Respiration (Gas Exchange)

Question 1

Also referred to as Respiratory Exchange or Respiration, is the process of organisms acquiring oxygen (O2) from the environment and releasing carbon dioxide (C02) in animals and vice versa for plants.

Answer 1

Gas Exchange

Question 2

Function of Gas Exchange

Answer 2

acquire oxygen and release carbon dioxide and is mostly associated with the circulatory system

Question 3

Respiration of Fishes:

Answer 3

Gills

During inhalation, the mouth of the fish opens and the gills are closed. During exhalation, the mouth of the fish is closed and the gills are open.

Question 4

Respiration of Annelids:

Answer 4

Through Skin

Question 5

Respiration of Vertebrate:

Answer 5

Lungs/alveoli

Question 6

Respiration of Insects:

Answer 6

Tracheal system (independent of the animals’ open circulatory system)

Question 7

Recite the ROUTE OF AIR through the respiratory system

Answer 7

nose → nasal cavity → pharynx → larynx → trachea → bronchi → bronchioles → alveoli

Question 8

A chronic inflammatory disease that causes breathing problems due to narrowed airways from inflammation or mucus blockage.

Answer 8

Asthma

Question 9

Sacs (alveoli) lose elasticity and become damaged, reducing the lung’s ability to transfer oxygen to the blood.

Answer 9

Emphysema

Question 10

Caused by Mycobacterium tuberculosis, spreads through airborne germs from person to person.

Answer 10

Tuberculosis
