-> blood AWAY from ♡
veins
-> blood TO the ♡
pulmonary circuit
- not O2 blood from R ventricle to lungs
- blood gets oxygenated
- O2 blood to L atrium
- HERE, arteries dont carry O2 blood
-smaller loop
systemic circuit
-O2 blood L ventricle to capillaries in body
- nonO2 blood to R atrium
white blood cells
attack invaders as viruses and bacteria
for imunity
red blood cells
- p. hemoglobin, Fe carries oxygen + waste
no nucleus
dont reporduce
120 days
45%
platelets
help with blood clotting

antibodies
proteins in plasma.
recognize foreign substances and alert the immune system

- on kidneys
- produce hormones (cortisol, adrenaline)
nephron
basic function unit of kidneys
filtrate the blood
ensures the formation of urine
glomerulus
filters the blood
tubule
returns needed substances to blood and removes waste
proximal convoluted tubule
reabsorption and secretion
distal convoluted tubule
between the loop of Henle and collecting duct
loop of Henle
reabsorb water and sodium chloride from the filtrate
