Renal tubule and glomerulus

Where does the glomerulus funnel blood into after it leaves the afferent arteriole?

Efferent arterioles

What part of the nephron is known as the loop of Henle?

Nephron loop

Which of the following statements about the juxtaglomerular cells is correct?

They are smooth muscle cells located near the glomerulus and respond to changes in blood pressure and blood volume.

What is the primary function of the macula densa cells?

To sense changes in glomerular filtration rate based on the quantity of sodium and chloride ions flowing through the tubule.

Which of the following statements about the sympathetic nervous system's role in regulating blood pressure is correct?

All of the above statements are correct.

Which of the following statements about the filtration process in the nephron is correct?

As filtrate makes its way through the renal tubule, waste and molecules like ions and water are exchanged between the tubule until, finally, urine is formed.

What is the correct sequence of events in the formation of the renal vein?

The peritubular capillaries reunite to form larger and larger venous vessels, which eventually form the renal vein that drains into the inferior vena cava.
