The Respiratory system is made up of trachea, the lungs, and the ______________.
- A.
Liver.
- B.
Diaphragm.
- C.
Esophagus.
- D.
Pancreas.
Correct Answer
B. Diaphragm.Explanation
The respiratory system consists of the trachea, the lungs, and the diaphragm. The diaphragm is a dome-shaped muscle located at the base of the chest cavity. It plays a crucial role in the process of breathing by contracting and relaxing. When the diaphragm contracts, it moves downward, allowing the lungs to expand and fill with air. When it relaxes, the diaphragm moves upward, causing the lungs to contract and expel air. Therefore, the diaphragm is an essential component of the respiratory system.Rate this question:

When you breath in air, you bring oxygen into your lungs and blow out_________________.
- A.
Carbon dioxide.
- B.
Carbon monoxide.
- C.
Oxygen.
- D.
Hydrogen.
Correct Answer
A. Carbon dioxide.Explanation
When you breathe in air, you bring oxygen into your lungs, which is then transported to your cells through your bloodstream. During this process, your cells produce carbon dioxide as a waste product. When you exhale, you release this carbon dioxide from your lungs back into the air. Carbon monoxide is a toxic gas that is produced by burning fuels and is not a normal part of the respiratory process. Hydrogen is not a waste product of respiration and is not typically exhaled. Therefore, the correct answer is carbon dioxide.Rate this question:

What happens when you breathe in?
- A.
When you breathe in your diaphragm expands and your ribcage contracts.
- B.
When you breathe in your diaphragm contracts and your ribcage expands.
- C.
When you breathe in your diaphragm explodes and your ribcage contradicts.
- D.
When you breathe in your diaphragm does not move and your ribcage expands.
Correct Answer
B. When you breathe in your diaphragm contracts and your ribcage expands.Explanation
When you breathe in, the diaphragm contracts and moves downward, creating more space in the chest cavity. This allows the lungs to expand and fill with air. At the same time, the muscles between the ribs contract, causing the ribcage to expand outward. This expansion of the ribcage further increases the space in the chest cavity, allowing more air to enter the lungs. Therefore, when you breathe in, your diaphragm contracts and your ribcage expands.Rate this question:

- B.
The muscles that allow you to breathe in and out is the trachea.
- C.
The muscles that allow you to breathe in and out is the tongue.
- D.
The muscles that allow you to breathe in and out is the diaphragm.
Correct Answer
D. The muscles that allow you to breathe in and out is the diaphragm.Explanation
The diaphragm is a dome-shaped muscle located at the base of the lungs. It plays a crucial role in the process of breathing by contracting and relaxing. When the diaphragm contracts, it flattens and moves downward, increasing the space in the chest cavity and allowing the lungs to expand. This creates a vacuum effect, causing air to rush into the lungs. On the other hand, when the diaphragm relaxes, it moves back up, decreasing the space in the chest cavity and pushing air out of the lungs. Therefore, the diaphragm is responsible for the inhalation and exhalation of air, enabling us to breathe in and out.Rate this question:
