To transport materials around the body

To transport materials around the body

The function of the circulatory system

Veins

Blood vessels that transport blood into the heart

Arteries

Blood vessels that transport blood away from the heart

Capillaries

Blood vessels that link arteries and veins, where materials are exchanged

Heart

A muscular organ that acts as a pump in the circulatory system

5 Quarts

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

40 Quarts

The amount of blood that the average heart can pump during EXTREME EXERTION in one minute

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
