Pulmonary Valve

Keeps blood from flowing back into the right
ventricle
Bicuspid Valve


Prevents blood from flowing back into the left
atrium
Also called the Mitral valve
Left Atrium

Receives oxygen rich blood from the pulmonary
veins
Pulmonary Trunk

Transfers blood through the pulmonary arteries
to the lungs
Aortic Valve

Prevents blood from going back into the left
ventricle
Tricuspid Valve


Prevents backflow of blood to the right atrium
3 cusps
Aorta


Blood flows from the aorta throughout the
entire body
Largest vessel in the body
Left Ventricle


Pumping chamber which forces blood through
the aortic valve
More muscular than the right ventricle
Right Atrium


Collecting chamber
Blood is forced to the right ventricle
Interventricular Septum

Separates the pumping chambers of the heart
Superior Vena Cava

Blood from the SVC & IVC is released into the
right atrium
Path 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.
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 _______ ________ .
Right Ventricle

Receives blood from the superior and inferior
vena cava
