The spleen is innervated by the splenic plexus, which connects a branch of the celiac ganglia to the vagus nerve. The underlying central nervous processes coordinating the spleen's function seem to be embedded into the hypothalamic-pituitary-adrenal-axis, and the brainstem, especially the subfornical organ. [17]
There are several organs and other components involved in the digestion of food. The organs known as the accessory digestive organs are the liver, gall bladder and pancreas. Other components include the mouth, salivary glands, tongue, teeth and epiglottis. The largest structure of the digestive system is the gastrointestinal tract (GI tract).
An organ system is a biological system consisting of a group of organs that work together to perform one or more functions. [1] Each organ has a specialized role in an organism body, and is made up of distinct tissues .
Every day, seven liters of fluid are secreted by the digestive system. This fluid is composed of four primary components: ions, digestive enzymes, mucus, and bile. About half of these fluids are secreted by the salivary glands, pancreas, and liver, which compose the accessory organs and glands of the digestive system.
In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific ...
A splenocyte is a white blood cell that resides in the spleen and are involved in functions of the spleen, like filtering blood and the immune response. [1]Splenocytes consist of a variety of cell populations such as T and B lymphocytes, dendritic cells and macrophages, which have different immune functions.
Gut-associated lymphoid tissue (GALT) [1] is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut. Owing to its physiological function in food absorption, the mucosal surface is thin and acts as a permeable barrier to the interior of the body.
A biological system consisting of a group of organs that work together to perform just one function. Body parts Somewhat arbitrarily defined sections on the body based on what humans have historically thought was one thing with a primary function. Organs: A collection of tissues that structurally form a functional unit specialized to perform a ...
