Why are people not able to scuba dive to the deeper parts of the ocean?

There is too much water pressure. If you go down too deep, your lungs and internal organs would all burst.. who would want that?

So basically, a human would need more protection than what scuba gear would offer. (ex: a submarine would be so much more suitable)

The human body can't take all that pressure of the water. Imagine all that weight of the water on a human, It's currently impossible.

Hope this helps!

Circulatory system pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.
