Heart:
The heart is a muscular organ with 4 cavities
is located in the mediastinum
have 1 pericardium (the coverage of the heart)
The wall of the pericardium is composed of: - myocardial
- endocardium
- pericardium

has 2 upper chambers: atria
has 2 lower chambers:

ventricles has protected atrioventricular valve orifices or cusps:
- tricuspid valve that is on the right
- bicuspid valve that

left out of the right ventricle pulmonary artery.
The aorta leaves the left ventricle
The superior vena cava enters the right atrium
The pulmonary veins enter the left atrium

Arteries: blood vessels that carry oxygenated blood from the heart, pulmonary artery except
Veins: Blood vessels that carry deoxygenated to elcorazon, except the pulmonary vein
Hair: small vessels that carry blood from small arteries ( arterioles) to small veins (venules)
Circulation: blood flow through the closed circuit of vessels
general circulation: blood flows from the left ventricle to the aortay from there to the rest of the arteries, arterioles, capillaries, venules and veins , to return in the right atrium
Pulmonary Circulation: The blood goes from the right ventricle to the pulmonary artery, then passes through the arterioles, capillaries and venules of the lung. Then dump the contents of the pulmonary veins ending in the left atrium.
