The surface area of the lungs is roughly the same size as:
-
A Tennis Court
-
A Football Field
-
A Basketball Court
-
A Baseball Field
Correct Answer
A. A Tennis CourtExplanation
The surface area of the lungs is roughly the same size as a tennis court. This comparison suggests that the lungs have a large surface area, similar to the dimensions of a tennis court. It helps to visualize the extensive network of tiny air sacs (alveoli) present in the lungs, which allow for efficient gas exchange. The comparison also highlights the importance of the lungs in facilitating respiration and oxygenation of the blood.Rate this question:

On average, the inside of the nose makes enough mucus every day to fill...
-
Two egg cups
-
Four egg cups
-
Three egg cups
-
One egg cup
Correct Answer
A. Two egg cupsExplanation
The inside of the nose produces enough mucus every day to fill two egg cups. Mucus is a sticky substance that helps to moisturize and protect the nasal passages. It traps dust, bacteria, and other particles, preventing them from reaching the lungs. The production of mucus is a natural process that keeps the nasal passages moist and helps to maintain proper respiratory function.Rate this question:

How many times do we breathe everyday?
-
20,000
-
15,000
-
10,000
-
25,000
Correct Answer
A. 20,000Explanation
The average person breathes approximately 20,000 times a day. Breathing is an essential bodily function that supplies oxygen to our cells and removes carbon dioxide. Each breath involves inhaling and exhaling, and this process is repeated throughout the day. The respiratory system automatically regulates our breathing rate based on the body's needs, which can vary depending on factors such as physical activity and stress levels. Therefore, the correct answer is 20,000 breaths per day.Rate this question:

The human lung has approximately how many alveoli?
-
300 to 400 million
-
600 to 800 million
-
800 to 900 million
-
400 to 600 million
Correct Answer
A. 300 to 400 millionExplanation
The human lung contains approximately 300 to 400 million alveoli. Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place during respiration. These numerous alveoli provide a large surface area for efficient gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.Rate this question:

The amount of air that always stays in the lungs is...
-
2 Liters
-
0.5 Liters
-
3 Liters
-
1 Liter
Correct Answer
A. 1 LiterExplanation
The amount of air that always stays in the lungs is 1 liter. This is known as the residual volume, which is the amount of air that remains in the lungs even after a forceful exhale. It helps to keep the lungs inflated and prevents them from collapsing completely. This residual volume ensures that the lungs are always partially filled with air, allowing for efficient gas exchange and maintaining the structural integrity of the lungs.Rate this question:

The highest recorded sneeze speed is...
-
80 mph
-
100 mph
-
120 mph
-
113 mph
Correct Answer
A. 100 mphExplanation
The highest recorded sneeze speed is estimated to be around 100 miles per hour (160.9 kilometers per hour). When a person sneezes, a sudden and forceful release of air, mucus, and particles occurs from the respiratory system. The speed of a sneeze can vary from person to person and even from one sneeze to another, but it can be quite fast, especially if it's a powerful sneeze. This estimate is based on observations and measurements of sneezes.Rate this question:

The amount of water we lose every day through breathing is:
-
1 Liter
-
1.5 Liters
-
0.5 Liters
-
2 Liters
Correct Answer
A. 0.5 LitersExplanation
The correct answer is 0.5 Liters because when we breathe, we exhale moisture in the form of water vapor. On average, an adult loses about 0.5 liters of water per day through respiration. This loss can increase during activities that cause heavy breathing, such as exercise or being in a hot environment.Rate this question:

On average, how many pounds of dust does a person inhale in a lifetime?
-
40
-
46
-
44
-
42
Correct Answer
A. 44Explanation
On average, a person inhales about 44 pounds of dust in their lifetime. This is because dust particles are constantly present in the air, and we inhale them with every breath. Over the course of a lifetime, this adds up to approximately 44 pounds.Rate this question:

The primary chemical stimulus for breathing is the concentration of...
-
Carbon dioxide in the blood
-
Carbon monoxide in the blood
-
Carbonic acid in the blood
-
Oxygen in the blood
Correct Answer
A. Carbonic acid in the bloodExplanation
The primary chemical stimulus for breathing is the concentration of carbonic acid in the blood. Carbonic acid is formed when carbon dioxide reacts with water in the blood, and it plays a crucial role in maintaining the pH balance of the body. When carbonic acid levels increase, it triggers the respiratory center in the brain to stimulate breathing, allowing the body to eliminate excess carbon dioxide and maintain proper pH levels. Oxygen levels in the blood also influence breathing, but carbonic acid is the primary chemical stimulus.Rate this question:
