What is the external respiration process?
External respiration, also known as breathing, involves both bringing air into the lungs (inhalation) and releasing air to the atmosphere (exhalation). During internal respiration, oxygen and carbon dioxide are exchanged between the cells and blood vessels.
What is the product of external respiration?
Internal and External Respiration Internal respiration occurs in the body tissues, where cells release carbon dioxide and take in oxygen from the blood. External respiration occurs in the lungs or gills and occurs when the body takes in oxygen from the atmosphere and releases carbon dioxide.
What is external respiration answer?
External Respiration is actually the breathing process that is the gaseous exchange between the external environment and the blood stream. In humans and other mammals, oxygen is taken into the body by lungs while in some other animals it occurs by diffusion across the surface of the body.
What is external respiration quizlet?
external respiration. the exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries.
What is external respiration with example?
External respiration, commonly known as breathing, is the exchange of oxygen and carbon dioxide between an animal and its environment. Most animals use specialized organs or organ systems, such as lungs, trachea, or gills, for external respiration.
What is external respiration Byjus?
External respiration refers to breathing and exchange of gases between the external environment and lungs and between alveoli surface and the blood stream.
What are the 4 processes of external respiration?
The components of external respiration include alveolar surface area, ventilation and perfusion matching, and partial pressure gradients. Partial pressure gradients allow gasses to flow from areas of high pressure to areas of lower pressure.
Which of the following occurs with external respiration?
External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. Internal respiration is the exchange of gases with the internal environment, and occurs in the tissues….

What is external respiration Class 7?
Answer: Taking in oxygen and giving out carbon dioxide is called breathing or external respiration.
What is external respiration Class 11?
What happens in external respiration external respiration?
External Respiration Exchanges Gases Between the Lungs and the Bloodstream. Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through hundreds of millions of microscopic sacs called alveoli.
What is external respiration Class 9?
External respiration also known as breathing refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. Exchange of gases both in and out of the blood occurs simultaneously.
