What helps the lungs with air?
- A.
Nerves
- B.
Oxygen
- C.
Diaphragm
- D.
Function
- E.
Cell
Correct Answer
C. DiaphragmExplanation
The diaphragm is a dome-shaped muscle located at the bottom of the lungs. It plays a crucial role in the process of breathing by contracting and relaxing. When the diaphragm contracts, it moves downward, creating more space in the chest cavity and allowing the lungs to expand. This expansion creates a vacuum effect, causing air to rush into the lungs. When the diaphragm relaxes, it moves upward, pushing air out of the lungs. Therefore, the diaphragm helps the lungs with the intake and release of air during the breathing process.Rate this question:

What lets the blood in and out of the heart?
- A.
Oxygen
- B.
Nerves
- C.
Heart
- D.
Valves
- E.
Cell
Correct Answer
D. ValvesExplanation
Valves are responsible for allowing blood to flow into and out of the heart. These one-way valves open and close to ensure that blood moves in the correct direction. When the heart contracts, the valves open, allowing blood to be pumped out. When the heart relaxes, the valves close, preventing blood from flowing back into the heart. This allows for efficient blood circulation throughout the body.Rate this question:

What is the job of the lungs?
- A.
To bring food to the stomach
- B.
Give fresh oxygen to the blood
- C.
Clean and feed the cells
- D.
Help the blood travel in the body
- E.
Send messages to the body
Correct Answer
B. Give fresh oxygen to the bloodExplanation
The job of the lungs is to give fresh oxygen to the blood. Lungs are responsible for the process of respiration, where oxygen from the air is taken in and carbon dioxide is expelled. Oxygen is then transferred from the lungs to the bloodstream, where it binds to red blood cells and is transported to all the cells in the body. This oxygen is necessary for the cells to produce energy through cellular respiration. Therefore, the lungs play a crucial role in providing oxygen to the blood, which is essential for the functioning of the body.Rate this question:

Muscles work in pairs. When one muscle is contracting what does the other muscle do?
- A.
Get up and dance
- B.
Relaxing
- C.
Ride a horse
- D.
Fish
- E.
Contracts too
Correct Answer
B. RelaxingExplanation
When one muscle is contracting, the other muscle in the pair relaxes. This is because muscles work in pairs to create movement. When one muscle contracts, it shortens and pulls on the bone, causing movement. At the same time, the opposite muscle in the pair relaxes and lengthens, allowing the movement to occur smoothly. This coordinated action of muscle pairs is essential for proper movement and functioning of the body.Rate this question:

A special job that an organ does is called what
- A.
Cycle
- B.
Function
- C.
Contracting
- D.
Circluation
- E.
Nerves
Correct Answer
B. FunctionExplanation
The correct answer is "function." In the context of the question, a special job that an organ does is referred to as its function. The term "cycle" does not accurately describe the job of an organ, while "contracting" and "circulation" are specific actions performed by certain organs rather than describing their overall job. "Nerves" are not directly related to the job of an organ. Therefore, "function" is the most appropriate term to describe the special job of an organ.Rate this question:

- E.
Toe
Correct Answer
A. EsophagusExplanation
The correct answer is esophagus. The esophagus is a tube that connects the throat to the stomach. It is responsible for transporting food from the mouth to the stomach through a series of muscle contractions known as peristalsis. The esophagus plays a crucial role in the digestive system by allowing food to reach the stomach for further digestion and absorption of nutrients.Rate this question:

How long does it take chewn food to reached the stomach?
- A.
10 minutes
- B.
10 seconds
- C.
10 hours
- D.
10 days
- E.
10 years
Correct Answer
B. 10 secondsExplanation
Chewed food reaches the stomach in approximately 10 seconds. The process of swallowing pushes the chewed food down the esophagus and into the stomach through a muscular valve called the lower esophageal sphincter. This valve opens for a brief moment to allow the food to pass through. Once in the stomach, the food is further broken down and mixed with stomach acid and enzymes to begin the digestion process.Rate this question:
