Our body is being controlled by the central nervous system. The body is made up of many systems that all work together, and each system has an important function, but all of these systems are controlled by this one nervous system. Imagine how important that one system must be when you consider that it controls all of the other bodily systems.
For instance, let’s first consider the circulatory system made up of the cardiovascular or vascular system and the lymphatic system. This system’s primary job is to circulate our blood and by circulating that blood it carries oxygen and nutrients to and waste materials away from all of our body’s tissues. That same blood being circulated by the heart carries filtered blood plasma between blood cells as lymph.
Next let’s take a look at the respiratory system, which helps our body to breathe via our lungs. This system is made up of the trachea, bronchi, bronchioles, lungs and diaphragm. Each of these organs must work properly for us to breathe. Without this system working properly there would be no oxygen to be carried by the cardiovascular system.
Another important system is our immune system. To function properly the immune system must recognize and detect a wide variety of foreign invaders, also known as pathogens. This can range from viruses or bacteria to parasitic worms, and distinguish them from our own healthy tissue or non-harmful invaders. An improperly functioning nervous system is the cause of most allergies including seasonal allergies, respiratory allergies and food allergies.
Finally, let’s consider the digestive system. As much as we don’t want to talk about it, it’s probably the most important system in the body. This system is made up of a group of organs that work together to convert food into energy and the basic nutrients we need to fuel our body. The alimentary canal begins with the oral cavity, includes the pharynx, travels the esophagus, empties into the stomach then proceeds to the small then large intestines. Through this process, the body produces hormones and enzymes to help digest these foods and get the most from the nutrients included. Accessory organs that make up the digestive system include the teeth, tongue, salivary glands, liver, gallbladder and pancreas. Once all of these organs have done their job, the kidneys get involved in eliminating waste.
This is just the tip of the proverbial iceberg; there are so many more systems not yet considered: the endocrine system that controls all of our hormones; the integumentary system or exocrine system that controls the skin, hair, nails, sweat and more; the muscular and skeletal systems that enables the body to move and supports the organs; and the reproductive system that makes it possible to procreate.
