Urinary System

What substances are typically reabsorbed in the proximal convoluted tubule?

• Glucose, amino acids, and electrolytes.

• Urea, creatinine, and uric acid.

• Sodium, potassium, and chloride.

• Bicarbonate, phosphate, and sulfate.

What is another term for the urge to urinate?

• Micturition reflex

• Urinary retention

• Incontinence

• Dysuria

What is the order of the renal tubule regions starting from the renal corpuscle?

• Proximal convoluted tubule, loop of Henle, distal convoluted tubule

• Distal convoluted tubule, proximal convoluted tubule, loop of Henle

• Loop of Henle, proximal convoluted tubule, distal convoluted tubule

• Proximal convoluted tubule, distal convoluted tubule, loop of Henle

What is the role of the loop of Henle in the nephron?

• Concentration of urine through the reabsorption of water and salts.

• Filtration of blood to remove waste products.

• Production of hormones that regulate blood pressure.

• Storage of urine before excretion.

What is the basic functional unit of the kidney?

• Nephron

• Glomerulus

• Renal pelvis

• Ureter

What is the process of micturition?

• The act of expelling urine from the bladder.

• The process of digestion in the stomach.

• The absorption of nutrients in the intestines.

• The secretion of hormones from the kidneys.

What is the composition of normal urine?

• Water, urea, uric acid, creatinine, and electrolytes.

• Water, glucose, amino acids, and proteins.

• Water, urea, creatine, and hormones.

• Water, uric acid, and fatty acids.

What is the significance of the renal corpuscle?

• It is the site of blood filtration in the nephron.

• It produces urine in the collecting duct.

• It regulates blood pressure in the glomerulus.

• It absorbs nutrients in the proximal tubule.

What is the primary function of the proximal convoluted tubule in the nephron?

• Filtration

• Secretion

• Reabsorption

• Excretion

What is the role of the collecting duct in the urinary system?

• It collects urine from multiple nephrons and regulates water reabsorption.

• It filters blood to form urine.

• It produces hormones that regulate blood pressure.

• It transports urine from the kidneys to the bladder.
