In this article we will discuss about the contents of CO2 in blood of human beings with the help of suitable diagrams. CO2 Content and Tension of Blood: Arterial blood contains about 48 volume of CO2 and venous blood 52 volume of CO2 per 100 ml, tension of CO2 being 40 mm Hg and 46 mm Hg in the arterial [...]
The normal rate or respiration in an adult is 14 to 18 per minute with a tidal volume of about 500 ml. The rate and depth of respiration (pulmonary ventilation per minute) is adjusted according to requirement of the body. For instance during muscular exercise metabolic activities are increased and the demand for oxygen by the working muscles is increased. [...]
In this article we will discuss about the contents of oxygen in blood of human beings. The O2 content of the arterial and venous blood and relevant data are given in the following table: It will be seen that about 98% of oxygen is present in the blood in chemical combination with haemoglobin and only 0.3 ml in arterial blood [...]
