CO2 combines with H2O in blood plasma to form H2CO3 (carbonic acid). Carbonic acid readily dissociates into HCO3 + H+ .
The reaction between CO2 and water happens inside red blood cells, and the reaction is catalyzed by the enzyme carbonic anhydrase.

What Contain hemoglobin and transports oxygen to the body tissues and removes CO2 from the body tissues?
The circulatory system ie blood.
Most of the carbon dioxide in the blood is transported asMost of the carbon dioxide in the bood is transported as?
Blood transports CO2 from tissue cells to the lungs in 3 forms:1) Dissolved in blood plasma (7 -- 10%)2) Chemically bound to Hb (around 20%), it forms a compound named carbaminohemoglobin. This reaction occurs rapidly and does not require an enzyme. CO2 binds directly to the amino acids of the Hb protein molecule.3) As bicarbonate ion (HCO3-) in plasma (about 70%): CO2 permeates (by simple diffusion) into the RBCs and combines with water. This reaction requires the presence of an enzyme called carbonic anhydrase. The result is carbonic acid (H2CO3), an unstable compound that quickly dissociates into H+ and HCO3-:CO2 + H2O + enzyme -------- H2CO3 -------- H+ + HCO3-The H+ formed, as well as CO2 itself, bind to hemoglobin molecules, triggering the called (Bohr effect). Thus, oxygen release is enhanced by CO2 loading. Because of the buffering effect of Hb, the liberated H+ causes little change in blood pH: arterial blood pH= 7.40; venous blood pH= 7.34.(Ahmed Urbizo, MDC STUDENT)
What happens to blood when it reaches the tissues?
when the blood reaches to the tissues then the cells embedded inside it absorbs the oxygen from the haemoglobin present inside the blood and blood absorbs all the waste material from the tissues like CO2,etc.then the blood passes the waste materials to the lungs AND AFTERWARDS it comes out through the process of respiration.
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 is the relationship between increased blood carbon dioxide respiratory rate and depth?
CO2 is the primary cvontrol for rate of breathing (not oxygen as many would expect). High levels of CO2 are very toxid to the tissues of the body and os it was allowed to remain in the blood most of these tissues would die off. And so sensors within the blood systmem detect the CO2 levels and stimulate faster deeper breathing if thesae elvels are to high for safety.
How wiil you describe the sequence of oxygen carbon dioxide and blood flow?
Blood flows in a circle from lungs to tissues and back. At the lungs O2 gets into the blood and CO2 gets out - at the tissues O2 leaves the blood and CO2 enters.
What kind of chemical is in your red blood cells that can pick up oxygen and carbon dioxide?
hemoglobin it contains Iron (Fe) which is why its important to get a source of iron in your diet Each hemoglobin can carry 4 oxygen molecules-if oxygen was not bound in hemoglobin the blood would not be able to have a high enough saturation to supply tissues Carbon dioxide does not use hemoglobin as much as oxygen and more carbon dioxide can be dissolved in the blood itself compared to oxygen Also using the bicarbonate buffer CO2 is converted into HCO3- which can be even more dissolved in the blood than CO2 alone
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
What Contain hemoglobin and transports oxygen to the body tissues and removes CO2 from the body tissues?
The circulatory system ie blood.
What do blood tissues carry?
Hormones,O2,CO2,Digestive products,excretory products
Why is the hematocrit value of venous blood slightly more than that of arterial blood?
It might be due to Hamburger's effect( chloride shift). In venous blood, RBC will take up CO2 and CO2 react with water to form carbonic acid ( H2CO3). This acid will then dissociate to form hydrogen ion ( H+) and bicarbonate ion (HCO3-). HCO3- will flow out from RBC and each efflux of HCO3- will be accompanied by influx of Cl-. In some circumstances, some HCO3- and Cl- remain in RBC or maybe the rat eof exchange of HCO3- and Cl- is not the same, and this create water flow into RBC, thus volume of RBC will increase (RBC swells) and hence it's hematocrit value too.
What gas is necessary for respiration?
The gases necessary (yes there are more than one) for respiration are oxygen and carbon dioxide. Oxygen plays the simpler role of the two. It is required by all cells of the body and can be passed along to the tissues via hemoglobin in red blood cells. Carbon Dioxide actually plays a very important role. It is the metabolic waste produced by cells, and it can be converted into bicarbonate ions by rbc to be transported in the blood, or bound to the globulin of hemoglobin and transported in this way. Its important role is its levels control respiration via peripheral and central chemoreceptors. To high CO2 levels and hyperventilation will reduce it or CO2 + H2O will be converted to bicarbonate ion (HCO3) and H ion. When CO2 is too low - hypoventilation will raise CO2 levels or the conversion of bicarbonate + H back to CO2 and water. It also plays and integral role in maintaining blood pH.
What is the chemical reaction to CO2 plus H2O-- HCO3?
elements and components
Does baking soda raise your PH in your body?
Baking soda does raise your blood pressure. Since Baking soda raises blood pressure and if your blood pressure is high then there will be a higher diffusion of Nutrients, O2, Proteins at the arterial end of the capillary into the Interstitial Fluid due to a higher pressure gradient and thus at the venous end of the capillary a low concentration of CO2 (produced by the cells) will diffuse from the interstitial fluid into the venous end of the capillary. So overall the dissolved CO2 in the blood will be low. So how does CO2 relate to pH? we know that CO2 combines with H2O to form Carbonic Acid; Carbonic Acid in turn disassociates to form H+ and HCO3- CO2 + H20 --> H2CO3 --> H+ + HCO3- Since the CO2 level in the blood is low there will be Less H+ in the blood and therefore the pH of the blood will be high, Causing Alkalosis.
The buffer system in blood is formed by?
The buffer system that operates in blood plasma is the bicarbonate buffering system. The chemical equation for this system is the following CO2 + H2O <--> H2CO3 <--> HCO3- + H+.
What is Ka for H2CO3 aq H aq HCO3 aq?
Ka= [h+][HCO3-]/[H2CO3]
What is the main function of blood?
The main function of blood is to supply oxygen,nutrients to the tissues,removal of waste such as CO2,urea and regulation of body temperature.
