The functional unit of the kidney is called: A nephron The renal cortex A glomerulus A neuron

This is the second twisted portion of the nephron after the Loop of Henle: a) Collecting duct b) Proximal tubule c) Bowman's capsule d) Distal tubule

One of the aides is taking pharm, and suggests that this patient might need a diuretic. What do you think? an osmotic diuretic might help this patient excrete water and correct their imbalances A potassium-wasting diuretic would be the best choice to correct this patient's imbalances A diuretic is just the wrong choice, this patient needs nasal ADH spray It would make more sense to give this patient ACE inhibitors to correct their electrolyte imbalances

What value provides the best estimate of renal function? a. What is a "normal" value for this measure?

Describe the functions of each of the following parts of the nephron and associated structures in the process of urine production: glomerulus, glomerular capsule, proximal convoluted tubule, peritubular capillaries, descending limb of the nephron loop, ascending limb of the nephron loop, distal convoluted tubule and collecting duct.

A person has a condition in which their endocrine system overproduces Antidiuretic Hormone (ADH). This hormone affects the function of the kidneys, which is part of the excretory system. If you were a doctor treating this patient, which symptom would be unusual for this patient? frequent urination dehydration fluid buildup in tissues extreme thirst

In the process of deamination, the liver converts amino acids into compounds that can be used in energy metabolism. The liver removes the amino groups from amino acids to produce urea.
