Question

urinary bladder urethra kidneys urinary system is involved in maintaining the salt and water balances within the body. \\(\boldsymbol{1}\\) which statement describes how the organization of the urinary system and one other system interact to maintain homeostasis in the human body? (1) the skeletal system, part of the endocrine system, delivers nutrients to the cells of the urinary system to remove wastes from the blood (2) the internal urethral sphincter muscle, part of the muscular system, contracts to signal the cells of the urinary system to regulate blood sugar. (3) the brain, part of the nervous system, sends messages to the renal pelvis (nerves) to signal the cells of the urinary system to deliver oxygen to the blood. (4) the arteries, part of the circulatory system, deliver oxygenated blood to the cells of the urinary system to remove wastes.

Explanation:

Step1: Analyze each option

We evaluate which option correctly shows interaction between the urinary system and another system for homeostasis:

1. The adrenal gland (endocrine system) does not deliver nutrients; it produces hormones that regulate water/salt balance (related to urinary function), so this statement is incorrect.
2. The internal urethral sphincter is part of the urinary system, not the muscular system, so this statement is incorrect.
3. The brain (nervous system) sends signals via renal plexus nerves to the urinary system, and this neural control helps regulate urine production/ excretion, which maintains water/salt homeostasis. This is a correct interaction.
4. Arteries deliver filtered blood to the kidneys (urinary system), not unfiltered, so this statement is incorrect.

Answer:

(3) The brain, part of the nervous system, sends messages to the renal plexus (nerves) to signal the cells of the urinary system to deliver oxygen to the blood.
