Organs of the body

internal organs of the human body in spanish

The organs generally function within systems or apparatuses, that is to say, interpenetrated with other organs to carry out a function. Thus, in the digestive system we have the liver, the stomach or the intestine, each of which has its own function.

The eyes, the skin and the heart are considered as organs, but not all of them have the same importance. The term vital organs is used to refer to those without which one cannot live, such as the lungs or the pancreas.

They are the main organs of the respiratory system. In them the carbon dioxide-laden blood is cleaned and charged with oxygen. The passage of oxygen into the blood occurs through the alveoli, which are the branches of the bronchi inside the lungs.

They are two organs of the body located in the lower back or back area of the abdomen. Their main function is to filter the blood and help in the elimination of the wastes present in it.

The liver also fulfills other functions such as the production of bile, which is essential for digestion. It is also in charge of transforming part of the food into carbohydrates and is capable of manufacturing proteins.

An organ (from the Latin órganum, ‘tool’), in biology and anatomy, is a grouping of various tissues that form a structural unit responsible for the fulfillment of a specific function within a multicellular organism.

Not all animals have all the organs, only the so-called higher animals -because they have reproductive apparatus- (vertebrates: birds, mammals, reptiles, fish and amphibians), have all or most of the related organs.

Higher plants or spermatophytes are those that reproduce by seeds. In plant anatomy the following structures present in tracheophytes (vascular plants) are considered as organs:

The different tissues, both animal and plant, that make up an organ constitute its morphology (histoarchitecture) and provide functionality (histophysiology). The stroma is the organic fraction that corresponds to the structural elements, and the parenchyma is the physiological fraction of the organ.

The internal organs are asymmetrically positioned in our body. Except for rare cases, the liver is always more to the right, while the stomach and the heart are always situated to the left.

How this happens and for what purpose is not well understood. The answer involves understanding how the organs are formed from the time we are in our mother’s womb; how the cells that compose us communicate with each other and how they can distinguish the left side from the right side.

People belong to a group of animals known as bilaterians. The body of a bilaterate animal has, as its name suggests, bilateral symmetry. This implies that our left side is the mirror image of the right side.

The internal organs are arranged in our trunk in an asymmetrical manner: on the left side are the heart, stomach, spleen and pancreas; while most of the liver is on the right.

In some people and animals, the organs invert their position with respect to the central axis of the body in a mirror image of those of a normal person. The heart is oriented to the right, the liver to the left, and so on. These people are known as situs inversus, while situs solitus are people with the majority accommodation.

The first part is the study of the human body in which the concepts and fundamentals of the tissues and the apparatuses and/or systems that make up the zones and regions of the body are developed. In the second part, we study the factors of health with special emphasis on food as the basis of proper nutrition of cells and metabolism and therefore the proper functioning of systems and organs of the body.

In this module we will study the different types of tissues that make up the apparatuses and systems of the human body as well as the importance of their function in the proper development of human physiology.

Some epithelia present modifications on the apical side of the outermost cells (microvilli: brush border, striated sheet, stereocilia; cilia or flagella) for special functions, in such cases the mentioned characteristics can also be used to classify tissues.

Exocrine glands release their secretions into an internal cavity or to the outside of the organism. They may do so directly, as is the case with goblet cells or the secretory surface cells of the stomach, both of which are intraepithelial, or by means of an excretory duct that communicates the secretory portion with the lining epithelium.
