Term information

curator notes

not every anatomical conduit is a tube - for example, a bone foramen is an opening in the bone, and there is no distinct separate tube structure. Tubes may transport large mixed objects (for example, a bolus of food in the digestive tube) or they may transport the secretions of a single gland (for example, gland ducts)
