The human body is magnificent. It is a single structure but it is made up of billions of smaller structures either cells, tissues, organs, or systems. It works wonders all day long and even when we are asleep without us noticing or worrying about any physiological process or function.
Our stomach digests the food, our lungs exchange gases, our heart pumps blood, and the maestro, the brain, controls all these functions and regulates them.
There are ten major systems in any human body and they are:
- The skeletal system
- The muscular system.
- The nervous system.
- The endocrine system.
- The cardiovascular system.
- The lymphatic system.
- The respiratory system.
- The digestive system.
- The urinary system.
- The reproductive system.
Each system represents an organization of varying numbers and kinds of organs. Those organs are arranged in a particular way so that together they can perform complex physiological functions of the body.
