Coloured transmission electron micrograph (TEM) of a section through part of a type II alveolar cell from a dog (Canis familiaris). This cell is found in the alveoli (air sacs) of the lungs. It secretes surfactant, a substance that reduces surface tension in the air sac and prevents it from collapsing. The nucleus (blue), which contains the cell's genetic information, is at right. Nuclear pores in its membrane are pink. The yellow structures are lamellar bodies. These are specialised vesicles that store and transport surfactant.
