Study Notes
Cardiovascular System: Main Blood Vessels
- The aorta originates from the left ventricle, distributing oxygenated blood to all body parts.
- Aorta's components include ascending aorta, aortic arch, thoracic aorta, and abdominal aorta.
- Branches of the ascending aorta include the right and left coronary arteries.
- Branches of the aortic arch are the brachiocephalic trunk (dividing into right subclavian artery and right common carotid artery), left common carotid artery, and left subclavian artery.
- The abdominal aorta branches into the celiac trunk, superior mesenteric, and inferior mesenteric arteries.
- Terminal branches (of the abdominal aorta) include right and left common iliac arteries.
- The common iliac artery divides into internal and external iliac arteries.
- The external iliac artery becomes the femoral artery, supplying the lower limb.
- The internal iliac artery supplies blood to pelvic organs.
- The femoral artery branches into the popliteal artery, which further divides into the anterior and posterior tibial arteries, supplying the lower leg and foot.
- The superior vena cava drains the upper body and the inferior vena cava drains the lower body.
- Both vena cavas deliver deoxygenated blood to the right atrium.
- Pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs.
- Pulmonary veins carry oxygenated blood from the lungs to the left atrium.
- The portal vein collects nutrient-rich blood from the intestines and delivers it to the liver for processing.
- The hepatic vein carries processed blood from the liver to the inferior vena cava.
Arteries of the Head and Neck
- Four pairs of arteries supply the head and neck: common carotid arteries and three branches from each subclavian artery.
- Most parts of the head and neck receive their blood supply from the common carotid arteries.
- Common carotid arteries divide into external and internal carotid arteries.
- External carotid arteries supply most tissues outside the brain and orbit.
- Near the temporomandibular joint, external carotids split into superficial temporal and maxillary arteries.
- Internal carotid arteries supply the orbits and most of the cerebrum.
- Vertebral arteries supply the posterior brain.
- These arteries connect to form the circle of Willis, a loop of anastomoses, providing alternate blood routes to the brain.
Veins
- Venous drainage from the face is mostly superficial.
- Venous drainage from the head and neck terminates in the subclavian veins, which join the brachiocephalic veins behind the clavicle.
- Two brachiocephalic veins unite to form the superior vena cava.
- Head and neck veins are classified as external and internal groups.
- External group: internal jugular, external jugular, anterior jugular, oblique jugular, and posterior external jugular.
- Internal group: venous sinuses, emissary veins, and diploic veins.
- Deep veins of the head and neck include internal jugular veins and the right subclavian vein, which joins with the internal jugular vein to form the brachiocephalic vein.
