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 582-589 on P. 589 Q’s 1-5

3. OUTLINE FOR CIRCULATORY SYSTEM I.Blood Vessels a.Arteries b.Veins c.Capillaries d.Blood pressure II.Heart a.Chambers b.Associated blood vessels c.Direction of blood flow

4. III.Blood a.Red Blood Cells (RBC’s) b.White Blood Cells (WBC’s) c.Platelets d.Plasma IV.Disorders of the Circulatory System V.Types of Circulation a.Pulmonary Circulation b.Systemic Circulation

12. Topic: Circulatory System AIM: How do the structures of the heart work to pump blood into our arteries? HW: Worksheet – Chapter 9 Review 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 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.

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.
