Funtions of the Circulatory system 

       transport oxygen, nutrients, gases, hormones, metabolites, cell wastes, blood and blood components to and from the cells of the body.  

 Function of the heart 

 

 

 

 

Provide, through contraction, the propulsive force to carry the blood into a system of vessels which circulates the blood. 

Function of the L side of the heart 

 

 

 

 

 

Recieves oxygenated blood and pumps it to the body.

Function of the R side of the heart 

Collects deoxygenated blood and supplies it to the lungs where it picks up oxygen. 

 Pericardium

Fiberous tissue sac enclosing the heart. 

Pareital Pericardium 

 

 

 

Outer layer of the paricardium 

Visceral Pericardium 

inner layer of the pericardium 

Pericardial Fluid 

 

 

Reduces friction of heart surface 

Arteries 

1. Carry Oxygenated blood away from the heart

2. Blood under highest pressure

3. Blood moves the fastest

4. Run deeper than veins 

Veins 

 

 

  

1. Carry Deoxygenated blood to the heart

2.  thinner walls than arteries

3. less pressure than arteries

4. closer to the surface 

1. Major component of the immune system

2.  returns proteins to the blood

3. lymphocyte and antibody production

4. moves fat from digestive system to circ. system
