Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration.\n\nFunction\nIn mammals\nIn most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face; on most other mammals, it is on the upper tip of the snout.\n\nAs an interface between the body and the external world, the nose and associated structures frequently perform additional functions concerned with conditioning entering air (for instance, by warming and/or humidifying it) and by mostly reclaiming moisture from the air before it is exhaled (as occurs most efficiently in camels).\n\nIn most mammals, the nose is the primary organ for smelling. As the animal sniffs, the air flows through the nose and over structures called turbinates in the nasal cavity. The turbulence caused by this disruption slows the air and directs it toward the olfactory epithelium. At the surface of the olfactory epithelium, odor molecules carried by the air contact olfactory receptor neurons which transduce the features of the molecule into electrical impulses in the brain.\n\nIn cetaceans, the nose has been reduced to the nostrils, which have migrated to the top of the head, producing a more streamlined body shape and the ability to breathe while mostly submerged. Conversely, the elephant's nose has become elaborated into a long, muscular, manipulative organ called the trunk.\n\nHuman nose\nThe visible part of the human nose is the protruding part of the face that bears the nostrils. The shape of the nose is determined by the ethmoid bone and the nasal septum, which consists mostly of cartilage and which separates the nostrils.\n\nYou could get more information from the link below...

THE FIVE MAJOR FUCTIONS OF THE SKELETAL SYSTEM\n1st:The skeleton gives shape and support to your body\n2nd:bones protect your internal organs.For example,ribs surround the heart and lungs, and the skull encloses the brain.\n3nd:Major muscles are attached to bone and help them move\n4th:Blood cells are formed in the center of many bones in soft tissue called red marrow.\n5th:Major quantities of calcium and phosphorous compounds are stored in the skeleton for later use.Calcium and phosphorous make bones hard.

The lungs (respiratory system) take in air (using the oxygen and breathing out the carbon dioxide), the heart pumps the oxygen through our arteries (circulatory system)making our blood red.

The respiratory system starts with the nose and mouth where we breathe in oxygen and expel carbon dioxide. The oxygen travels down the windpipe(trachea) and into the bronchi contained in each lung. The windpipe splits into two bronchi which go into each lung. Each bronchi spreads into smaller structures called bronchioles. These spread through each of the lungs. Each bronchiole has a number of smaller structures known as alveoli. The alveoli have a very large surface area and is where gas exchange occurs. Oxygen replaces carbon dioxide and is taken to all parts of the body via the bloodstream. Carbon dioxide is toxic to humans in high concentrations which is why it is breathed out. \nThe main structures are nose, mouth, windpipe, lungs, bronchi, bronchioles, alveoli.

That's spelled "respiratory" system, not "respitory" ;-)\n\nYou'll find an explanation of how your respiratory system works here:\n\nhttp://sln.fi.edu/biosci/systems/respiration.html\nor here: http://yucky.discovery.com/flash/body/pg000138.html\nor a slightly more technical explanation here: http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/P/Pulmonary.html

into mouth or lungs, through pharynx, into bronchioles and then bronchioli, then into each lung to a sac of alveoli, then onto hemoglobin molecules in blood cells, then to the heart to be pumped to the body and given to a body cell.

this may not be the answer you are looking for... but here it is anyway...\n\nthe respiratory system involves providing oxygen for the body. You inhale air which is made of different gases and your lungs absorb oxygen out of the air and you exhale the stuff that isn't absorbed. Oxygen is needed for burning fuel. Every single cell (trillions of them) need this oxygen you just inhaled. How does it get to every single blood vessel? you guessed it! the Circulatory system \n\n... the oxygen rich blood goes to the heart. .. and with every beat gets pumped out in all different directions all over the place and then once the oxygen has been delivered, the spent blood comes back for a refill... this happens many many times per minute. \n\nnow, all this blood would go nowhere without a heart. What is a heart essentially? a big strong muscle that goes and goes and goes for 80 years or more without ever stopping! in addition to this, every move you make, helps blood flow. especially walking, your feet act like mini pumps cuz you step on one foot the blood gets pushed around and then you step on the otehr foot as you walk and it goes on. \n\nAnd of course the nervous system. This has instructions directly form mission control ... your brain. It controls your heart speed, breathing speed, blood flow to different parts of the body depending on which part needs how much at what time and everything. None of these systems could normally work without the other one ... but if your nervous system goes down, your pretty much a vegetable. \n\nI know I just explained what all these different systems do but hopefully it helps you understand better.
