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): [...]

Respiratory Dead Space: Definition and Types | Humans | Biology

In this article we will discuss about:- 1. Definition of Respiratory Dead Space 2. Types of Respiratory Dead Space 3. Measurement. Definition of Respiratory Dead Space: The respiratory tract is so designed that during inspiration its upper part upto the level of terminal bronchiole is filled with atmospheric air. The first part of the expired air, therefore, is also atmospheric [...]

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 [...]
