A
They carry blood directly from the renal artery to the glomerulus.
B
They surround the renal tubules and are involved in reabsorption and secretion.
C
They are responsible for the production of urine.
D
They are part of the glomerular filtration process.
Verified step by step guidance1
Understand the role of peritubular capillaries in the kidney. They are small blood vessels that surround the renal tubules.
Recognize that peritubular capillaries are involved in the processes of reabsorption and secretion, which are crucial for modifying the filtrate into urine.
Clarify that peritubular capillaries do not carry blood directly from the renal artery to the glomerulus; this is the role of the afferent arterioles.
Note that peritubular capillaries are not directly responsible for the production of urine; they assist in the modification of the filtrate after glomerular filtration.
Understand that peritubular capillaries are not part of the glomerular filtration process itself; they function after filtration to reabsorb necessary substances and secrete waste products.
