venous: anatomy

What is the direction of flow in veins?

• Distal to proximal

• Proximal to distal

• Lateral to medial

• Medial to lateral

What is the function of hepatic veins?

• Hepatic veins empty blood from the liver and drain blood into the IVC.

• Hepatic veins supply oxygenated blood to the liver.

• Hepatic veins produce bile for digestion.

• Hepatic veins store glycogen for energy.

What happens when two veins join each other?

• They both flow into the new vein. The junction is always the new vein.

• They create a blockage and stop blood flow.

• They form a loop and circulate blood back to the heart.

• They split into multiple smaller veins.

What is the role of venae comitantes?

• Corresponding veins. Paired deep veins.

• Transport oxygenated blood.

• Connect arteries to veins.

• Regulate blood pressure.

Explain the formation of IVC.

• The IVC is formed by the union of the right and left common iliac veins.

• The IVC is formed by the union of the right and left renal veins.

• The IVC is formed by the union of the right and left hepatic veins.

• The IVC is formed by the union of the right and left femoral veins.

What is the longest vein in the body?

• Greater saphenous vein

• Inferior vena cava

• Pulmonary vein

• Jugular vein

Where does the small saphenous vein drain into?

• POP

• Femoral vein

• Great saphenous vein

• Inferior vena cava

What is the function of perforating veins?

• Connect superficial to deep veins

• Transport oxygenated blood to tissues

• Regulate blood pressure

• Store blood for emergencies

Which veins drain into the IVC?

• Renal veins and hepatic veins

• Jugular veins and subclavian veins

• Femoral veins and popliteal veins

• Brachial veins and cephalic veins

What is the role of venous sinuses in the calf muscle pump?

• Potential reservoirs or channels that allow blood to accumulate and be ejected during calf contraction

• They are responsible for oxygenating the blood in the calf muscles

• They help in the absorption of nutrients in the calf muscles

• They are involved in the nerve signaling of the calf muscles
