1. WARM UP 1. Describe how the respiratory and digestive systems both rely on blood vessels in order to carry out their functions.

2. Cardiovascular System

3. Blood Red blood cells – Hemoglobin to bind and carry O 2 and CO 2 White blood cells – Housekeeping and defense

4. Blood Platelets – Clotting Plasma – Water and antibodies

5. Circulation Internal transport by blood Exchanges at capillary beds – Lungs, small intestine, kidneys, etc.

6. Circulation Arteries branch to arterioles, then capillaries – Flow back to venules, into larger veins Two pathways – Pulmonary, with lungs – Systemic, with body

7. Major Arteries and Veins ARTERIES Coronary Pulmonary Ascending aorta Carotid Brachial Abdominal aorta Renal Iliac Femoral

8. Major Arteries and Veins VEINS Pulmonary Superior vena cava Jugular Brachiocephalic Inferior vena cava Renal Iliac Femoral

9. Heart Circuit Pulmonary flow – …..right atrium (tricuspid valve), right ventricle, pulmonary arteries, lungs, pulmonary veins…..

10. Heart Circuit Systemic flow – …..left atrium (bicuspid valve), left ventricle, aorta, body, vena cava…

11. Cardiac Contraction Controlled by SA node in right atrium – Signals AV node to contract ventricles

12. Blood Pressure Systolic (contraction) Diastolic (relaxation) Veins have valves to prevent backflow, and can stiffen to get blood back to the heart quicker

13. WRAP UP Describe the path of blood in the pulmonary circuit, starting with the right atrium. Use the terms artery, vein, oxygenated, and deoxygenated.

14. WARM UP Name 5 different arteries. Name 4 parts of the heart.

15. WRAP UP Name 3 different veins. Name 2 different blood cells. Name 1 of the measurements in a blood pressure reading.

16. WARM UP “Demand the best from yourself, because others will demand the best of you.” – Win Borden 1.What does this mean to you? 2.List some people who want to see you do your best. 3.If you put in your best effort, what do you think you could be doing in 10 years?

17. WRAP UP 1.List 5 organs/structures in each of the following organ systems: – Digestive – Respiratory – Cardiovascular 2.Compare and contrast the 3 different types of epithelial tissue.
