pressure in arteries
the force of blood pushing against artery walls as the heart pumps it to the body
pulmonary valve
a one way , three leaflet door located in the middle of the right ventricle and the pulmonary artery
blood pressure
the force of blood pushing against artery walls as the heart pumps it around the body
biscupid valve
a cognenitial heart defect where the aortic valve has two leaflets instead of 3
function of the system
transport nutrients, hormones, throughout the body and removes waste products like carbon and metabolic waste
pressure in veins
returns blood to the heart
capillaries
microscopic vessels that form a dense network with myocardium branching from coronary arteries to deliver oxygen and nutrients while removing metabolic waste
aortic valve
a critical , three leaftlet structure located between the left ventricle and aorta (main artery)
triscupid valve
a one way door between the right atrium and right ventricle
venule
tiny blood vessels that collet oxygen poor blood from capillaries
right ventricle
the lower right chamber of the heart that pumps deoxygentated blood to the lungs through pulmonary artery for oxygenation
mitral valve
separates the left atrium from the left ventricle
flow of blood
one way circuit- alternatates oxygenated (L) and deoxygenated (R) blood
plasma
carries nutrients and waste through the heart in a two part loop
double circulation
blood passes through the heart twice in one complete cycle
left ventricle
the thickest and largest chamber of the heart , pumps through the aortic valves to the entire body
phagocytosis
the process of a cell eating by sorrounding large solid particles such as bacteria or cells. (basically destroys bacteria , dead cells , ect )
arteries
supply the heart muscle with oxygenated blood, orginaiting from the aorta
veins
pass nutrients throughout the blood
contents of plasma
the pale yellow liquid part of blood that carries blood cells nutrients and waste throughout the body.
what does blood mainly consist
plasma, platelets, red blood cells, white blood cells
red blood cells purpose
carry oxygen from the lungs to our bodys tissue
white blood cells
fight off infections
