Question

How small intestine and lungs are designed to maximize area for transfer of substances?

Answer 1

Answer:

hey mate

Explanation:

Lungs play a major role in the respiratory system. In humans, a pair of lungs are designed in such a way that they are lined by a thin membrane, the smaller tubes called bronchioles a balloon-like structure called alveoli and network of blood capillaries increase the surface area for exchange of gases.

Humans have two lungs and are situated within the thoracic cavity of the chest. They are soft spongy and elastic organ enclosed in a thin membranous sac called the pleura. Lungs are divided into a smaller structure called bronchi which are divided into bronchioles. Alveoli are small, round or balloon-like structure found the end of the bronchioles and provide a larger surface area and maximizes the exchange of gases inside the lungs.

in case of the small intestine there are enough foldings finger like structures which are known as villi

Explanation:

• . the villi increases the surface area which is present in the small intestine for more amount of absorption of the substances. In addition to this the lungs have very thin membrane. The thinner the membrane the more is a diffusion of the substances across it

• as a result of this there is more amount of diffusion of the gases through the  membrane from the alveoli into the blood.
