Homeostasis Writing Prompt

Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

“Homeostasis in a general sense refers to stability or balance in a system. It is the body's attempt to maintain a constant internal environment. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change” (Human Physiology/Homeostasis, 2016). Negative feedback will operate to return Mrs. Loiselle’s body back to homeostasis in such a way her body, system responds in which it reverse the direction of changes. Since negative feedback tends to keep things constant, it allows the maintenance of homeostasis. As Mrs. Loiselle’s fainted by going for the run without eating something from last evening that made her week and she lost an enormous amount of energy in her exercise through sweating continuously. That made her dehydrated and because

1. Compare and contrast how positive and negative feedback mechanisms are used to maintain homeostasis. Use these concepts to describe:

According to Model 3, what is the stimulus and what is the response during childbirth?

Homeostasis is the process of maintaining a fairly constant interval environment. Homeostatic mechanisms help us to be independent of our external environment. It helps us regulate our body temperature, pH, concentration of dissolved substance in the body fluids, concentration of glucose in blood, concentration of oxygen and carbon dioxide in the blood and body fluids, blood pressure and concentration of metabolic wastes. Without it, we wouldn’t be able to survive and adapt to our environment.

Homeostasis is a biological process that maintains a constant internal environment, regardless of what is going on in the external environment. This process ensures the bodily functions and chemicals are kept in a state of balance which in return allows the body to function optimally. Homeostasis requires coordination of the hormonal (endocrine system) and nervous systems, which together regulate the activity of the body’s organ systems. The regulatory activities are constantly adjusted in response to stimuli (change) from both the internal and external environment. A change influenced by the external environment can cause a state in the body that will take it away from the normal, the body will act to counteract this change and return the internal environment back to a steady state. This is negative feedback. Negative feedback has a stabilising effect reducing changes from a set point and returning internal conditions to a steady state. Most body systems e.g. controlling blood glucose levels, obtains homeostasis through negative feedback which makes the negative feedback system critically important in obtaining homeostasis. However there is also positive feedback which is a system that results in the escalation of a response to a stimulus. It causes instability in the system and is used when there is a specific outcome required. Positive feedback ceases once the natural resolution is reached e.g. baby is born, pathogen is destroyed, blood clot forms. This system is not used

All living things strive towards one goal: homeostasis. Homeostasis is a state of equilibrium reached through physiological processes. In order to maintain homeostasis, living things use cells, tissues, organs, and organ systems to counteract physical changes. Using a variety of different tissues, organs are formed to accomplish specific tasks. The four main types of tissues are epithelial tissue, connective tissue, muscular tissue, and nervous tissue. Several sublevels exist for each type of tissue.

The body can regulate its internal environment through feedback systems. A feedback system is a cycle of events in which the condition of the body is monitored, changed, re-monitored and re-evaluated. Each monitored variable such as temperature, blood glucose and blood pressure is termed as a controlled condition. Any disruption that changes a controlled condition is called a stimulus. Only three components make up the feed back system - a receptor, a control center and an effecter.

Tony I need you in the lab ASAP, and bring the vita radiation device with you.-Bruce’s voice sounded agitated.

Homeostasis regulates many body processes such us temperature, water balance and salt concentration. In this scenario the change from warm to cold weather stimulates homeostasis environment of the body and the receptors which maintain the temperature in the body, which prompts a message to the control center, the hypothalamus which it is where the process that controls body temperatures occurs. This message initiates changes to the effectors carrying the response to cold temperature. Vasoconstriction occurs and blood flow increases to keep heat deep in to the body and muscles tighten causing the hair to stand up creating a protected layer of air to maintain the body warm.

Homeostasis is the stoppage of bleeding or hemorrhage. Homeostasis bleeding can also referred to the stoppage flow through the body or the organs. During homeostasis the vessel was close and become constricted. The word homeostasis comes from the Greek root heme meaning blood, stasis meaning to halt. You can apply thrombin to release the vessels. Other mechanisms that form from homeostasis are vasoconstriction, platelet plug formation and clotting of the blood.

The homeostatic response is the equilibrium between the inside of the body and its external extremities. Exercise affects the body temperature, blood oxygen levels, sugar levels and hydration, it is vital for the body to maintain homeostasis. Without exercise the body maintains homeostasis by eating and drinking correctly. However, during exercise the body needs to have a constant supply of oxygen to the cells to support the moving muscles, “During exercise, your body needs to maintain a constant supply of oxygen in your cells to support your working muscles, which might need 15 to 25 times more oxygen than when they are resting” (Fisk, 2015). Due to this, the breathing rate increases, and keeps increasing the harder the body is being pushed.

Homeostasis is important to the function of enzymes because it maintains these things called enzymes. It maintains them through the signals that the brain gives off. If enzymes aren’t taken care of they will die because enzymes are used in the chemical reactions which helps connect the compounds.

Homeostasis uses a feedback mechanism called negative feedback meaning that it works from feedback it receives about changes that need to be made. The mechanism responds to the normal range of environmental factors because the receptors sense that a change needs to be
