Post-mastectomy patients will often present with a compromised lymphatic system, especially those individuals who went through surgical removal of their lymph nodes. Which of the following functions is MOST likely a valuable function of the lymphatic system?
  1. The destruction of foreign bodies in the lymph nodes
  2. The manufacture of growth hormones
  3. The production of edema in the periphery, especially in the upper extremities
  4. The production of red blood cells and platelets
Explanation
Answer: A - Lymph aids the body by producing immune responses, including the creation of antibodies and the destruction of bacteria and other foreign bodies in the lymph nodes. Lymph fluid is quite similar to blood, except it does not contain red blood cells or platelets. The lymphatic system is partially responsible for preventing edema by preventing excessive protein and fluids from accumulating in the interstitial spaces in the body. The loss of this ability will often manifest as lymphedema, especially if the lymph nodes were surgically sacrificed.
