This is a nephron process that results in a substance in blood entering the already formed filtrate.

The proximal convoluted tubules reabsorb which percentage of filtered water?

This substance gives bile its major pigmentation:

This term means the return of substances into the blood stream from the filtrate.

Describe in detail how the renin angiotensin negative feedback loop helps regulate blood pressure and glomerular filtration rate in response to dehydration.

This occurs when a substance passes from the fluid in the tubular lumen through the apical membrane,across the cytosol,and then into the interstitial fluid.

This layer's main function is to protect the kidney from trauma and hold it in place within the abdominal cavity.

Which structure of the nephron reabsorbs the most substances?

Excessive urine concentration of a normal breakdown product of hemoglobin,caused by pernicious anemia,infectious hepatitis,jaundice or cirrhosis,indicates which condition?

This occurs when stretching triggers contraction of smooth muscle walls in afferent arterioles.

Fluid flowing from point H in the figure will go to which structure next?

This is the structure of the nephron that filters blood.

Which is the correct order of blood flow through the kidneys?

Where is the corticomedullary junction?

Urine formed by the nephrons first drains into these.

Stress,causing excessive amounts of epinephrine secretion which stimulates glycogen breakdown,indicates which condition? This condition can also indicate diabetes mellitus.

Which of the following is a waste product normally excreted by the kidneys?

Anorexia,starvation,or a diet too low in carbohydrates indicates which condition?
