Biology II - Cardiovascular System: Overview

Biology II

what does cardiovascular mean

heart vessels

what is the purpose of the cardiovascular system

to transport blood to and from every living cell in the body

what does blood deliver to each cell

oxygen, nutrients, water, hormones, white blood cells

what does blood remove from each cell

waste (CO2)

what are the three types of the cardiovascular system

heart, blood, and blood vessel

what is the heart

pump made of cardiac muscle

what does the heart pump blood to

to body cells and the lungs

how many times does the heart beat per minute

76

how many chambers is the heart made of

4

what is blood made of

cells and plasma (liquid matrix)

what is the function of blood

red blood cells and plasma: transfer things

white blood cells: fight infection

platelets: clot blood

how many different types of blood vessels are there and name them

3 types: arteries, capillaries, and veins

what do the arteries do

carry oxygenated blood away from the heart to the body cells

what are the capillaries

tiny blood vessels that connect arteries and veins at the body cells

what do the veins do

carry deoxygenated blood back to the heart from the body cells
