Question

Quizplus · Accepted Answer

Hemoglobin is a protein found in red blood cells that binds and transports oxygen, but it does not play a role in regulating blood volume. Antidiuretic hormone (ADH), aldosterone, and atrial natriuretic hormone (ANH) all play a role in regulating blood volume by influencing water and electrolyte balance in the body. Nitric oxide is a vasodilator that helps regulate blood pressure but does not directly impact blood volume.
