The adult male body is about 60% water for a total water content of some 42 litres (9.2 imp gal; 11 US gal). Of these features, the first two are present only during the embryonic stage in the human; the notochord is replaced by the vertebral column, and the pharyngeal gill slits are lost completely. As intelligent as are many other mammals—such as chimpanzees and dolphins—none have achieved the intellectual status of the human species. (Bone and blood are considered specialized connective tissues, in which the intercellular matrix is, respectively, hard and liquid.). In this article we explain the composition of the human body and its various subtle bodies. Organs that work together are grouped into organ systems. Fun science kids love about the human body. The evolution of the human eyebrows is believed to have prevented the influx of sweat into the eyes. You remember a little ditty about the thigh bone being connected to the hip bone, which was in turn connected to the backbone. Human beings are arguably the most complex organisms on this planet. The Human Body App ($2.99) on the iPhone or iPad. [29], The respiratory system consists of the nose, nasopharynx, trachea, and lungs. For information on the structure and function of the cells that constitute the body, see cell. Blood is filtered at the kidneys and liver. [4] At maturity, there are roughly 30[5]–37[6] trillion cells in the body, an estimate arrived at by totaling the cell numbers of all the organs of the body and cell types. In the digestive system, you can feed the body and watch how the food is digested. Printable Human Body Parts for Kids. (2) The musculoskeletal system (also referred to separately as the muscle system and the skeletal system), composed of the skeletal muscles and bones (with about 206 of the latter in adults), moves the body and protectively houses its internal organs. - the leading destination for style, sneakers, luxury, life. New Products added daily An essential workbook that will appeal to all students of anatomy, The Human Body Coloring Book takes an interactive approach to human anatomy that will help users learn, understand, and revisit the subject with ease. In the 20th century, the physiologists Knut Schmidt-Nielsen and George Bartholomew extended their studies to comparative physiology and ecophysiology. This is made up of about 19 litres (4.2 imp gal; 5.0 US gal) of extracellular fluid including about 3.2 litres (0.70 imp gal; 0.85 US gal) of blood plasma and about 8.4 litres (1.8 imp gal; 2.2 US gal) of interstitial fluid, and about 23 litres (5.1 imp gal; 6.1 US gal) of fluid inside cells. Is it true that we only use ten percent of our brain? : alveolus) before being expelled from the lungs when the diaphragm contracts again. Cells in the body function because of DNA. There are eight systems in the human body. (9) The reproductive system, composed of the male or female sex organs, enables reproduction and thereby ensures the continuation of the species. hormones) from one part of the body to another. [48] Claude Bernard (1813–1878) created the concept of the milieu interieur (internal environment), which Walter Cannon (1871–1945) later said was regulated to a steady state in homeostasis.

Then it is swallowed, and moves through the esophagus to the stomach. Phospholipids and the steroid compound cholesterol are major components of the membrane that surrounds each cell. There are several levels of organization to this structure, with each level more complex than the last. The most basic unit is the cell; groups of similar cells form tissues; groups of different tissues make up organs; groups of organs form organ systems; cells, tissues, organs, and organ systems combine to form a multicellular organism. These four basic cell types, together with their extracellular materials, form the fundamental tissues of the human body: (1) epithelial tissues, which cover the body’s surface and line the internal organs, body cavities, and passageways; (2) muscle tissues, which are capable of contraction and form the body’s musculature; (3) nerve tissues, which conduct electrical impulses and make up the nervous system; and (4) connective tissues, which are composed of widely spaced cells and large amounts of intercellular matrix and which bind together various body structures. It gives the body basic structure and the ability for movement. The body is studied by health professionals, physiologists, anatomists, and by artists to assist them in their work. Medicine sees the body like a machine. The main electrolytes in body water outside cells are sodium and chloride, whereas within cells it is potassium and other phosphates.[3]. Characteristic of the vertebrate form, the human body has an internal skeleton that includes a backbone of vertebrae. The ANS is involved in involuntary processes, such as digestion and regulating blood pressure. 1918", "Introduction to Physiology: History And Scope", "Soul Made Flesh: The Discovery of the Brain – and How It Changed the World", Anatomia 1522–1867: Anatomical Plates from the Thomas Fisher Rare Book Library, Reproductive endocrinology and infertility, Bachelor of Medicine, Bachelor of Surgery, https://en.wikipedia.org/w/index.php?title=Human_body&oldid=1008423276, Wikipedia indefinitely move-protected pages, Short description is different from Wikidata, Srpskohrvatski / српскохрватски, Creative Commons Attribution-ShareAlike License. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that’s 2 to 6 pounds of bacteria), but play a vital role in human health. Imagine billions of microscopic parts, each with its own identity, working together in an organized manner for the benefit of the total being. This includes the mechanical, physical, bioelectrical, and biochemical functions of humans in good health, from organs to the cells of which they are composed. This will take this human body project a step farther to teach kids about the organs in their bodies. [10] The study of tissues is called histology and often occurs with a microscope. The body is also host to about the same number of non-human cells[5] as well as multicellular organisms which reside in the gastrointestinal tract and on the skin. The amount of water in the body changes slightly with age, sex, and hydration levels. Examples of organs include the eyes, heart, lungs, liver, and stomach. Various organ systems give the body the ability to live and do things. Doctors want to fix problems with the body. What remains passes on to the large intestine, where it is dried to form feces; these are then stored in the rectum until they are expelled through the anus. [18], The endocrine system consists of the principal endocrine glands: the pituitary, thyroid, adrenals, pancreas, parathyroids, and gonads, but nearly all organs and tissues produce specific endocrine hormones as well. Water is found in the extracellular fluids of the body (the blood plasma, the lymph, and the interstitial fluid) and within the cells themselves. Anatomy 101: Human Body Quiz. ‎Learn anatomy and biology in an interactive model of the human body — the heart beats, guts gurgle, lungs … The human body is a single structure but it is made up of billions of smaller … The human body is about 60 percent water by weight.
