Answer

Reabsorbing sodium ions

Answer

Synthesizing antidiuretic hormone (ADH)

Answer

Filtering blood

Question 7

The outermost layer of the kidney is the:

Accepted Answer

Capsule

Answer

Cortex

Answer

Medulla

Answer

Pelvis

Question 8

In clinical practice, urinary system disorders are prevalent. Discuss their implications, focusing on the common conditions of urinary tract infections (UTIs) and kidney stones.

Accepted Answer

Early detection and proper management of urinary system disorders can prevent serious complications and improve patient outcomes.

Answer

UTIs and kidney stones are rare and have minimal clinical significance.

Answer

UTIs primarily affect the upper urinary tract, while kidney stones are confined to the lower urinary tract.

Answer

Urinary system disorders have no significant impact on overall health and well-being.

Question 9

How does antidiuretic hormone (ADH) contribute to regulating water homeostasis and urine concentration?

Accepted Answer

ADH promotes water reabsorption in the collecting ducts, resulting in more concentrated urine.

Answer

ADH increases urine output by inhibiting water reabsorption in the collecting ducts.

Answer

ADH acts on the kidneys to decrease blood pressure by dilating blood vessels.

Answer

ADH is released in response to a decrease in blood pressure.
