1. What is the primary function of the nose?

To regulate body temperature

To control the sense of taste

Air enters ( there are hairs to catch and trap dust to prevent dust from entering the lungs)

To produce tears for crying

The primary function of the nose is to filter and warm air before it enters the lungs by catching and trapping dust particles.

Explanation

The primary function of the nose is to filter and warm air before it enters the lungs by catching and trapping dust particles.

2. What is the function of the nasal cavity?

The nasal cavity is where the sense of touch originates in the head.

The nasal cavity serves as the primary organ for hearing in humans.

Large space above the mouth, warms and cool, forms mucas to moisten air

The nasal cavity is primarily responsible for taste perception.

The nasal cavity functions to warm and cool air, as well as produce mucus to moisten the air we breathe in.

Explanation

The nasal cavity functions to warm and cool air, as well as produce mucus to moisten the air we breathe in.

3. What is the scientific term for the wind pipe?

Pharynx

Bronchi

Esophagus

Wind pipe, coming from larynx going to the branchi

The trachea, commonly known as the wind pipe, is the tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Explanation

The trachea, commonly known as the wind pipe, is the tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

4. What is the function of the oral cavity?

Passage way for air to flow in and out of body

It is responsible for regulating body temperature.

It is where food is digested.

It is involved in filtering waste from the body.

The oral cavity is primarily responsible for allowing air to flow in and out of the body, aiding in the process of respiration.

Explanation

The oral cavity is primarily responsible for allowing air to flow in and out of the body, aiding in the process of respiration.

5. What is unique about the left lung compared to the right lung?

The left lung is larger in size than the right lung

The left lung is responsible for oxygenating the blood

The left lung is located on the right side of the chest

The left side of your body, has 2 lobs (because there is not enough room for 3 like the right the heart is in the way)

The left lung consists of 2 lobes due to the space constraints created by the heart being positioned closer to that side of the body, unlike the right lung which has 3 lobes.

Explanation

The left lung consists of 2 lobes due to the space constraints created by the heart being positioned closer to that side of the body, unlike the right lung which has 3 lobes.

6. How many lobes does the right lung have?

Has 3 lobes

The right lung has 3 lobes, while the left lung only has 2 lobes. This is due to the presence of the heart on the left side of the chest.

Explanation

The right lung has 3 lobes, while the left lung only has 2 lobes. This is due to the presence of the heart on the left side of the chest.

7. What are bronchi?

Blood vessels that carry oxygen-rich blood away from the heart

2 short tubs that carry air from the trachea to left and right lungs. (covered by cilia- tiny hairs inside air tubs to keep dust out of lungs)

Small air sacs in the lungs where gas exchange occurs

The windpipe that carries air to the lungs

Bronchi are specifically defined as the 2 short tubes that carry air from the trachea to the left and right lungs, and are lined with cilia to trap dust particles and prevent them from entering the lungs.

Explanation

8. What are bronchioles?

Large airways in the respiratory system.

Thin membrane surrounding the lungs.

Smaller tubes branching off bronchi lead to alveoli

A type of blood vessel in the lungs.

Bronchioles are small air passages that branch off bronchi and lead to alveoli, where gas exchange occurs in the lungs.

Explanation

Bronchioles are small air passages that branch off bronchi and lead to alveoli, where gas exchange occurs in the lungs.

9. What are alveoli?

Tiny air sacs of the lungs. for gas exchange surrounded by capillaries

Blood vessels in the brain

Muscles in the abdomen

Bones in the feet

Alveoli are specifically located in the lungs and are responsible for gas exchange with the capillaries surrounding them.

Explanation

Alveoli are specifically located in the lungs and are responsible for gas exchange with the capillaries surrounding them.

10. What is the function of the diaphragm?

A tool used for gardening

A bone in the leg

A type of fruit

Sheet muscle that separates the inside or your chest from the intestines

The diaphragm is a sheet muscle that plays a crucial role in breathing by separating the chest cavity from the abdominal cavity.

Explanation

The diaphragm is a sheet muscle that plays a crucial role in breathing by separating the chest cavity from the abdominal cavity.
