Takeaways

• 🌱 The development of a fetus is an extraordinary process that occurs from week to week during pregnancy.
• 🤰 The first week involves fertilization, where the egg and sperm unite to form a zygote, which will become the embryo.
• 📈 By the second week, the embryo has about 150 cells and begins to form layers that will develop into various organs and body systems.
• 🔗 In the third week, the embryo successfully implants into the uterine wall and starts to form the placenta.
• ❤️ By the fourth week, the heart has formed and is functioning, with blood vessels in place.
• 👐 At week five, the embryo's hands start to develop, and the brain and nervous system structures are taking shape.
• 👣 By the sixth week, the embryo's size is comparable to a lentil, and the digestive system begins to form.
• 👁️‍🗨️ At week seven, the embryo can show reflexes and the facial features become more human-like.
• 🧠 By week eight, the embryo is referred to as a fetus, with more defined facial features such as eyes and nose.
• 👶 At week nine, the fetus can open its mouth, and the vocal cords begin to form, indicating the start of potential vocalization.
• 🦴 From week 12 onwards, the fetus's organs continue to develop and mature, with bones becoming more solid and the fetus starting to urinate.
• 👂 At around week 20, the fetus can hear and respond to sounds, and the mother may start to feel movements.
• 🌐 By week 23-26, the fetus's pancreas is working effectively, and the lungs are maturing, increasing the chances of survival if born prematurely.
• 👶‍♂️ At week 27-31, most fetuses are considered viable, with organs and systems nearly matured for life outside the womb.
• 🏆 By week 37-40, the fetus is fully developed and ready for birth, with all organs formed and functioning properly.

At what stage does the embryo successfully implant into the uterus?

The embryo successfully implants into the uterus during the third week of pregnancy.

By the fourth week of pregnancy, what vital organ has formed and started to function?

By the fourth week, the heart has formed and started to function, with blood vessels beginning to carry blood.

When do the hands and feet of the fetus start to form?

The hands and feet of the fetus start to form during the fourth week of pregnancy.

What is the approximate size of the embryo at the end of the sixth week?
