Section 1

Question Answer
Renal capsuleFibrous layer of connective tissue.
UreterThe tubes that connect the kidneys to the bladder. Transports urine to bladder.
UrethraThe tube that drains the bladder. Conveys urine to exterior.
Fluid balanceThe amount of water you gain each day is equal to the amount you lose to the environment.
FiltrationAccures solely on the bases of size.

Section 2

Question Answer
ReabsorptionThe removal of water and solute molecules from the filtrate, and their reentry into the circulation at the peritubular capularies.
SecretionThe transport of solutes out of the peritubular capillaries into the filtrate.
KidneyBean shaped organs that produce urine and helps regulate body fluids.
BladderThe place where urine is stored until urination.
NephronThe microscopic kidney structure that filters the blood.

Section 3

Question Answer
GlomerulusA "ball of capillaries" within each nephron.
Bowman's capsulesCollects fluid filtered through glomerulus. Double layered membrane.
HilumThe "notch" in each kidney where the renal artery, renal vein, and ureter attach.
UTIA term for an infection involving the kidneys, ureters, or bladder

Section 4

Question Answer
Renal pelvisFunnels urine from the kidney into the ureter.
Renal medullaThe middle layer of the kidney.
Renal cortexThe outer layer of the kidney.
Renal arteryMajor artery that carries blood to the kidney.
Renal veinMajor blood vessels that carries blood away from the kidneys.
Renal failureImpared functioning of the kidneys leading to a build-up of toxic waste products and fluids in the body.

Section 5

Question Answer
Fluid passing from the glomerulus into the glomerular capsule is undergoing...Filtration
Fluid normally found inside the glomerular capsule...Plasma
When substances are removed from renal tubules and returned to the blood stream...Reabsorption
This hormone is secreted by the hypothalamus when blood pressure decreases or ionic concentration increases; it results in increased reabsorption of water in the nephron...Antidiuretic hormone
This hormone is secreted by the adrenal cortex and affects sodium and potassium processing by the nephron...Aldosterone

Section 6

Question Answer
Distal tubuleTubule of the nephron that begins at the loop of Henle. It empties into the collecting duct. Reabsorption takes place there.
Proximal tubuleThe part of the renal tubule closest to the glomerulus. Many substances are secreted or absorbed in this part of the renal tube.
Afferent arteriolesSmall arteries traveling toward and organ.
Efferent arterioleSmall blood vessels that carry blood away from the glomeruli of the kidney.
