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 of hydrogen ion is base. Base

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood

------------------------------------------------- Water and Electrolytes Water constitutes 50-55% of a woman’s body weight and 55-60% of man’s weight. Water gives structure and form to the body‚ helps maintain body temperature‚ and also creates the necessary environment for cell metabolism. There are two compartments of body water‚ extracellular and intracellular fluid. Extracellular fluid (ECF) is water found outside of cells. Making up approximately 20% of total body weight‚ the ECF consists of blood plasma‚ interstitial fluid surrounding

Did the pH level of the blood change at all during normal breathing? If so‚ how? No 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No Activity 2a: Hyperventilation – Run 1 1. At 20
