BIOLOGY February Exam 7A

Process in which we take oxygen from the air and expel carbon dioxide produced in the cells.

• Respiration    

• Cellular respiration

• Difussion

How many phases of respiration are?

• 2

• 3

• 4

In this phase the gases are exchanged in the blood:

• cellular respiration

• internal respiration

• external respiration

• breathing

Stage called air channeling:

• cellular respiration

• internal respiration

• external respiration

• breathing

Nose, larynx, pharynx, traquea and brochi are called:

• airway

• pulmonary system

• internal organs

Tiny bags of air found at the end of the bronchial  tubes, in which gases are exchanged for oxygen in the blood

• alveoli

• pulmonary system

• internal organs

Bronchioli, alevoli and capillaries conformed the:

• alveoli

• pulmonary system

• internal organs

Process through which gases or substances pass from one side of a membrane to the other.

• Respiration    

• Cellular respiration

• Difussion

Small flap that stops food and liquid from going into airway:

• larynx

• bronchioles

• epiglottis

Small conduits that divide the lungs and conduct air into the pulmonary alveoli:

• larynx

• bronchioles

• epiglottis
