What are the types of epithelial tissue and where can they be found?
1. Simple squamos: helps with diffusion & filtration and is found in the blood vessels and air sacs in lungs.
2. Simple cuboidal: helps with secretion & absorption of molecules and is found in the kidney tubules and covering the ovaries.
3. Simple columnar: helps with secretion & absorption of nutrients and is found in the digestive tract and uterus.
4. Stratified squamos: helps with protection and is found in lining body cavities (skin, nose, esophagus, mouth)
5. Pseudostratified columnar: helps with secretion and cillia aided movement and is found in air passages and tubes in the reproductive system.
6. Stratified columnar: helps with secretion and absorption and is found in the lungs and uterus.
7. Stratified cuboidal: helps with protection and secretion and can be found in the pancreas, salivary glands, and sweat glands.

What is the difference between an isotonic, hypertonic, and hypotonic solution?
Isotonic solutions have the same, or equal, solute concentrations, so there is no net movement of water.
Hypertonic solutions have a high concentration of solute, meaning that water moves out of the cell and will shrink.
Hypotonic solutions have a low concentration of solute, meaning that water moves into the cell and it swells.
