The viscera or entrails are all the internal organs of the primordial cavities of the human body and animals. The internal viscera come from the mesoderm or endoderm in an embryological way. The cavities of the mammals that contain viscera are the thorax, pelvis, skull and abdomen are splanchnic cavities. In anatomy, the section that studies the viscera is splanchnology.
It is thought that viscera are all those internal organs that are part of the body of a living being, both in humans and in the body of animals.
According to the structure or anatomical nature, we can find two kinds of viscera:
- Hollow, membranous or canicular viscera: these are viscera that show an anatomy in the shape of a hollow sac and are lined with membranous layers. The capes or tunics that are observed in the hollow viscera range from external to internal:
- Muscle layer is formed by smooth muscles, which provide motility to the viscera, it can be found in different directions, longitudinal, oblique and circular. They are considered natural openings in the viscera that give way to the formation of muscles that regularize the content that can occur in the viscera.
- Mucous layer is the deepest layer of the hollow viscus, here are mucous glands that produce secretions that lubricate the viscus.
- Serous, external or adventitial layer.
- Submucosal layer.
- Solid or parenchymal viscera: they are viscera that show two completely different fragments in their anatomical structure, which are the parenchyma, which is a noble tissue of the viscera that provides it with the type of function and is made up of a capsule that encloses and protects it., and we have the stroma which is a tissue that supports and represents the interstitial armor.
The viscera of some animals are edible and provide a high protein content in amounts similar to those of meats but have a higher portion of iron. An example, 9mg should be compared. Beef liver and meat would have 3.40 mg. The organ meats that are most common for consumption are the kidney, liver, heart, tongue, these have a large amount of vitamin B12, iron and proteins.
