Which term is associated with the jejunum?

The term that is associated with the jejunum is "jejun/o." This root word specifically refers to the jejunum, which is the middle section of the small intestine, situated between the duodenum and the ileum.

Understanding medical terminology often involves recognizing the root words that signify specific organs or parts of the body. In this case, "jejun/o" directly indicates a connection to the jejunum. This term is commonly used in medical contexts to describe conditions, procedures, or anatomical discussions regarding this particular section of the digestive system.

The other choices provided do not relate to the jejunum; they instead refer to different anatomical structures or medical concepts. For example, "isch/i" pertains to the ischium or related concepts of ischemia, "irid/o" refers to the iris of the eye, and "kal/i" relates to potassium. Each of these root words serves a unique purpose in medical vocabulary, but none connects to the jejunum as "jejun/o" does.
