Phys 261 West Coast University Study Guide week 7 || Questions
and Correct Detailed Answers.
Renal Corpuscle correct answers The combination of glomerulus and Bowman's capsule.
Glomerulus correct answers A ball-like (knot) network of capillaries in the kidney that serves as
the site of filtration.
Proximal tubules correct answers Responsible for reabsorption of ions, H2O, and organic
molecules.
Osmoreceptors correct answers Sensory receptor that monitors extracellular fluid osmolarity.
Osmolarity is monitored by hypothalamic osmoreceptors (in the hypothalamus)
Juxtaglomerular cells/Aldosterone correct answers - Promotes sodium retention in the kidneys
acts on principal cells (P cells) of the distal nephron
- Hormone that enhances Na+-K+-ATPase activity and increases open time of Na+ and K+ leak
channels.
- Its secretion can be controlled directly at the adrenal cortex.
- Its secretion is also stimulated by angiotensin II.
ACE inhibitors correct answers - A.K.A angiotensin-converting enzyme inhibitor.
- Drug used to treat high blood pressure by blocking angiotensin-converting enzymes.
Angiotensin converting enzyme (ACE) converts ANG I to ANG II.
Hyperkalemia correct answers - increase in plasma potassium
- Acts directly on adrenal cortex cells to promote secretion of aldosterone.
Renin correct answers - Enzymes secreted by granular cells in the kidneys
, - Enzyme that converts angiotensin in the blood to angiotensin I
- The stimuli for its release are related either directly or indirectly to low blood pressure
Functions of the kidneys correct answers - Regulation of extracellular fluid volume and blood
pressure.
- Regulation of osmolarity.
- Maintenance of ion balance.
- Homeostatic regulation of pH.
- Excretion of wastes.
- Production of hormones.
Blood circulation through the kidney correct answers - Blood enters the kidney through the renal
artery.
- Renal portal system.
- Afferent arteriole.
- Glomerulus.
- Efferent arteriole.
- Peritubular capillaries.
- Peritubular capillaries converge to form venules and small veins.
- Blood flows out of the kidney through the renal vein.
Filtration correct answers The movement of fluid from plasma into Bowman's capsule.
Reabsorption correct answers The movement of filtered materials from tubule to blood.
secretion correct answers is the movement of selected molecules from blood to tubule.
