Contacts across the two ribosomal subunits are known as intersubunit bridges. In the eukaryotic ribosome, additional contacts are made by 60S expansion segments and proteins. [ 24 ] Specifically, the C-terminal extension of the 60S protein RPL19 interacts with ES6E of the 40S rRNA, and the C-terminal extension of the 60S protein RPL24 interacts ...
Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract.The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products.
The abdominal cavity is a large body cavity in humans [1] and many other animals that contain organs.It is a part of the abdominopelvic cavity. [2] It is located below the thoracic cavity, and above the pelvic cavity.
The stomach sits on the left side, which is attached to the esophagus tube. Food comes through the esophagus, goes behind all of the other organs in the thoracic cavity, and comes out through the point where the esophagus opens up into the stomach. The stomach is a more acidic environment to aid its role in beginning the major processes of ...
Whilst the muscularis externa is similar throughout the entire gastrointestinal tract, an exception is the stomach which has an additional inner oblique muscular layer to aid with grinding and mixing of food. The muscularis externa of the stomach is composed of the inner oblique layer, middle circular layer, and the outer longitudinal layer.
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
The stomach is distensible, and can normally expand to hold about one litre of food. [4] The shape of the stomach depends upon the degree of its distension and that of surrounding viscera, e.g. the colon. [3] When empty, the stomach is somewhat J-shaped; when partially distended, it becomes pyriform in shape. In obese persons, it is more ...
The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes.
