Aorta
Aorta
The largest artery in the body, carrying oxygenated blood from the left ventricle to the rest of the body.
Aortic Arch Branches
Aortic Arch Branches
The three major arteries that branch off from the aortic arch are the brachiocephalic trunk, left common carotid artery, and left subclavian artery.
Brachiocephalic Trunk
Brachiocephalic Trunk
The brachiocephalic trunk is a large blood vessel that branches into the right common carotid artery and the right subclavian artery.

Study Notes
Circulatory System II
- Venules have the lowest pressure in the circulatory system.
- Capillaries facilitate gas exchange.
Great Vessels
- The aorta originates from the left ventricle.
- Initially ascending, it curves downwards.
- Divided into ascending, arch, and descending segments.
- The descending aorta further divides into thoracic and abdominal sections based on location.
- Branches of the aorta supply oxygenated blood to various tissues.
Aortic Arch Branches
- The aortic arch gives rise to three major arteries:
- Brachiocephalic trunk
- Left common carotid artery
- Left subclavian artery
- These vessels deliver oxygenated blood to the upper body.
Arteries of the Upper Limb
- The subclavian artery continues as the axillary artery. Then it becomes the brachial artery.
- The brachial artery divides into the radial and ulnar arteries.
Arterial Branches
- The brachial arteries terminate into radial and ulnar arteries.
Arteries in the Lower Limb
- The femoral artery transitions to the popliteal artery.
- The popliteal artery branches into posterior and anterior arteries for the knee and lower leg.
Pulse Measurements
- Key pulse points include femoral, popliteal, posterior tibial, and dorsalis pedis.
- Pulse measurements are important indicators of circulatory health.
Venous System: Upper Limb
- The superior vena cava drains blood from the upper body.
- The superior vena cava is formed by the fusion of the right and left brachiocephalic veins.
- Subclavian and internal jugular veins unite to create brachiocephalic veins.
Venous System: Lower Limb
- The inferior vena cava receives deoxygenated blood from the lower body.
- The inferior vena cava is formed by the union of the right and left common iliac veins.
- The common iliac veins are the union of the external and internal iliac veins.
Intravenous Injection
- Intravenous injections are performed by inserting a needle into a vein for medication delivery.
- Considerations include appropriate vein selection, needle angle (e.g., 15-25 degrees), and puncture site coverage.
