Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The walls of blood capillaries in the kidney are fenestrated. How does the fenestration of these capillaries help in the production of urine?
A
A larger volume of fluid can be filtered out of the blood per minute.
B
Small molecules are allowed through but not large ones.
C
Higher blood pressures can be tolerated without damage to the capillaries.
D
Phagocytes are able to escape from the capillaries and prevent kidney infections
Explanation: 

Detailed explanation-1: -The walls of blood capillaries in the kidney are fenestrated. How does the fenestration of these capillaries help in the production of urine? A larger volume of fluid can be filtered out of the blood per minute.

Detailed explanation-2: -Continuous fenestrated capillaries have larger openings (fenestrations) between the cells that allow the quick exchange of substances. These substances include nutrients and blood.

Detailed explanation-3: -Fenestrated capillaries work with the rest of your circulatory system to move nutrients, waste and oxygen through your body. These little blood vessels play an essential role in helping your kidneys filter waste and create urine.

Detailed explanation-4: -These capillaries can be found in tissues where a large amount of molecular exchange occurs, such as the kidneys, endocrine glands, and small intestine. They are particularly important in the glomeruli of the kidneys, as they are involved in filtration of the blood during the formation of urine.
