THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The nasal cavity provides room for the nose and mouth. The dorsal cavity is one long, continuous cavity. The abdominal cavity is frequently divided into six sections. The kidneys and adrenal glands are in the retroperitoneal space behind the abdominal cavity.

Detailed explanation-2: -The nasal passages filter and warm the air, and make it moist before it goes into the lungs. They also contain special cells that are involved in the sense of smell.

Detailed explanation-3: -The pharynx, commonly called the throat, is a muscular, funnel-shaped passageway inside the body. It connects the mouth and nose to the esophagus (leading to the stomach) and larynx (leading to the trachea and then lungs).

Detailed explanation-4: -The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won’t get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.

Detailed explanation-5: -The dorsal cavity is a continuous cavity located on the dorsal side of the body. It houses the organs of the upper central nervous system, including the brain and the spinal cord. The meninges is a multi-layered membrane within the dorsal cavity that envelops and protects the brain and spinal cord.
