All systems are in a cooperation for continuing the life and when one system is problematic, problems occur in other systems also. Some systems are main and their problems are directly affect human and there are also some systems like Endocrine system and their problems are effecting body in a time period. How many systems are there in a human?
There are 14 systems in a human body. They are various from Circulatory system to Excretory System, Skeletal system to Integumentary system.
One of the most important systems in human body is Circulatory system. Circulatory system is using for pumping the blood to all body.

Uh, who wrote this? A 4th grader who got a D in science? The excretory system? Excretion is part of the digestive system. And no real doctor counts “the Endocannabinoid system as a separate system. It’s part of the nervous system, at best.
