Question

Match the function of the urinary system to the human organ system in the key. a. muscular system b. nervous system c. endocrine system d. cardiovascular system e. respiratory system f. digestive system g. reproductive system \(\mathrm{ADH},\) aldosterone, and atrial natriuretic hormone regulate reabsorption of \(\mathrm{Na}^{+}\) by kidneys.

Short answer

The urinary system is most closely associated with the endocrine system (c), as it involves the secretion of hormones such as ADH, aldosterone, and atrial natriuretic hormone, which regulate the function of the kidneys in maintaining proper ion balance and blood pressure.

Step-by-step solution

Analyze the function of the provided hormones

ADH (antidiuretic hormone), aldosterone, and atrial natriuretic hormone all have roles in regulating water and electrolyte balance in the body. Their primary target is the kidney, which is responsible for filtering toxins and waste from the body.

Determine the organ system associated with the kidneys

The kidneys belong to the urinary system, which is responsible for filtering toxins and waste from the body, maintaining a proper balance of ions, and regulating blood pressure. The urinary system is primarily involved in controlling the composition, volume, and pressure of blood.

Match the function to the organ system in the key

Based on the functions of the kidneys and the hormones provided, the urinary system is most closely associated with the endocrine system (c). The endocrine system is responsible for regulating various functions in the body by secreting hormones. These hormones affect processes such as metabolism, growth, and reproduction and influence the function of other organ systems, like the urinary system. In this case, the secretion of ADH, aldosterone, and atrial natriuretic hormone (which all play a role in regulating the function of the kidneys) are aspects of the endocrine system. So, the answer is (c) endocrine system.
