Fainting Definition Fainting is a generally brief and unexpected loss of consciousness from a lack of blood flow to the brain followed by the return to full wakefulness (Appendix A) . This loss of consciousness is accompanied by loss of muscle tone that can result in falling or slumping over. Cause of fainting There are so many causes of fainting‚ which makes identifying cause difficult at times. Some common causes are extreme emotional stress‚ too little food or drink resulting in low blood

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to

The many processes by which the body controls its internal environment are collectively called homeostasis. The complementary activity of major body systems maintains homeostasis. Homeostasis is the maintenance of a constant internal environment. It is involved in many bodily functions‚ such as keeping the body’s internal environment constant much like the thermostat of a central heating system. Homeostasis keeps the body’s temperature at a certain level and it keeps the pH of the body at a certain

Homeostasis What is it? Maintenance of a relatively constant internal environment The human body is constantly responding to internal and external factors in order to maintain relative stability within the body Homeostasis is vital to the body as a whole‚ right down to each individual cell. If homeostasis is not maintained at the cellular level this will affect the body as a whole. History Claude Bernard (1813-1878): consistency of internal environment is the condition for free life.

Homeostasis A condition in which the internal environment of the body remains relatively constant despite changes in the external environment. Examples would be the maintenance of body temperature and levels of glucose in the blood Homeostatic mechanisms are designed to reestablish homeostasis when there is an imbalance. The Home Heating System 1. When the temperature of a room decreases below a set point‚ the thermostat electrically starts the furnace. 2. As the temperature of the room rises to

Homeostasis maintains the body’s internal environment it allows organs and cells to function at their best. It keeps the body at steady state‚ this refers to the fact that conditions need to remain constant‚ if not then normal function would be disrupted. However there is a certain limit set ‚ this is due to the changing values ‚ rather they are maintained around an ideal value which is also known as the set point. The skin regulates most of the body temperature and uses a mechanism called negative

Homeostasis‚ also spelled homoeostasis (from Greek: ὅμοιος‚ "hómoios"‚ "similar")‚ is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a process that maintains the stability of the human body’s internal environment in response to changes in external conditions. The concept was described by Claude Bernard

Homeostasis The conditions inside our body must be very carefully controlled if the body is to function effectively. Homeostasis is the maintenance of a constant internal environment. The nervous system and hormones are responsible for this. One example of homeostasis is the concentration of carbon dioxide in the blood being carefully controlled. Here are some of the other internal conditions that are regulated: Body temperature This is controlled to maintain the temperature at which the
