Exchanges nutrients with cells. | Capillaries |
Gets blood from all body tissues. -Oxygen poor- | Veins |
Brings oxygen to all cells. Important in immune and endocrine system. | Blood |
relatively pure, into the carotid arteries taking blood to the head (and brain) | Oxygenated Blood |
Cardiology Blood with a low O2 saturation relative to blood leaving the lungs | Deoxygenated Blood |

Prevents friction when heart beats | Pericardium |
Outter layer of heart, inner layer of pericardium sac | Epicardial |
Consists of cardiac muscle, middle and thickest layer of heart | Myocardium |
