Urinary System

What is the role of the renal artery?

• To supply blood to the kidneys

• To filter waste from the blood

• To produce urine

• To regulate blood pressure

How is the glomerular filtration rate controlled intrinsically?

• Myogenic mechanism and tubuloglomerular feedback loop

• Hormonal regulation and neural control

• Increased blood pressure and decreased blood volume

• Renal clearance and osmotic pressure

What process removes toxins from the body?

• Digestion

• Urination

• Respiration

• Perspiration

What is the significance of the nephron loop (loop of Henle)?

• It filters blood and produces urine

• It regulates blood pressure

• Cortisol

• Insulin

What transports urine from the kidneys to the bladder?

• Ureters

• Urethra

• Bladder

• Kidneys

What is the primary functional unit of the kidney?

• Nephron

• Glomerulus

• Renal pelvis

• Ureter

What is the function of the collecting ducts in the nephron?

• To filter blood and produce urine

• To collect urine from multiple nephrons and transport it to the renal pelvis

• To reabsorb water and electrolytes

• To secrete hormones into the bloodstream

What does the renal corpuscle consist of?

• Glomerulus and Bowman's capsule

• Renal tubule and collecting duct

• Proximal convoluted tubule and distal convoluted tubule

• Ureter and bladder

What is the role of the renal vein?

• To supply blood to the kidneys

• To drain blood from the kidneys
