B) homologous
C) remedial
D) vestigial
Answer:
The correct answer would be B) homologous.
Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.
For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy. They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).
These organs are adapted to perform different functions in an environment.
It is also observed that these organs developed in the same manner in the embryo and from similar origins.
Gas exchange in the respiratory system occurs in the alveoli, which are small air sacs located in the lungs. Oxygen diffuses from the alveoli to the capillaries, while carbon dioxide diffuses from the capillaries to the alveoli.
Gas exchange in the respiratory system takes place in the alveoli, which are small air sacs located at the ends of the respiratory bronchioles. These structures are found within the lungs. The alveoli are surrounded by capillaries, which are tiny blood vessels.
When we breathe in, oxygen from the air enters the alveoli and diffuses across the thin walls of the alveoli and capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be removed when we exhale.
So, the gas exchange occurs between the alveoli and the capillaries surrounding them.
