Major Blood Vessels
Exits from the right ventricle to the lungs, carries deoxygenated blood to the lungs for oxygenation.
Pulmonary Arteries
Located between the right atrium and right ventricle
Tricuspid Valve
This chamber is located in the upper right side of the heart and receives deoxygenated blood form the body via the superior and inferior vena cava and sends it to the right ventricle.
Right Atrium
Located in the right atrium and is the natural pacemaker, initiates heartbeat.
Sinoatrial (SA) Node
These blood vessels exit from the right ventricle to the lungs and carry deoxygenated blood to the lungs for oxygenation
Pulmonary Arteries
This valve is located between the right ventricle and pulmonary artery.
Pulmonary Valve
This chamber is located on the lower left side of the heart and pumps oxygenated blood to the entire body through the aorta (Thickest chamber due to higher workload)
Left Ventricle
It is located between the atria and ventricles, it delays impulse before passing to ventricles, ensuring atria contract first.
Atrioventricular (AV) Node
Connects to the right atrium, it caries deoxygenated blood from the body to the heart
Superior & Inferior Vena Cava
This valve is located between the left atrium and left ventricle and prevents the backflow of blood into the left atrium when the left ventricle contracts.
Mitral (Bicuspid) Valve
This chamber is located on the lower right side of the heart and pumps deoxygenated blood to the lungs through the pulmonary artery for oxygenation.
Right Ventricle
It is located along the septum and ventricles and conducts electrical impulses to cause coordinated ventricular contractions.
Bundle of His, Bundle Branches, Purkinje Fibers
This vessel arises for the left ventricle and distributes oxygenated blood to the entire body.
Aorta
This valve is located between the left ventricle and the aorta, it prevents backflow of blood into the left ventricle after it's pumped into the aorta.
Aortic Valve
This chamber is located on the upper left side of the heart, and receives oxygenated blood from the lungs via the pulmonary veins and sends is it to the left ventricle.
Left Atrium
It is the outer protective sac surrounding the heart and protects and anchors the heart, reduces friction during heartbeat.
