The Main Points
The respiratory system is one of the many systems in the human body. It's goal is to deliver oxygen (O2) to the blood so that the blood can deliver it to the rest of the body. The system also excretes carbon dioxide (CO2), it being a harmful gas for the human body. The respiratory system is mostly responsible or the life function respiration, hence the name, but it also partially completes the life function of excretion. Respiration is the take in of oxygen by a cell or an organism for life needs such as production of energy in cells. In cells it is called cellular respiration, and the mitochondria of each cell in the human body use the oxygen passed to them by the respiratory system to make energy in order to complete their duty. The oxygen is carried over by the blood flowing through the whole body that picks up new oxygen as it starts a cycle and then comes back with wastes. The process of excretion is the releasing of wastes from the body. The respiratory takes care of ridding the human body of CO2 by an opposite process compared to the consumption of O2.
The respiratory system, as all other systems of the human body help maintain homeostasis. This particular system helps to do so by bringing the levels of oxygen in the body that are necessary and removing wastes (carbon dioxide) that could disturb homeostasis. Homeostasis also requires body systems to work together and not to overload another body system with some sort of function. The respiratory works together most importantly with the circulatory system. The interaction between them is very important, since the respiratory supplies the oxygen for the circulatory that then circulates that oxygen through out the body and powers the body. The circulatory also returns the CO2 that's not needed and it is excreted through the respiratory system. Another system that the respiratory interacts with is the nervous system. Every system of the body must interact with the nervous system, since it commands the body what to do. In this case, th nervous system monitors the levels of carbon dioxide and oxygen in the body and tells the system when it is time for breathing in and when for breathing out. The respiratory system of course interacts with several other systems such as the muscular system.
