Nerves connect the spinal cord and brain to the rest of the body. [9] However, not all cells have DNA; some cells such as mature red blood cells lose their nucleus as they mature. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Vintage anatomy charts of the human body showing the skeletal and muscle systems. The adult male body is about 60% water for a total water content of some 42 litres (9.2 imp gal; 11 US gal). It is DNA, passed from parents to offspring, that dictates the inherited characteristics of each individual human. The body as it actually is is mysterious to us. According to Medical News Today, lanugo hair is typically classified as thin, whispy hairs that appear on the body of a fetus. The human body is the structure of a human being.

"Your Body" is a song by American singer Christina Aguilera from her seventh studio album, Lotus (2012). [1] These elements reside in trillions of cells and non-cellular components of the body. 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. [50] Most recently, evolutionary physiology has become a distinct subdiscipline. (8) The endocrine system, composed of the hormone-secreting glands and tissues, provides a chemical communications network for coordinating various body processes. In multiple sclerosis, the immune system attacks the nerve linings, damaging the nerves' ability to transmit signals. Yet the body, like them, is much more than we know.

[35], Each system contributes to homeostasis, of itself, other systems, and the entire body. The tissue that stores fat in humans is called 'adipose tissue'. [31] In asthma, the respiratory system is persistently inflamed, causing wheezing and/or shortness of breath. 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. The body contains trillions of cells, the fundamental unit of life. Your body is scanned, destroyed, then reproduced. Health professionals learn about the human body from illustrations, models, and demonstrations. Water's "stickiness" (from surface tension) plays a part in our body's ability to transport these materials all through ourselves. I invite you to do the same. My perfect beach body will not come from a new diet, a certain weight, or series of exercises. [7] Not all parts of the body are made from cells. Proteins also serve as a major structural component of the body. Flow of charges and ions constitute electric current. The body includes nine major organ systems, each composed of various organs and tissues that work together as a functional unit.

The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age. Fats provide an energy reserve for the body, and fat pads also serve as insulation and shock absorbers. [40], In Ancient Greece, the Hippocratic Corpus described the anatomy of the skeleton and muscles. It removes toxic materials from the blood to produce urine, which carries a variety of waste molecules and excess ions and water out of the body.[33]. Characteristic of the vertebrate form, the human body has an internal skeleton that includes a backbone of vertebrae. Then it is swallowed, and moves through the esophagus to the stomach.

[47] The term physiology was introduced by the French physician Jean Fernel (1497–1558). Ions of phosphorus, potassium, and magnesium, on the other hand, are abundant within the intercellular fluid. [20], The integumentary system consists of the covering of the body (the skin), including hair and nails as well as other functionally important structures such as the sweat glands and sebaceous glands. In the 20th century, the physiologists Knut Schmidt-Nielsen and George Bartholomew extended their studies to comparative physiology and ecophysiology. The process begins with fertilisation, where an egg released from the ovary of a female is penetrated by sperm. The human body is composed of elements including hydrogen, oxygen, carbon, calcium and phosphorus. The thyroid is a butterfly-shaped gland located on the front of your neck. The cell is the basic living unit of the human body—indeed, of all organisms. As intelligent as are many other mammals—such as chimpanzees and dolphins—none have achieved the intellectual status of the human species. The human body is about 60 percent water by weight. For example, see abdominal cavity; adrenal gland; aorta; bone; brain; ear; eye; heart; kidney; large intestine; lung; nose; ovary; pancreas; pituitary gland; small intestine; spinal cord; spleen; stomach; testis; thymus; thyroid gland; tooth; uterus; vertebral column.
