Chapter 26- Urinary System Flashcards
function of kidneys
making urine
function of ureters
conducting urine
function of bladder
storing urine
function of urethra
leads urine outside of the body
functions of the urinary system
excreting waste products, regulation of blood volume, composition, BP, blood pH, assisting hormone and nutrient metabolism
renal fascia
dense irregular CT
adipose capsule
a mass of fatty tissue
renal capsule
transparent fibrous membrane
renal hilus
where ureters and blood vessels enter and exit the kidney
nephrons
functional unit of kidneys
functions of DCT
tubular excretion – keep or get rid of hydrogen ions to balance pH
JGA
juxtaglomerular apparatus– helps to regulate blood pressure, secrets renin –> angiotensinogen –> angiotensin to increase BP
3 steps of urine formation
- pressure filtration in glomerulus
- selective reabsorption in PCT
- tubular excretion in DCT
ADH
antidiuretic hormone secreted in pituitary gland
aldosterone
secreted in adrenal cortex, receptors in DCT
