Card Set Information
In the thoracic cavity cradled between the lungs.
the area of the chest covering the heart
The thin double walled membranous sac that surrounds the heart
The outer covering of the sac.
The inner layer of the sac. The thin tight covering over the heart surface.
The small space betweent eh two layers.
THREE LAYERS OF THE HEART
Epicardium- Outer layer
Myocardium- Middle muscular layer
Endocardium- Inner layer
Left and Right Atria-Receiving chambers
Left and Right Ventricles- The pumping chambers
Wall betweent the left and right side of the heart
Dividing the Atria
Dividing the ventricles
Superior Vena Cava
Brings blood from the head, thorax, and upper limbs.
Inferior Vena Cava
Brings blood from the trunk, abdominal viscera, and lower limbs.
A valve that deoxygenated blood passes through.
Carries oxygen poor blood to the capilary network of the lungs.
The circulation of the blood from the heart to the lungs for oxygenation and back to the heart
The veins that return oxygenated blood to the heart.
The circulation of the blood from the heart to all parts of the body and back to the heart
Supply blood to the heart muscle
Methodically generates and conducts electrical impulses throughout the myocardium, and creates the rhythmic contraction of the heart.
Large thick walled vessels that carry blood away from the heart
Thin walled arteries composed of smooth muscle carry blood to the capillaries
Allow for the exchange of material between the blood and the tissue fluid surounding the body cells
The smallest veins which collect deoxygenated blood from the cells for transport back to the heart
One cardiac cycle is equivalent to one complete heart beat
Phase of the cardiac cycle forcing blood out of the heart
Phase of the cardiac cycle allowing the heart to refill with blood
Carries blood back to the lungs for oxygenation
The pressure exerted by the blood on the walls of the arteries
Any deviation from the normal pattern of the heartbeat
