Lymph vessels. Walled, valved structures that carry lymph around the body. Lymph nodes. Small bean-shaped glands that produce lymphocytes, filter harmful substances from the tissues, and contain macrophages, which are cells that digest cellular debris, pathogens and other foreign substances. Major groups of lymph nodes are located in the tonsils, adenoids, armpits, neck, groin and mediastinum.

All plants have tissues, but not all plants possess all three of the following types of tissues: Dermal tissue: Consisting primarily of epidermal cells, dermal tissue covers the entire surface of a plant. Ground tissue: This tissue type makes up most of a plantâs body and contains three types of cells: Parenchyma cells are the most common ground tissue cells. They perform many basic plant cell functions, including storage, photosynthesis, and secretion.
