Final answer:
Venous blood flow in the arm is from the wrist to the shoulder, which is true. The brachial vein forms from the radial and ulnar veins and leads to the axillary vein, aiding in the return of blood to the heart.
Step-by-step explanation:
Venous blood flow in the arm typically travels from the wrist towards the shoulder. This is part of the systemic circulation where blood travels back to the heart after supplying the body with oxygen and nutrients. The brachial vein is an example of a deeper vein that helps facilitate this return of blood. It is formed by the union of the radial and ulnar veins in the lower arm and leads to the axillary vein. As for the superficial venous system, the cephalic vein begins in the antebrachium (forearm) and drains blood from the surface of the arm into the axillary vein.
In the context of circulation and arterial anatomy, the statement that 'Venous blood flow in the arm is from the wrist to the shoulder' is true.The correct answer is b) False. Venous blood flow in the arm is from the wrist to the shoulder. The brachial vein is the deeper vein of the arm that forms from the radial and ulnar veins in the lower arm and leads to the axillary vein. The brachial artery is the continuation of the axillary artery in the brachium and supplies blood to much of the brachial region. It gives off several smaller branches that provide blood to the posterior surface of the arm in the region of the elbow.
