Question

using the previous diagrams as a guide, fill in the name of the vein that matches each description.

1. affected in varicose veins

1. furthest branch in feet

1. largest vein in body

1. from the kidney

1. returns blood to the right atrium

1. branches into the shoulder and axilla

Explanation:

1. Varicose veins commonly affect the superficial veins in the leg, most often the great saphenous vein, as it is a major superficial vein prone to valve dysfunction.
2. The dorsal venous arch (or digital veins extending to the toes, but the farthest named branch in the foot is the dorsal venous arch, which feeds into larger veins, and the terminal branches are the digital veins of the toes; the most distinct farthest branch is the dorsal venous arch of the foot).
3. The inferior vena cava is the largest vein in the human body, carrying deoxygenated blood from the lower half of the body to the heart, and combined with the superior vena cava, but the single largest is the inferior vena cava.
4. The renal vein is the vein that drains blood from the kidney and carries it to the inferior vena cava.
5. The superior and inferior vena cava both return blood to the right atrium; collectively, or the venae cavae, but the two main veins are superior vena cava (upper body) and inferior vena cava (lower body).
6. The subclavian vein merges with the internal jugular vein to form the brachiocephalic vein, but the axillary vein becomes the subclavian vein as it moves into the shoulder/axilla region; the axillary vein branches from the brachial vein and becomes the subclavian vein in the shoulder, so the axillary/subclavian vein branches into the shoulder and axilla area, specifically the axillary vein serves the axilla and becomes the subclavian vein for the shoulder.

Answer:

1. Great Saphenous Vein
2. Dorsal Venous Arch (Foot)
3. Inferior Vena Cava
4. Renal Vein
5. Venae Cavae (Superior and Inferior)
6. Axillary Vein (becomes Subclavian Vein)
