5 Quarts
The amount of blood that the average heart can pump at REST in one minute
40 Quarts

Lungs
Where blood must travel to get rid of carbon dioxide and pick up oxygen
Aorta
Largest artery in the body that delivers oxygenated blood out to the body
Superior Vena Cava & Inferior Vena Cava
Two special veins that bring deoxygenated blood into the heart from the upper and lower body
Arteries
Type of blood vessel that is muscular and flexible
Veins
Type of blood vessel with thin walls
Red Blood Cells
Make up 44% of blood, produced in bone marrow, contain hemoglobin - a protein that carries oxygen
White Blood Cells
Make up less than 1% of blood, helps to fight infections/bacteria
Plasma
Makes up 55% of blood, liquid portion, mostly water but contains electrolytes, vitamins, platelets, nutrients, hormones, etc.
Platelets
Clotting factors that help seal a wound/prevent blood loss
Red
The color of blood, whether it is inside or outside the body, whether it is oxygenated or deoxygenated
A, B, AB, O
The 4 main blood types found in humans
Tricuspid Valve
The valve between the right atrium and right ventricle
Pulmonary Valve
The valve between the right ventricle and pulmonary artery
Mitral Valve
The valve between the left atrium and left ventricle
Aortic Valve
The valve between the left ventricle and aorta
