Overview on Organs of the human body

The concept of body systems

Body systems: biological systems that consist of organs and tissues that work together to perform important body functions. Some organs may be involved in body systems if they serve more than one function. All body systems are necessary for the organism to survive and reproduce. Different body systems consist of a set of organs that work together as a single unit for the body to be healthy and move efficiently.

Components of body systems

Respiratory system: data that consists of nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system also has important functions: oxygen enters our bodies, which we need for our cells to live and function properly; and helps to eliminate carbon dioxide.

Circulatory heart apparatus: it is a network consisting of blood, blood vessels and the heart. This network supplies tissues in the body with oxygen and other nutrients, transports hormones, removes unnecessary waste from the body.

Digestive system: is a collection of organs that work together to achieve food into energy and nutrients essential to feed the body completely. Food passes through a long tube inside the body known as the alimentary canal. The gastrointestinal tract consists of the oral cavity, pharynx, esophagus, stomach, small intestine and large intestine. In addition to the gut, there are several important accessory organs that help the body digest food but do not pass through it. Complementary organs of the digestive system include teeth, tongue, salivary glands, liver, gall bladder and pancreas.

Urinary system: it is a drainage system to get rid of urine in the body, which consists of waste and excess fluid. For normal urination to occur, all parts of the body in the urinary tract must work together in the correct order. The urinary system consists of the kidney, ureter, bladder and urethra. More common diseases that can affect the urinary system include urinary infections, kidney stones, urinary incontinence, kidney tumors and kidney failure.

Reproductive system: it is the biological system composed of all the anatomical organs involved in the sexual reproduction of man. The main function of the reproductive system is to ensure the survival of species through the production of eggs and sperm and for the production of hormones. The reproductive system consists of female reproductive glands such as the ovaries, and male ones such as the testicles, which are responsible for producing eggs and sperm.

Immune system: the immune system of organs, cells and special chemicals that mimic infection (microbes). The main parts of the immune system are: white blood cells, antibodies, complement system, lymphatic system, spleen, thymus gland, bone marrow. These are the parts of the immune system that fights infections effectively.

Lymphatic system: it is a network of tissues and organs that helps eliminate toxins, waste and other unwanted substances in the body. The primary function of the lymphatic system is to transport lymph, a fluid that contains white blood cells that resist infection throughout the body. The lymphatic system consists primarily of lymph vessels, which resemble veins and capillaries of the circulatory system. The vessels are connected to the lymph nodes, where the lymph is filtered. The tonsils, adenoids, spleen and thymus are also part of the lymphatic system.

Endocrine system: it is a group of glands that produce hormones, it has a role in the metabolism, the endocrine system also contributes to growth and development and performs tissue functions and sexual function and has the role of reproduction, sleep and mood among others. System consists of the endocrine glands pituitary gland thyroid gland parathyroid glands adrenal glands pancreas ovaries (female) testes (in males). In general, the gland selects substances from the blood, removes them, processes them and secretes the final chemical product to be used somewhere in the body. The endocrine system affects almost every organ and cell in the body.

The muscular system: it is responsible for the movement of the human body. It is associated with the bones of the structural system about 700 named muscles that make up almost half of the body weight. Each of these muscles is a separate organ composed of skeletal muscle tissue, blood vessels, tendons and nerves. Muscle tissue is also found within the heart, digestive organs and blood vessels. In these organs, muscles work to move substances throughout the body.

There are three types of muscles, namely the heart muscle, smooth muscle, and skeletal muscle. Muscles provide strength, balance, movement and heat to warm the body and help supply the body with energy.

Nervous system: is a complex set of nerves and specialized cells known cells neurotransmitters that transmit signals between different parts of the body. It is basically the electrical wiring of the body. Structurally the nervous system is made up of two components: the central nervous system and peripheral nervous system.


Functionally, the nervous system has two main subsections: the volitional or autonomic component. The autonomic nervous system regulates certain body processes, such as blood pressure and respiratory rate, that work without conscious effort. Nerves are cylindrical bundles of fibers that start from the brain and central cord and branch to every other part of the body.

Skeletal system: it is a collection of bones interconnected together through tendons and joints, humans have 206 bones. Cartilage forms in the mother's womb and begins to turn into hard bones a few months after the baby is born.


The structural device is divided into:


1-peripheral skeletal system: the skeleton of the upper limb which includes the bones of the shoulder, humerus, forearm, wrist, Combs or palm and fingers.


2. Central Structural apparatus: includes skull, thoracic cage, spine and pelvis.


The importance of the structural organ give the body the characteristic prop, rigidity and shape, also keeps the connection of muscles, ligaments and tendons together, helps the body to move and move smoothly, has an important role in protecting the internal organs of the human body, such as the brain protected by the skull, heart and lungs protected by the rib cage.

Excretory system: it is a system in the body of an organism that performs the function of excretion, which is the physical process of discharging waste, compounds and substances harmful to the body resulting from continuous metabolic processes. Several parts of the body are involved in the process of getting rid of certain excretory substances, such as sweat glands, liver, lungs, kidney system, skin, small and large intestine.

Organs of the human body

The brain: the primary control and control center of the body.

Heart: it is a blood pump that delivers food and oxygen to all parts of the body and transports waste and carbon dioxide through the micro and major circulation.

Lungs: they supply the body with oxygen and expel carbon dioxide through the process of inhaling and exhaling.

Liver: works to rid the body of toxins, produce proteins important for blood clotting, filtering and purifying blood.

kidney: work to purify the human body of excess fluid and waste products





Respiratory system

The nose, pharynx, larynx, trachea and bronchi work together, a system of tubes through which air is directed to the lungs, in which there are very small air sacs called alveoli, which serve to introduce oxygen into the bloodstream and carbon dioxide from the blood is pushed into the air.


When an error occurs in a part of the respiratory system, such as an infection like pneumonia, it makes it difficult for them to get the oxygen we need and get rid of carbon dioxide resulting. Common respiratory symptoms include shortness of breath, cough and chest pain.


Respiratory parts

Nose and sinuses: it is a cavity that contains cartilage, muscles, bones and skin, is an important organ in the process of breathing by entering oxygen and expelling carbon dioxide in the body. The nose contains mucous membranes that moisten the air entering through it, as well as hair-like cilia that purify and filter the air entering the lung. The nasal sinuses also have a role in the process of pronunciation and letter exits and work to regulate the temperature of the air entering the lungs so that the air entering is neither cold nor hot and has a role in the balance of the body.

Pharynx: it is a muscular tube that is an important part of the respiratory and digestive systems, because it is considered a connecting point between the two organs, where the pharynx can be divided into three sections, namely the nasopharynx, oropharynx and laryngeal pharynx.

Larynx: the short part of the respiratory system that connects the laryngeal pharynx and trachea, and the larynx has an important role in the formation of sound in speaking or singing through the V-shaped vocal cords that are in tune with the movement of the air exit. The speed of the vibration or tension of those chords affects a change in the tone of the voice.

Trachea: it is part of the respiratory system and is a long muscular tube connecting the trachea hole and the lung, it has an important role in the process of gas exchange between the internal lung tissue.

Bronchioles and bronchioles: these are passages that allow air to enter the lungs, branching into two right branches that are wider and shorter than the left ones that are narrower and longer.

Lungs: a pair of air-filled spongy organs located inside the rib cage, where the right lung is made up of three parts and the left lung is made up of two parts, the lungs work to exchange gases between the alveoli by taking oxygen and expelling carbon dioxide.

Alveoli: it is a spherical, oxygen-carrying vesicle that performs all gas exchange processes within the lungs.
