• The circulatory system is responsible for the flow of blood, nutrients, oxygen, and other gases to and from the cells.

• pumps blood through the network of arteries and veins

• The arteries and veins are responsible for carrying the blood to and from the heart and the rest of the body

• CARDIAC = HEART

• CARDIOVASCULAR SYSTEM

• The heart is the main organ of the circulatory system

• tube-like structures that carry blood throughout the body

• There are 3 blood vessels: arteries, veins, and capillaries

• arteries carry oxygen-rich blood AWAY from the heart

• the red blood you see represents oxygen-rich blood

• veins carry blood back TO the heart to get oxygen

• carries oxygen-poor blood (the blue you see)

• Capillaries are the SMALLEST blood vessels, they are very tiny as you see in the picture.

• they EXCHANGE MATERIALS just like the alveoli

• oxygen and carbon dioxide is exchanged here

I hope so :)
