Three Specific Body Systems that are Necessary for Life

    The nervous system is very important to the human body and it is necessary for life. The functions of the nervous system are the Sensory function, Integrative function, and the Motor function. The Sensory function gathers information when changes occur within and around the human body. The Integrative function is where “information is brought together,” like it makes decisions, creates sensations, creates thoughts, and adds to your memory in the human body. Last, the Motor function responds to signals. Without the nervous system, we as a human wouldn’t have our sense of smell, taste, hear, vision, or touch. That is why the nervous system is necessary for life.

        The Sensory system is important and necessary for life. This system has most of all the body traits we need. There is the sense of smell, sense of taste, sense of hearing, the sense of equilibrium, and sense of touch. Every human needs these senses in life. Without these senses working, the human life wouldn’t be necessary because we all need senses for the human body otherwise how would we live without senses. All humans need to see, touch, hear, taste, and to have the sense of equilibrium.

       The Endocrine system is very important to the human body and it is necessary for life. If it wasn’t for the Endocrine system then we wouldn’t have the Pituitary gland, which releases hormones like when you have puberty, the thyroid gland, which controls your metabolism, the parathyroid gland, where four tiny glands help maintain calcium and phosphorous levels. Then, you have the Adrenal gland, which produces adrenaline in the human body and the pancreas that is to keep the blood sugar levels healthy. Without all of these particular glands, then the human body won’t be able to change from puberty, the metabolism won’t be controlled, there wouldn’t be calcium and phosphorous levels, the blood sugar levels would be unhealthy, and lastly the adrenaline rushes that the human has won’t be there. So, my point is this is a system that is necessary for the human body. These are all important systems that are very necessary to have for the human body.
