Answer:
Myogenic mechanisms
Hormones
Sympathetic nervous system
Explanation:
Myogenic mechanisms work in the arterioles that serve the glomerulus.
They cause the smooth muscle cells in the arterioles to contract and relax in response to blood pressure changes.
The sympathetic nervous system increases blood flow through the kidneys during resting conditions.
At times of stress, it decreases blood flow through the kidneys, making it more available to the rest of the body.
The hormones angiotensin and aldosterone regulate blood volume by controlling retention of Na⁺ and water.
C is wrong. The parasympathetic nervous system mainly controls visceral organs such as glands.
The answer is D, tissue. A group of cells makes a tissue and tissues make organs, joints, and connections.
