Final answer:
The lymphatic structures that form from pharyngeal pouches include the palatine tonsils and the thymus gland.
Step-by-step explanation:
The lymphatic structures that form from the pharyngeal pouches are the palatine tonsils and the thymus gland. The palatine tonsils are located on each side of the pharynx, while the thymus gland is a specialized primary lymphoid organ of the immune system. Both of these structures are integral components of the body's lymphatic and immune systems. The lingual tonsils are located at the base of the tongue, and along with the palatine tonsils, they are part of the tonsil family—the lymphoid tissues located in the pharyngeal region—but they do not form from pharyngeal pouches as the palatine tonsils and thymus do.
