The Bulldogs (23-9) will be seeking their sixth consecutive trip to the regional semifinals when they play the region's top seed, North Carolina, on Tuesday. The top-seeded Tar Heels dispatched 16th-seeded Bucknell 85-50 earlier Sunday.
Angel Robinson led the eighth-seeded Bulldogs with 17 points and 11 rebounds, and Houts and Megan Darrah each scored 13. Houts also had 12 assists, while Humphrey finished with 12 points and 11 rebounds.
Kristi Smith led Iowa (21-11) with 17 points and Wendy Ausdemore had 16, but the Hawkeyes ran out of steam in a back-and-forth game. There were 11 lead changes in the second half.
Iowa led 31-25 at halftime, but Georgia opened the half on an 11-3 run to go ahead 36-34 with 14:08 to play. The Bulldogs didn't again lead by more than three until the final minute.
It was knotted for the sixth time when Humphrey, a four-time all-Southeastern Conference selection, made a baseline turnaround jumper from about 10 feet with 58 seconds to play. Then Houts, who played all 40 minutes, sealed it at the line.
Georgia will bring a 5-0 career mark against North Carolina into the second round.
Iowa, which shared the Big Ten regular season title with Ohio State, was outscored 12-4 at the free-throw line, and was outrebounded 43-32. Johanna Solverson, Iowa's third-leading scorer, missed 11 of 13 shots.
The game was delayed for several minutes with 14:18 to play when a cheerleader from Georgia had to be carried off the court after landing hard on her back.
The cheerleader, identified as Christine Conley, was down for several minutes before she was placed on a backboard and wheeled away on a stretcher.
