What tissue also grows rapidly reaching 2x the adult size by age 10?

1. Muscular

2. Lymphoid

3. Epithelial

4. Nervous

The correct answer is: Lymphoid

Lymphoid tissue is the correct answer because it grows rapidly, reaching twice the size of adult tissue by the age of 10. Lymphoid tissue plays a crucial role in the immune system, producing white blood cells and antibodies to help defend the body against infections and diseases. This rapid growth and development of lymphoid tissue during childhood are essential for the proper functioning of the immune system in fighting off pathogens. In contrast, the other tissues mentioned in the options do not typically exhibit the same level of rapid growth and enlargement during childhood. Muscular tissue grows and develops gradually with age and physical activity. Epithelial tissue serves as a protective barrier and undergoes constant renewal and repair but does not exhibit the same rapid growth as lymphoid tissue during childhood. Nervous tissue is crucial for transmitting signals throughout the body but does not undergo the same level of rapid growth and size increase as lymphoid tissue during childhood.
