The Circulatory System
20
heart: its function is to pump blood around the body
muscle: the heart is the largest ................................ in the human body
artery: large blood vessel that takes oxgenated and nutrient rich blood from the heart to the body
vein: large blood vessels that bring deoxygenated blood back to the heart
venous valve: directs blood flow along the vein to the heart
capillary: smallest blood vessels that exchanges the oxygen, nutrients and waste
arteriole: small artery
venule: small vein
white: blood cells that fight infection
red: blood cells that carry iron and oxygen, gives blood its colour
platelets: clotting agent in blood that stops bleeding
plasma: yellow fluid of blood, carries nutrients
trachea: pipe where air is taken to and from the lungs
bronchus: smaller tubes in the lungs that carry air
bronchiole: smaller tubes than bronchus that takes oxygen/carbon dioxide to and from the alveoli
alveoli: tiny air sacs
pulmonary artery: large blood vessel that takes deoxygenated blood from the heart to the lungs
pulmonary vein: large blood vessel that takes oxygenated blood back to the heart
oxygenated: filled with oxygen
deoxygenated: depleted of oxygen
