• Provides areas ( capillaries) where to transfer gases , nutrients, fluids, electrolytes, and wastes occur.

Question 2

Be able to list the structure of the heart: chambers, valves, septum, SA nodes, AV nodes, bundle his, purkinje fibers.

Answer 2

•Chambers: 2 upper- Atria
                    2 lower- ventricle 
•Valves: 
- Tricuspid 
- mitral / bicuspid

-aortic 

•SA node= sinoatrial node
-top of the Rt atrium
60-100bpm
