Study Notes
Heart Anatomy Overview
- Apex: The heart's blunt point oriented towards the left, crucial for identifying its position in the thoracic cavity.
Chambers of the Heart
- Right Atrium: Superior chamber on the right side, responsible for receiving systemic venous blood returning from the body.
- Right Ventricle: Inferior chamber on the right side, receives deoxygenated blood from the right atrium and pumps it into the pulmonary trunk.
- Left Atrium: Superior chamber on the left side, its main function is to receive oxygenated blood from the pulmonary veins.
- Left Ventricle: Inferior chamber on the left side, pumps oxygenated blood received from the left atrium into the aorta for distribution to the body.
Major Blood Vessels
- Pulmonary Trunk: Collects deoxygenated blood from the right ventricle and splits into pulmonary arteries heading towards the lungs.
- Right Pulmonary Artery: A branch of the pulmonary trunk, it carries deoxygenated blood specifically to the right lung for oxygenation.
- Left Pulmonary Artery: Another branch of the pulmonary trunk, it transports deoxygenated blood to the left lung for oxygenation.
