Why what we know about cells is called a theory and not a law
Afina-wow [57]
The term "law" is a historical relic going back to Newtonian times, when after Newton's development of classical mechanics, it was thought that the workings of the universe were directly analagous to a perfectly constructed and perfectly predictable clockwork. That was turned on its head as a result of quantum mechanics, and modern scientists typically avoid use of the term "law" anymore because it is too dogmatic. Newton's "Laws" are still called that mainly for historical reasons now. What used to be called laws are now called theories.

What is the order of the breathing process
NemiM [27]
Step 1-
Your diaphragm moves down as it contracts. Your ribs move outward. These movements make the space inside the chest larger.
Step 2-

Air rushes in through the nose and mouth and passes through the throat. Air then moves past the epiglottis which is open into the trachea.

Step 3

Air moves into your bronchi. The bronchi branch out and end in tiny air sacs, called alveoli.

Step 4

<span>Air moves into your alveoli. Oxygen moves through the walls of alveoli and capillaries, entering the blood.</span>

Step 5

Carbon dioxide moves from the blood through the walls of capillaries and alveoli in order to be expelled by the lungs.

Step 6

Your diaphragm moves up as it relaxes. Your ribs move inward. These movements make the space inside the chest smaller.

Step 7

<span>Your lungs are squeezed and air is pushed out of the alveoli. The air travels back through your bronchi, trachea, and nose and mouth.</span>
