| What is the function of the circulatory system | to deliver nutrients to body and expel waste |
| 3 Main parts of Circulatory System | Heart, Blood Vessels, Blood |
| What are the three types of blood vessels | Arteries, Veins and Capillaries |
| Arteries | blood FROM the heart |
| Veins | blood TO the heart |
| Capillaries | nutrients and oxygen to tissue and absorb CO2 |
| Six Functions of Blood | (1) Collect O2 (2) Collect Nutrients (3) Collect Waste Products (4) Helps regulate internal environment (5) Fight Infection (6) Repairs damages blood vessels |
| Where does the REAL WORK of the circulatory system take place? | Capillaries |
| Four main components of blood: | (1) Plasma (2) Red Blood Cells (3) White Blood Cells (4) Platelets |
| Plasma | water, dissolved gases, salts, nutrients, enzymes, hormones, waste products and proteins |
| RBC | transports O2 |
| WBC | fight against infection |
| Platelets | helps with clotting |
| How does blood flow through the body and heart and lungs | L--RA--RV--B--LA--RV |
| Septum | Separates both sides of the heart so that O2 and non-O2 don't mix |
| Atrium | recieves blood |
| Ventricle | Pumps blood to body or lungs |
| Pulmonary Circulation | Pumpin blood to the lungs (Right Side) |
| Systemic Circulation | pumping blood to the body (Left Side) |
| Valve | flap of tissue keeping blood flowing one way |
