The diaphragm is also involved in non-respiratory functions. It helps to expel vomit, feces, and urine from the body by increasing intra-abdominal pressure, aids in childbirth, [18] and prevents acid reflux by exerting pressure on the esophagus as it passes through the esophageal hiatus.
The liver synthesises the bulk of lipoproteins. The liver is located in the upper right quadrant of the abdomen and below the diaphragm to which it is attached at one part, the bare area of the liver. This is to the right of the stomach and it overlies the gall bladder. The liver synthesises bile acids and lecithin to promote the digestion of ...
The esophageal hiatus is an oval opening [1] in (sources differ) the right crus of the diaphragm [1] /left crus of the diaphragm, with fibres of the right crus looping around the hiatus to form a sling (upon inspiration, this sling would constrict the esophagus, forming a functional (not anatomical) sphincter that prevents gastric contents from refluxing up the esophagus when intra-abdominal ...
The aorta is situated on the left, the thoracic duct in the middle, and the azygos vein on the right. [1]: 185 The hemiazygos vein may pass through the aortic hiatus [2] or may pass through the diaphragm independently through its own foramen in the left crus.
The right phrenic nerve passes over the brachiocephalic artery, posterior to the subclavian vein, and then crosses the root of the right lung anteriorly and then leaves the thorax by passing through the vena cava hiatus opening in the diaphragm at the level of T8. The right phrenic nerve passes over the right atrium.
The liver is a major metabolic organ exclusively found in vertebrate animals, which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and various other biochemicals necessary for digestion and growth.
The anterior vagal trunk is one of the two divisions (the other being the posterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks represent the inferior continuation of the esophageal nervous plexus inferior to the diaphragm. [2]
Upper and lower human gastrointestinal tract. The esophagus (American English), oesophagus (British English), or œsophagus (archaic spelling) (see spelling difference) all / iː ˈ s ɒ f ə ɡ ə s, ɪ-/; [1] pl.: ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by ...
