Which type of tissue aids in the removal of waste from the body?

1. Epithelial tissue

2. Nervous tissue

3. Liquid tissue

4. Connective tissue

The correct answer is: Liquid tissue

The correct answer is liquid tissue, specifically referring to blood and lymph, which play vital roles in waste removal from the body. Liquid tissue includes components such as plasma, which carries nutrients, hormones, and waste products. Blood flows through the circulatory system, actively transporting waste products away from cells to organs responsible for elimination, such as the kidneys and liver. Through this process, unwanted or excess substances are filtered out, helping maintain homeostasis in the body. Lymphatic fluid also assists in transporting waste products and contributes to the immune response, ensuring any pathogens or debris are removed efficiently. Other tissue types mentioned have distinct functions: epithelial tissue primarily covers body surfaces and lines cavities while playing roles in secretion and absorption. Nervous tissue is involved in transmitting signals and processing information within the body. Connective tissue supports, binds, and protects other tissues and organs, but it does not directly facilitate waste removal to the same extent as liquid tissue does.
