformed into monisacarides (glucose, galactose, fructose), which is the way they are absorbed by the body. In the liver they are again transformed into glucose.
Answer:
a. True
Explanation:
Endothelial cells
These cells are found in all the parts of the circulatory system , these are about a cell thick , and composes a wall known as the edothelium , which lines all the blood vessels , i.e. , the arterioles , veins , capillaries , arteries , venules .
Beneath the endothelial cells , there is a layer of smooth muscle cells .
