Chapter 22 Biology 102 Practice Quiz on Respiration

Top > Science > Biology

1 Comment

Welcome to the biology practice quiz, useful for your review of classroom and textbook material. Specifically, this quiz focuses on respiration/breathing!

Respiration is the process by which an organism exchanges gases with its environment. It is the reverse of photosynthesis. How well do you understand this biological function?

What is the Diaphragm?
- Separates the abdominal cavity from the thoracic cavity and helps ventilate the lungs.
- Are specialized secretions required to keep the walls of the small alveoli from sticking shut.
- A condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
- The volume of air breathed during maximal inhalation and exaltation.
What are the Surfactants?
- Specialized secretions required to keep the walls of the small alveoli from sticking shut.
- A condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
- The volume of air breathed during maximal inhalation and exaltation.
- The volume of air still remaining in the lungs after the most forcible expiration possible.
What is Emphysema?
- Separates the abdominal cavity from the thoracic cavity and helps ventilate the lungs.
- A condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
- When the rib cage expands, the diaphragm moves downward, the pressure around the lungs decreases, and air is drawn into the respiratory tract.
- Is used by almost all vertebrates and many invertebrates and transports oxygen, buffers blood, and transports CO2 .
Negative pressure breathing is when?
- The volume of air still remaining in the lungs after the most forcible expiration possible.
- The volume of air breathed during maximal inhalation and exaltation.
- When the rib cage expands, the diaphragm moves downward, the pressure around the lungs decreases, and air is drawn into the respiratory tract.
- A condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
The volume of air breathed during maximal inhalation and exaltation.
- Emphysema
- Negative pressure breathing
- Residual volume
- Vital capacity
What is the Residual volume?
- Is the ability of the eyes to distinguish fine detail.
- The volume of air breathed during maximal inhalation and exaltation.
- The volume of air still remaining in the lungs after the most forcible expiration possible.
- Are specialized secretions required to keep the walls of the small alveoli from sticking shut.
Is used by almost all vertebrates and many invertebrates and transports oxygen, buffers blood, and transports CO2 .
- Emphysema
- Hemoglobin
- Residual volume:
- Vital capacity
When you hold your breath, which of the following blood gas changes first leads to the urge to breathe?
- rising CO2
- falling CO2
- rising O2
- rising CO2 and falling O2
Countercurrent gas exchange in the gills of a fish?
- Maintains a gradient that enhances diffusion.
- Allows O2 to diffuse against its partial pressure gradient.
- Enables the fish to obtain oxygen without swimming.
- Means that blood and water flow at different rates.
When you inhale the diaphragm?
- Contracts and moves downward.
- Relaxes and moves upward.
- Contracts and moves upward.
- Relaxes and moves downward.
In which of the following organisms does oxygen diffuse directly across a respiratory surface to cells without being carried by the blood
- A sparrow
- A whale
- A grasshopper
- An Earworm
What is the function of the cilia in the trachea and bronchi?
- To sweep mucus with trapped particles up and out of the respiratory tract.
- To increase the surface are for gas exchange
- To sweep air into and out of the lungs.
- To vibrate when air is exhaled to produce sounds.
What do the alveoli of mammalian lungs, the gill filaments of fish, and the tracheal tubes of insects have in common?
- All of the above.
- Use of a circulatory system to transport gases.
- Countercurrent exchange.
- A large, moist surface area for gas exchange
Which of the following is the best explanation for why birds can fly over the himalayas while most humans require oxygen masks to climb these mountains?
- With their one-way flow of air and efficient ventilation, the lungs of birds extract more O2 from the air.
- Human are endotherms and thus require more oxygen than birds, which are ectotherms.
- Birds use positive pressure breathing
- Bird are much smaller and require less oxygen
Of the four types of respiratory organs, which type does not require assistance from a circulatory system for gas exchange?
- The Gills
- The trachea.
- The lungs.
- The skin.
List the structures in the direction of carbon dioxide travel as it leaves the body.
- Nasal cavity, Bronchi, Pharynx, Larynx, Bronchioles, Alveoli, Trachea.
- Nasal cavity, Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli.
- Nasal cavity, Larynx, Bronchi, Trachea, Bronchioles, Alveoli, Pharynx.
- Nasal cavity, Bronchi, Larynx, Trachea, Bronchioles, Pharynx, Alveoli.
Which passageway is shared by both food and air?
- The Trachea
- The Gills
- The Skin
- The Mouth
What is the function of the nasal cavity?
- To keep the air moving to the body.
- To warm, moisturize, and filter air entering the body before it reaches the lungs.
In which of the structures gas exchange occurs across?
- The lungs.
- The trachea
- The Skin
- The Mouth
What is the function of cilia and thin mucus that lines the inner linings of the major branches of our respiratory system?
- To warm, moisturize, and filter air entering the body before it reaches the lungs.
- To help the respiratory passages sweep contaminant-laden mucus up and out of the airways and can be damaged by smoking.
- To help with the exchanging gases in water is that there is no problem keeping the respiratory surface moist.
Which part of the human brain contains the primary breathing control center?
- The medulla oblongata.
- The brain
- The heart
- The lungs
This breathing center directly sense and respond to _____and_____ ?
- pH of blood and cerebrospinal fluid.
- CO2 and mucus
- O2 and stomac
What is the physical process underlying gas exchange?
- fusion of each gas up its partial pressure gradient.
- Diffusion of each gas up its partial pressure gradient.
- Diffusion of each gas down its partial pressure gradient.
How does the fetus exchange gasses with the outside world?
- It does this by way of the amniotic fluids,
- It does this by way of the placenta,
- It does this by way of the Umbilical cord,
- It does this by way of the blood vessels,
What is the placenta?
- A composite organ that includes tissues from both fetus and mother.
- A large network of capillaries.
What contributes to gas exchange in the human fetus?
- A large network of capillaries.
- A small network of capillaries.
- The blood vessels
