can/ability/capability：
can，既可以描述主观可能性，也可以描述客观可能性。比如，可以说bird can fly, but you can't.
be able to，多用于人和生物的能力，不用于描述客观事物的能力。 比如说，天能下雨也能下雪，it can rain and snow，但不能说，it is able to rain and snow。
be capable of可以同时描写人和物的能力，但多用与描写事物的能力。比如，the train is capable of carring 100 people.；I am capable of building up a plant for cars.有能力建立一个汽车工厂。
ability to do sth，做某事的能力
capability to do sth；capability of doing sth
本题“respiratory system's ability”是把呼吸系统视同为人/生物，所以用表示人/生物的能力的词语：ability
