Human Anatomy & Physiology: The Respiratory System 1
I created these quizzes to help me study for my A&P exams. This is the first quiz dealing with the respiratory system.
Questions and Answers
- 1.
Another term for breathing is _____________. These terms simply mean movement of _____ in and out of the ______.
Explanation
Breathing is commonly known as pulmonary ventilation, which refers to the process of air movement in and out of the lungs. The term "pulmonary" specifically relates to the lungs. Therefore, the correct answer is pulmonary ventilation, air, lungs.Rate this question:

Respiration refers to the entire process by which gases are exchanged between the ________ and _________.
- A.
Lungs; blood
- B.
Blood; body cells
- C.
Atmosphere; body cells
- D.
Lungs; body cells
- E.
Atmosphere; lungs
Correct Answer
C. AtmospHere; body cellsExplanation
Respiration is the process of exchanging gases between the atmosphere and the body cells. The lungs are responsible for exchanging gases between the atmosphere and the blood, while the blood transports these gases to the body cells. Therefore, the correct answer is "lungs; body cells".Rate this question:

External respiration refers to the exchange of gases between the ________ and __________.
- A.
Lungs; blood
- B.
Blood; body cells
- C.
Atmosphere; body cells
- D.
Lungs; body cells
- E.
Atmosphere; blood
Correct Answer
A. Lungs; bloodExplanation
External respiration is the process of exchanging gases between the lungs and the blood. Oxygen from the inhaled air enters the bloodstream in the lungs, while carbon dioxide, a waste product, is removed from the blood and exhaled out of the body. This exchange of gases is essential for maintaining proper oxygen levels in the blood and removing waste products.Rate this question:

Internal respiration refers to the exchange of gases between the _______ and ________.
- A.
Lungs; blood
- B.
Blood; body cells
- C.
Atmosphere; body cells
- D.
Lungs; body cells
- E.
Atmosphere; blood
Correct Answer
B. Blood; body cellsExplanation
Internal respiration refers to the exchange of gases between the blood and body cells. This process occurs in the capillaries, where oxygen from the blood diffuses into the body cells, and carbon dioxide, a waste product of cellular respiration, diffuses from the body cells into the blood. The oxygen is then transported to the body cells for energy production, while the carbon dioxide is carried back to the lungs to be exhaled. Therefore, the correct answer is "blood; body cells".Rate this question:

The exchange between gases during external respiration takes place in the ________.
- A.
Lungs
- B.
Alveoli
- C.
Body cells
- D.
Bronchioles
- E.
Pleural cavity
Correct Answer
B. AlveoliExplanation
During external respiration, the exchange of gases, specifically oxygen and carbon dioxide, occurs between the lungs and the bloodstream. The alveoli, which are tiny air sacs located in the lungs, play a crucial role in this process. Oxygen from the inhaled air diffuses into the bloodstream through the thin walls of the alveoli, while carbon dioxide, a waste product, moves from the bloodstream into the alveoli to be exhaled. Therefore, the alveoli are the site where the exchange of gases takes place during external respiration.Rate this question:

When oxygen is utilized by the cells in order to liberate energy from food molecules, it is known as:
- A.
Respiration
- B.
Cellular respiration
- C.
External respiration
- D.
Internal respiration
- E.
Digestion
Correct Answer
B. Cellular respirationExplanation
Cellular respiration refers to the process in which cells use oxygen to break down food molecules and release energy. This process occurs within the cells themselves, hence the term "cellular" respiration. The other options mentioned, such as external respiration and internal respiration, refer to the exchange of gases between the body and the environment or within the body, respectively, but they do not specifically describe the utilization of oxygen by cells to produce energy. Digestion, on the other hand, is the process of breaking down food into smaller molecules that can be absorbed and used by the body, but it does not involve the use of oxygen.Rate this question:

During cellular respiration, ____________ is given off as a waste product.
- A.
Oxygen
- B.
Nitrogen
- C.
Hydrogen
- D.
Carbon dioxide
- E.
Carbon monoxide
Correct Answer
D. Carbon dioxideExplanation
During cellular respiration, carbon dioxide is given off as a waste product. This is because cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP. In this process, glucose is oxidized and carbon dioxide is produced as a byproduct. Carbon dioxide is then released from the cells and transported to the lungs, where it is exhaled as a waste product.Rate this question:

________ of the __________ cells in the respiratory tract will assist in the removal of ________.
Correct Answer
cilia, epithelial, microbesExplanation
The cilia, which are tiny hair-like structures, located on the epithelial cells in the respiratory tract, play a crucial role in removing microbes. These cilia beat in coordinated motions, creating a wave-like movement that helps to sweep away and expel microbes, such as bacteria and viruses, from the respiratory tract. This mechanism is an important defense mechanism of the respiratory system to prevent infections and maintain respiratory health.Rate this question:
- 9.
Production of sounds involved in speaking involves the ____________.
Correct Answer
true vocal chordsExplanation
The correct answer is true vocal chords. The production of sounds involved in speaking is primarily carried out by the true vocal chords. These vocal chords are located in the larynx and vibrate when air passes through them, producing sound waves. The vocal chords can be manipulated to create different pitches and tones, allowing for the formation of words and speech.Rate this question:

Olfactory sensation to the central nervous system refers to ____________.
- A.
Sense of taste
- B.
Sense of smell
- C.
Sense of touch
- D.
Sight
- E.
Hearing
Correct Answer
B. Sense of smellExplanation
The olfactory sensation refers to the sense of smell. It is the ability to detect and perceive odors through the olfactory system, which includes the olfactory receptors in the nose and the pathway that transmits the information to the brain. The central nervous system receives and processes these olfactory signals, allowing us to identify and interpret different smells.Rate this question:

Review: What are the five general functions of the respiratory system.
Correct Answer
breathing, respiration, defense, speaking and smellExplanation
The five general functions of the respiratory system are breathing, respiration, defense, speaking, and smell. Breathing refers to the process of inhaling and exhaling air, while respiration involves the exchange of oxygen and carbon dioxide in the body. Defense refers to the respiratory system's role in protecting the body from harmful substances in the air. Speaking is facilitated by the respiratory system's ability to control airflow through the vocal cords. Lastly, the respiratory system enables the sense of smell by allowing the detection of airborne chemical substances.Rate this question:
