Board Exams: Circulatory System (Essentials of Healthcare)
Parts of the Heart
Aorta, Left Atrium, Left Ventricle, Right Atrium, Right Ventricle, Pulmonary Vein
3 Major Blood Vessels
Arteries, Veins, Capillaries
Organs (Circulatory System)
Heart, Blood Vessels, Connective Tissues, and Muscles
Circulatory System Function
Permits blood to circulate; transports oxygen, hormones, nutrients, and blood cells
Left Ventricle
Pumps oxygenated blood out of the heart and into the aorta
Capillaries
Takes oxygenated blood towards organs, and deoxygenated blood towards the heart
Pulmonary Vein
carries blood to the Left Atrium; starts the process up again
Aorta
distributes oxygenated blood to all parts of the body; largest artery
Right Ventricle
pumps blood from pulmonary arteries into the capillaries
Right Atrium
receives deoxygenated blood and passes it to the Right Ventricle
Left Atrium
receives oxygenated blood from lungs and passes it to the Left Ventricle
Veins
takes deoxygenated blood towards the heart
Arteries
takes oxygenated blood away from the heart
