Adaptations in Respiratory Systems

Three features to ensure an efficient gaseous exchange with the surrounding

• Dry surface of respiratory structures

• Moist surface of respiratory structures

• Thin respiratory structures

• Thick respiratory structures

• Large surface of respiratory structures

Amphibians can breathe using lung and moist outer skin

• True

• False

Amphibians has thin, moist and surrounded by many

Skin of amphibians always moist because it is covered by a layer of

Under the layer of skin is a dense networks of blood capillaries

• To increase the mass of skin

• To increase the gap between skin and blood capillary

• To increase the rate of diffusion of gas

• To increase the moist of skins

Amphibians breathe through

• Trachea

• Lung

• Moist outer skins

• Stoma

Respiratory structure that increase the efficiency of gaseous exchange in water

Gills are made up of

• Glottis

• Nostril

• Filaments

• Lamellae

Trachea system is the respiratory system of

• Insects

• Fish

• Amphibians

• Mammals

Tracheoles have thin and moist wall to increase the efficiency of gaseous exchange

• True

• False
