How A Woman's Organs Move Around During Pregnancy?

From extreme fatigue and nausea to aches and stretch marks, it’s no secret that women put up with a lot when they are pregnant. An animation shows how a woman’s internal organs have to make sacrifices and adjust to make space for a growing baby.
 
It shows the changes from conception to the point of birth when organs are squeezed, the heart works harder and the baby presses upon the bladder, causing discomfort.
 
The interactive tool, produced by the Chicago Museum of Science and Industry, tracks internal changes throughout the three trimesters over the 40-week period. 
 
It shows the hormonal changes in the first trimester that affect almost every organ in the body, causing many women to have strange cravings for food, nausea, and be extremely tired.
