the heart work to pump blood
into our arteries?
HW: Worksheet – Chapter 9
Review
Reminder: Test on Friday
The Heart:
Has 4 Chambers
•2 Atria: Upper Chambers : Receive Blood either from body
or lungs
•2 Ventricles: Lower Chambers : Pump Blood either to lungs
or body
•On Diagrams the left side is labeled right
the right side is labeled left
•Made up of CARDIAC Muscle
•Pericardium is the membrane that surrounds the heart
The Path and Flow of Blood Through the Heart
1. DeO2 Blood from body is returned to the RA via the SVC and IVC
2. Blood passes through a valve into the RV and is pumped into the
Pulmonary Arteries. (only arteries that carry DeO2 Blood)
3. PA’s lead blood to the lungs where diffusion of CO2 and O2 occur
4. Blood is returned from the lungs through the Pulmonary Veins
(only veins that carry O2 Blood) into the LA.
5. Blood passes through a valve into the LV and is pumped into the
AORTA to go to the body.
