b) Ulnar vein         _____ blood from the ulnar and radial veins pour into it.
c) Cephalic vein    _____ deep vein of the lateral aspect of the forearm
d) Axillary vein      _____ Most blood from the upper extremities empty in it
e) Brachial vein     _____ drains blood from the superficial  arm and forearm
f) Media cubital     _____ deep vein of the medial aspect of the forearm
g) Radial vein         _____ collecting blood is usually done using this vein

       3.3 Trace the flow of blood from the hand to the deep veins of the forearm to the heart.

 

3.4 Trace the flow of blood from the heart to the hand passing through the deep arteries of               the forearm.

 

3.5 Which veins do not have a matching artery?

 

4.0 Blood vessels of the thoracic and abdomen region

3. Common hepatic artery ________ blood vessels of the kidneys
4. Azygos veins               ________ divides into three main arteries
5. Abdominal aorta        ________ Blood vessels of the small intestines
6. Phrenic                        ________ returns blood from the large intestines
7. Renal                           ________ blood vessels of the ovaries and testis
8. Hepatic portal vein   ________ artery supplying part of the liver
9. Celiac trunk               ________ largest artery of the abdomen
10. Splenic                     ________ Blood vessels of the diaphragm
11. Superior mesenteric ________ supply blood to the abdominal walls
12. Inferior mesenteric ________ drain intercostal muscles

5.0 Blood vessels of the lower extremities

5.1 Match the vessel with its description

1. Common iliac      _________ these veins connect the tibial veins with the femoral veins
2. Anterior tibial      _________ main arteries and veins of the thigh
3. Femoral                _________ blood vessels found in the foot region
4. Small saphenous     _________ direct connection to the large vessels of the abdomen
5. External iliac          _________ the longest vein of the body
6. Popliteal                 _________ supply and drain blood from the gluteus region
7. Posterior tibial      _________ connects the femoral vessels to the common iliac vessels
8. Great saphenous _________ blood vessels of the anterior part of the leg
9. Plantar                   _________ drains blood from the superficial region of the leg.
