Compare the important physiological functions of the capillaries arising from the efferent arterioles of cortical nephrons to those arising from the efferent arterioles of juxtamedullary nephrons.
Answers
Explanation:
Vasodilation in the afferent arteriole and vasconstriction in the efferent arteriole will increase blood flow (and hydrostatic pressure) in the glomerulus and will increase GFR. Conversely, vasoconstriction in the afferent arteriole and vasodilation in the efferent arteriole will decrease GFR.
Answer:
Nephrons
structural and functional units of the kidney --> forms urine.
Renal corpuscle
the main site of filtration
Renal Tubule
processes filtrate into urine
Glomerulus
Ball like tuft of capillaries with fenestrated endothelium. highly porous.
Filtrate
fluid that passes from the blood through the capillary walls of the glomeruli of the kidney
Glomerular Capsule
cup-shaped hollow structure surrounding glomerulus. receives filtrate from glomerulus
parietal layer of glomerular capsule
simple squamous epithelium
visceral layer of glomerular capsule
clings to the glomerulus, consists of branching cells call podocytes, and plays an important role in the formation of filtrate
Podocytes
cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus
