Study Notes
Heart Anatomy and Blood Vessels
- Erb's point is located at the third costal cartilage, 3-4 cm from the sternum.
Great Vessels of the Heart
- The main function of the great vessels of the heart is to transport oxygenated and deoxygenated blood between the heart and the rest of the body.
Aorta and Systemic Circulation
- The aorta is considered the most important artery of the systemic circulation.
- The aorta carries oxygenated blood.
- The aorta arises from the left ventricle of the heart.
Pulmonary Arteries and Veins
- The pulmonary trunk splits into right and left pulmonary arteries at the level of the fifth thoracic vertebra.
- There are two pulmonary veins for each lung, which drain into the left atrium.
Aortic Arch and Branches
- The brachiocephalic artery branches from the aortic arch to supply blood to the head, neck, and upper limbs.
Thoracic Aorta
- The thoracic aorta courses through the posterior mediastinum initially in the body.
Pulmonary Arteries Location
- The pulmonary arteries are located posterior to the right atrium.
