Difference Between Ventilation and Respiration

Ventilation vs Respiration

的呼吸道和cardiovascular systems work together to ensure a constant supply of essential oxygen to every cell in the body and also the removal of carbon dioxide and other waste products from every cell. Both ventilation and respiration processes come under the respiratory system associated with the lungs and are essential for a continual life.

Ventilation

通风是空气向肺部进出的运动。这是发生氧合和呼吸过程的重要过程。通风缺乏4至6分钟会导致大脑损伤，并可能导致死亡。通风有两个主要阶段。灵感和到期（也称为吸气和呼气）。灵感是将空气转移到肺部的过程，而到期是将空气从肺部移出的过程。这两个过程接一个地进行，因此使一个通风周期由一个灵感事件和一个到期事件组成。在一个通风周期中交换的空气量被称为“通风量”或“潮汐量”，而在单位时间内发生的通风循环的数量称为“通风率”。这两个变量取决于活动水平和个体的生理氧需求。此外，通风受三种基本机制的影响。 namely, neural, chemical and mechanical.

呼吸

呼吸is the process of exchanging gases, mainly, oxygen and carbon dioxide. The gas concentration gradient helps to exchange the gases across the respiratory surfaces through the process of diffusion. In the body, the diffusion of the gases occurs very rapidly due to the short distance between diffusion tissues. In mammals, there are two types of respirations existent; namely, internal respiration and external respiration.

Internal respiration is the exchange of oxygen and carbon dioxide between the systemic circulatory system and the cells of the body. This process provides oxygen into the cells from the blood and removes carbon dioxide from the cells.

External respiration is the exchange of oxygen and carbon dioxide between the blood and fresh air and this occurs in between the alveoli of the lungs and the capillaries of the pulmonary circulatory system. External respiration is important, mainly to oxygenate the blood and to remove carbon dioxide from the blood.

What is the difference between Ventilation and Respiration?

• Ventilation facilitates the process of respiration. Without ventilation, respiration cannot occur.

• The ventilation is the movement of air into and out of the lungs whereas the respiration is the exchange of oxygen and carbon dioxide.

• The ventilation mainly involves the lungs while the respiration mainly involves the respiratory surfaces, including alveoli and blood capillary walls.

• Unlike in the respiration, two phases are involved in the ventilation; inspiration and expiration.

• In the process of the ventilation, the inhaled air has many gases, but in the respiration, it exchanges mainly oxygen and carbon dioxide.
