cavities. Body membranes are made up of epithelial and connective tissue layer. Mucous membrane cover openings that are exposed to the outside world. For example‚ mucous membrane is present in the nose‚ respiratory tract‚ male and female reproductive systems‚ stomach and intestines. Epithelium of mucous membrane is attached to lamina propria‚ a loose connective tissue layer that stabilizes the epithelium in place. Goblet cells in the epithelium make mucus which is a liquid that protects the mucous membrane

Central Nervous System Stimulants Types Stimulants can range from mild legal forms like caffeine to severe illegal drugs like methamphetamines. Each type has different effects at different levels and all can be lethal if taken in excessive quantities. The first type is the cocaine family which consists of cocaine HCL‚ cocaine freebase or crack‚ and cocaine paste. Then there are a wide arrange of amphetamines which are synthetic versions of the ephedra plant like Adderall which is used to help with

Respiratory System Respiration: The primary function of the respiratory system is to obtain oxygen gas for cell metabolism and remove carbon dioxide waste. Describe each of the following general processes of respiration. Ventilation- air is moved into and out of the lungs so the gases there are continuously changed and refreshed external respiration- oxygen diffuses from the lungs to the blood‚ and carbon dioxide diffuses from the blood to the lungs gas transport- oxygen is transported
