How Does Human Physiology - Hormonal Changes during Pregnancy Work?

Pregnancy is like having a super team inside your body that works together to grow a new person.

When you're pregnant, your body makes special messengers called hormones, and these messengers help everything grow and change so the baby can be healthy. It’s like having a group of friends who all have different jobs, and they talk to each other to make sure everything goes smoothly.

The hormone squad includes estrogen, progesterone, and human chorionic gonadotropin (hCG), each has its own job.

• Estrogen helps the baby grow and makes your body get ready for birth.
• Progesterone is like a cozy blanket that keeps everything calm and safe inside you.
• hCG is what makes your morning sickness happen, kind of like when you're really excited about something new, it can make your tummy feel funny.

These hormones work together all day long to keep the baby growing and help your body change so both you and the baby stay happy.
