What Is The Largest Organ In Your Body – In a multicellular organism, an organ is a collection of tissues united into a structural unit to perform a common function.

In the hierarchy of life, an organ lies between a tissue and an organ system. Tissues are formed from cells of the same type to act together in a function. Tissues of different types combine to form an organ that has a specific function. The intestinal wall, for example, is made up of epithelial tissue and smooth muscle tissue.

Two or more organs working together to perform a specific bodily function form an organ system, also called a biological system or body system.

The tissues of an organ can be broadly classified into parchyma, the functional tissue, and stroma, the structural tissue with supporting, connective, or auxiliary functions. For example, the gland tissue that produces hormones is the parchyma, while the stroma includes the nerves that innervate the parchyma, the blood vessels that oxygenate it, nourish it, and carry away its metabolic wastes, and the connective tissues that provide a suitable place for it must be located and anchored. The main tissues that make up an organ have common embryonic origins, for example coming from the same germ layer. Organs exist in most multicellular organisms. In single-celled organisms such as eukaryotes, the functional analogue of an organ is called an organelle. In plants, there are three main organs.

The number of organs in any organism depends on the definition used. According to a widely adopted definition, 79 organs have been identified in the human body.

With the exception of placozoans, multicellular animals, including humans, have a variety of organ systems. These specific systems are widely studied in human anatomy. The functions of these organ systems often share significant overlap. For example, both the nervous and docrine systems function through a common organ, the hypothalamus. For this reason, the two systems are combined and studied under the name of the neurodocrine system. The same is true for the musculoskeletal system because of the relationship between the muscular and skeletal systems.

Abdominal organs can be classified as solid organs or hollow organs. The solid organs are the liver, pancreas, spleen, kidneys and aral glands. The hollow organs of the abdomen are the stomach, intestines, gallbladder, bladder and rectum.

The term “visceral” contrasts with the term “parietal”, meaning “of or relating to the wall of a part of the body, an organ or a cavity”.

Both terms are often used to describe a membrane or piece of connective tissue, referring to opposite sides.

The level of organ organization in animals can be detected for the first time in flatworms and the most derived phyla, i.e. bilaterians. The least advanced taxa (i.e. Placozoa, Porifera, Ctophora and Cnidaria) do not show consolidation of their tissues into organs.

More complex animals are made up of different organs that have evolved over time. For example, the liver and heart evolved in chordates around 550 to 500 million years ago, while the gut and brain are even older, appearing in the ancestor of vertebrates, insects, molluscs and worms around 700 to 650 million years ago.

Given the ancient origin of most vertebrate organs, researchers have sought model systems in which the organs evolved more directly and, ideally, evolved several times independently. A notable model for this type of research is the placta, which has evolved more than 100 times independently among vertebrates, evolved relatively straight in some lineages, and exists in intermediate forms in extant taxa.

Studies of placental evolution have identified a variety of genetic and physiological processes that contribute to the origin and evolution of organs, including the reuse of existing animal tissues, the acquisition of new functional properties by these tissues, and new interactions. of distinct tissue types.

The study of plant organs is covered by plant morphology. Plant organs can be divided into vegetative and reproductive organs. The vegetative organs of plants include roots, stems and leaves. The reproductive organs are variable. In flowering plants, they are represented by the flower, the seed and the fruit.

In conifers, the organ that carries the reproductive structures is called a cone. In other divisions (phyla) of plants, the reproductive organs are called strobili, in Lycopodiophyta, or simply gametophores in mosses. Common designations for organ systems in plants include shoot and root differentiation. All aerial parts of the plant (in non-epiphytes), including functionally distinct leaf and floral organs, can be classified together in the shoot organ system.

Vegetative organs are essential to maintaining the life of a plant. While there may be 11 organ systems in animals, there are far fewer in plants, where some carry out vital functions, such as photosynthesis, while the reproductive organs are essential for reproduction. However, if there is asexual vegetative reproduction, the vegetative organs are the ones that create the new generation of plants (see clonal colony).

Many societies have an organ donation system, in which an organ from a living or deceased donor is transplanted into a person whose organ is failing. Transplantation of larger solid organs often requires immunosuppression to prevent organ rejection or graft-versus-host disease.

Organ transplants began to take place as scientists learned more about the anatomy of organs. These came later because the procedures were often dangerous and difficult.

The source and method of obtaining the organ to be transplanted are major ethical issues to consider, and because organs as resources for transplantation are always more limited than demand, various notions of justice, including justice distributive, are developed in ethical analysis. This situation will continue as long as transplantation depends on organ donors rather than technological innovation, testing and industrial manufacturing.

The English word “organ” dates back to the 12th century and refers to any musical instrument. By the end of the 14th century, the meaning of the term musical had narrowed to refer specifically to the keyboard instrument. At the same time, a second meaning appears, in reference to a “part of the body adapted to a certain function”.

Plant organs are made up of tissues composed of different types of tissue. The three types of tissues are terrestrial, vascular and dermal.

The adjective visceral, also splanchnic, is used for everything relating to the internal organs. Historically, the viscera of animals was examined by pagan Roman priests such as haruspices or augurs in order to divine the future by their shape, dimensions or other factors.

Aristotle used this word frequently in his philosophy, both to describe the organs of plants or animals (e.g. the roots of a tree, the heart or liver of an animal) and to describe “parts” more abstract of an interconnected whole (e.g. its logical works, taken as a whole, are called Organon).

Some alchemists (e.g. Paracelsus) adopted the Kabbalah’s hermetic division between the seven vital organs and the seven classical planets as follows:

Traditional Chinese medicine recognizes the elevated organs, associated with the five traditional Chinese elements and yin and yang, as follows:

The Chinese associated the five elements with the five planets (Jupiter, Mars, Vus, Saturn and Mercury), in the same way that the classical planets were associated with different metals. The yin and yang distinction is similar to the modern notion of solid and hollow organs. Two crossed lines that form an “X”. It indicates a way to close an interaction or dismiss a notification.

Organ Systems In Humans

It might seem that we should have already identified every structure in the human body, even if we don’t know the function of every cell and organ.

But this hypothesis could be very wrong if the authors of a study recently published in the journal Nature Scientific Reports are right.

Between the spaces in our body—under the skin, lining the gut and lungs, surrounding blood vessels and fascia between muscles, and more—is a fluid-filled network of tissue.

The idea that there are tissues and fluids in these spaces is not new; Interstitial fluid is one of the most important types of fluid in the body, although we didn’t know it was contained in these structures.

But the authors of the new study say this tissue has a unified structure and function throughout the body, making it an organ. Using this definition, it could be the largest organ in the body, occupying a larger volume than our skin.

This organ could help protect the rest of our organs and tissues. This could also
