Esophagus

The esophagus is a muscular tube that connects the mouth to the stomach and transports food and liquids through peristalsis. Muscles in the mouth and throat help move food into the esophagus, where a wave of contractions pushes it towards the stomach. The esophagus' coordinated contraction and relaxation propel food or liquid to the stomach.

Ribcage

The ribcage is a bony structure that consists of the sternum (breastbone), the thoracic vertebrae (backbone), and 12 pairs of ribs. The curved shape of the ribs helps to absorb and distribute forces that may be directed toward the chest. This allows the ribcage to protect our vital organs without damaging them.

Stomach

The stomach is an organ in the digestive system. Its main function is to break down the food we eat into smaller particles that can be easily absorbed by the body. When food enters the stomach through the esophagus, it is mixed with digestive juices and broken into chyme.

Lungs

The lungs are located in front of the esophagus and are part of the respiratory system. They are responsible for breathing, which involves the exchange of oxygen and carbon dioxide between the body and the environment. The esophagus and lungs are connected to each other through a tube called the trachea.
