What are blood vessels called that lead into the left atrium. What is the level of oxygen content
The left atrium is structure b pulmonary veins high oxygen pg.73
What is the structure labeled C? What is its function
C is the valve hat separates the left atrium from the left ventricle . It functions to prevent blood from flowing backward from the ventricle to the atrium pg. 73
