The kidney is composed of an outer cortex and inner medulla. The basic functional unit of the kidney is the nephron, which contains the renal corpuscle and renal tubule. The renal corpuscle is located in the cortex and consists of the glomerulus and Bowman's capsule. The renal tubule contains the proximal convoluted tubule, loop of Henle, and distal convoluted tubule. The medulla contains only straight tubules like the loop of Henle and collecting ducts.
Kidney(General Anatomy and Histology)
- 1. Kidney M. FARAN YOUSAF KBCMA College of Veterinary and Animal Sciences, Narowal.
- 2. Outline: Introduction Nephron Cortex Renal Corpuscle Renal Tubules Medulla
- 3. Introduction: Kidneys are paired structures functioning in filtration of blood. Mostly bean shaped in all species. Divided into renal cortex and medulla. Outside covered with thick connective tissue called Capsule.
- 8. Nephron: Basic functional unit of kidney. Has 2 main portions: Renal corpuscle: i.Glomerulus ii.Bowmans capsule Renal tubule: i.Proximal convoluted tubule ii.Loop of Henle iii.Distal convoluted tubule
- 9. Position of Juxtamedullary nephron in kidney
- 10. Renal Cortex: Outer-dark red portion Divides into: Cortical labyrinth(pars convoluta) Medullary rays(pars radiata) Composed of both straight tubules and convoluted tubules. Renal corpuscle is present only in renal cortex. PCT and DCT are also present.
- 11. Renal corpuscle: It consists of Glomerulus Bowmans capsule Additionally, present things are: Mesangium Macula densa
- 12. PCT and DCT: PCT contains brush borders while DCT dont have any brush borders. So thats an important point in their identification.
- 14. Renal Medulla: Inner lighter-colored portion Only contains straight tubules (Loop of Henle and Collecting ducts) Loop of Henle = simple squamous Ep. Collecting ducts = Simple columnar Ep.
