GENERAL HISTOLOGY

Detailed explanation-1: -This statement is false, the trachea is anterior to the esophagus/the esophagus is posterior to the trachea. The esophagus is part of the gastrointestinal tract and carries food and saliva from the mouth to the stomach. The trachea is part of the respiratory system and carries air from the nose/mouth to the lungs.

Detailed explanation-2: -The trachea lies anterior to the esophagus and is connected to it by a loose connective tissue. Posteriorly, it is related to prevertebral muscles and prevertebral fascia covering the bodies of sixth and seventh cervical vertebra. The thoracic duct lies on the left side at the level of the sixth cervical vertebra.

Detailed explanation-3: -It is behind the notch at your lower throat, between the inside edges of your collarbones. In a diagram of your trachea and other respiratory organs, you can see the trachea between the top lobes of the lungs. It is in front of your esophagus (tube that carries food from your mouth to your stomach).

Detailed explanation-4: -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 esophagus has no serosal layer; tissue around the esophagus is called adventitia.

Detailed explanation-5: -The trachea lies in the superior mediastinum. Anteriorly, it is covered from before backward by the manubrium sterni, the remains of the thymus, the left brachiocephalic (innominate) vein, the aortic arch, the brachiocephalic trunk and left common carotid arteries, and the deep cardiac plexus.
