Types of Respiration System (4)

Biology

Adaptation of fish filaments (3)

The lamella membrane is thin and supplied with many blood capillaries for easy absorption and transport of oxygen and carbon dioxide

The frog respiratory structure

Are skin and lungs

Adaptation of the frog's respiratory structure which is the skin (1)

The skin is thin and highly permeable to respiratory gases

Adaptation of the frog's respiratory structure which is the skin (2)

The moist skin allows respiratory gases to dissolve in it

Adaptation of the frog's respiratory structure which is the skin (3)

Beneath the skin, there are many networks of blood capillaries to transport respiratory gases

Adaptation of the frog's respiratory structure which is the lungs (1)

The surface of the lungs is folded to increase the total surface area for the exchange of gases

Adaptation of the frog's respiratory structure which is the lungs (2)

The thin lung membrane eases the diffusion of respiratory gases

Adaptation of the frog's respiratory structure which is the lungs (3)

The moist lung walls enable respiratory gases to dissolve in them

Adaptation of the frog's respiratory structure which is the lungs (4)

The lungs are also rich with a network of blood capillaries to transport respiratory gases

The human respiratory structure

Is the alveolus
