"because your heart is pumping blood with less oxygen flowing throug your blood"
I want a better answer than the one I am about to give, but the CO2 that you are holding in raises the acidity of your blood (thus lowering the pH).
normal people take breaths because of a decrease in their pH. if you hold your breath your co2 levels increase and that triggers your pH to go down, which makes you take a breath.
1. We can physically try to hold on to our breath for a period of time, but the medulla oblongata will detect a drop of pH level (acidosis condition) and force a breath.
If the blood pH decreases below normal (below 7.35), it is known as acidosis. This can lead to symptoms such as confusion, fatigue, and shortness of breath. Severe acidosis can be life-threatening if not corrected promptly.
Yes, the kidneys play a major role in regulating the pH of the blood by selectively reabsorbing or excreting bicarbonate ions and hydrogen ions. This helps maintain the blood pH within a narrow range to support normal physiological functions.
Slow breathing can lead to a buildup of carbon dioxide in the blood, which can lower the pH of the blood (acidosis) by increasing the concentration of carbonic acid. This can disrupt the body's acid-base balance and lead to symptoms like dizziness, confusion, and shortness of breath.
The pH level of your blood is extremely important. The ideal pH level for blood is around 7.35, and your body goes to enormous lengths to maintain this level. If your blood pH were to vary 1 or 2 points in either direction, it would change the electrical chemistry in your body; there would then be no electrical "power," and in a very short time, you would die. This means that if your pH level is either too high [alkaline] or too low [acid], you will become ill, perhaps even die. A healthy pH level is very important to your health.
Blood pH = 7.40 (+/- 0.05) (THIS IS THE ANSWER TO THE PH OF BLOOD IS NEAREST TO WHAT NUMBER)=#7
Buffers help to stabilize blood pH levels by acting as a reservoir for hydrogen ions. When there is an increase in hydrogen ions, buffers can absorb them to prevent a drastic change in pH. Conversely, when there is a decrease in hydrogen ions, buffers can release them to maintain a stable pH level in the blood.
If the pH in the blood is too low (acidic), a condition called acidosis occurs. This can disrupt normal body functions and lead to symptoms such as confusion, fatigue, and shortness of breath. Severe acidosis can be life-threatening if not corrected promptly.
When you are hyperventilating or breathing at a very accelerated rate, your body is expelling carbon dioxide faster than your body can produce it. This causes the blood's pH to RISE, thus making it more alkaline, which initiates a restriction of the blood vessels. This prevents the transportation of oxygen to the brain and other areas of the nervous system so the patient tries to get more oxygen; exacerbating the problem. A solution to hyperventilation could be to breathe into a paper bag so that you are breathing in carbon dioxide and keeping the blood's pH at a normal level.
Breathing rapidly (hyperventilation) or slowly (hyperventilation) are ways the body may become unbalanced or attempt to compensate an imbalanced blood pH. The blood's normal pH is 7.35-7.45. Carbon dioxide (CO2) is acts to acidify the blood (lower the pH). Therefore, hyperventilating (deceasing the CO2 contained in the blood) increases blood pH. Inversely, hypoventilation creates a decline in blood pH.
pH of blood is typically tested using a blood gas analyzer that measures the acidity or alkalinity of the blood. A sample of arterial blood is usually taken from an artery in the wrist or groin for this test. Normal blood pH levels range from 7.35 to 7.45.
