| Question | Answer |
| Circulatory System | Transports fluids thru body (cardiovascular + lymphatic) |
| Cardiovascular System | heart and blood vessels for blood transportation |
| What are the 2 types of circulations of the heart? | The pulmonary and systemic circulations |
| Pulmonary Circulation | LOW oxygen blood from the right ventricle through the lungs then HIGH oxygen blood into the left atrium |
| Systemic Circulation | HIGH oxygen blood in left ventricle thru the body via systemic ARTERIES. exchange O2 for CO2 in capillaries LOW O2 blood back to heart in right atrium via systemic VEINS |
| What are the 3 types of blood vessels? | Arteries, Veins, and Capillaries |
| Arterioles | final distributing vessels deliver HIGH O2 blood to capillaries |
| Capillaries | junction for exchange between arteries and veins |
| Capillary Beds | where the interchange of O2, nutrients, waste products, and other with the extracellular fluid occurs |
| Venules | thin walled vessel where blood from the capillary bed passes into and drain into small veins then medium then large veins |
| Largest Veins | Superior and Inferior Vena Cava return LOW O2 blood to heart |
| What are the pressures in the arteries and veins? | Low pressure in the veins, high pressure in the arteries. |
| What lines all of the blood vessels? | Endothelial cells |
| Anastomoses | communications between multiple branches of an artery provides many ways for blood to flow in case of obstruction |
| Is there more veins or arteries in the body? | More veins. 1 artery for every 2 veins usually |
| Vascular Sheath | fascial tissue enclosing accompanying veins with one artery helps with arteriovenous pumping |
| Portal Venous System | blood passing through 2 capillary beds before returning to the heart Ex. Hepatic Portal System |
