Is there a difference between the position of the esophagus and the throat, and between the esophagu

Not a location.

Larynx is a general term for pharynx and larynx. After the oral and nasal cavities, the cavity above the esophagus is the pharynx; The larynx is located in the laryngeal cavity near the upper end of the trachea.

Esophagus: The name of a human organ, i.e. the esophagus. A slender tube connected to the pharynx and the cardia of the stomach is the passage through which food and drink enter the stomach, also known as the "esophagus".

According to the itinerary of the esophagus, it can be divided into three segments: neck, chest and abdomen. The esophagus is mainly composed of the link muscularis (inner layer) and the longitudinal muscular layer (outer layer). Because the contraction and peristalsis of these two muscles force food into the stomach, their main role is to push food into the stomach.

The esophagus is located in front of the spine of the upper body of the body, the upper part is connected to the throat, the lower part is connected to the vertebral body of the spine, and the cardia of the lower stomach is connected, with a total length of about 25 cm and an average diameter of 2 cm. It is an oblate, circular muscular duct that transports food, consisting of a link muscularis and a longitudinal muscular, the mucosa of the esophagus is moist and smooth, and pink in color, and the mucosa of the lower esophagus is slightly light gray.

The esophagus can be divided into three segments: neck, chest, and abdomen according to the stroke. Esophageal main. Since the contraction and peristalsis of these two muscles, forcing food into the stomach, its main role is to push food into the stomach.

The esophagus is behind the trachea, and the epiglottis (larynx) is the demarcation point.

There is a difference between the esophagus and the throat, and the differences are as follows:

1. The position in the human body is different.

The pharynx is a general term for the pharynx and larynx, generally speaking, after the oral and nasal cavity, the cavity above the esophagus is the pharynx, and the upper end of the trachea in the laryngeal cavity is the larynx.

The esophagus is a muscular channel, and the piriform fossa on either side of the throat is the entrance to the esophagus, and the piriform fossa is on either side of the glottis.

2. The functions are different.

Below the throat is the esophagus, through which many of the body's meridians pass, so the throat is closely related to the lesions of certain internal organs and meridians.

The esophagus connects the throat to the stomach, and the esophagus itself does not have any digestive function, but its main function is to help transport food into the stomach, so the throat is two parts that are connected.

Throat: Esophagus:

Below the throat is the esophagus, and on the side is the trachea.

The opening of the esophagus is located in front of the spine. The upper end meets the pharynx at the height of the lower border of the 6th cervical vertebra, and the lower end passes through the diaphragm and connects with the cardia of the stomach on the left side of the 11th thoracic vertebra, with a total length of about 25 cm, and a length of about 40 42 cm from the middle incisor to the end of the esophagus.

The mucosa of the esophagus is moist, smooth, and pink, and the lower esophageal mucosa is slightly light gray. There are 7 10 longitudinal folds on the mucosa, convex towards the lumen, which facilitates the downflow of fluid.

Obviously, this cannot be said from the perspective of the great withering body of human silver. The esophagus includes: pharynx, larynx, and esophagus.

But the neck only occupies a large part of the esophagus.

The above is purely my understanding, if there is a mistake, please point out).

Hello, this may be related to pharyngitis or reflux.

Sexual esophagitis is related to slippery oak, of course, at this age, it is still necessary to have a must-shoot eggplant for a barium swallow or gastroscopy, and it will be carried out after the diagnosis is clear**.

The esophagus is located in the sternum**, behind the trachea, in front of the thoracic vertebrae!

The oesophagus is the narrowest part of the digestive tract, a long tubular organ with a narrow front and back. The upper end is about the lower edge of the sixth cervical vertebra and meets the pharynx, descends along the anterior direction of the spine, passes through the superior and posterior mediastinum of the thoracic cavity, and then passes through the esophageal hiatus of the diaphragm to enter the abdominal cavity, and the height of the eleventh thoracic vertebra continues to the stomach and cardia. The total length is about 25 cm.

It has a typical structure of the digestive tract, which is divided into mucosa, submucosa, muscularis and adventitia. There are 7 10 longitudinal folds on the mucosa, convex towards the lumen, which facilitates the downflow of fluid. As the bolus passes through the lumen, these folds flatten due to muscle relaxation and the lumen expands, allowing the bolus to pass through.

The submucosa is hypertrophied and consists of connective tissue with large blood vessels, nerves, lymph, and esophageal glands. The muscle layer is the inner ring and the outer longitudinal. It is about 2 mm thick, with elastic fibers in between, and the adventitia is composed of loose connective tissue, rich in blood vessels, lymphatic vessels, and nerves.

The upper 1 3 segments of the human esophagus are skeletal muscles, the middle 1 3 are skeletal and smooth muscles, and the lower 1 3 segments are completely smooth muscles. The upper 1 3 segments are innervated by the glossopharyngeal nerve, and the remaining 2 3 segments are motor nerves, mainly from the vagus nerve in the neck. The lowest part of the esophagus, about 2 4 cm, is located in the abdominal cavity and forms the functional esophageal sphincter.

It is a high-pressure zone with an internal pressure about 15 40 mm Hg (1 mm Hg kPa) higher than the atmospheric pressure, and this high-pressure zone is also the starting part of the stomach. At rest, the internal pressure at the beginning of the stomach is only about 5 mm Hg. May prevent food from the stomach from returning to the esophagus.

The esophagus in the human body which distinguishes it from the throat is.

Hello, the throat and esophagus are not the same organ. The pharynx is divided into three parts from top to bottom, nasopharynx, oropharynx, and laryngopharynx. The oropharynx is connected downward to the esophagus and belongs to the digestive tract, and the laryngopharynx is connected downward to the trachea and belongs to the respiratory tract. The esophagus is a section of tube that connects the throat to the stomach.
