Step-by-step explanation:
The Chadwick, Goodell, and Hegar signs are characteristics observed in the female reproductive system during pregnancy. They occur in a specific order and can be used to determine the progress of pregnancy:
- The Chadwick sign refers to the bluish discoloration of the cervix, vagina, and vulva due to increased blood flow.
- The Goodell sign is the softening of the cervix caused by increased vascularity and elevated levels of estrogen.
- The Hegar sign is the softening and compressibility of the lower uterus, which can be felt during a pelvic examination.
