• The system comprises of the airway, the lungs which are the functional unit of the respiratory system and the muscles of respiration which includes the diaphragm and the intercostal muscles.  

2. Answer;

The statement “the lungs are made up of thick fibrous tissue” is false

Explanation;

• The lungs are part of the respiratory system which act as the functional units of the respiratory system by passing oxygen into the body and carbon dioxide out of the body.
• Lungs are a pair of spongy, air-filled organs that are located on either side of the chest. The lungs are designed with features that makes it adapted to its functions; for example its inner surface of the lungs is made up of air sacs of the alveoli which increases the surface area for the gaseous exchange.  

3. Answer;

The statement “internal respiration takes place in the alveoli” is false

Explanation;

• Respiration may be divided into external respiration and internal respiration.  
• External respiration takes place in the lungs where the oxygen gas diffuses into the blood and carbon dioxide diffuses the alveolar air.
• Internal respiration on the other hand takes place in the metabolizing tissues of the body; where oxygen gas diffuses out of the blood and carbon dioxide diffuses out of the cells.

4. Answer;

The statement “the alveoli are located at the end of the bronchi” is false

Explanation;

• Alveoli are tiny sacs that are found within the lungs which allow the movement of oxygen and carbon dioxide between the lungs and the blood stream.
• Alveoli sit at the end of the respiratory tree and are arranged in clusters throughout the lungs. They are found at the end of the bronchioles.

5. Answer;

The statement that “the hemoglobin in blood combines with oxygen when the blood flows through areas where oxygen concentration is high” is true.

Explanation;

• The red blood cells collect the oxygen from the lungs where oxygen is highly concentrated and carry it to the parts of the body where it is needed.
• During this process, the red blood cells collect the carbon dioxide and transport it back to the lungs, where it leaves the body when we exhale.

6. Answer;

The statement “Marijuana does not contain carcinogens” is false.

Explanation;

• Marijuana smoke contains harmful chemicals such as bronchial irritants, tumor promoters and carcinogens.

Explanation;

• The amount of time that Marijuana remains in the system depends on factors such as the concentration of THC in marijuana, the frequency of use, the quantity used, and also individual metabolism. For example, for a daily use, the drug can remain in the system for up to a month or longer.  

9. Answer;

The statement “the drug THC acts as a stimulant and can improve strength, balance, and coordination” is false.

Explanation;

• Marijuana is the dried flowers, leaves, stems and seeds of the cannabis sativa plant. The plant contains THC which is the active component and other similar compounds which causes the effects the mind-altering effects of a drug.
