Explanation:
Inflammation is the body defence system against various pathogens and include various components such as Immune cells and blood vessels. Inflammation occurs in a sequence of events.
- when a pathogen enters the cells macrophages produce the first response by phagocytizing the foreign body.
- The blood vessels dilated so more blood cells, oxygen and nutrients could reach at the site of pathogen and fight against it.
- Foreign pathogen is captured at that place so it can't mobilize to other part of the body.
- The more fighting cells are directioned at the site of infection
- The recruited phagocytic cells phagocytize the invaders pathogen and starts its degradation.
Olfaction is not a tactile sensation, nor it's related to chewing food.
Olfactory receptors are chemical receptors in the nasal cavity that react with different odors creating the sense of smell that is interpreted in the brain.
So, olfaction is a chemical sensation that we experience while inhaling different odors through our noses.
