Esophagus trachea anatomy. The trachea is a windpipe which belongs to the respiratory system. The esophagus is a muscular tube connecting the throat pharynx with the stomach. Esophagus consists of four histologic layers.

Trachea is a large membranous tube which extends from the larynx to. The trachea or windpipe is a rigid tube about 12 cm 45 in long and 25 cm 1 in in diameter that lies in front of the esophagus figure 1 and 2. Just before entering the stomach the esophagus passes through the diaphragm.

Esophagus also spelled oesophagus relatively straight muscular tube through which food passes from the pharynx to the stomach. The trachea lies behind the sternum breastbone and in front of the esophagus in the area of the chest between the lungs known as the mediastinum. Narrowings and curves of esophagus.

The esophagus can contract or expand to allow for the passage of food. Esophagus is a muscular tube like organ that originates from endodermal primitive. The esophagus is 25.

The trachea is 10 11 cm long. The esophagus lies posterior to the trachea and the heart and passes through the mediastinum and the hiatus an opening in the diaphragm in its descent from the thoracic to the abdominal cavity. The trachea is a median structure but near its lower end deviates slightly to the right resulting in the left main bronchus crossing anterior to the esophagus.

The trachea descends anterior to the esophagus enters the superior mediastinum and divides into right and left main bronchi. The trachea is supported by 16 to 20 c shaped rings of hyaline cartilage. The trachea is a part of the respiratory system while the esophagus is a part of the digestive system.

The trachea is the longer tube but the esophagus is more flexible. The trachea has two parts but the esophagus has three. It divides into the left and right bronchus connected to the left and right lung respectively 1.

The trachea transports air while the esophagus transports food. The esophagus runs behind the windpipe trachea and heart and in front of the spine. Beginning at the necks base just below the voice box the trachea is located in the thoracic or chest cavity in front of the esophagus running along the midline of the human body 4 down to the back of the sternum breastbone.

It passes through the muscular diaphragm before entering the stomach. The beginning of the trachea lies beneath the thyroid gland with the inferior end connecting with the carinathe area in which the main bronchus separates into two bronchi one of which enters each lung. Difference between trachea and esophagus definition.

The esophagus is about 8 inches long and is lined by moist pink tissue called mucosa. Anatomically it lies behind the trachea and heart and in front of the spinal column.
