How do the blood carbon dioxide levels and blood hydrogen ion and bicarbonate ion levels change while a child is holding her breath?
Carbon dioxide is transported in our blood to the lungs in one of three ways:
1. Dissolved in the plasma (10% of CO2 does this)
2. Attached to one of the amino groups on hemoglobin, to form a carbaminohemoglobin (HbCO2) (about 30% travel this way)
3. As bicarbonate in the plasma (about 60% go this way)
I think your question relates most to the last option, so I'll just cover that.
For CO2 to move to the lungs as bicarbonate, a few things have to happen at the tissues:
-The CO2 enters the red blood cell
-The red blood cell has carbonic anhydrase, an enzyme in it
-The carbonic anhydrase allows the CO2 to join with water, which forms Carbonic acid. That formula is:
CO2+H2O (in the presence of carbonic anhydrase) → H2CO3
-Carbonic acid is a weak acid. It breaks apart in the red blood cell to H+ and HCO3- (a hydrogen ion and bicarbonate)
-the HCO3- will trade places with an ion of Chloride, which is outside the Red Blood Cell, floating around in the plasma. The Cl- and HCO3- are both negatively charged, so no charge change takes place. This is called the chloride shift.
-So now the bicarbonate is in the plasma, and the H+ is in the RBC. The H+ will join with a molecule of Hemoglobin to form HHb or HHbO2 if an oxygen is attached.
-When the RBC reaches the lungs, the bicarbonate shifts again with the chloride ion, and it rejoins again with the H+ to form H2CO3 carbonic acid
-Under normal circumstances, in a breathing human, this carbonic acid will split into H2O and CO2, and the CO2 will be exhaled.
Your question however is about a child who is holding her breath.
The transport of ions moves in the same way, but once in the lungs, the CO2 will not be able to be exhaled. So her blood CO2 levels will increase, which will cause her blood to become more acidic. She will be able to hold her breath consciously for a short time only; if she passes out, the chemoreceptors located in the medulla oblongata and the pons will detect a decrease in pH, and will increase breathing rate to restore homeostasis.
What else can I help you with?
How does holding your breath increase the carbon dioxide level in the blood?
When you hold your breath, your body continues to produce carbon dioxide as a byproduct of metabolism. However, because you are not exhaling this carbon dioxide, it accumulates in the bloodstream, leading to an increase in its level. This triggers the urge to breathe in order to expel the excess carbon dioxide from the body.
What would most likely happen if a person's body stopped producing carbonic anhydrase?
If a person's body stopped producing carbonic anhydrase, they would not be able to efficiently convert carbon dioxide and water into bicarbonate and hydrogen ions. This could lead to a buildup of carbon dioxide in the blood, causing respiratory acidosis and potentially leading to symptoms such as dizziness, confusion, and shortness of breath.
What is added to the body removed from the body with every breath?
Carbon dioxide
Held your breath what would the concentration of air in your lungs do?
If you hold your breath, the concentration of oxygen in your lungs will decrease as your body uses up the available oxygen. At the same time, the concentration of carbon dioxide will increase as it accumulates from your body's metabolic processes. This imbalance triggers the urge to breathe and is essential for maintaining proper gas exchange in the body.
Why can't I hold my breath as long as I want?
Because you need oxygen to survive, and if you don't get the air, that carries oxygen, you will die. But you can practice holding it for longer periods of time, but if you hold it for to long, you may feel faint, so I suggest not to do that.
What is it called when you feel pleasure by holding your breath in?
The sensation of pleasure from holding your breath is often referred to as "breath control" or "breath play." Some individuals may experience a rush of euphoria due to the buildup of carbon dioxide in the blood, which can create a feeling of lightheadedness or exhilaration. However, it's important to approach breath-holding with caution, as prolonged oxygen deprivation can be dangerous.
What happens to the partial pressure of carbon dioxide during breath holding?
The partial pressure of carbon dioxide increases as a function of time, depending on how long you hold your breathe. Initially, this will cause some discomfort and lead to a mild headache or muscle fatigue if you are not breathing properly during strenuous exercise. However, with proper training (like that undertaken by swimmers), you can hold your breath longer while pushing your body to perform optimally.
Why do you need oxygen hydrogen and carbon dioxide to support life?
because we need oxygen to be able to breath and without carbon dioxide, oxygen couldn't exist.
Does holding your breath cause weight loss?
No, there is no weightloss benefit to holding your breath.
What is reath holding?
Breath holding is a technique they teach in swimming so you can go the maximum distance on the longest breath. Breath holding can be tricky to learn.
Holding your breath under water?
Holding your breath underwater is when your head/face is underwater and you do not breath.
What sends a message to your brain when you hold your breath?
Holding your breath increases levels of carbon dioxide in your body, which signals the brain to trigger the urge to breathe. Receptors in the body called chemoreceptors sense the changes in carbon dioxide levels and send signals to the brainstem, prompting it to initiate breathing.
What is breath holding test?
The breath holding test determines how long you can hold your breath. These tests can be played for fun or run for medical purposes.
What is breaking point in breath holding?
the point at which a person cannot hold breath further for a second is termed as the breaking point in breath holding.
What factors affect your ability to hold your breath?
AnswerThe factors of how long you can hold your breath are:~a) How big your lungs areb) How fit and healthy you arec) How much you have practised holding your breath.d) Hom much CO2 your body is storing.Good question!
What do penguins with there large lungs for holding its breath?
penguins breathe with large lungs for holding breath to swim.
Are high levels of carbon dioxide bad?
well, you don't breath carbon dioxide, you breath oxygen
