2) inferior vena cava - returns blood from the body region below the diaphragm
3) coronary sinus - collects blood draining from the myocardium
What are the 4 functions of the pericardium?
1) protects the heart
2) anchors it to the surrounding structures
3) prevents overfilling of the heart with blood
4) contains a film of serous fluid that allows the heart to glide freely as it pumps
Name 4 of the 5 factors that can regulate or change your heart rate.

What are the 3 things that connect a joint?
1) fibrous tissue - ankle
2) cartilage - ribs and sternum
3) fluid cavity - shoulders and fingers
