Outline Of Human Body With Internal Organs – In a multicellular organism, an organ is a collection of tissues that are combined into a structural unit to perform a common function.

In the hierarchy of life, an organ is between a tissue and an organ system. Tissues are made of cells of the same type that work together in a function. Various things combine to form an organ that has a specific function. For example, the intestinal wall is composed of epithelial tissue and smooth muscle tissue.

Two or more organs that work together to perform a body function form an organ system, also called a biological system or body system.

Organ tissues are broadly categorized as parchyma, functional tissue, and stroma, structural tissue with supporting, connective, or auxiliary functions. For example, the tissue that makes hormones is the parchyma, but the stroma contains the nerves that innervate the parchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the connective tissues that provide a cushion. it should be in place and attached. The main components that make up an organ have a common embryological origin, i.e. they arise from the same germ layer. Most multicellular organisms have organs. In single-celled organisms such as members of the Eukaryotes, the functional analogue of an organ is known as an organelle. There are three main organs in plants.

Abdominal organs can be classified as solid organs, or hollow organs. The solid organs are the liver, pancreas, kidneys, kidneys and adrenal glands. The empty abdominal organs are the stomach, intestine, colon, bladder and rectum.

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

Besides placozoans, multicellular animals including humans have a variety of organ systems. These particular systems are extensively studied in human anatomy. The functions of these organ systems often share significant overlap. For example, the nervous and endocrine systems both work through a common organ, the hypothalamus. Therefore, the two systems are combined and studied as the neurodocrine system. The same is true for the musculoskeletal system because of the relationship between the muscular and skeletal systems.

In the study of anatomy, viscera (singular viscera) refers to the internal organs of the abdomen, chest, and pelvic cavities.

Abdominal organs may be referred to as solid organs, or hollow organs. Solid organs include the liver, pancreas, spleen, kidneys, and adrenal glands. Hollow organs include the stomach, intestines, liver, bladder, and rectum.

The word “visceral” is contrasted with the term “parietal”, meaning “of or pertaining to the wall of a body part, organ or cavity”.

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

The relationship of major animal lineages indicates how long ago these animals shared a common ancestor. On the left, important organs are shown, which allows us to determine how long ago they may have developed.

The level of organization in animals can be detected for the first time in flatworms and more sophisticated elephants, i.e. duality. The less developed taxa (ie Placozoa, Porifera, Ctophora and Cnidaria) do not show the consolidation of their tissues into organs.

More complex animals are made up of different organs, which have evolved over time. For example, the liver and heart evolved in chordates 550-500 million years ago, while the gut and brain are even more ancient, having evolved about 700-650 million years ago in the ancestor of vertebrates, insects, molluscs and worms.

Because of the ancient origins of most vertebrate organs, researchers have sought model systems in which organs evolved more systematically, and ideally often evolved randomly. An outstanding model for this type of study is the placta, which is more than 100 times more fully developed in the vertebral column, more regularly developed in some lineages, and present in intermediate forms in extant taxa.

Studies on placental development have shown a variety of genetic and physiological processes that contribute to the formation and development of organs, including the remodeling of existing animal tissues, the acquisition of new functional properties by these tissues, and new relationships. from different tissue types.

The flower is the reproductive organ of the angiosperm. This Hibiscus flower is hermaphroditic, and has stems and petals.

The study of plant organs is included in plant morphology. Plant organs can be divided into vegetative and reproductive. Plant organs include roots, stems, and leaves. The reproductive organs are variable. In flowering plants, they are represented by flowers, seeds and fruits.

In insects, the organ that carries the reproductive structures is called a tentacle. In other divisions (phyla) of plants, reproductive organs are called strobili, in Lycopodiophyta, or simply gametophores in mosses. Names of common organ systems in plants include the variety of flower and root. All plant parts above ground (in non-epiphytes), including the functionally separated leaf and flower organs, can be collectively classified as the flower organ system.

Plant organs are important for sustaining plant life. While animals can have up to 11 organ systems, plants have far fewer, which perform some vital functions, such as photosynthesis, while reproductive organs are important in reproduction. However, if there is asexual vegetative reproduction, the vegetative organs are what create the new generation of plants (see clonal colony).

Many societies have a system for organ donation, in which an organ from a living or deceased donor is transplanted into a person whose organ has failed. Large solid organ transplantation often requires immunosuppression to prevent organ rejection or graft-versus-host disease.

Organ transplantation began as scientists learned more about the anatomy of organs. These came later in time because the procedures were often dangerous and difficult.

Both the source and the method of obtaining organs for transplantation are key ethical issues to consider, and since organs as resources for transplantation are always more limited than their demand, various concepts of justice, including distributive justice, are developed in moral analysis. This situation continues until the transplant relies on organ donations instead of technological innovation, experimentation and industrial production.

The glish word “organ” dates back to the twelfth century and refers to any musical instrument. By the end of the 14th century, the meaning of the term music was narrowed to refer exclusively to keyboard-based instruments. At the same time, a second meaning emerged, for “a part of the body adapted to a specific function”.

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

The adjective visceral, as well as splanchnic, is used for anything connected with internal organs. Historically, animal faces were studied by Roman pagan priests, such as fortune tellers or augurs, to predict the future by their shape, details or other factors.

Aristotle used the word frequently in his philosophy, both to describe plant or animal organs (eg the roots of a tree, the heart or liver of an animal), and to describe the more abstract “parts” of an interconnected whole ( (eg logical works, in their entirety, are referred to as Organon).

Some alchemists (e.g. Paracelsus) accepted the assignment of the Hermetic Qabalah between the vital organs and the seven classical planets as follows:

Traditional Chinese medicine identifies the elev organs, which correspond to the five traditional Chinese elements and to yin and yang as follows:

The Chinese associate the five elements with the five planets (Jupiter, Mars, Vus, Saturn and Mercury), just as the classical planets were associated with different metals. The yin and yang distinction is close to the modern concept of solid and hollow organs.
