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
