Baby Phelps was born without a thymus gland. Immediate plans were made for a transplant to be performed. In the meantime, baby Phelps was placed in strict isolation. Why was this done?

Thymus gland

Explanation:

Thymus is a primary lymphoid organ where T cells mature, T cells mature in the cortex and migrate to medullaT cells do not produce antibodies, when antigen presenting cells bring antigens in the secondary lymphoid organ, T cells helps in their eliminationThere are two types of T cells: T helper cells and T-cytotoxic cellsT helper cells carries membrane protein on surface and provides defense against both extracellular and intracellular pathogensT cytotoxic cells is the carrier of surface protein and provides defense against intracellular pathogens

So, baby Phelps was placed in strict isolation because it plays a vital role in protecting the baby's immune system
