If lymphatic tissue is removed from the axillary region, what is likely to happen to the arm on that side?

When lymphatic tissue is removed from the axillary region, the primary concern is the disruption of lymphatic drainage from the arm on that side. The lymphatic system plays an essential role in maintaining fluid balance in the tissues by returning interstitial fluid to the bloodstream. If lymphatic drainage is compromised due to the removal of lymphatic tissue, it can lead to an accumulation of fluid, resulting in swelling. This condition is referred to as lymphedema.

The lymphatic system also contributes to immune system functions, but the immediate consequence of its removal is the inability to properly drain excess fluid. This gathered fluid can cause the affected arm to become edematous, characterized by swelling and discomfort.

In contrast, changes such as cyanosis, increased muscle strength, or improved circulation are not directly associated with the removal of lymphatic tissue. Cyanosis relates to inadequate oxygenation of the blood, increased muscle strength would not be a consequence of lymph removal, and improved circulation would not occur since lymphatic removal typically leads to fluid retention rather than enhanced blood flow. Hence, the answer highlighting edema due to lymphatic impairment is the most accurate reflection of the physiological changes expected in this scenario.
