Questions: Match the following: two pairs of elliptically shaped bodies of lymphoid tissue. bones that change the flow of inspired air to moisturize and warm it better. a cartilaginous framework between the pharynx and trachea. Carries air from the nose to the larynx and food from the mouth to the esophagus.

To match the descriptions provided with their corresponding anatomical structures, let's analyze each one:

1. Two pairs of elliptically shaped bodies of lymphoid tissue.

   • This description matches the tonsils. The tonsils are lymphoid tissues located in the pharynx, and they include the palatine tonsils and the lingual tonsils, which are often described as being elliptical in shape.

2. Bones that change the flow of inspired air to moisturize and warm it better.

   • This description refers to the nasal conchae (also known as turbinates). These are curved bones in the nasal cavity that help to increase the surface area for air to be humidified and warmed as it passes through the nasal passages.

3. A cartilaginous framework between the pharynx and trachea.

   • This description matches the larynx. The larynx is a cartilaginous structure that sits between the pharynx and the trachea, playing a crucial role in breathing, voice production, and protecting the trachea against food aspiration.

4. Carries air from the nose to the larynx and food from the mouth to the esophagus.

   • This description refers to the pharynx. The pharynx is a muscular tube that serves as a pathway for air traveling from the nasal cavity to the larynx and for food traveling from the mouth to the esophagus.

In summary:

• Two pairs of elliptically shaped bodies of lymphoid tissue: Tonsils
• Bones that change the flow of inspired air to moisturize and warm it better: Nasal conchae
• A cartilaginous framework between the pharynx and trachea: Larynx
• Carries air from the nose to the larynx and food from the mouth to the esophagus: Pharynx
