Someone from the community is currently working feverishly to complete this textbook answer. Remember me. Forgot your password? Answer The human anatomy has much resemblance to the complexity of a Russian doll; there are layers within the shell of one system, and yet correspondence that brings all systems together to function as one synchronous living organism, comprised of the following networks: Nervous System: Responsible for the perception and transport of external stimuli to various nerves, followed by the dorsal horn and gray matter, before reaching the brain where information from stimulus becomes conscious awareness.
The nervous system has 3 main parts-- the brain,spinal cord and neurons Musculoskeletal System Attached to the skeletal system, this system revolves around physiological movement of the body. In addition, this system supports, and stabilizes the body as a whole; it also protections various organs, such as the heart, and lungs which are protected by the rib cage.

In addition, the liver and large or small intestines, are protected by abdominal muscles. Circulatory System This system is responsible for transporting nutrients and oxygen in the blood for circulation to all bodily tissues, organs and muscles.
It is vital for proper tissue perfusion, respiratory function, renal function, and liver metabolism. Respiratory System The respiratory system is responsible for proper hemoglobin maintenance in blood cells, oxygenation in the bloodstream and bodily organs.

Oxygen and other gases of the inhaled air are delivered to the alveoli in the lungs, where diffusion takes place — allowing the blood to pick up the oxygen through diffusion to be deliver to the rest of the body.
Carbon dioxide is also off-loaded and and removed in exhaled ais Digestive System This system responsible for breaking down chemically complex food substances into simpler nutrient molecules that can be absorbed by the gastrointestinal system and delivered to the rest of the body.
Additionally, it is responsible for the metabolism of organic matter and excretion of fecal waste. Integumentary System This system is skin — the epidermis most outermost layer of skin, in contact with the environment , the dermis, subcutaneous fatty tissue and integumentary glands --sweat glands and sebaceous glands.
These all comprise the most peripheral body system charged with protecting the body and all of its inner contents. This system through neural receptors also keeps us aware of changes in the external environment. Furthermore, it is an important part of our innate defense system against pathogens and other potentially injurious entities that we come into contact with in our environment every day.
Urinary System This system is responsible for the filtration of blood and excretion of toxic substances and excess bodily fluids.

Reproductive system This system comprises the organs of reproduction and associated glands --male and or female; the female reproductive system is different from that of the male. This system produces reproductive cells --sperms and eggs--unite them in fertilization ad ensure their development into viable offsprings, The differentiation and development of secondary sexual characteristics are also important functions of the reproductive system hormones Lymphatic system Some people speak of the lymphatic-immune system , but the two systems are not identical.
Nonetheless, the lymphatic system has some immune functions. The vessels of the lymphatic system include lacteals.

The major structures are the bone marrow, the lymph nodes, the spleen and the thymus. The lymphatic system works to fight against infection, and illness through the employment of white blood cells, including neutrophils, monocytes and lymphocytes In addition the numerous lymph nodes all over the body, aid in fighting an invaders-- cells, toxins, organisms-- that have entered a body.
While components of the lymphatic system fuction in fat absorption and immune defence , another very important function of the lymphatic system is to return excess interstitial fluid ISF from the interstitial spaces ISS to the blood circulatory system.
This is necessary for maintenance of normal blood volume and blood pressure Endocrine system This system involved the circulation and maintenance and secretion of hormones throughout the body and to the intended organ. It comprises ductless endocrine gland of internal secretion that release their secretions into the blood. Some examples of endocrine glands are hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, pancreatic islets, adrenals, ovaries and testes.
Work Step by Step As a current nursing student, I have become well-educated in the anatomy and physiology of the human body, and how the associated physiological processes function as a series of chemicals reactions that reflect the state of one's body, and current health; I have also learned how these processes promotes future optimal health, and homeostasis of internal environment of the body.
This answers has been assembled through the knowledge and experience I have acquired as a registered nurse student in the New York City region. All of these body systems work together to maintain homeostasis- the condition of balance in body processes and conditions. For example, when one eats a piece of fruit or vegetable --or any food one eats-- it moves through the digestive system where various enzymes promote catabolism of the complex food chemicals into the simpler nutrient molecules like glucose and fatty acids.

The simple nutrients are transported by the circulatory system to tissues of other systems , such as the nervous, and respiratory systems. The nourishment enables the other systems to function normally so we are able to breathe respiratory system , feel nervous system , move musculoskeletal system , excrete urinary system and defend our internal environment integumentary and immune systems.
Chapter 3 The Cellular Level of Organization
The endocrine and reproductive systems that are so important for production and growth of offspring are also dependent on nutrition and respiration.
Most important of all for our functions as human beings are the processes of the central nervous system, especially those of the cerebral cortex. These are the processes that make us human.
They, also, depend on the balanced, normal working of the other physiological processes of the body. We really are what we eat, for what we eat builds and sustains the body, and the proper working of the body sustains mind and soul; in other words, there is a mind-body connection.
