PreDissection Drawing Activity Pathway of Blood Through Heart

Pre-Dissection Drawing Activity Pathway of Blood Through Heart

Bell Work 2 -21 -2018 1. Name the four chambers of the heart. 2. The first heart sound (s 1) is what valves closing 3. The second heart sound (s 2) is what valves closing? 4. What structure divides the heart into right and left halves?

Standard Create an infographic to identify gross heart anatomy and physiology and related cardiac conduction and circulatory pathways.

Objective n Learn blood flow of the heart (circulatory pathway)

RIGHT SIDE OF THE HEART n DEOXYGENATED n PULMONARY BLOOD n SUPERIOR VENA CAVA n INFERIOR VENA CAVA n RIGHT ATRIUM n TRICUSPID VALVE n RIGHT VENTRICLE SEMILUNAR VALVE n PULMONARY ARTERIES n RIGHT AND LEFT LUNGS

LEFT SIDE OF THE HEART n OXYGENATED BLOOD n PULMONARY VEINS n LEFT ATRIUM n BICUSPID (MITRAL) VALVE n Left VENTRICLE n AORTIC SEMILUNAR VALVE n AORTA

PHYSIOLOGY OF THE HEART The heart is a double pump. When the heart beats… Right Heart Deoxygenated blood flows into heart from vena cava right atrium tricuspid valve right ventricle pulmonary semilunar valve pulmonary artery lungs (for oxygen) Left Heart Oxygenated blood flows from lungs via pulmonary veins left atrium mitral valve left ventricle aortic semilunar valve aorta general circulation (to deliver oxygen)

Supplies: n 3 sheets paper n pencil n 3 fine tip colored markers (blue, red, green) n Optional: highlighter (pink or orange)

The heart is a double pump. Right Heart Pump Left Heart Pump

The right heart pumps venous (deoxygenated) blood. Right Heart Pump

The left heart pumps arterial (oxygenated) blood. Left Heart Pump

Bell Work 2 -22 -18 1) When you hear lub dub, that is the heart beating. The Lub is the first sound. What valves are closing? 2) When you hear the second sound (the dub), what valves are closing? 3) Blood flows in one direction in the heart. When the blood dumps into the right atrium, what Vein did it come from?
