more than a few minutes if the blood pH drops or rise from the normal blood pH. If the blood pH is not in the normal blood pH‚ the person can fall sick and it might be harm to the person. The maintenance of blood pH is called acid-base homeostasis. Acid-base homeostasis is a complex synergy that involving lungs‚ kidneys and a buffer chemical in blood and blood cells. BACKGROUND A substance that has high concentration of hydrogen ion in solution is called acid and solution that has low concentration

There are two forms of homeostasis‚ positive feedback and negative feedback. The type of feedback which is most common is negative feedback. This works by making the levels that have changed return back to normal. Positive feedback is the least common type of feedback. This is where one component escalates to another which continues to escalate to another. In positive feedback the level of control the component does not return to normal straight away. Negative feedback is usually what happens inside

Anatomy and Physiology P5/M2 - Homeostasis Homeostasis is the need for an organism or a cell to regulate its internal environment (conditions within the fluid surrounding its body cells) by a system of feedback controls to stabilise health and functioning despite the outside changing conditions. This is important as this is what maintains and helps internal conditions (body temperature) to remain stable and constant. In humans homeostasis happens when the body regulates its body temperature in

Pernicious Anemia and its association to orthostatic hypertension Pernicious anemia is the major form of vitamin B12 deficiency. It is caused by serum antibodies against intrinsic factor which leads to B12 deficiency rather than by B12 deficiency itself. Absorption of vitamin B12 requires intrinsic factor which is secreted by parietal cells. Pernicious anemia is marked by autoimmune attack on gastric mucosa and a loss in parietal cells. Approximately 75% of the affected patients have type I antibody

Essay Describe and evaluate the synaptic homeostasis model of sleep The synaptic homeostasis model of sleep (Tononi & Cirelli‚ 2003) explains memory consolidation as a by-product of synaptic downscaling that occurs during sleep. This essay will describe the synaptic homeostasis model of sleep and evaluate how valid its predictions are in the face of empirical research. According to this model‚ synaptic potentiation is associated with the homeostatic regulation of slow wave activity‚ which

The importance of homeostasis can be seen in blood pressure and pulse rate‚ as measurements which are

How well do the concepts of drive and homeostasis contribute to understanding sexual motivation? Both sexual motivation‚ hunger and thirst are biological motivations‚ a desire that directs behaviour (Myers‚ 2004‚ p. 420). However unlike sexual motivation which drives us to pleasure and procreation‚ hunger and thirst are needed to survive. In regards to the motivation behind hunger‚ drive reduction theory suggests that the bodys motivation to maintain homeostasis drives us to reduce our need for hunger

10 Ways my Body Maintained Homeostasis By Travis Bushong 1. I was sweating after jogging a mile because my body’s internal temperature had gotten too high and I needed to cool down so my body used the extra internal heat to release sweat and at the same time keep homeostasis. The systems involved were my nervous system and my integumentary system. 2. When I was shivering after getting out of the hot tub it was my muscles moving quickly. Muscles need a combination of fats and sugars burned with

1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”
