Blood and lymphatic tissues also play roles in support and protection. Blood transports nutrients, oxygen, and waste products to and from cells, while lymphatic tissues help in immune surveillance and fluid balance.
Blood: This fluid tissue circulates throughout the body, delivering essential elements to cells and removing waste products. It also contains immune cells that protect against pathogens. Lymphatic Tissue: This tissue includes lymph nodes and lymphatic vessels, which transport lymph—a fluid containing infection-fighting white blood cells. Lymphatic tissues are essential for immune system function and maintaining fluid balance in the body.
