Pulmonary ValvePulmonary Valve
Keeps blood from flowing back Keeps blood from flowing back into the right ventricleinto the right ventricle
Bicuspid ValveBicuspid Valve
Prevents blood from flowing Prevents blood from flowing back into the left atriumback into the left atrium
Also called the Mitral valveAlso called the Mitral valve
Left AtriumLeft Atrium
Receives oxygen rich blood from Receives oxygen rich blood from the pulmonary veinsthe pulmonary veins
Pulmonary TrunkPulmonary Trunk
Transfers blood through the Transfers blood through the pulmonary arteries to the lungspulmonary arteries to the lungs
Aortic ValveAortic Valve
Prevents blood from going back Prevents blood from going back into the left ventricleinto the left ventricle
Tricuspid ValveTricuspid Valve
Prevents backflow of blood to Prevents backflow of blood to the right atriumthe right atrium

Blood from the SVC & IVC is Blood from the SVC & IVC is released into the right atriumreleased into the right atrium
Path of Blood FlowPath of Blood Flow Place the following items in the correct sequence: body tissue, aorta,
bicuspid valve, left atrium, lungs, pulmonary trunk, pulmonary arteries, left ventricle, pulmonary veins, right atrium, right ventricle, tricuspid valve, aortic valve, pulmonary valve., superior vena cava
Oxygen poor blood is collected from the inferior and ___________ _______ ________. It is released into the _________ _______ where it moves through the _________ valve into the ________ __________. When the right ventricle contracts, blood is forced through the _________ valve into the ____________ _______ which splits into the left & right pulmonary __________. Blood is taken via the arteries to the _____ where oxygen & carbon dioxide diffuse through the simple squamous tissue. Oxygen-rich blood then returns to the heart via the ___________ ________ which empty into the _________ ________. Once the atrium contracts, the blood passes through the __________ ________ into the _________ _________. Once the ventricle contracts blood is forced through the _________ valve and out of the _________ to travel to the _______ ________ .
