Many people today are interested in exercise as a way of improving their health and physical abilities. But there is also concern that too much exercise, or exercise that is not appropriate for certain individuals, may actually do more harm than good. Exercise has many short-term acute and long-term effects that the body must be capable of handling for the exercise to be beneficial. Some of the major acute effects of exercising are shown in Figure 1.
Alkalosis An important property of blood is its degree of acidity or alkalinity. The acidity or alkalinity of any solution, including blood, is indicated on the pH scale. The pH scale, ranges from 0 strongly acidic to 14 strongly basic or alkaline. Blood is normally slightly basic, with a normal pH range of 7.
Usually the body maintains the pH of blood close to 7. Blood acidity increases when the Level of acidic compounds in the body rises through increased intake or production, or decreased elimination Level of basic alkaline compounds in the body falls through decreased intake or production, or increased elimination Blood alkalinity increases when the level of acid in the body decreases or when the level of base increases.
These mechanisms involve the Lungs Buffer systems Role of the lungs One mechanism the body uses to control blood pH involves the release of carbon dioxide from the lungs.
Carbon dioxide, which is mildly acidic, is a waste product of the processing metabolism of oxygen and nutrients which all cells need and, as such, is constantly produced by cells. It then passes from the cells into the blood.
The blood carries carbon dioxide to the lungs, where it is exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases acidity increases. The brain regulates the amount of carbon dioxide that is exhaled by controlling the speed and depth of breathing ventilation.
The amount of carbon dioxide exhaled, and consequently the pH of the blood, increases as breathing becomes faster and deeper. By adjusting the speed and depth of breathing, the brain and lungs are able to regulate the blood pH minute by minute.
Role of the kidneys The kidneys are able to affect blood pH by excreting excess acids or bases. The kidneys have some ability to alter the amount of acid or base that is excreted, but because the kidneys make these adjustments more slowly than the lungs do, this compensation generally takes several days.
Buffer systems Yet another mechanism for controlling blood pH involves the use of chemical buffer systems, which guard against sudden shifts in acidity and alkalinity. These weak acids and bases exist in pairs that are in balance under normal pH conditions. The pH buffer systems work chemically to minimize changes in the pH of a solution by adjusting the proportion of acid and base.
The most important pH buffer system in the blood involves carbonic acid a weak acid formed from the carbon dioxide dissolved in blood and bicarbonate ions the corresponding weak base. Types of Acid-Base Disorders There are two abnormalities of acid-base balance.
The blood has too much acid or too little baseresulting in a decrease in blood pH. The blood has too much base or too little acidresulting in an increase in blood pH.
Acidosis and alkalosis are not diseases but rather are the result of a wide variety of disorders. The presence of acidosis or alkalosis provides an important clue to doctors that a serious problem exists. Types of acidosis and alkalosis Acidosis and alkalosis are categorized depending on their primary cause as Metabolic Respiratory Metabolic acidosis and metabolic alkalosis are caused by an imbalance in the production of acids or bases and their excretion by the kidneys.
Respiratory acidosis and respiratory alkalosis are caused by changes in carbon dioxide exhalation due to lung or breathing disorders.
People can have more than one acid-base disorder. Compensation for acid-base disorders Each acid-base disturbance provokes automatic compensatory mechanisms that push the blood pH back towards normal. In general, the respiratory system compensates for metabolic disturbances while metabolic mechanisms compensate for respiratory disturbances.Cost/LB: $ SAP Value: KOH NaOH Abyssinian Seed Oil is a highly stable oil that is regarded for its significant content of Erucic Acid, a monosaturated Omega-9 fatty acid known for its ability to act as a natural lubricant for massage, skin and hair care applications.

The list below is made according to order when they act: 1) Chemical buffering systems. Every acid in the body apart from carbonic acid is so called metabolic acid.
Most of us never consider the acid/alkaline balance of our blood, but a proper pH is a crucial aspect to overall health. Many doctors stress the importance of reducing acidity and increasing alkalinity with an alkaline diet because a balanced pH helps protect us from the inside out.
Disease and disorder, they say, cannot take root in a body whose pH is in balance. The Importance of Acid and Alkaline Balance for Health. Virtually all degenerative diseases including cancer, heart disease, arthritis, osteoporosis, kidney and gall stones, and tooth decay are associated with excess acidity in the body.
How Chemicals Are Exchanged in the Body. All cells in the body continually exchange chemicals (e.g.,nutrients, waste products, and ions) with the external fluid surrounding them (Figure 2).This external fluid, in turn, exchanges chemicals with the blood being pumped throughout the body.
The acid/base balance is expressed in terms of pH. An acidic environment has a pH of less than , whereas a basic or alkaline setting has a pH of greater than How Chemicals Are Exchanged in the Body.
