Respiratory System: From Inspiration to Expiration Explained in Simple Words
The respiratory system is composed of the nose or nasal cavity, the pharynx, the larynx, the trachea, the bronchi, and the lungs. The respiratory system's functions are gaseous exchange, inhaling oxygen and exhaling out carbon dioxide,...

Dalton's Law and Partial Pressures
We know about the ideal gas laws, like Boyle's and Charles's and so forth. Now let's look at one law that involves mixtures of gases. This is called Dalton's Law, and to understand it, we have to learn about the concept of partial...
