blood circulation
circulation is the constant +movents of the blood >the blood vessels around the body + the heart involves two stages
pulmonary circulation
is the movent of the blood+ between the heart and the lungs +1. blood contained in the right atrium+ passesto the right ventricle +2. the right ventricle contracts +and pumps blood <the pulmonary arteries +3. blood circulates >the pulmonary arteries insidev the lungs+to reach the capillaries +4. in the capillares gas enchanges ocuur the blood>oygen>carbon dioxide+5. the returning blood passes from the capillares to the pulmonary veins
systemic circulatin
is the movement of blood +between the heart and rest of the body+1. oxygen ated blood enters the left atrium and passes to the left ventricle+2. the left ventricle contracs and pumps blood > the aorta+3. the aorta branches into smallersarteries to+reach the capillaries in the differents organs +4. in the small intestine., blood picks up nutriens >absorption +5. in the capillaries ,blood , oxygen´carbon dioxide +6. in the kidneys ´blood +filters to releases waste substance +7. finally, blood returns to the right atrium+ of the heart>the vena cava
blood is made of plasma +,which is the liquid part+blood cells

capillaries
the heart
the heart is a organs+ made up of muscle+these muscle are working all the time + pump blood ariund the body +the heart is diviide+into two halves
