Which of the following is the correct sequence regarding the flow of waste products through the nephrons of the kidneys?
glomerular capsule, proximal convoluted tubule, collecting duct, nephron loop, distal convoluted tubule
glomerular capsule, proximal convoluted tubule, distal convoluted tubule, nephron loop, collecting duct
glomerular capsule, proximal convoluted tubule, nephron loop, distal convoluted tubule, collecting duct
glomerular capsule, collecting duct proximal convoluted tubule, nephron loop, distal convoluted tubule.
One of the many functions of the nephrons is to put water back into the bloodstream to prevent dehydration. In order to accomplish that task, which hormone is involved?
ANP
ADH
Angiotensin
Cortisol
Which of the following is correct regarding the renin‐angiotensinogen mechanism?
A decrease in blood pressure results in the release of renin which converts angiotensinogen I to angiotensinogen II. The angiotensin‐converting enzyme converts angiotensinogen II to angiotensin, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.
A decrease in blood pressure results in the release of renin which converts angiotensinogen to angiotensin I. The angiotensin‐converting enzyme converts angiotensin I to angiotensin II, which stimulates the adrenal cortex to secrete aldosterone, a hormone that is involved in increasing blood pressure.
A decrease in blood pressure results in the release of angiotensin‐converting enzyme, which converts angiotensin to angiotensinogen I. The angiotensin‐converting enzyme then converts angiotensinogen I to angiotensinogen II. Angiotensinogen II then stimulates the adrenal cortex to secrete renin, which is involved in increasing blood pressure.
The renal pyramids are separated from each other by extensions of the renal cortex called ________.
renal medulla
minor calyces
medullary cortices
renal columns
Blood filtrate is captured in the lumen of the ________.
glomerulus
Bowman’s capsule
calyces
renal papillae
Which pressure helps filtration to occur on bowman's capsule?
glomerular hydrostatic pressure
Colloid osmotic pressure
Capsular hydrostatic pressure
oncotic pressure
Which hormone will cause reabsorbtion of Na+ and water and increase secretion of H+ and K+ in the urine?
