Final answer:
The three sections of the uterine tube are the isthmus, ampulla, and infundibulum.
Step-by-step explanation:
The uterine tubes (also called fallopian tubes or oviducts) are divided into three sections. The first section is called the isthmus, which is the narrow medial end connected to the uterus. The second section is the ampulla, which is the middle region of the tube where fertilization often occurs.
The third section is the wide distal end called the infundibulum, which flares out with finger-like projections called fimbriae.
