Answer: It is called the Cellular Level of Organazation and it ranges from (Atoms, Molecuels,Cells, Tissue, Oragans ,Oragan System and Oraganism). There are ten Oragn systems (Digestive, Integumentary,Bone) for examples. An organ system is a group of cells that make up tissue, that make up an organ like the brain or heart. The Brains organ sytem is called the Central Nervous System (CNS), and the heart is apart of the Respiratory System. So the answer to your question is "Yes" an organ system is more complex compared to an organ. The organ system can explain the function of an organ. Whats a stomach without the intestines and the colon together these three organs make up the Digestive System. Organ systems are simply made up of some organ.
Answer: INTERACTING WITH OTHER SYSTEMSThe excretory system is a close partner with both the circulatory and endocrine system. The circulatory system connection is obvious. Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.
The endocrine system is the major controller of the excretory system. As levels of compounds and fluids are monitored, kidney function must be constantly altered to provide the best internal environment for your cells. If you drink too much water, hormones are released that allow for more urine production. If you are dehydrated, less urine will be produced. The kidneys are also tied to the endocrine system with the adrenal gland position on the top of each kidney. The adrenals release adrenaline into your body skin,lungs,kidney circulatory system and the respiratory system works with the excretory system ALL of the body systems work together. The organs that are involved with excretion are in differentsystems of the body. The systems containing these organs are theintegumentary, gastrointestinal, respiratory, and urinary. cirulatory and respitory system
Answer: When the appendix (a blind-ended tube connected to the cecum)becomes inflamed, unless treated or surgically removed, theresulting infection can cause death. In humans, the appendix is assmall as your little finger, and is no longer needed.
Answer: Brain cancer by itself can affect nearly all organ systems in the body because its responsible for innervating every single organ and organ systems in the body, nut the mostly affected systems are the nervous system which it is a part of and the musculo-skeletal system, this if its not metastasised. sometimes brain cancer metastasise to other organs , which accordingly will affect.
Answer: Aids & cancer This usually depends on which organs it affects. You could safelysay it in two categories, communicable and non-communicablediseases. Examples are the common Heart dieseases, Diabetes,Cancer, Tuberculosis, Anemia and the like.
Answer: You could get hit in the head with a object or trauma by hitting head on something you could also be subjected to chemical or other odorless smoke or breath anything that would cause it then this stuff goes in the brain it also can be hereditary in the genes it has little tentacles that wrap around veins as it grows.
Answer: There are many different causes of cancer and having a certain gene will not definitely mean that you develop the disease. Only around 5-10 per cent of cancers are thought to be caused by faulty inherited genes.read more about cancer at http://cancerlinks.blogspot.com/
