Answer:
With a foundation of anatomy and physiology, you will have the building blocks to make the proper decisions and provide accurate and quality care. Of course, the study of anatomy and physiology is not static. New innovations in science and medicine change our understanding of the human body all the time.
In a nutshell:
- Chemical reactions love stability.
- Usually if heat is given off, the chemicals are happier as they are more stable.
- This should happen naturally, like a ball rolling down a hill.
- But if you <em>force </em>chemicals to do things that make them more <em>unstable, </em>you're going to have to put energy in.
- Like forcing a ball up a hill, it isn't naturally going to roll up without you putting in energy.
- "exo-" means "away from" and "endo-" means "within". Think about this in terms of heat, or energy.
- heat released -> exothermic reaction (energy escapes)
- heat put in -> endothermic reaction (energy is put within)
Also the word "enthalpy" and ΔH is used a lot to relate to energy.
A negative ΔH means heat loss and a positive ΔH means heat put in as well.
Hope this helps ;)
<h3>Answer:</h3>
Vacuole is a storage sac like organelle for solid or liquid content.
Its function is to provide rigidity and turgidity. It also stores proteins, food, etc.
This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.
