Topic: Circulatory System

AIM: How do the structures of the heart work to pump blood into our arteries?

HW: Worksheet – Chapter 9 ReviewReminder: 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 IVC2. 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 occur4. 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.

1. What is Pulmonary and Systemic Circulation?

2. How does the Circulatory System help to accomplish Cellular Respiration?

3. How does the circulatory system help maintain homeostasis?

4. Explain the purpose of valves.
