The ability of a monkey to be able to exchange gases with its environment and deliver oxygen throughout its body is through the activities of the respiratory system.
<h3>What is respiratory system?</h3>
The respiratory system is defined as one of the body systems that are made up of a network of tissues and organs that aid in the exchange of carbon dioxide and oxygen.
The oxygen passes from the environment into the nostrils. It is then conveyed by the trachea to the bronchi and arrives at the alveoli where the oxygen is delivered to the body cells.
Therefore, the ability of a monkey to be able to exchange gases with its environment and deliver oxygen throughout its body is through the activities of the respiratory system.
