Final answer:
The isthmus is the part of the uterus where the fallopian tubes attach, and the wide distal part of each tube, which helps guide eggs into the tubes, is called the infundibulum.
Step-by-step explanation:
The area where the two fallopian tubes attach to the uterus is known as the isthmus, which is the narrow medial portion that joins the uterus. The fallopian tubes, also referred to as oviducts or uterine tubes, are essential components of the female reproductive system. They serve as the passage for oocytes (eggs) from the ovaries to the uterus. Each tube ends with a wide distal part called the infundibulum, characterized by slender projections known as fimbriae, which help guide the oocytes into the tubes. Fertilization typically occurs within the fallopian tubes, specifically in the ampulla, the middle region of the tube.
