Description
Light micrograph of a breathing pore (spiracle) on the thorax of a silkworm (Bombyx mori). This opening is fringed with hairs for filtration. Air passes into the pore and is conveyed through the body by a network of tubes called tracheae which branch into smaller tubes called tracheoles. In insects, oxygen is not carried in the blood but diffuses across these tracheal tubes directly into each cell. Tracheae are ingrowths of the body wall made of chitin. Magnification is x60 at 35mm.
