The diagram shows five levels of organization in a multicellular organism. Particularly important are cellular proteins called enzymes, which catalyze the chemical reactions necessary for life. For a description of how the body develops, from conception through old age, see aging; growth; prenatal development; human development. Although there are some 200 different types of cells in the body, these can be grouped into four basic classes. The respiratory system allows us to take in vital oxygen and expel carbon dioxide in a process we call breathing. (Bone and blood are considered specialized connective tissues, in which the intercellular matrix is, respectively, hard and liquid.). The male reproductive system includes the penis and the testes, which produce sperm. 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 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. Although there are some 200 different types of cells in the body, these can be grouped into four basic classes. Does insulin regulate the level of sugar in the body? (9) The reproductive system, composed of the male or female sex organs, enables reproduction and thereby ensures the continuation of the species.

Live Science is part of Future US Inc, an international media group and leading digital publisher. The urinary system keeps our body healthy by removing dangerous waste products from our blood and expelling them in the form of urine. Conventional biology emphasizes that human expression is controlled by genes and is under the influence of nature. Of course, the heart does not function in isolation; it is part of a system composed of blood and blood vessels as well. So also is collagen, the fibrous, elastic material that makes up much of the body’s skin, bones, tendons, and ligaments. During conception, a sperm cell fuses with an egg cell, which creates a fertilized egg that implants and grows in the uterus. Our editors will review what you’ve submitted and determine whether to revise the article. (3) The respiratory system, composed of the breathing passages, lungs, and muscles of respiration, obtains from the air the oxygen necessary for cellular metabolism; it also returns to the air the carbon dioxide that forms as a waste product of such metabolism. Human body, the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems. Human anatomy and physiology are treated in many different articles. The body's muscular system consists of about 650 muscles that aid in movement, blood flow and other bodily functions.

The liver has many functions, including detoxifying of harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile and production of blood-clotting proteins. The endocrine system is a system of glands that make hormones. Humans have five vital organs that are essential for survival. Ribonucleic acid (RNA), of which there are several types, helps carry out the instructions encoded in the DNA. Humans are, of course, animals—more particularly, members of the order Primates in the subphylum Vertebrata of the phylum Chordata. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. The church has many members, yet remains one body, and each member plays a vital role. All of these ions play vital roles in the body’s metabolic processes. An organ is a group of tissues that constitutes a distinct structural and functional unit. For detailed coverage of the body’s biochemical constituents, see protein; carbohydrate; lipid; nucleic acid; vitamin; and hormone. It is a female sex hormone released by the ovaries. The body includes nine major organ systems, each composed of various organs and tissues that work together as a functional unit. In addition to detoxifying poisonous substances, it also manufactures proteins and hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world. (6) The excretory system, composed of the kidneys, ureters, urinary bladder, and urethra, removes toxic nitrogen compounds and other wastes from the blood. The human body is the structure of a human being.It is composed of many different types of cells that together create tissues and subsequently organ systems.They ensure homeostasis and the viability of the human body.. Other mineral constituents of the body, found in minute but necessary concentrations, include cobalt, copper, iodine, manganese, and zinc. The human body consists of trillions of cells, each capable of growth, metabolism, response to stimuli, and, with some exceptions, reproduction. The human body contains nearly 100 trillion cells. They tend to think the contents of the body are what they have seen being put into or coming out of it, such as food and blood.
