Explain the three main functions of the kidney in maintaining homeostasis.

The three main functions of the kidney in maintaining homeostasis are regulatory, excretory, and endocrine functions.

What is the composition of the renal corpuscle and what are the two types of nephrons exiting from it?

The renal corpuscle is made up of the glomerulus and Bowman’s capsule. The two types of nephrons exiting from it are cortical nephrons (80%) and juxtamedullary nephrons (20%).

What is the main function of the juxtamedullary nephrons?

The main function of the juxtamedullary nephrons is to enable the kidney to determine the concentration of the urine.

Describe the processes of tubular reabsorption and tubular secretion in the nephron.

<p>Tubular reabsorption is the reabsorption of solutes along the tubule back into the peritubular capillary. Tubular secretion is the material secreted into the tubular fluid to remove substances from the blood.</p> Signup and view all the answers

Where does the majority of reabsorption occur in the nephron, and what are the specific processes occurring in the descending and ascending loops of Henle?

<p>Two-thirds of reabsorption occurs at the proximal convoluted tubule. Water reabsorption occurs in the descending loop of Henle, followed by solute reabsorption in the ascending loop of Henle.</p> Signup and view all the answers
