1. Physiology of the Circulatory System 2 components: Systemic & Pulmonary Circulation A video to watch: https://www.youtube.com/watch?v=NJzJKvkWWDc

2. Pulmonary path to the lungs Releases CO 2 in blood  blood receives oxygen 2) Goes to pulmonary arteries 3) Smaller arteries 4) Arterioles 5) Pulmonary capillaries that surround alveolus 1) Start in right ventricle

3. 10)left atrium 9)Pulmonary veins Pulmonary path from the lungs 6)capillaries 7)venules 8)veins

4. Red blood cells exchange gases in the lungs Gas Exchange Release Co 2 and receive O 2

5. 2 Systemic Pathway oxygen to cells  cells release waste 9)right atrium 8)vena cava 1)left ventricle 2) aorta 7)veins 3)Smaller arteries 4)arterioles 6)venules 5)capillaries

6. capillaries Releases O 2  receives CO 2 cells of organs Gas Exchange surrounding

7. Blood Circulation 1)Atria empties its blood into the ventricles 2)Ventricles push blood towards the body & lungs

8. - blood pressure is at its minimum: diastolic Blood Pressure - Pressure where blood is pushed against arteries pressure - blood pressure maximum: ventricle systole High Blood Pressure Abnormal increase of pressure in the artery walls - Could tear the heart and damage arteries - Could be temporary causes: diet, stress, tobacco and alcohol

9. Coronary Bypass Vein is removed from another part of the body. Result: blood bypasses around blocked artery

10. Arterial Endoprosthesis Small spring inserted in the arteries for blood circulation Angioplasty: introduction through the groin or arm  smaller than coronary bypass
