"The Human Heart and the Cardiovascular
System" The heart and the blood vessels
work together to maintain a constant
flow of blood through the body. The heart,
located between the lungs is pear-shaped
and about the size of a fist. It
functions as a two-sided pump. The right
side pumps blood from the body to the
lungs, simultaneously, the left side pumps
blood from the lungs to the body. Each
side of the heart has two chambers, an
upper atrium and a lower ventricle. In
this learning activity, you will identify
the parts of the cardiovascular system
and examine blood flow. Let's highlight
parts of the circulatory system: Trachea,
Arch of Aorta or Aortic Arch, Lung,
Diaphragm. Let's take a closer look at
the heart. Let's highlight each term of
the human heart: Brachiocephalic Artery,
Left Common Carotid Artery, Left
Subclavian Artery, Arch of Aorta or
Aortic Arch, Left Pulmonary Artery, Left
Atrium, Left Pulmonary Veins, Great
Cardiac Vein, Branches of Left Coronary
Artery and Cardiac Vein, Left Ventricle,
Apex,
Right Ventricle, Right Coronary Artery
and Cardiac Vein, Right Atrium, Branches
of Right Pulmonary Veins, Right Pulmonary
Artery, Ascending Aorta, Superior Vena
Cava. Let's highlight parts of the heart's
interior: Aorta, Left Pulmonary Artery,
Left Pulmonary Veins, Left Atrium,
Bicuspid Valve,
Aortic Semilunar Valve, Chordae Tendineae,
Left Ventricle, Right Ventricle,
Interventricular Septum, Tricuspid Valve,
Right Atrium, Pulmonary Semilunar Valve,
Superior Vena Cava. Blood Flow
Here we view pulmonary circulation.
Now, let's view systemic circulation.
