Simply put, the respiratory system does the following modifications to the air before it reaches the lungs. First, it warms the air. Second, it cleans the air from dust and dirt. Third and lastly, it moistens or humidifies the air.
1.) how does respiration differ from breathing?
The difference between breathing and respiration is that breathing is the process of taking in oxygen and expelling carbon dioxide while respiration is the process where the body breaks down the oxygen so that the cells in the body can use it to create energy.
5.) what gases are exchanged in the respiratory system?
The respiratory system is how we process oxygen in our body. This refreshes the blood in our veins and arteries. The gases that are exchanged in the respiratory system are oxygen and carbon dioxide.
7.) how is the sound of your voice produced?
The sound of your voice is produced through vibrations and the movement of air. This begins when a person inhales and air moves into the lungs. The air in the lungs is the source of power for your voice.
2.) what are the two functions of the respiratory system?
The two main functions of the respiratory system to supply blood containing oxygen in order for the blood to deliver oxygen to all parts of the body. It also enables gaseous exchange in the body such as oxygen and carbon dioxide during breathing.
6.) how do you inhale and exhale?
We inhale and exhale through the process of respiration. We inhale to move air into the lungs and exhale to move air out of the lungs. Respiration supplies the cells of the body with oxygen and remove the carbon dioxide produced by cellular activities.
3.) through what structures does air pass to get to the lungs?
Air passes through our respiratory system. It enters through the nasopharynx or the oral pharynx. It then enters through the epiglottis, larynx and the trachea. Before it reaches the lungs, it passes the bronchus and bronchioles.
