Study Notes
Circulatory System II
- Venules have the lowest pressure
- Capillaries facilitate gas exchange
Great Vessels
- The aorta emerges from the left ventricle.
- It initially ascends, then curves downward.
- The aorta branches into ascending, aortic arch, and descending portions.
- The descending aorta divides into thoracic and abdominal portions.
- Location depends on the body region.
Aortic Arch
- The aortic arch curves to the left like an inverted U.
- Superior to the heart.
- It gives off three major arteries:
- Brachiocephalic trunk
- Left common carotid artery
- Left subclavian artery
Arteries of Upper Limb
- Subclavian artery continues as axillary artery, then brachial artery.
- Brachial artery divides into ulnar and radial arteries.
- Radial and ulnar arteries are the two terminal branches of the brachial artery.
Arteries of Lower Limb
- When the femoral artery reaches the back of the knee, it becomes the popliteal artery.
- The popliteal artery branches into anterior and posterior arteries.
Veins of the Upper Limb
- Superficial and deep veins.
- Deep veins are close to arteries and share the same name.
- Radial and ulnar veins unite to form the brachial vein.
- The brachial vein becomes the axillary vein after passing the pectoralis major muscle.
- The axillary vein becomes the subclavian vein after passing under the clavicle.
Veins of the Lower Limb
- Arcus venosus dorsalis pedis
- Great saphenous vein
- Opens into femoral vein
- Small saphenous vein
- Empties into popliteal vein
Deep Veins of Lower Limb
- Anterior and posterior tibial veins and fibular veins drain into the popliteal vein.
- The popliteal vein continues as the femoral vein in the thigh region.
Intravenous Injection
- Techniques for intravenous injection include intradermal, subcutaneous, and intravenous.
- Puncture site preparation is crucial.
- Factors like the angle of injection and positioning need to be considered.
