Question
1. In treating a woman for malignancy in the left breast, the surgeon removes some of her axillary lymph nodes. Following surgery, the patient experiences edema of her left arm. Explain why.
2. Anti-B antibodies of a type A mother rarely affect the RBCs of a type B fetus. Yet anti-D antibodies of an Rh– woman sometimes cross the placenta and hemolyze the RBCs of an Rh+ fetus. Explain this difference based on your knowledge of the five immunoglobulin classes.
3. How does the structure of a B cell differ from that of a plasma cell? Explain how their structural difference relates to their functional difference.
Explanation / Answer
According to the Chegg guidelines I'll answer the first question when more than one question is posted. Post them separately to get the answers.
1) When the surgeon removes axillary lymph nodes, he also must have removed some of the pathway of lymphatic drainage from upper limb. Thus removal results in the accumulation of the tissue fluid in the upper limb and that is why following surgery, the patient experiences edema on her left arm.
