| ventricles | the two lower chambers of the heart, and they pump blood out to the lungs and to the body |
| arteries | blood vessels that carry blood away from the heart |
| aorta | it is the largest artery in the body: it carries oxygenated blood throughout the entire body |
| veins | blood vessels that carry blood back to the heart |
| vena cava | bring deoxygenated blood from the body to the right atrium |
| capillaries | the bodies smallest blood vessels that exchange nourishment and fluids throughout the body (ex oxygen and nutrients) |
| spleen | Helps recycles blood cells, replacing bad ones with good ones to protect the bodies immune system |
| thymus | Produces T cells that help the bodies immune system-located in front of the heart |
| thyroid | regulates the body's metabolism and calcium balance |
| cerebrum | the most anterior part of the brain and it controls all voluntary actions |
| spinal cord | a major part of the central nervous system which conducts sensory and motor nerve impulses to and from the brain |
