1 It is the pump that circulates blood throughout the body. More than 50% Americans carry genes that cause increased heart attack or stroke risk. Heart disease is the leading cause of death for women Remember the structures of the circulatory system1

2 2 The heart is a double pump. Chambers-4 Valves-4 Double pump because it pumps blood in and out of both sides of the heart. Electrical Conduction system that causes it to beat

3 2.01 Remember the structures of the circulatory system3 Myocardium Endocardium Pericardium Septum

4 2.01 Remember the structures of the circulatory system4 Right atrium Right ventricle Left atrium Left ventricle

5 2.01 Remember the structures of the circulatory system5 Right atrium Tricuspid valve Bicuspid (mitral) valve Left atrium Pulmonary semilunar valve Aortic semilunar valve Apex Septum Right ventricle Left ventricle

6 2.01 Remember the structures of the circulatory system6 Superior vena cava Inferior vena cava Right atrium Tricuspid valve Bicuspid (mitral) valve Left atrium Aorta Pulmonary artery Pulmonary vein Pulmonary semilunar valve Aortic semilunar valve Apex Septum Right ventricle Left ventricle

7 Right side Superior vena cava Inferior vena cava Right atrium Tricuspid valve Right Ventricle Pulmonary valve Pulmonary artery Lungs CO2 and O2 exchange Left Side Pulmonary vein Left atrium Bicuspid valve Left ventricle Aortic valve Aorta Body 2.01 Remember the structures of the circulatory system7

8 8 Refer to your textbook to identify the structures of the heart’s conduction system in the correct sequence for the heart to beat.

9  ARTERIES  Arterial blood  Oxygen rich  Bright red, spurts 2.01 Remember the structures of the circulatory system9

10  ARTERIES  Carry oxygenated blood away from the heart to the capillaries  Elastic, muscular and thick-walled  Transport blood under very high pressure  Arteries > arterioles > capillaries 2.01 Remember the structures of the circulatory system10

11  VEINS  Carry deoxygentated blood away from the capillaries to the heart.  Blood is pumped thru the heart under low pressure and walls are thin thus veins can collapse easily.  Have valves that allow blood to only flow in one direction- toward the heart. This prevents backflow of blood toward capillaries Remember the structures of the circulatory system11

12 2.01 Remember the structures of the circulatory system12 See handout List major artieries and veins from both Cardiopulmo n-ary and Systemic Circulation Then take Open Book Quiz

13  Capillaries  The smallest blood vessels -1 cell thick  Connect arterioles to venules  Site of exchange Of CO2 and O2 of all cells 2.01 Remember the structures of the circulatory system13

14 Right side Superior vena cava Inferior vena cava Right atrium Tricuspid valve Right Ventricle Pulmonary valve Pulmonary artery Lungs CO2 and O2 exchange Left Side Pulmonary vein Left atrium Bicuspid valve Left ventricle Aortic valve Aorta Arteries Arterioles Capillaries Cells CO2 and O2 exchange Venules Veins 2.01 Remember the structures of the circulatory system14

15  Alternating expansion and contraction of an artery as blood flows through it Remember the structures of the circulatory system15

16 2.01 Remember the structures of the circulatory system16
