Explanation / Answer
1.obstruction of left subclavian artery affect mostly left upper limb.it lead to ischemia of upper limb .
artery- carry oxygenated blood ,carry bloo away from heart.
It is valveless,it has thick muscular wall.
Vein- carry deoxygenated blood,carry blood towards heart.
It has valve,it has thin muscular wall.
3 subclavian artery-axillary a rtery-brachial artery-radial and ulnar artery -superficial and deep palmer arch.
Superficial and deep venous arch-basilic and cephalic vein-median cubital vein-brachial vein-axillary vein-subclavian vein-right atrium.
4there is drop in blood pressure due to venous pooling blood to lower extremities due to gravity.
