Homeostasis Of The Ph Levels

The practical was carried out to investigate the effect of pH on the reaction of the enzyme acid phosphatase.

Did the pH level of the blood change at all during normal breathing? If so, how?

A patient with poorly controlled Type I diabetes has blood drawn and finds that the pH of his blood is 7.1. The normal pH of blood is 7.4. The patient's blood [H+] is

The normal blood pH is between 7.35 and 7.45. Allen’s blood was acidotic due to a decrease in lung expansion and an alteration in the perfusion to his spinal cord. He also has an alteration in spinal innervation to the respiratory muscles including the phrenic nerve that controls the diaphragm. This would further cause Allen to not be able to adequately take in enough oxygen and blow off enough CO2 to adequately have gas exchange, within the alveoli. Respiratory failure.

3.An example of the urinary system working with the respiratory system to regulate blood pH would be

The base excess indicates the amount of excess or insufficient level of bicarbonate in the

the number of hydrogen ions in the blood, which decreases the pH of the blood. This is as a direct consequence

In this experiment different pH levels ranging from 3 to 11 were used to test the effects on daphnia heart rate. The pH scale ranges from 0 to 14. A pH ranging from 0 to 6 is acidic, a pH of 7 is neutral, and a pH higher than 7 ranging from 8 to 14 is basic. PH revolves around hydrogen ions (H+). The reason pH levels can be acidic, basic, or neutral is because acids give hydrogen ions away while bases accept hydrogen ions. (Decelles, 2002).

This is being done to provide the most comfortable conditions for a variety of biochemical reactions going on in these fluids, because "in order for a particular reaction to occur or to occur at an appropriate rate, the pH of the reaction medium must be controlled" (Biological buffers, n.d.). Human blood pH levels are kept in the narrow range from 7.35 to 7.45 to ensure that physiological processes go smoothly. When some acid is being added to the blood so that there are a lot of hydrogen ions available, then blood buffering systems start to work to maintain the pH level. Bicarbonate buffering system plays major role in regulating blood pH. In bicarbonate buffering system carbonic acid serves as hydrogen ion donor; when some base is added to blood plasma, carbonic acid dissolves into hydrogen cation and bicarbonate anion. When some acid is added to blood, bicarbonates take up hydrogen ions to become carbonic

Was the pH level always within the “normal” range for the human body? Yes it was.

One of the basic concepts that new nurses need to learn is that homeostasis in the body is maintained by the acid base balance in the body. That concept is critical when looking at arterial blood gases. This can help guide the nurse to anticipate what the doctor will order and the education that she needs to give the patient and the family. This case study should help to illustrate the point.

Acid-base balance in the body is important to maintain our normal functions. The regulation of hydrogen ions is essential for the body to perform normally and to achieve homeostasis. Our bodies maintain a pH level between a small margin of 7.35 to 7.45. If the pH level becomes too low, the body goes into a state called acidosis. On the contrary, if it elevates too far, the body enters into a state called alkalosis.

The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. (Tortora, G., Derrickson, B., 2014)

Acidosis is when the pH of one’s blood is below the normal level of 7.35. Alkalosis is when the pH of one’s blood is above 7.45. These can be broken down into two categories respiratory and metabolic. Normal oxygen (CO2) levels are 35-45 mmHg in systemic arterial blood. Normal levels for HCO3− 22-26mEq/liter in systemic arterial blood.

If an acid-base disturbance shifts the pH outside of the physiologic range, various control measures are activated to resist the change in pH. Compensatory mechanisms try to preserve the normal 20:1 ratio of bicarbonate to carbonic acid to keep the pH at normal range. The body works to maintain normal ratios through a compensation mechanism using renal and respiratory methods (Crowley, 2010).
