Graded) Latest Questions and Complete Solutions

Questions 1-4 refer to the following passage.Passage

1 - The Respiratory System

The respiratory system’s function is to allow oxygen exchange through all parts of the body.

The anatomy or structure of the exchange system, and the uses of the exchanged gases, varies

depending on the organism. In humans and other mammals, for example, the anatomicalfeatures of the

respiratory system include airways, lungs, and the respiratory muscles.

Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between thegaseous

external environment and the blood. This exchange process occurs in the alveolar region of the lungs.

Other animals, such as insects, have respiratory systems with very simple anatomical features, and iamphibians even the skin plays a vital role in gas exchange. Plants also have respiratory systems but thdirection of gas exchange can be opposite to that of animals.

The respiratory system can also be divided into physiological, or functional, zones. These include the

conducting zone (the region for gas transport from the outside atmosphere to just above the alveoli), the

transitional zone, and the respiratory zone (the alveolar region where gasexchange occurs).

1. What can we infer from the first paragraph in this passage?

a. Human and mammal respiratory systems are the same

b. The lungs are an important part of the respiratory system

c. The respiratory system varies in different mammals

d. Oxygen and carbon dioxide are passive exchanged by the respiratory system

B

We can infer an important part of the respiratory system are the lungs. From the passage, “Molecules of

oxygen and carbon dioxide are passively exchanged, by diffusion, between thegaseous external

environment and the blood. This exchange process occurs in the alveolar region of the lungs.”

Therefore, one of the primary functions for the respiratory system is the exchange of oxygenand carbo

dioxide, and this process occurs in the lungs. We can therefore infer that the lungsare an important part

of the respiratory system.

2. What is the process by which molecules of oxygen and carbon dioxide are passively

exchanged?

a. Transfusion

b. Affusion

c. Diffusion

d. Respiratory confusion

C

The process by which molecules of oxygen and carbon dioxide are passively exchanged isdiffusion. Thi
