In a nephron, the long tubular passageway through which the filtrate passes includes:

The three processes involved in urine formation are:

The primary site for secretion of substances into the filtrate is the:

Dilation of the afferent arteriole and glomerular capillaries and constriction of the efferent arteriole causes:

Blood supply to the proximal and distal convoluted tubules of the nephron is provided by the:

The glomerular filtration rate is regulated by:

Dropping filtration pressure stimulates the juxtaglomerular apparatus to release angiotensin.

The primary site of nutrient reabsorption in the nephron is the:

In countercurrent multiplication, the countercurrent refers to the fact that an exchange occurs between:

When antidiuretic hormone levels rise the distal convoluted tubule becomes:

The results of the effect of aldosterone along the DCT, the collecting tubule, and the collecting duct are:

The average pH for normal urine is about:

When urine leaves the kidney it travels to the urinary bladder via the:

Contraction of the muscular bladder forces the urine out of the body through the:
