The thymus gland plays a crucial role in the development and maturation of T-lymphocytes, which are a type of white blood cell involved in immune responses. During childhood and adolescence, the thymus gland is actively involved in producing and maturing T-cells. However, as we age, the thymus gland gradually undergoes a process called involution, where it shrinks in size and loses its functionality. This involution of the thymus gland is believed to contribute to the decline in the immune system's ability to effectively respond to invading microbes and pathogens. Therefore, the gradual loss of thymus gland functionality is considered to be the starting point in the diminished immune defense associated with aging. Hence, the correct answer is option 2.
