1. The Circulatory System
Aim: How does the circulatory system help to maintain homeostasis?
Do Now: Open Workbooks to Page 11 and read section on Circulatory System. Complete handoud reading and questions as well.Homework: Text Rd on P Q’s 1-5

Pulmonary Circulation
Systemic Circulation

12. Topic: Circulatory System
AIM: How do the structures of the heart work to pump blood into our arteries?
HW: CASTLE LEARNING QUIZ DUE THURSDAY
Reminder: Test on Friday

14. 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

15. The Path and Flow of Blood Through the Heart
DeO2 Blood from body is returned to the RA via the SVC and IVC
Blood passes through a valve into the RV and is pumped into the Pulmonary Arteries. (only arteries that carry DeO2 Blood)
PA’s lead blood to the lungs where diffusion of CO2 and O2 occur
Blood is returned from the lungs through the Pulmonary Veins (only veins that carry O2 Blood) into the LA.
Blood passes through a valve into the LV and is pumped into the AORTA to go to the body.

16. 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.
