• Mutations in the ALDOB gene reduce the function of the enzyme, impairing the ability to metabolize fructose.

unit 5 P5- Explain the concept homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose.

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate.

3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you picked the choice that you did. How well did the results compare with your prediction?

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?

1.What are some of the advantages and disadvantages of the current health care system in the United States?

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.

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

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.

output in favour of maintaining organ function. The brain is a very energy costly organ, and so

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.

“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

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
