Excretory and Urinary System

kidney

Filters waste from the blood like urea, water, salt and proteins.

nephron

the functional unit of the kidney where filtration, reabsorption, and secretion take place

glomerulus

A ball of capillaries surrounded by Bowman's capsule in the nephron and serving as the site of filtration in the vertebrate kidney.

Bowman's capsule

cup-shaped structure of the nephron of a kidney which encloses the glomerulus and which filtration takes place.

Renal tubule

microscopic tube in the kidney where urine is formed after filtration

loop of Henle

section of the nephron tubule that conserves water and minimizes the volume of urine

filtration

movement of water and solutes from plasma into Bowmans capsule
requires high pressure
location- glomerulus

reabsorption

process whereby renal tubules return materials necessary to the body back into the bloodstream

secretion

a process by which substances are produced and discharged from a cell, gland, or organ for a particular function in the organism or for excretion.

ureter

A duct leading from the kidney to the urinary bladder.

urethra

tube that carries urine from the bladder to the outside of the body

urinary bladder

saclike organ in which urine is stored before being excreted

urine
