Document Summary
Filtration, excretion, electrolyte balance, acid-base balance (long term), endocrine functions - blood pressure (via renin secretion) and stimulating production of red blood cells (via erythropoietin) The kidneys lie against the posterior abdominal wall at the level of t12 to l3. Right kidney is slightly lower because of the liver. Rib 12 cross the approximate middle of the left kidney. Retroperitoneal, along with ureters, urinary bladder, renal artery and vein, and the adrenal glands. Renal artery and vein come off the abdominal aorta and the inferior vena cava respectively. Note: juxtamedullary nephrons have their blood flow through the vasa recta, rather than the peritubular capillaries. Glomerulus efferent arteriole peritubular capillaries interlobular v. arcuate v. interlobar v. Each nephron is composed of two principle parts renal corpuscle (which filters the blood plasma) and the. Inner layer of bowman"s capsule = consists of. Urinary poles of renal corpuscle proximal podocytes which wrap around the capillaries of the glomerulus.
