Which of these will be seen in our respiratory system ? I. The absence of cartilage in small bronchioles allows them to expand . II. The walls of the alveoli are made of cuboidal epithelium . III. The recoil of the elastic fibres surrounding the alveoli helps to move air out during expiration. IV. The trachea and bronchi are supported by circles of cartilage.
