Components of the Nephron
Renal Corpuscle, Proximal convoluted tubule, Henle's loop, and distal convoluted tubule
What makes up the renal corpuscle?
The glomerulus + glomerular (Bowman's) capsule
What is the glomerulus
capillary network that receives blood via the afferent arteriole and sends it away via the efferent arteriole
Glomerular (Bowman's) capsule
cup-shaped structure that surrounds the glomerulus
What is the function of the proximal convoluted tubule?
1) Reabsorption of the majority of water in the filtrate (osmosis)
2) Active reabsorption of ions, amino acids, glucose to the blood
3) Secretion of large or highly-charged particles
What is the function of the descending limb of the Loop of Henle?
Reabsorption of Na, Cl, and water
What are the characteristics of the ascending limb of the Loop of Henle?
Impermeable to water, but Na and Cl moves into interstitium
What is the function of the distal convoluted tubule?
Reabsorbs bicarbonate and secretes ammonium ion and hydrogen.
What is the function of the collecting tubule, collecting duct, and papillary duct?
receives filtrate (now urine) from nephrons and releases it into MINOR CALYX. Absorption controlled by antidiurectic hormone (ADH), which is secreted by the pituitary gland.
