|
large artery that carries blood away from the heart to the rest of the body
|
|
Aortic valve
|
heart valve that opens from the left ventricle to the aorta
|
|
artery
|
blood vessel that carries blood away from the heart to the tissues
|
|
atrium (auricle)
|
left or right upper chamber of the heart
|
|
blood vessel
|
tube such as an artery or vein that carried blood through the body
|
|
blood pressure
|
the amount of force that blood exerts upon the walls of the blood vessel
|
|
capillary
|
microscopic blood vessel that carries blood from arteries to veins and supplies individual cells
|
|
circulatory system
|
transportation system carrying food, oxygen, and cell waste
|
|
coronary arteries/veins
|
actual blood vessels on the heart muscle that bring food and oxygen and remove wastes
|
|
diastolic pressure
|
pressure on the arteries when either the left atrium and the left ventricle are relaxed
|
|
heart
|
muscular organ of the circulatory system that pumps blood throughout the body
|
|
heart valve
|
special structures of the heart that prevent blood from flowing in the wrong direction
|
|
mitral valve
|
heart valve that is located between the left atrium and the left ventricle
|
|
pericardium
|
tough sac around the heart that helps support and protect the heart
|
|
plasma
|
liquid part of the blood that is 90% water and makes up 55% of the blood
|
|
platelets
|
tiny cells in the blood that help the blood to clot (less than 1% of blood)
|
|
pulmonary artery
|
artery that takes blood away from the right ventricle of the heart to the lungs
|
|
pulmonary valve
|
heart valve that is located between the right ventricle and the pulmonary artery
|
|
pulmonary veins
|
veins that carry oxygen-rich blood from the lungs to the heart
|
|
pulse
|
the rate at which the heart beats
|
|
red blood cells
|
special blood cells that carry oxygen to the body and carry away carbon dioxide waste (44% of blood)
|
|
septum
|
dividing wall between the left and right chambers of the heart
|
|
systolic pressure
|
pressure on the arteries when the heart contracts and pumps blood
|
|
tricuspid valve
|
heart valve that is located between the right atrium and the right ventricle
|
|
vein
|
blood vessel that carries blood from the tissues towards the heart
|
|
vena cava
|
either of the body's two largest veins through which oxygen-poor blood returns to the heart (ie. superior vena cava and inferior vena cava)
|
|
ventricle
|
left or right lower chambers of the heart that receives blood from an atrium
|
|
white blood cells
|
special blood cells that destroy foreign substances in the body (less than 1% of blood)
|
|
3 parts of the circulatory system
|
blood, blood vessels, heart
|
|
Jobs of the circulatory system
|
1. transports food, waste, and oxygen
2., removes waste from cells 3. maintains body temperature 4. fights disease 5. carries chemicals |
|
Normal ranges from systolic blood pressure
|
110-140

|
what is the danger of high blood pressure & why is it a silent killer?
|
?
|
|
three types of blood vessels and their functions
|
1. arteries - take blood FROM the heart
2. Capillaries - connect arteries to veins and deliver food and oxygen and take away wastes 3. veins - carry blood back TO the heart (veins have valves) |
|
4 components of blood and their jobs
|
plasma
platelets - clotting red blood cells - carry oxygen to and carbon dioxide away white blood cells - fight disease |
|
