Anatomy Of Human

A Brief record of the Eleven Major Organ Systems in the Body and Their Main Function

1. Integumentary - This law includes the skin and its appendages (hair, nails, and specialized sweat- and oil-producing glands). Its traditional function is protection. For example, the skin protects the basal tissue from invasion by harmful bacteria, bars entry of most chemicals, and minimizes the chances of mechanical injury to basal structures.

2. Skeletal - The skeletal law includes bones and related tissues such as cartilage and ligaments, which furnish the body with a rigid framework for maintain and protection. The skeletal law also makes potential the movements of body parts.

3. Muscular - The muscular system, consisting of the private skeletal muscles, makes movement potential and generates the heat required for maintaining a constant core body temperature. Voluntary muscles are so called because their contractions are under known control. Involuntary or flat muscle tissue is found in blood vessel walls, other tubular structures and in the lining of hollow organs such as the stomach and small intestine. Cardiac muscle is the specialized muscle tissue of the heart.

4. Nervous - The nervous law is composed of the brain, spinal cord and nerves. The nervous law makes potential communication between body functions, integration and control of body functions, and recognition of sensory stimuli.

5. Endocrine - The endocrine law is composed of specialized glands that secrete chemicals known as hormones directly into the blood. The organs of the endocrine law are sometimes called ductless glands. The endocrine law is similar to the nervous law in that it also provides communication, integration and control, but it does it in a slower and longer-lasting way by hormone secretion. Hormones are also the main regulators of metabolism, pregnancy and other body activities. They play foremost roles in fluid and electrolyte balance, acid-base equilibrium and power metabolism.

6. Cardiovascular (Circulatory) - The cardiovascular law includes the heart, arteries, veins and capillaries. The traditional function of this law is transportation. communication needs comprise continuous movement of oxygen and carbon dioxide, nutrients, hormones, and other foremost substances. This law also helps regulate body temperature by distributing heat throughout the body and by assisting in retaining or releasing heat from the body by regulating blood flow near the body surface. Specialized cells of the circulatory law can also come to be complicated in immunity.

7. Lymphatic - The lymphatic law is composed of lymph nodes, lymphatic vessels and specialized lymphatic organs such as the tonsils, thymus and spleen. The lymph law moves fluids and inevitable large molecules from the tissue spaces around the cells and moves fat-related nutrients from the digestive tract back to the blood. It also plays a role in the functioning of the immune system, which is the defense mechanism of the body against disease.

8. Respiratory - The respiratory law includes the nose, pharynx, larynx, trachea, bronchi and lungs. Its traditional function is to permit the movement of air into the alveoli, which are the tiny thin-walled sacs of the lungs. In these sacs, oxygen from the air is exchanged for carbon dioxide, a waste product, which is then carried to the lungs by the blood so that it can be eliminated from the body. The respiratory law is also complicated in regulating the acid-base equilibrium of the body.

9. Digestive - The digestive law is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum and anal canal (primary organs), as well as the teeth, salivary glands, tongue, liver, gallbladder, pancreas and appendix (secondary organs). All of the organs of the digestive law work together to ensure proper digestion and absorption of nutrients.

10. Urinary - The urinary law includes kidneys, ureters, bladder and urethra. The traditional function of this law is the elimination of waste from the body. Other organs of the body are also complicated in the elimination of body wastes, such as the lungs and skin.

11. Reproductive (consisting of a male subdivision and a female subdivision) - The pregnancy law is composed of gonads (testes), vas deferens, prostate, penis and scrotum in the male, and gonads (ovaries), uterus, fallopian tubes, vagina and mammary glands in the female. The purpose of this law is the procreation of life, insuring survival of humankind.
