The Human Body Chart
Chemically, the human body is mainly composed of water and organic compounds, that is, lipids, proteins, carbohydrates and nucleic acids. The human body is made up of approximately 60 percent water by weight.
The nine major organ systems of the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.
The human body, the physical substance of the human body, is composed of living cells and extracellular material organized into tissues, organs, and systems.

Humans are in fact animals, specifically members of the order Primates in the suborder Chordata, phylum Vertebrata. Like all chordates, the human animal has a bilaterally symmetrical body, characterized during development by a dorsal support rod (notochord), gill slits in the pharyngeal region, and a hollow dorsal nerve cord. Of these characteristics, the first two are present only in the embryonic stage of man; The notochord is replaced by the vertebral column and the pharyngeal gill slits are completely lost. The dorsal nerve cord is the spinal cord in humans; It last for ever.
The human body has an internal skeleton that includes a backbone of vertebrae. Typical of mammalian structures, the human body presents features such as hair, mammary glands and highly developed senses.

However, beyond these similarities, there are some profound differences. Among mammals, only humans have a predominantly bipedal posture, which has greatly modified the overall body plan of mammals. (Even the kangaroo, which hops on two legs when moving fast, walks on all fours and uses its tail as a “third leg” when standing.) Furthermore, the human brain, especially the neocortex, is highly developed. In the animal kingdom. Like many other highly intelligent mammals, such as chimpanzees and dolphins, humans have not reached the intellectual status of humans.
Chemically, the human body is mainly composed of water and organic compounds, that is, lipids, proteins, carbohydrates and nucleic acids. Water is found in the body’s extracellular fluids (blood plasma, lymph, and interstitial fluid) and within the cells themselves. It acts as a solvent in which the chemistry of life cannot take place. The human body is made up of approximately 60 percent water by weight.
Lipids, mainly fats, phospholipids and steroids, are the main structural components of the human body. Fats provide the body with energy storage and fat pockets act as an insulator and shock absorber. Phospholipids and the steroid compound cholesterol are important components of the membrane that surrounds each cell.

Proteins also act as the main structural components of the body. Like lipids, proteins are an important component of cell membranes. Additionally, extracellular materials such as hair and nails contain proteins. So is collagen, the fibrous, elastic material that makes up most of the skin, bones, tendons, and ligaments in the body. Proteins also play many functional roles in the body. Particularly important are cellular proteins called enzymes that catalyze the chemical reactions necessary for life.
Carbohydrates are present in the human body primarily as fuel, as simple sugars that travel through the bloodstream, or as a storage compound, glycogen, found in the liver and muscles. Small amounts of carbohydrates are also found in cell membranes, but unlike plants and many invertebrates, the human body has few structural carbohydrates.
Nucleic acids constitute the genetic material of the body. Deoxyribonucleic acid (DNA) carries the body’s hereditary master code, the instructions by which each cell operates. The hereditary traits of each individual are determined by the DNA passed from parents to children. Ribonucleic acid (RNA) comes in many forms and helps carry out the instructions encoded in DNA.
Physiology Explained: The Study Of How The Human Body Works
In addition to water and organic compounds, the body also contains various inorganic minerals. Among them, calcium, phosphorus, sodium, magnesium and iron stand out. Calcium and phosphorus combine to form calcium phosphate crystals and make up a large part of the bones in the body. Like sodium, calcium is present as ions in the blood and interstitial fluid. On the other hand, phosphorus, potassium and magnesium ions are abundant in the intercellular fluid. All of these ions play an important role in the body’s metabolic processes. Iron is found primarily as part of hemoglobin, the oxygen-carrying pigment in red blood cells. Other mineral elements in the body, found in minimal but necessary concentrations, include cobalt, copper, iodine, manganese and zinc.
The diagram shows the five levels of organization in a multicellular organism. The most basic unit is the cell; Groups of similar cells form tissues; Different groups of tissues make up the organs; Groups of organs form organ systems; Cells, tissues, organs, and organ systems combine to form a multicellular organism.
The cell is the basic component of the human body; in fact, of all living beings. The human body contains trillions of cells, each capable of growing, metabolizing, responding to stimuli, and, with few exceptions, reproducing. Although there are approximately 200 different types of cells in the body, they can be divided into four basic classes. These four types of basic cells and their extracellular material constitute the basic cells of the human body:

Bone and blood are considered special connective tissues in which the intercellular matrix is solid and fluid, respectively.
The next level of organization of the body is the organ. An organ is a group of tissues that constitute a specific structural and functional unit. Thus, the heart is an organ made up of four tissues whose function is to pump blood throughout the body. Of course, the heart does not function in isolation; It is part of a system made up of blood and blood vessels. So the highest level of the body is the organ system.
The body consists of nine major organ systems, each of which is made up of several organs and tissues that function as a functional unit. The main components and main functions of each system are: Anatomy and physiology are two fields of study related to understanding the structure and function of the human body. Anatomy is the study of the structure and organization of the body, including the examination of organs, tissues, and cells. Physiology, on the other hand, is the study of the body’s functions and processes, including how the body’s organs and systems work together to maintain homeostasis. It involves the study of the systems that control bodily functions such as circulation, respiration, digestion and excretion.
Organ Systems In Humans
Human anatomy is the study of the structure and organization of the human body. It involves the examination and analysis of the various organs, tissues and systems that make up the human body and the relationships between them.
Depending on the level of organization studied, anatomy can be divided into two types:
Human physiology studies the structure and function of individual organs, such as the heart, lungs, liver, and kidneys, and the interactions between them. It includes the study of the circulatory, respiratory, digestive and excretory systems, as well as the regulation of body temperature, fluid balance and acid-base balance.
Organs Of The Body Chart
The circulatory system is responsible for transporting blood throughout the body. It is made up of the heart, blood vessels and blood. The heart pumps blood through arteries, which carry oxygen and nutrients to the body’s tissues. Veins carry deoxygenated blood back to the heart, where it is pumped to the lungs for reoxygenation.
The respiratory system is responsible for gas exchange between the body and the environment. It is made up of the nose, trachea, trachea and lungs. When we breathe, air enters through the nose and travels to the windpipe and windpipe.
