Question

how do the urinary and circulatory systems interact to maintain homeostasis in humans?
○a. the kidneys produce growth hormones that are carried through the bloodstream to parts of the body where they are
needed.
○b. blood flows to the kidneys. cellular wastes are filtered from the blood and stored in the bladder until they are excreted
from the body.
○c. the kidneys transform food molecules into atp. this form of energy is carried by the bloodstream to muscles when
activity is needed.
○d. the kidneys produce wastes that are carried within the bloodstream to the arteries, where they are recycled into useful
products.

Explanation:

• Option A: Kidneys do not produce growth hormones. Growth hormones are mainly produced by the pituitary gland.
• Option B: The circulatory system (blood) flows to the kidneys (part of the urinary system). The kidneys filter cellular wastes from the blood. The filtered wastes are then stored in the bladder (urinary system) until excretion. This interaction helps maintain homeostasis by removing waste products from the body.
• Option C: Kidneys do not transform food molecules into ATP. ATP is mainly produced through cellular respiration in cells (e.g., mitochondria in cells).
• Option D: Kidneys filter wastes from the blood, and these wastes are excreted, not recycled into useful products in arteries.

Answer:

B. Blood flows to the kidneys. Cellular wastes are filtered from the blood and stored in the bladder until they are excreted from the body.
