Free CUA Urologic Anatomy & Physiology Questions and Answers

Question 1

What is the primary function of the kidneys?

Accepted Answer

To filter blood and form urine

Answer

The kidneys are vital organs with the primary function of filtering blood to remove waste products, excess salts, and water. This filtration process results in the formation of urine, which is then excreted from the body. Beyond waste removal, kidneys also play crucial roles in regulating blood pressure, electrolyte balance, and red blood cell production.

Question 2

Which structure connects the kidney to the bladder?

Accepted Answer

Ureter

Answer

The ureters are muscular tubes that serve as the conduits for urine, connecting each kidney to the bladder. They transport urine from the renal pelvis of the kidneys down to the bladder through peristaltic contractions. This continuous flow ensures that urine produced by the kidneys is efficiently moved for storage.

Question 3

What is the role of the bladder?

Accepted Answer

Stores urine

Answer

The bladder is a muscular, expandable sac located in the pelvis, primarily responsible for storing urine. It collects urine produced by the kidneys and holds it until it is convenient for the individual to urinate. This storage capacity allows for intermittent urination and prevents continuous leakage.

Question 4

Which part of the nephron is responsible for filtration?

Accepted Answer

Glomerulus

Answer

The glomerulus is a key component of the nephron, the functional unit of the kidney, and is solely responsible for the initial filtration of blood. It is a network of tiny capillaries that filters water, salts, glucose, amino acids, and waste products from the blood, forming a filtrate that then enters the renal tubule for further processing.

Question 5

What hormone regulates water reabsorption in the kidneys?

Accepted Answer

Antidiuretic hormone (ADH)

Answer

Antidiuretic hormone (ADH), also known as vasopressin, is a crucial hormone that regulates water reabsorption in the kidneys. It acts on the collecting ducts to increase their permeability to water, allowing more water to be reabsorbed back into the bloodstream. This mechanism helps the body conserve water and concentrate urine, especially during dehydration.
