Picture Of All Organs In Human Body – Scientists said in a study published Tuesday that they may have found a previously unknown organ — one of the largest organs in the human body and one that could significantly advance our understanding of cancer and many other diseases. Is.

Research published in the journal Scientific Reports shows that a network of dense connective tissues and fluid-filled compartments called the interstitium is a fully developed organ – that is, a group of tissues with a unique structure that performs a specialized function. Like heart or liver.

More than two-thirds of the human body is water, most of which is inside cells. Most of the rest, about 20 percent of the fluid in the body, is “interstitial,” a Latin word that combines “inter,” or “between,” and “sister,” or “to place”—literally. , “Between Other Places.”

The Internal Organs

That fluid and the tissues connecting them are called the interstitium (pronounced “inter-stish-um”), and they’re found throughout the body, just beneath the skin and in the digestive, respiratory and urinary systems.

Whether the interstitium is a true separate organ remains to be determined by further research. Either way, understanding it means “a significant reassessment of the anatomy that affects every organ of the body,” said one of the lead authors, Neil D. Theis, a pathology professor at New York University School of Medicine.

Understanding the interstitium may be particularly important in diagnosing and tracking cancer and other diseases that spread throughout the body. Interstitial fluid is the source of lymph, which sends white blood cells, the body’s immune system infection fighters, to wherever they are needed.

A federal panel of distinguished scientists reported in 2016 that focusing on the immune system may be the key to finding highly effective treatments for cancer. Theisz said in an interview that the new research could be seen in parallel to that work; Furthermore, because the interstitium is found throughout the body, understanding it could have implications for impossible-to-predict systems from head to toe.

“You push the first domino down and when you look up to see where the dominoes have fallen, you realize they’re scattered everywhere,” he said.

The interstitium has been hiding right under the noses of scientists forever, but it took an accident to discover what it actually was.

“There are no photographs of it. There is no depiction of the construction,” Theis said. “It’s just there.”

No one had seen the spaces “in between” before because the way scientists traditionally examine human tissue (by cutting it and treating it with chemicals) eliminates its fluid. The interstitial tissue handled in this way throws off all its fluids and, in short, becomes pancaked like the floor of a collapsed building.

Theis said interstitial tissues typically appear flat and solid under the microscope, not the fluid-filled sacs they actually are.

In 2015, doctors called endoscopists, who peer inside the body using long, flexible tubes with cameras, noticed something strange when they were using a new technique that allows light to see living tissue inside a patient’s bile duct. Adds a laser and a small microscope to deliver. , This type of investigation is described as “in vivo”, meaning that it takes place inside a living organism rather than on dead tissue on a slide.

According to the paper, the endoscopists, David Carr-Locke and Petros Benias, saw a series of interconnected cavities that did not match any known anatomy. They took their images to Theis, and together, they determined that the small torn spots that appeared on traditional biopsy slides were actually the remains of those collapsed compartments.

Once researchers recognized the true nature of the structures, they quickly found them throughout the body, in any places where tissue moved or was compressed by external forces. (In fact, one of their functions may be to act like a shock absorber to protect organs, muscles and blood vessels from breaking when they and the body move, the paper proposes.)

The new method of investigation, the paper says, “demonstrates the power of in vivo microscopy to generate new insights into the anatomy and physiology of normal and diseased tissues.”

At a fundamental level, it says, “Our findings require reconsideration of many normal functional activities and disordered fluid dynamics of various organs in the setting of disease, including fibrosis and metastasis” – that is, the spread of cancer.

Theis said that when he and his colleagues realized what they had found, it meant one fundamental thing: “The microscopic anatomy of the entire body needs to be re-examined.” Dive deeper into specific anatomy and physiology.

In the hierarchy of life, an organ lies between a tissue and an organ system. Tissues are made up of the same type of cells to work together to perform a function. Different types of tissues come together to form an organ that has a specific function. For example, the intestinal wall 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, which is also called a biological system or body system.

The tissues of an organ can be broadly classified as parenchyma, functional tissue and stroma, structural tissue with supportive, connective or supporting functions. For example, the glandular tissue that makes hormones is the parchyma, while the stroma includes the nerves that innervate the parchchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and connective tissue. Tissues that provide suitable space for it. It has to be located and installed. The main tissues that make up an organ have a common embryological origin, such as arising from a single germ layer. Organs are present in most multicellular organisms. In single-celled organisms such as members of eukaryotes, the functional analog of an organ is known as an organelle. Plants have three main organs.

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

Except for placozoans, multicellular animals, including humans, have a wide variety of organ systems. These specialized systems are widely studied in human anatomy. The functions of these organ systems often share significant overlap. For example, both the nervous and endocrine systems operate through a shared organ, the hypothalamus. For this reason, both systems are studied together as the neuroendocrine 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.
