<h3>
What is Respiration?</h3>
- The respiratory system, also known as the respiration or ventilatory system, is a biological system in both plants and animals that consists of a variety of organs and structures that are employed for gas exchange.
- Depending on the organism's size, environment, and evolutionary background, the anatomy and physiology that cause respiration vary widely.
- In land animals, the respiratory surface is internalized as the lining of the lungs.
- Gas exchange in the lungs takes place in millions of tiny air sacs, known as alveoli in mammals and reptiles and atria in birds.
- The air is in close touch with the blood in these tiny air sacs because they have an abundant blood supply.

Gene regulation is necessary in the development of multi-cellular organisms because it is necessary to make sure certain things go where they are needed to go. Multi-cellular organisms have more organ systems, therefore depend on more cells to live. Cells have a memory; the genes a cell expresses and the way it behaves depend on the cell's past, as well as its present environment.
ABNORMAL - Respiratory depression is never normal after a procedure. They will use a local anesthetic to decrease the gag reflex, but this should not affect the respiratory drive. Respiratory depression should be addressed immediately.
