Produce urine
Which of the following is part of the renal tubule?
a. PCT (proximal convoluted tubule) b. Loop of Henle c. DCT (distal convoluted tubule) d. Collecting duct
Where does bulk reabsorption occur in the renal tubule?
PCT
What determines the final urine composition and volume?
Collecting duct
What does excretion in the kidneys do?
Removal of wastes from body fluids in urine
Where does urine production start?
Nephron
What is the outer portion of the kidney called?
Renal cortex
What does Glomerulus do?
Filters small solutes from the blood
Where do aquaporins allow water to pass from the filtrate into the interstitial fluid?
Descending loop of Henle
Which of the following is NOT part of the renal corpuscle?
Distal convoluted tubule
Where does protein-free filtrate travel?
Renal Tubule
What structure is composed of descending and ascending limb?
The Loop of Henle
What is the last segment of the renal tubule?
DCT
Where do further adjustments to the filtrate occur?
DCT
What type of cells line the DCT?
Epithelial cells
What acts as a funnel to drain urine from the kidney to the ureter?
Renal pelvis
Ureter transports urine toward the
urinary bladder
Urinary bladder temporarily stores urine prior to
elimination
_____conducts urine to exterior
Urethra
Kidneys are composed of nephrons along with a
collecting system
The three processes in the function of kidneys are
filtration, reabsorption, and excretion
The _____________ is the outer shell of the kidney
renal capsule
The renal medulla is composed of
renal pyramids, renal columns, minor calyx, and major calyx
Ascending loops of Henle reabsorbs ________ from the filtrate into the interstitial fluid
Na+ and Cl-
The proximal convoluted tubules remove _____ and adjusts _____
toxins, filtrate pH
The distal tubule selectively secretes and absorbs different ions to maintain
blood pH and electrolyte balance.
When considering the glomerulus, it receives blood from the
afferent arteriole
The Bowman’s capsule surrounds the
glomerulus
DCT cells are _____ active than of the PCT cells
less
Epithelial cells lining the DCT are _________ than those of the PCT and do NOT have ______
smaller, microvilli
Angiotensin causes ________ by the adrenal cortex
vasoconstriction and segregation of aldosterone
________ lines urinary bladder and ureters
Urothelium
What chamber of the heart pumps low oxygen blood to the lungs?
right ventricle
What chamber of the heart collects high oxygen blood via the right and left pulmonary veins?
left atrium
What chamber of the heart collects high oxygen blood via the right and left pulmonary veins?
left ventricle
What circuit carries blood to the body?
system circuit
What circuit carries blood to the lungs?
pulmonary circuit
What closes when ventricles contract?
atrioventricular valves
What are the cells in the SA node called?
pacemaker cells
What is the parasympathetic stimulation of the heart responsible for?
decreasing heart rate
What leads to vasoconstriction

tissue of tunica intima
endothelial cells and connective tissue
tissue of tunica media

lymphocytes
what system is the venous system
low blood pressure, high volume
name the function of platelets
clotting
name the function of red blood cells
