venous: anatomy

What is the direction of flow in veins?

• Distal to proximal

• Proximal to distal

• Lateral to medial

• Medial to lateral

Match each vein or vein pair to its next drainage step in the upper extremity as shown in the diagram and notes.

• Radial and Ulnar veins

• Drain into Brachial vein

• Axillary and Cephalic veins

• Join to form Axillary vein (both drain into axillary)

• Brachial and Basilic veins

• Join to become Subclavian vein

Identify the venae comitantes of the upper extremities as labeled in the diagram and described in the content.

• Cephalic, Basilic, Axillary

• Radial, Ulnar, Brachial

• Subclavian, Innominate, SVC

• Portal, Splenic, SMV

what are the indicated superificial veins below

• cephalic

• basilic

• brachial

• ulnar

Venous valves are described as bicuspid extensions of which layer?

• Medial layer

• Adventitial layer

• Intimal layer

• Muscular layer

According to the diagram and notes on venous return, which two veins join to form the brachiocephalic (innominate) vein?

• Axillary and cephalic veins

• Subclavian vein and Internal Jugular Vein (IJV)

• Radial and ulnar veins

• Superior vena cava (SVC) and inferior vena cava (IVC)

Match each vein to its characteristic course or connection as shown in the diagram.

• Axillary vein

• Superficial vein that courses lateral and joins axillary to become subclavian

• Cephalic vein

• Formed by brachial and basilic; drains into subclavian

• Basilic vein

• Superficial vein that courses medial and joins brachial to form axillary

SVC carries blood to the _____ of heart

• RT atrium

• LT atrium

• LT ventricle

• Rt ventricle

Using the venous return to the heart diagram and notes, which sequence correctly describes the pathway of venous blood from the subclavian and internal jugular veins to the heart?

• Subclavian + IJV → Brachiocephalic (Innominate) → SVC → Right atrium

• Subclavian + IJV → MPV → Liver → SVC

• Subclavian + IJV → Axillary → Cephalic → Right atrium

• Subclavian + IJV → IVC → Left atrium

The right and left innominate (brachiocephalic) veins drain into the _______.

• Superior vena cava (SVC)

• Axillary and cephalic veins

• Subclavian vein and Internal Jugular Vein (IJV)

• Radial and ulnar veins
