3. Atria Minimal role in pumping blood
11/16/2018
Atria
Minimal role in pumping blood
auricles - earlike hollow appendages
used as an overflow
move the blood to the ventricles

4. Ventricles Muscular chambers thick layer of myocardium
11/16/2018
Ventricles
Muscular chambers
thick layer of myocardium
left wall is thickest
trabeculae carnea connect to papillary muscles
attach to valves

5. Valves Tricuspid valve Pulmonary semilunar valve
11/16/2018
Valves
Tricuspid valve
between rt. atrium & ventricle
Pulmonary semilunar valve
between rt. ventricle & pulmonary trunk
Mitral valve (bicuspid)
between left atrium & ventricle
Aortic semilunar valve
between left ventricle & aorta

6. 11/16/2018
Blood flow
Deoxygenated blood enters the heart from the inferior vena cava, superior vena cava, and the coronary sinus
From rt atrium to rt ventricle through the tricuspid valve
From rt ventricle to pulmonary trunk through the pulmonary semilunar valve

7. 11/16/2018
Blood flow
From the pulmonary trunk to the rt and left pulmonary arteries to the lungs
Oxygenated blood returns from the lungs in the pulmonary veins to the left atrium
From the left atrium to the left ventricle through the bicuspid valve

8. 11/16/2018
Blood flow
From the left ventricle to the aorta through the aortic semilunar valve
From the aorta to the rest of the body
Back to the right atrium through the inferior vena cava, superior vena cava, and coronary sinus

Coloring
Handout - Human Heart - Front Removed / p. 166
Choose dark colors for chambers and vessels carrying deoxygenated blood
Choose bright colors for oxygenated blood
Color both sides with corresponding colors (for example, rt atrium dark blue in all three)

13. List of things to color Right atrium left atrium right ventricle

14. Fetal Heart Foramen ovale Ductus arteriosus
11/16/2018
Fetal Heart
Foramen ovale
hole between the right and left atrium
Ductus arteriosus
blood vessel between the pulmonary trunk and aorta
Both of the above close when the first breath is taken
