Circulatory System
• Cardiovascular System– Heart– Blood Vessels
• Arteries• Veins
• Lymphatic System
04/21/23 4
Anatomy• Arteries
– Carry oxygenated blood
– Take blood away from heart to the body
• Veins– Carry deoxygenated blood
– Bring blood back to the heart from the capillary beds
• Capillaries– Connect arteries and veins
04/21/23 6
Anatomy
• Lymphatic System– Lymph – fluid collected– Lymph nodes – small collections of lymphatic
tissue through which lymph fluid is filtered– Lymphocytes – cells of the immune system
04/21/23 7
Electrical Conduction in the Heart
– Conduction begins in sinoatrial node of right atrium• Nature’s pacemaker• Firing causes contraction of muscle
– Moves to atrioventricular node• Then to Bundle of His along septum• Then to Purkinje fibers along the surface of
ventricles
Circulations
• Pulmonary Circulation– Pushes deoxygenated blood into the lungs– Carbon dioxide removed and oxygen added– Blood flows to the left atrium
• Systemic Circulation– Blood flows from left atrium into the left
ventricle– Pumped to the body to deliver oxygen and
remove carbon dioxide04/21/23 9
