Juxtamedullary nephrons none of these O have very short nephron loops. make up about 80-85% of the nephrons within the kidney. O allows excretion of very concentrated urine.

The visceral layer of a renal capsule consists of unusual, branching epithelial cells called: O loops of Henle podocytes O pericytes filtration slits

Several pharmacological agents have been shown to lower the pressure of the filtrate inside the lumen of nephrons. What affect will this have?     a hydrostatic pressure of fluid in the Bowman’s capsule increases, GFR increases     b hydrostatic pressure of fluid in the Bowman’s capsule decreases, GFR decreases    c hydrostatic pressure of fluid in the Bowman’s capsule increases, GFR decreases    d hydrostatic pressure of fluid in the Bowman’s capsule decreases, GFR increases

The glomerular filtrate contains a lower concentration of than does blood plasma. glucose O albumin O sodium water

The cortical nephron is characterized by all of the following except:   a. short nephron loop   b. glomerulus is further from the cortex-medulla junction   c. glomerulus is close to the cortex-medulla junction   d. efferent arteriole supplies peritubular capillaries

Renal filtration is the movement of water and solutes out of the ____ and into the _____. Group of answer choices afferent arteriole; glomerulus efferent arteriole; glomerulus glomerulus; Bowman’s capsule glomerulus; efferent arteriole

e nephron filters blood from the arterioles into the tubules duct capsule erular apparatus nephron loop

Answer these questions the kidneys and blood pressure. o Why do the kidneys have control over blood pressure? o What structure(s) within the nephron control blood pressure and what pathway do they initiate? o What is one response, triggered by the pathway above, within the body that increases blood pressure. Be specific.

Fill in the blank part of kidney nephron is illustrated

"The majority of the nutrients, salt, and water that are filtered are reabsorbed in the _____."     proximal convoluted tubule     distal convoluted tubule     descending nephron loop     ascending nephron loop     collecting duct
