Upper Heart Chambers (x2)
Atria (receiving chambers)
Lower Heart Chambers (x2)
Ventricles (discharging chambers)
Atria
Smaller
Ventricles
Larger
Endocardium
Inner most layer of the heart.
What are the two outer most layers of the heart?
Epicardium and Visceral Pericardium
Pericardium
Structure: A two-layered fibrous sac.
Function: Provides a thin film of pericardial fluid that creates lubrication between the heart and its enveloping pericardial sac.
Superior Vena Cava (Largest vein in the body / located on the right side)
Has poor oxygenated blood
Aorta (Largest artery in the body / located to the Left side)
Has rich oxygenated blood
Sinoatrial Node
Pacemaker for the heart.
What is the sequence of the conduction system of the heart?
1) Sinoatrial Node (SA Node / Pacemaker)
2) Atrioventricular Node (AV Node)
3) AV Bundle (Bundle of His)
4) Subendocardial Branches (Purkinje Fibers)
Arteries
Carry blood away from the heart.
Veins
Carry blood toward the heart.
Where is the Tricuspid located?
It is located to the Right of the Atrium and to the Right of the Ventricle.
What is the medical name for Heart Attack?
Myocardial Infarction
Trachea
Wind pipe, contains “C” shape rings of cartilage, and lined with respiratory mucosa.
External Repiration
Pulmonary ventilation (breathing) and pulmonary gas exchange (exchange of gases between air in the lungs and and in the blood).
Internal Repiration
Systemic gas exchange and cellular respiration (exchange of gases occurring between blood and cells of the body).
