  • Front
  • Back
Aorta
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
Normal ranges for diastolic blood pressure
70-90
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
know different blood types and who can give and receive each
A - has antigen A on red blood cells
B - has antigen B on red blood cells
AB - has both antigens A and B on red blood cells
O - has no antigen A or B on blood cells
Which blood type is a universal donor
O
which blood type is a universal recipient?
AB
What happens if you get the wrong blood type?
blood clotting or death
Who can recieve what blood types?
A - A or O
B - B or O
AB - A, B, AB or O
O - O
