Homeostasis

=Homeostasis- The body's internal constancy=

In order for internal constancy to be maintained, your body must have sensors that are able to detect deviations. Sensors detect changes from homeostasis or a set point. When the sensor detects a difference in the body it will send a message to the integrating center to make a change.

This is a cool video that show how your body can become insulin resistant.

The negative feedback loop of insulin is as follows. When you eat you increase the amount of glucose (SENSOR) in your body, this tells (INTEGRATING CENTER) your pancreas to create insulin which assists in the (EFFECTOR) uptake of glucose which will lower your blood glucose.

It is important that insulin and other molecules be regulated because if they are not functioning correctly it will cause disease such as diabetes. It is important that they body stay at a constant because that is where it is meant to work more efficiently and a healthy body is able to regulate the changes on it's own.

Review of Chapter
processes.
 * Human Physiology**- is the study of functions and activities of living organisms and their parts, including all physical and chemical

The components of Scientific Method are: 1. Form a testable hypothesis 2. Conduct and analyze experiments to test the hypothesis 3. Decide rather the results support or disprove the hypothesis 4. Develop a theory
 * Scientific Method**- a method of research in which a problem is identified, data is gathered, a hypothesis is formulated from this data, and the hypothesis is tested.

Homeostasis- is maintenance of a state of dynamic constancy, in which conditions are stabilized above and below a physiological set point- This is done by negative feedback loops.

A negative feedback loop consists of a SENSOR- the sensor is the nerve that detects the change in the body. This then sends a message to the INTEGRATING CENTER- which will determine the body's response that is needed- Next the integrating center sends a message with the EFFECTOR- which produces the needed response.

There are also POSITIVE FEEDBACK LOOPS- these are rare because in this situation the response is magnified. It is involved in producing blood clots, causes the LH surge, which causes ovulation in females, and assists functions during labor.

__**Personal Application of Information**__ How homeostasis effects me in everyday life is that these functions are continuously taking place to regulate our bodies. When I am cold I shiver or when I am working out at the gym how my body will increase blood pressure and oxygen to compensate for the changes in my body. This is very important when working with clients that have extremely high blood pressure or have a heart condition that their blood pressure needs to stay within a certain number. In order to protect the patients health and ensure the patient is exercising within his health limits we must understand how to regulate the body. I will use this information to give accurate treatment for my patients in my career.

Chapter one also covered the different types of tissue, organs, and systems.
