Final answer:
The palatine and lingual tonsils are located along the walls of the oropharynx, with the palatine tonsils near the fauces and the lingual tonsils at the base of the tongue.
Step-by-step explanation:
The palatine and lingual tonsils are located along the walls of the oropharynx. The palatine tonsils are found laterally in the area of the fauces, which is the space between the palatoglossal arch and the palatopharyngeal arch, at the back of the oral cavity. The lingual tonsils are situated at the base of the tongue.
Both sets of tonsils are part of the lymphoid tissue system and play a critical role in trapping and destroying pathogens that enter the body via the oral and nasal cavities. These tonsils are important in the development of immunity against these pathogens.
