When a tubal ligation done after a c-section, is a chunk of the falopian tube removed creating a gap between ovary and remaining tube?

Fallopian tube: I am very surprised that your doctor has not discussed this in detail. You must discuss this some more with your Gynecologist!

Explanations : As you should know that this procedure usually performed to prevent pregnancy. No otherwise influence on the body functions.

Various techniques: There are a variety of techniques to performing a tubal ligation during a c section. The most common is a mid segmental salpingectomy - This is where the middle section of the tube is removed completely. Recently some doctors are removing the entire tube as some studies show a reduction in the lifetime risk of ovarian cancer when the tube is removed.
