Our humanbody consist of 11 main separate yet closely interconnected systems; namely,the Skeletal, Muscular, Circulatory, Respiratory, Digestive, Excretory,Nervous, Integumentary, Immune, Endocrine and Reproductive Systems. These work togetherto perform different functions and to make a complete functional organismFirstly, the significance of the skeletal system is its vital structuralpurpose to the human body. In addition the skeletal system stores minerals,produces blood cells and provides protection for delicate organs.
The systemsconsists of 206 bones are joined through with ligaments, tendons, withcartilage, a softer cushion like material, providing protection in jointedareas and muscles- linking to the muscular system . Moreover, the musclecompletely aid movements and are controlled by the muscular system, with thesemuscles being connected to bones. Nevertheless, the basis for those movementsis rooted in stimulation proved by nervous system. The nervous system causescontraction and the resulting movement of bones to which they are attached.
Inaddition, key involuntary muscles uphold the respiratory and circulatorysystems, by consistently providing contraction of the heart and lungs. The circulatorysystem’s main organ is the heart. The heart is so vital as is essentially pumpsblood through arteries, veins and capillaries. Furthermore, notably circulatorysystems is important ; the nutrients andoxygen to cells and waste products are removed hence aiding the immune systemthrough the circulation of white blood cells the circulatory system isresponsible for delivering. The immune system main role is to stop the bodyfrom being corrupted or attacked with pathogens.
Key components are lymphorgans, such as the spleen and thymus, and the skin, all of which areresponsible for protecting the body against invading pathogens Furthermore, the relationship of circulatory system and the respiratorysystem is close also. The respiratory system brings oxygen from the surroundingair into the body through the alveoli of the lungs. This also links closely to excretorysystem. It is tasked for the removal of waste gases (i.

e. CO2) throughexhalation. Ultimately this eliminates both solid and liquid wastes. Moreover, gaseousproducts, and is made up of a number of specialist tissues along with thebladder, large intestine, rectum, kidney, lungs. The digestive system is solelytasked with the physical and chemical breakdown of food. This journey starts inthe mouth- physical breakdown as well as salivary (chemical) breakdown, then travelsthrough the oesophagus to the stomach (stomach muscles aid in physicalbreakdown, while acid {HCL}), and small intestine for digestion. Additionally,production of digestive enzymes and bile in the liver, pancreas and largeintestine are also involved, through the and the processing nourishment (nutrients)for the body.The role of nervous system is delivering impulses the brain through neurons.
The bodies movement and functions are fuelled by electrochemical signalsthrough the neural network all playing key role in the nervous system .The waythe nervous system intercepts’ with endocrine system, is through communication network however utilisinghormones as chemical signals which travel through the blood . Hormones specificallytarget organs and carry signals to start or stop performs functions. As aresult, the reproductive system produces of children and reproductive hormonescause our bodies to develop into sexual maturity.
