The birth of the heart.

The Birth of The Heart.. The First thing in mother's womb

“Do they not contemplate the realm of the heavens and earth and all that Allah has created…?” (Al-A’raf 7:185)

A baby's heart begins to beat about 21 to 22 days after fertilization (roughly 5 to 6 weeks of pregnancy). 

This first heartbeat happens before the brain finishes forming and long before the nervous system takes control and continues till we breathe our last.``` 

The heart beats on its own because its early muscle cells can generate their own electrical sparks.

Why the Heart Beats Early First organ: The heart is the very first major organ to form and function in the growing embryo.

Survival need: The tiny embryo grows too fast for oxygen to pass through it naturally, so it needs a pump.

Pumping blood: The primitive heart tube starts moving blood, food, and oxygen to support the rest of the body.

How the Heart and Brain DevelopWeek 3 (Day 18-21): Small heart tubes fuse together in the chest area.

Week 4 (Day 21-22): Muscle cells contract on their own, and the first faint pulse or heartbeat begins. At this stage, the neural tube (which becomes the brain and spinal cord) is only just starting to close and take shape.

Weeks 6 to 10: The heart twists into its four-chamber shape.

Weeks 10 to 12: The brain finally matures enough to start sending signals to the heart to help control its rate.
