Put the following activities that take place in pulmonary respiration in the correct order:

Compare to humanHow does pulmonary respiration differ in humans?

The nares are sealed and the floor of the mouth cavity is raised The frog forms a pocket of air under its tongue The frog closes and lowers the floor of its mouth,pulling air through the nares. The glottis opens, allowing the air in the lungs to exit The air under the tongue is forced into the lungs

13

Describe the movement of oxygen and carbon dioxide between the environment and the tissues of the body, using pulmonary respiration.

Fill in the blanks in the following paragraph with the following words or phrases:

cellular respiration respiration gas exchange

Respiration is a sequence of events that transports oxygen from the environment to the body tissues, and removes waste carbon dioxide from the body tissues to the environment. One part of this process is the diffusion of oxygen and carbon dioxide into and out of the capillaries.

This is calledd , and takes place primarily in the lungs and body tissues.

The oxygen acquired by the body is used to produce energy in the process of cellular respiration .
