1. Taste and Smell

2. Objective
SWBAT explain how taste and smell are related to each other by participating in a class discussion.

3. Sense of Smell Humans: 12 million olfactory receptors
Bloodhounds: 4 billion
Of the 1,000 or so genes that encode the human olfactory receptor proteins, about 600 have mutated into inactivity. In monkeys, apes, dogs, and mice, a much higher proportion of their olfactory genes remain active WHY?
These animals rely more on a sense of smell to identify food than humans do
Evolution has diminished the human sense of smell compared to other animals
Talk on Thursday. Just talk about how taste and smell are different for humans and animals. Have a class discussion

4. Why do you think taste and smell are related to one another?

5. Taste and Smell Human can taste: Sweet, Sour, Salty, Bitter, and Umami
Odors come from the air while taste comes from chemicals in the food
If we do not have a receptor for the odor  no smell  no flavor  no taste

From the video, what are your thoughts about it? Why do you think it happened? How would you feel if this happened to you?
From my research, it’s rare to have it happen and it’s even rarer that you lose your entire sense of taste but it can happen but it’s extremely rare. It can be that something hahppened to your taste receptors while you were sick, the nerves died, or there’s a deeper underlying problem.
