1
Q

A
•Pumping action
- Pumps blood into body and lungs.
- Receives blood from the body and the lungs
- Promotes blood pressure
• Transportation
- Provides channels through which blood and lymph travel
- Provides areas ( capillaries) where to transfer gases , nutrients, fluids, electrolytes, and wastes occur.
2
Q
Be able to list the structure of the heart: chambers, valves, septum, SA nodes, AV nodes, bundle his, purkinje fibers.
A
•Chambers: 2 upper- Atria
2 lower- ventricle
•Valves:
- Tricuspid
- mitral / bicuspid
- pulmonary
-aortic
•SA node= sinoatrial node
-top of the Rt atrium
60-100bpm
•AV node= atrioventricular node
- bottom of Rt atrium
- Bundle of his- in septum
- Purkinje fibers- Through lower septum and ventricles
3
Q

A
Lt side=
Oxygenated blood
Rt side= deoxygenated blood.
4
Q
What is systole and diastole?
A
- Systole is when the ventricles force the blood into the aorta and represents the maximum amount of pressure exerted on the arteries.
- Diastole is when the ventricles relax and exert minimum amount of pressure exerted on the arteries.
5

A
- Temporal
- Carotid
- Apical
- Brachial
- Radial
- Femoral
- Popliteal
- Dorsalis pedis
- Posterior Tibial
