Subdivision of Lung Volumes and Capacities in Humans | Biology

In this article we will discuss about the subdivisions of lungs and capacities obtained by a spirometer with the help of suitable diagrams. 1. Lung Volumes: (i) Tidal Volume (TV = 500 ml): The TV (or Resting Tidal Volume, RTV) is the volume of air breathed in and out during quiet respiration (about 500 ml). (ii) Respiratory Minute Volume (RMV): [...]

Diffusion: Definition and Factors | Respiration | Humans | Biology

In this article we will discuss about:- 1. Meaning of Diffusion 2. Factors Controlling Diffusion 3. Diffusing Capacity for O2 and CO2. Meaning of Diffusion: Diffusion means movement of a substance from an area of high concentration to an area of low concentration. In the present context the diffusion of O2 from alveoli to pulmonary capillaries and of CO2 in [...]

Contents of CO2 in Blood of Human Beings | Respiration | Biology

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 [...]
