Intrauterine pregnancy means that the pregnancy (fetus) is inside the uterus where it is supposed to be and not ectopic (in the tubes or anywhere other than the uterus).
An ectopic pregnancy is a non-viable pregnancy that occurs anywhere outside of the uterus. It's often known as a "tubal" pregnancy as ectopics most often occur inside the Fallopian tubes. They can also occur on the cervix, inside the abdominal cavity and outside of the uterus. Ectopic pregnancy if left untreated is life threatening and you should see a Dr immediately.

Pregnancy does not cause inflammation in the uterus. Inflammation of the uterus during pregnancy would serve no biological purpose.
Human normally have single births from a pregnancy, whereas the expanded uterus in cats facilitates multiple births. if your cat is pregnant, the uterus will be greatly enlarged and you may find many fetuses inside.

the uterus
Viable means alive (i.e. there was a heartbeat seen) Intrauterine means 'inside your uterus' (where it should be)
The inside of the uterus is lined with the "endometrium" which is shed every month if you are not pregnant. Once you get pregnant that lining changes to the "decidua" which stays in place because of the hormone progesterone and hCG the pregnancy hormone during pregnancy.
In your uterus
The hormone progesterone in the corpus luteum will prepare the uterus for pregnancy.
