To determine: The change in the amount of oxygen dissolved in the plasma when the
Introduction: Blood is one of the important connective tissues in the body that helps in the transportation of gaseous molecules (oxygen and carbon dioxide mainly) and other nutrients from one part of the body to another.
b.
To explain: The change in the amount of oxygen that is bound to hemoglobin when
Introduction: Gases travel through the blood in dissolved as well as in bounded form. This binding of gases depends on the partial pressure of the gas itself. A change in the partial pressure of the gas in blood also changes its concentration in the blood.

- Explain how oxygen and carbon dioxide are transported in the blood. How does the means of transport relate to the solubility and chemical reactivity of these gases in plasma?arrow_forwardWhy does hemoglobin have high affinity for oxygen in arterial blood and lower affinity in capillaries beds? Explain in terms of blood oxygen pressure.arrow_forwardin thalassemia, a type of anemia, the hemoglobin molecule is malformed. The malformation prevents hemoglobin from carrying and delivering the correct amount of oxygen to the cells. Which important physiological concept does this example illustrate?arrow_forward
- Will a decrease in elevation shift the binding curve of hemoglobin? Will it shift the curve to the left or right, shift to myoglobin or no longer bind to O2?arrow_forwardMake a list of the different physiological equations: Equation to calculate CaO2 (content of oxygen in arterial blood) and assume 100% saturation and no oxygen diffused in solution; all is carried by hemoglobin (what is the hemoglobin binding constant?) =arrow_forward
