How would carbon dioxide loading/oxygen unloading at systemic tissues be affected if a person was exposed to a chemical that blocked the action of the enzyme carbonic anhydrase? Explain why.

Oxygen is mainly carried through blood in what form?

explain is oxygen and carbon dioxide are acidic or basic. explain how breathing can alter acidic/basic concentrations in blood

When travelling high altitude, one of the problem is alkalosis of the blood.  Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic.   To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney.   Q: How would blocking transport of HCO3- help to lower the pH of the blood?

Describe what happens with PCO2 levels and pH during normal breathing.

Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.

Explain why the gas values from the alveolar air to the blood change during pulmonary gas exchange. For example: Alveolar air for CO2 has a value of 40mmHg then when entering the blood shifts to 45mmHg. Why does this occur? I tried to calculate this by using Dalton’s law but I’m not Understanding.

how does an increased PaCO2, respiratory acidosis, alter the delivery of oxygen to the tissues?

What effect does hyperventilation have on blood pH and why? What simple measure can be used to correct the pH imbalance and how does it work? What effect would hyperventilation have on hemoglobin O2 saturation in a normal healthy individual? What effect would a PaO2 of 60 mmHg have on hemoglobin O2 saturation and why? (explain in terms of the O2-Hb dissociation curve)

why do oxygen levels decrease
