This part of the respiratory system that delivers oxygen to your CELLS is called?
-
Windpipe
-
Bronchi
-
Alveoli
-
Lungs
Correct Answer
A. AlveoliExplanation
The alveoli are tiny air sacs in the lungs where oxygen is exchanged for carbon dioxide. This is where the respiratory system delivers oxygen to the cells in the body. Oxygen from the air we breathe enters the alveoli and diffuses into the blood vessels surrounding them, which then carries the oxygen to the cells throughout the body. The alveoli provide a large surface area for efficient gas exchange and play a crucial role in delivering oxygen to the cells.Rate this question:

When you breathe in the air passes down your windpipe into your __________ then out to the Alveoli which delivers oxygen to your cells.
-
Lungs
-
Windpipe
-
Bronchi
-
Alveoli
Correct Answer
A. BronchiExplanation
The bronchi are the tubes that branch off from the windpipe and lead into the lungs. They carry air into the lungs, where it is then distributed to the alveoli. The alveoli are tiny air sacs in the lungs where oxygen is exchanged for carbon dioxide, allowing oxygen to be delivered to the cells in the body. Therefore, the bronchi play a crucial role in the process of delivering oxygen to the cells.Rate this question:

Breathing in and out is assisted by the what??
-
Diaphragm
-
Toes
-
Nose
-
Ribs
Correct Answer
A. DiaphragmExplanation
The diaphragm is a dome-shaped muscle located beneath the lungs that plays a crucial role in the process of breathing. When we inhale, the diaphragm contracts and flattens, creating more space in the chest cavity and allowing the lungs to expand and fill with air. As we exhale, the diaphragm relaxes and moves back up, pushing the air out of the lungs. Therefore, the diaphragm assists in the movement of air in and out of the lungs during the process of breathing.Rate this question:

Your rib cage has how many pairs of ribs?
-
9
-
10
-
11
-
12
Correct Answer
A. 12Explanation
The rib cage consists of 12 pairs of ribs. Each pair of ribs is attached to the spine at the back and to the sternum at the front, forming a protective cage around the vital organs in the chest. The ribs play a crucial role in protecting the heart, lungs, and other organs from injury.Rate this question:

Intercostal muscles are the muscle tissue between your what?
-
Nose
-
Ears
-
Ribs
-
Toes
Correct Answer
A. RibsExplanation
Intercostal muscles are the muscle tissue between your ribs. These muscles play a crucial role in the process of breathing by expanding and contracting the ribcage, allowing for the movement of the chest during respiration. They help in the inhalation and exhalation of air by assisting in the elevation and depression of the ribcage, facilitating the expansion and contraction of the lungs.Rate this question:

True or False..... Your right lung is slightly larger than your left.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement is true. The right lung is slightly larger than the left lung. This is because the right lung has three lobes while the left lung has only two lobes. Additionally, the right lung needs to accommodate the position of the heart, which is located slightly to the left side of the chest. Therefore, the right lung expands further into the chest cavity compared to the left lung.Rate this question:

Your right lung has three lobes and your left lung has how many?
-
Two
-
Six
-
Eighteen
-
Two hundred
Correct Answer
A. TwoExplanation
The left lung has two lobes. The right lung has three lobes, while the left lung has only two lobes.Rate this question:

True or False... The volume of air going into and out of your lungs is called your lung capacity.
-
True
-
False
Correct Answer
A. TrueExplanation
The volume of air going into and out of your lungs is indeed called your lung capacity. Lung capacity refers to the maximum amount of air that your lungs can hold. It is determined by various factors such as age, sex, height, and overall lung health. Lung capacity can be measured using a spirometer, which is a device that measures the amount and speed of air that is breathed in and out. By measuring lung capacity, healthcare professionals can assess lung function and diagnose respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).Rate this question:

You only use about 1/3rd of your lung ________ when you breathe.
-
Lovers
-
Lobsters
-
Capacity
-
Earrings
Correct Answer
A. CapacityExplanation
When you breathe, you only use about 1/3rd of your lung capacity. Lung capacity refers to the maximum amount of air that your lungs can hold. This means that even during deep breaths, you are not utilizing your lungs to their full potential.Rate this question:

The part of the brain that controls respiration is called the what?
-
Intercosal Muscles
-
Rib Cage
-
Air sacs
-
Mendulla Oblogata
Correct Answer
A. Mendulla OblogataExplanation
The medulla oblongata is a part of the brainstem that controls various involuntary functions, including respiration. It regulates the rate and depth of breathing by sending signals to the muscles involved in respiration, such as the diaphragm and intercostal muscles. This region also contains specialized cells called respiratory centers that monitor the levels of oxygen and carbon dioxide in the blood and adjust breathing accordingly. Therefore, the medulla oblongata is responsible for controlling respiration in the body.Rate this question:

Hiccups and a side ache are both irritations of the what?
-
Diaphragm
-
Windpipe
-
Bronchi
-
Alveoli
Correct Answer
A. DiaphragmExplanation
Hiccups and a side ache are both irritations of the diaphragm. The diaphragm is a dome-shaped muscle that plays a crucial role in the process of breathing. Hiccups occur when the diaphragm contracts involuntarily, causing a sudden intake of breath that is then blocked by the closure of the vocal cords, resulting in the characteristic "hic" sound. A side ache, also known as a stitch, is a sharp pain felt on the side of the abdomen, often caused by the diaphragm becoming irritated or strained during physical activity.Rate this question:

True or False...... bronchitits, pneumonia, pleurisy and asthma are all lung issues.
-
True
-
False
Correct Answer
A. TrueExplanation
Bronchitis, pneumonia, pleurisy, and asthma are all lung issues because they involve inflammation or infection of the respiratory system. Bronchitis is the inflammation of the bronchial tubes, pneumonia is an infection that inflames the air sacs in the lungs, pleurisy is the inflammation of the lining around the lungs, and asthma is a chronic condition that causes inflammation and narrowing of the airways. Therefore, all of these conditions directly affect the lungs and respiratory function.Rate this question:
