Which passes through the diaphragm with the Oesophagus?

What are the 3 structures that pass through the diaphragm?
Three important structures pass through the diaphragm: the esophagus, and the two main blood vessels of the lower half of the body, the inferior vena cava, and the descending aorta.
Which structures pass through the diaphragm at T10?
Pathways through the Diaphragm
| Caval Hiatus (T8) | Oesophageal Hiatus (T10) | Aortic Hiatus (T12) |
|---|---|---|
| Inferior vena cava Terminal branches of right phrenic nerve | Oesophagus Right and left vagus nerves Oesophageal branches of left gastric artery/vein | Aorta Thoracic duct Azygous vein |
How does the structure of the diaphragm relate to its function?
It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
What major structures are located in the mediastinum?
The mediastinum houses many vital structures including the heart, great vessels, trachea, and essential nerves. It also functions as a protected pathway for structures traversing from the neck, superiorly, and into the abdomen, inferiorly.
What passes through central tendon of diaphragm?
The caval opening (at the level of the T8 vertebra) passes through the central tendon. This transmits the inferior vena cava and right phrenic nerve.
How does the aorta pass through the diaphragm?
The diaphragm separates the abdominal and thoracic cavities but does allow certain structures to pass through via its three openings: The inferior vena cava passes through the diaphragm at the vena caval foramen. The thoracic duct and azygos vein pass through the aortic hiatus.
Which of the following passes through the aortic hiatus of the diaphragm?

What passes through diaphragm at T12?
Aortic Hiatus (12 letters) – Descending aorta passes through the diaphragm at T12.
What is the structure and function of the diaphragm?
What is Diaphragm Function and Definition. Diaphragm – the thin, flat MUSCLE that forms the floor of the thoracic cavity (chest), establishing a physical barrier between the thoracic cavity and the abdominal cavity. Small openings in the diaphragm allow structures such as the AORTA, inferior VENA CAVA, and ESOPHAGUS to pass through.
What is the structure and location of the diaphragm?
The diaphragm is a C -shaped structure of muscle and fibrous tissue that separates the thoracic cavity from the abdomen. The dome curves upwards. The superior surface of the dome forms the floor of the thoracic cavity, and the inferior surface the roof of the abdominal cavity.
