What is renal cortex
100
dark brown internal layer (kidney)
What is renal medulla
100
triangular wedges comprising the medulla
What is renal pyramids
100
extensions of corticol tissue between pyramids
What is renal columns
100
large sac that collects all urine from kidney
What is renal pelvis
200
small cup-like cavities at tips of pyramids
What is minor calyces
200
larger cavities draining minor calyces
What is major calyces
200
carries blood to the glomerulus
What is afferent arteriole
200
drains blood from glomerulus
What is efferent arteriole
200
capillary network within Bowman's capsule
What is glomerulus
300
blood vessel that carries blood away from the kidney and towards the heart
What is renal vein
300
blood vessel that carries blood to kidney
What is renal artery
300
major nitrogenous waste excreted in urine
What is urea
300
tube leading from urinary bladder to outside of body
What is urethra
300
kidneys filter the blood to remove waste products, maintain electrolyte concentrations, and remove excess water to maintain the fluid volume within the body
What is kidney
400
microscopic units of kidneys that produce urine
What is nephron
400
liquid waste products to be excreted
What is urine
400
tubes that carry urine from the kidneys to the bladder
What is ureters
400
hollow, muscular sac that holds urine
What is urinary bladder
400
a series of wave like contractions which move urine down each ureter to the bladder
What is peristalsis
500
the return of blood of some of the substances that were removed during filtration
What is reabsorption
500
process whereby some substances, but not all, pass through a filter. In the kidney, blood pressure forces materials through the filter (glomerulus)
What is filtration
500
chemical element that carries electrical charge when dissolved in water, necessary for functioning of muscles and nerves. The kidneys maintain the proper balance of this and water in the blood. Potassium (K+) and Sodium (Na+) are examples of this
What is electrolyte
500
substance containing nitrogen and excreted in urine
What is nitrogenous waste
500
nitrogenous waste excreted in urine
What is creatinine
