-
Functional unit of the kidney
Nephron
-
Consists of the glomerulus, and a glomerular capsule that encloses it
Renal corpuscle
-
Duct that leads away from the glomerular capsule and ends at the tip of the medullary pyramid
Renal tubule
-
Supplies blood to each of the nephrons
Afferent arteriole
-
Carries blood away from the glomerulus
Efferent arteriole
-
Ball of capillaries
Glomerulus
-
Encloses the glomerulus in a sphere like shape
Glomerular Capsule
-
Aka glomerular capsule
Bowman’s capsule
-
Arises from the glomerular capsule, longest region of the renal tubule
Proximal convoluted tubule
-
U shaped portion of the renal tubule, found primarily in the medulla
Nephron loop (Loop of Henle)
-
Very short section of the renal tubule, end of the nephron
Distal convoluted tubule
-
Receives fluid from the DCT of several nephrons
Collecting duct
-
Network of vessels that send blood to the renal medulla
Vasa recta
-
Network of capillaries that form around the renal tubule
Peritubular capillary
-
Constrict/dilate afferent arterioles, also respond to drops in blood pressure
Juxtaglomerular cells
-
Epithelial cells that are located at the end of the loop on the side facing the arterioles
Macula densa
-
Responsible for the reabsorption of sodium chloride
Ascending limb loop of Henle
-
End of the nephron loop where it reenters the renal cortex, the loop comes into contact with both afferent and efferent arterioles at the vascular pole of the renal corpuscle
Juxtaglomerular apparatus
