Visceral
Organs refer to collections of tissues with a similar function. Plant and animal life relies on many organs that coexist in organ systems.
Organs are composed of main tissue, parenchyma, and “sporadic” tissues, stroma. The main tissue is that which is unique for the specific organ, such as the myocardium, the main tissue of the heart, while sporadic tissues include the nerves, blood vessels, and connective tissues. The main tissues that make up an organ tend to have common embryologic origins, such as arising from the same germ layer. Functionally related organs often cooperate to form whole organ systems. Organs exist in all organisms. In single-celled organisms such as bacteria the functional analogue of an organ is known as an organelle. In plants there are three main organs.
A hollow organ is a visceral organ that forms a hollow tube, or pouch such as the stomach, intestine, or bladder.
In the study of anatomy, the term viscus is used to refer to an internal organ, and viscera is the plural form.
Seventy-nine organs have been scientifically validated in the human body.
