2.
What would happen if the nostrils had no tiny hair?
Correct Answer
B. You could get sick easily
Explanation
If the nostrils had no tiny hair, they would not be able to filter out dust, allergens, and other particles in the air that we breathe. This would make it easier for harmful substances to enter our respiratory system, increasing the risk of getting sick. The tiny hairs in the nostrils play an important role in trapping and preventing these particles from entering our lungs, so without them, our immune system would be more vulnerable to infections and illnesses.
3.
Which is NOT a function of the nasal cavity?
Correct Answer
C. Send messages to the brain
Explanation
The nasal cavity is responsible for allowing air in and out of the body and contains a mucous membrane that helps to filter and humidify the air. However, it is not involved in sending messages to the brain. The olfactory receptors in the nasal cavity play a role in detecting smells, but the actual transmission of these messages to the brain occurs through the olfactory nerve.
4.
The mucous membrane gives off a sticky fluid called _____.
Correct Answer
B. Mucus
Explanation
The correct answer is "Mucus". The mucous membrane, also known as the mucus membrane, produces a sticky fluid called mucus. Mucus is a thick, slimy substance that helps to lubricate and protect various organs and tissues in the body. It plays a crucial role in trapping and removing foreign particles, such as dust and bacteria, from the respiratory and digestive systems.
5.
Where are the nerves located that detect chemicals that cause smell?
Correct Answer
B. At the roof of the nasal cavity
Explanation
The nerves that detect chemicals that cause smell are located at the roof of the nasal cavity. This is where the olfactory epithelium is located, which contains specialized cells called olfactory receptor cells. These cells have tiny hair-like structures called cilia that extend into the nasal cavity and are responsible for detecting and transmitting signals about different smells to the brain.

14.
Taste and _______ go together.
Correct Answer
B. Smell
Explanation
Taste and smell are closely related senses that work together to enhance our perception of flavor. When we eat, the molecules from the food stimulate our taste buds, which can only detect basic tastes like sweet, sour, salty, bitter, and umami. However, it is our sense of smell that allows us to differentiate between different flavors and fully experience the taste of food. The aroma of food travels from the back of the throat to the olfactory receptors in the nose, providing us with additional information about the food's taste. Therefore, taste and smell are interconnected and complement each other in our sensory experience of food.
15.
What should you do FIRST if your nose bleeds?
Correct Answer
B. Bend slightly forward

When your nose bleeds, the first thing you should do is bend slightly forward. This is because bending forward helps to prevent blood from flowing down the back of your throat, which can cause you to swallow blood and potentially irritate your stomach. By bending forward, you allow the blood to flow out of your nose instead.
