Study Notes
Nephron Structure and Function
- The PCT (Proximal Convoluted Tubule) and DCT (Distal Convoluted Tubule) are situated in the kidney.
- The vasa recta capillary network runs parallel to the loop of Henle and forms a 'U' shape.
- Nephrons with a very long loop of Henle extending deep into the medulla are termed juxtamedullary nephrons.
- The renal corpuscle is responsible for urine formation through processes like glomerular filtration.
- In cortical nephrons, the vasa recta is either absent or highly reduced compared to juxtamedullary nephrons.
- The primary function of the peritubular capillaries is to reabsorb and secrete substances.
- The DCT is distinguished from the PCT by its smaller diameter and thicker epithelial lining.
- The collecting ducts of many nephrons converge in the renal pyramid before opening into the renal pelvis.
- The efferent arteriole emerging from the glomerulus forms a fine capillary network around the renal tubule.
- In cortical nephrons, the vasa recta is either absent or highly reduced.
- The next part of the tubule after the hairpin-shaped Henle's loop is the DCT.
- The distal convoluted tubule opens into a straight tube called the collecting duct.
