External respiration consist in three steps:
- Pulmonary ventilation (inhalation and exhalation.)
- Gas diffusion.
- Transport of Oxygen (O2) and Carbon dioxide (CO2).

What are the two parts of external respiration?
inhaling and exhaling
Define external respiration?
External Respiration-the process of first inhaling oxygen (02) and then proceeding to EXHALING the inhaled oxygen in the lungs in the form of carbon dioxide (C02) into the environment, then repeating the process all over again. (the entire process is commonly known as cellular respiration.)
Why is the tip of the nose an ideal location for the external nares?
The location is best for respiration. The air is not restricted to a curved or misshapen pathway that causes delays in air being drawn into the lungs.
Does a leech have a respiratory system?
Yes... They breathe through the skin. One family of leeches is known to have external gills. However, gas exchange usually occurs at the body surface where oxygen is absorbed.
A type of respiration pertaining to cells?
Respiration is when oxygen combines with sugar to break down the sugar.
Why is external respiration vital to cellular respiration?
Cellular respiration need oxygen. This oxygen is supplied by external respiration
How does external respiration work?
well what happens is the repiration is external
Name the organs of external respiration?
Lungs and Gills are both used for external respiration
Differentiate between external inertial cellular respiration?
The external inertial respiration refers to breathing, while the cellular respiration refers to respiration between the cells.
What are the 2 steps in respiraton?
The 2 steps of respiration are;breathing and cellular respiration.
External respiration involves?
External respiration is the exchange of gases between each lung and blood. It involves inhaling gases from the organisms external environment, and then exhaling the gases back out.
What is external respiration and internal respiration?
External respiration is to breathe and facilitate gas exchange in the lungs or an analogous body cavity, depending on the organisms anatomy. Cellular respiration is the process of oxidative phosphorylation, where ATP energy is generated from biomolecules by the cell. In aerobes, the process involves a series of electron steps and oxygen is the terminal electron acceptor
What is the difference from respiration and breathing?
Internal Respiration: Is changing food (glucose) into energy. External Respiration: Is breathing in and out.
What is the difference between external respiration and tissue respiration?
External respiration is gas exchange in the lungs. Tissue respiration is the chemical reactions in our cells which produce energy. The most usual one is aerobic respiration: glucose + oxygen --> carbon dioxide and water.
What does internal and external respiration mean?
External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.
How are steps of cellular respiration different when it is anaerobic respiration?
Anaerobic means without air, so there is no respiration.
How are the step of cellular different when it is anaerobic respiration?
The steps of cellular respiration is different when it is anaerobic respiration compared to aerobic respiration. The main difference is because aerobic respiration uses oxygen and anaerobic uses other elements but the other steps are similar.
