Question

18. Damage to main lymphatic ducts may cause death from the loss of serum proteins 19. Lymphatic capillaries and blood capillaries both play important roles in the absorption of prote from tissue spaces. 20. Activities that result in central movement, or flow, of lymph are called Jymphokinetic actions 21. Lymphatic vessels run parallel to veins and form frequent anastomoses with them 22? The valves in the lymphatics are more numerous in the larger vessels. 23. Lymph nodes, or glands, are perfectly round structures 24. Lymph nodes may range from 1 mm to more than 20 mm in diameter. 25. The passive compression of the body's soft tissues may act as a lymphokinetic factor. 26. When an infection is present, germinal centers form and the lymph node begins to release lymphocytes, some become antibody-producing plasma cells 27. Lymph nodes contain reticuloendothelial cells that produce certain red blood cells. 28. Germinal centers are areas of rapidly dividing lymphocytes within a cortical node. 29. The supratrochlear lymph nodes are located in the neck along the stemocleidomastoid muscle 30. The inguinal lymph nodes are located in the groin. 31. Even though some lymph nodes occur in clusters, most occur as single nodes. 32- The lymphatic tissue of lymph nodes serves as the site of the final stages of maturation fr some types of lymphocytes and monocytes that have migrated from the bone marrow 33. The cutancous lymphatic plexus drains lymph from the breast 34. Cancer of the breast is one of the most common forms of malignancy in women 35. The majority of lymph from the breast enters the axillary lymph nodes breast- -the mammary gland and the surrounding tissues-is drained by six sets of lymphatic vessels 37. Axillary node enlargement may be a sign that breast cancer cells have spread to the nodes

Explanation / Answer

34. Ans - True

Explanation:

Cancer most commonly found in women is breast cancer and in the U.S., it is the 2nd most common cause of death in women. Among the breast cancer, Invasive Ductal Carcinoma (IDC) is the most common form of breast cancer.

35. Ans- false

Explanation:

It is found that about 75% of lymph of breast that drains into the axillary lymph nodes and it is important for the identification of breast cancer.

36. Ans- false

There are two types of lymph vessels of the breast that drain the breast-mammary gland and surrounding tissue:

a. Those lymphatic which originate in and drain the substances of the breast along with the skin of areola and nipple

b. Those that originate in and drain the substances over the breast except areola and nipple.

37. Ans- True

Explanation:

The most common symptoms of a spread of cancer into nodes is to feel hard or enlargement of axillary lymph nodes. Following are the symptoms if cancer spread into the lymph nodes:

a. Swelling or enlargement of axillary lymph nodes

b. Swelling of the breastbone
