Anatomy Flashcards
A muscular pump that forces blood around the body
Heart
Vessels that carry blood away from the heart.
Arteries
Vessels that bring blood back to the heart.
Veins
Tiny vessels that branch off from arteries to deliver blood toall body.
Capillaries
2 blood circulatory systems in the body.
systemic circulatory system.
pulmonary circulatory system.
3 vessels
Arteries, Veins, capillaries
main blood circulatory system that transports blood to the organs, tissues, and cells throughout the body.
Systemic circulatory system
This circulatory system moves blood between the heart and lungs. It is where oxygen enters the blood and carbon dioxide leaves the blood.
Pulmonary circulatory system
The heart consists of four distinct chambers:
Right and left atria ( Upper )
Right and left ventricle ( lower )
separates the atria and ventricles.
wall or “septum”
control the flow of blood within the different chambers.
Valves
Thecardiac cycle consists of two phases.
Diastole and systole
1st phase , which the ventricles fill with blood
Diastole
2nd phase, which the ventricles contract and eject blood
Systole e

Pericardium
– a double serous membrane

Next to the heart
Visceral pericardium
Outside layer
Parietal pericardium
3 layers of heart
Epicardium
Myocardium
Endocardium
Outer layer of heart that contains blood vessels
Epicardium
Middle layer of heart that conposed of cardiac muscle or contractile tissues
Myocardium
Innermost kayer of heart that compose of Valves
Endocardium
– receiving chambers
Atria
– discharging chambers
Ventricles
