Esophageal and Cancer
Esophagus (from Greek “carry” and “eat”) or the esophagus is a tube (tube) muscle in vertebrates through which food when it flows from the mouth to the stomach. Food goes through the esophagus by using a peristaltic process.
Meet the pharynx esophagus – which connects the esophagus to the oral cavity – in 6 segments of the spine. According to histology, the esophagus was divided into three parts: the superior (mostly skeletal muscle), the middle (a mixture of skeletal muscle and smooth muscle), and the inferior (mainly composed of smooth muscle).
Esophagus is a hollow tube that transports food and liquids from the throat to the stomach. When a person swallows, the walls of the muscular contraction of the esophagus to push food down into the stomach. The glands in the esophagus produce mucus layer, which maintain the passageway moist and makes swallowing easier. Esophagus is located just behind the trachea (windpipe). In an adult, esophagus is approximately 10 inches in length.
Cancer that began in the esophagus (also called esophageal cancer) is divided into two major types, squalors cell carcinoma and adenocarcinoma, depending on the type of cells are malignant. Squalors cell carcinomas arise in squalors cells that line the esophagus. These cancers usually occur at the top and middle of the esophagus. Aden carcinomas usually develop in the tissue at the bottom gland of esophageal. Treatment is similar for both types of esophageal cancer.
If the cancer spreads out of the esophagus, it is often first go to the lymph-lymph node. -Node is the lymph node structures are small bean-shaped which is part of the body’s immune system. Esophageal cancer may also spread to almost all other parts of the body, including liver, lungs, brain, and bones.
