The Homeostatic Feedback System

Homeostatic Imbalance: Respiratory and Skeletal Systems Homeostasis is an important part of the body and helps to keep regulation going within the systems. When learning about homeostasis, there are two different feedback systems that take place and play major roles in the human anatomy. “The feedback systems disrupt homeostasis by increasing or decreasing a controlled condition” (Tortora & Derrickson, 2014). These are the positive feedback system and the negative feedback system. “The positive feedback system tends to strengthen or reinforce a change in one of the body’s controlled conditions. In a positive feedback system, the response affects the controlled condition differently than in a negative feedback system. The control center still

The action of a positive feedback system continues until it is interrupted by some mechanism” (Tortora & Derrickson, 2014). Unlike the positive feedback system, the negative system works the opposite in contrast. “The negative feedback system reverses a change in a controlled condition” (Tortora & Derrickson, 2014). There are many systems within the body that are affected by homeostatic imbalance. One system that has both positive and negative feedback systems is the respiratory system. The respiratory system has positive feedback by the body helping oxygen pass through the lungs and bloodstream. With oxygen coursing through the body, it makes its way through the bloodstream, helping the blood vessels flow through the body to each area in which they need to travel. “Your body’s cells continually use oxygen (O2) for the metabolic reactions that release energy from nutrient molecules and produce ATP. At the same time, these reactions release carbon dioxide (CO2)” (Tortora & Derrickson, 2014). Though there are some who suffer from respiratory medical issues such as asthma and chronic obstructive pulmonary disease (COPD). “Asthma and chronic obstructive

It is important that the skeletal system maintain homeostasis so that the system does not weaken and does not deteriorate causing the other systems to begin to weaken or fail. The skeletal system maintains homeostasis by making sure the calcium levels within the bones are where they should be in order to be considered healthy. If the balance is off, there are risks of bone deterioration and injury such as fractures or calcium deficiency. If these occur, there are different treatments that can be given. The first is physical therapy such as exercise in order to strengthen the bones. Another form of treatment is medication such as Vitamin D supplements or hormones such as parathyroid hormone (PTH) to help the extracellular fluid stay balanced. “Drugs with easy application and low frequency of dosing are associated with a higher adherence. Increase of therapeutic adherence in real-life medicine is an important clinical goal, especially in the treatment of osteoporosis” (Tomková, Telepková, Vaňuga, Killinger, Šulková, Celec & Payer, 2014). It is highly important to keep the calcium intake to the recommended level in order to keep a balance. “Calcium in the diet is required to sustain bone density. Its absorption is affected by vitamin D, phytates in the diet, as well as other nutrients (phosphorus, sodium and protein). Dietary interventions primarily focus on increasing dietary calcium”
