Question 1

The glottis is ____ when swallowing and ____ when speaking.&#10;A) &#8203;closed; open&#10;B) open; closed&#10;C) rigid; relaxed&#10;D) relaxed; rigid&#10;E) vibrating; closed

Accepted Answer

When swallowing, the glottis needs to be closed to prevent food or liquid from entering the trachea. When speaking, the glottis needs to be open to allow air to pass through the vocal cords and create sound.

Question 2

What is the correct sequence of air flow in mammals?&#10;A) &#8203;nasal cavities, larynx, pharynx, bronchi, trachea&#10;B) nasal cavities, pharynx, bronchi, larynx, trachea&#10;C) nasal cavities, pharynx, larynx, trachea, bronchi&#10;D) nasal cavities, larynx, pharynx, trachea, bronchi&#10;E) nasal cavities, bronchi, larynx, trachea, pharynx

Accepted Answer

The correct sequence of airflow in mammals is nasal cavities, pharynx, larynx, trachea, bronchi, and lungs. Option C is the only one that has this correct sequence. Option A has the incorrect sequence of bronchi and trachea, option B has the incorrect sequence of larynx and bronchi, option D has the incorrect sequence of trachea and bronchi, and option E has the incorrect sequence of bronchi and pharynx.

Question 3

The exchange of oxygen and carbon dioxide occurs in the human lungs in the ____.&#10;A) bronchi&#10;B) alveoli&#10;C) bronchioles&#10;D) trachea&#10;E) glottis

Accepted Answer

The exchange of oxygen and carbon dioxide occurs in the alveoli, which are tiny air sacs in the lungs where gas exchange takes place. The bronchi, bronchioles, trachea, and glottis are all involved in the process of breathing and air flow, but they do not directly facilitate gas exchange.

Question 5

The term &#34;respiration&#34; in animals refers to the ____.&#10;A) &#8203;movement of oxygen into an animal only&#10;B) movement of carbon dioxide out of an animal only&#10;C) movement of oxygen into an animal and the movement of carbon dioxide out of the animal&#10;D) binding of oxygen to hemoglobin molecules in the blood&#10;E) diffusion of oxygen across a cell membrane

Accepted Answer

Respiration in animals refers to the movement of oxygen into an animal and the movement of carbon dioxide out of the animal. This process occurs through breathing, where oxygen is inhaled and carbon dioxide is exhaled. The respiratory system, which includes the lungs and airways, is responsible for this exchange of gases.
