2. Big Idea-Why it’s Important?
Circulatory System
Big Idea-Why it’s Important?
Your circulatory system provides each cell in your body with a continuous supply of oxygen and nutrients and takes away carbon dioxides and other wastes.
DID YOU KNOW-Every cell is within 0.10 to 0.15 mm from a capillary.

3. The Heart Made of cardiac muscle tissue
Heart has 4 chambers-to keep the oxygen-rich blood from mixing with oxygen-poor blood.
2 upper- left & right atriums
2 lower- left & right Ventricles

4. Pumped by Heart Pulmonary Systemic circulation circulation
Oxygen provided to cells
Wastes removed from cells
Pulmonary
circulation
Wastes removed in lungs
From heart to lungs and back to heart
Oxygen added
From heart to body and back to heart

5. Artery Vein Capillary Blood Vessels

(to the capillaries)

6. Artery Vein Capillary Blood Vessels
Blood vessel that carries blood away from the heart
(to the capillaries)
Blood vessel that carries blood back to the heart
(from the capillaries)

7. Artery Vein Capillary Blood Vessels
Blood vessel that carries blood away from the heart
(to the capillaries)
Blood vessel that carries blood back to the heart
(from the capillaries)
Microscopic blood vessels that connects arteries and veins
Nutrients, oxygen, wastes and CO2 diffuse w/cells

8. Summarize the exchange that occurs between a systemic capillary and the tissue cells it serves.

9. Summarize the exchange that occurs between a systemic capillary and the tissue cells it serves.
The blood flowing through the capillaries delivers nutrients and oxygen to the tissue cells.
These are exchanged for carbon dioxide and wastes which are removed from the tissue cells.

11. What is blood pressure 120/80 ?
Diastolic
Systolic
Blood pressure is the force of blood on the walls of vessels.
First number measures when ventricles contract and blood is pushed out of the heart.
Second number measures pressure when ventricles fill with blood again.
