What are Organs?

What is Organ Systems?
There are 11 organ systems in the human body: the digestive system, the endocrine system, the integumentary system, the lymphatic system, the muscular system, the nervous system, the reproductive system, the respiratory system, the skeletal system, the urinary system, and the vascular system.
Important Facts about Human Body
1. The human body composed of trillions of cells that work together to keep us alive.
2. Our cells are constantly regenerating, so the cells that make up our body today are not the same cells that made up our body a year ago.
3. The cells in our body are organized into tissues and organs, which work together to carry out the body’s functions.
4. Our body is constantly fighting off disease and infection, and our immune system is responsible for protecting us from harm.
5. Our body has many different systems that work together to maintain homeostasis, or equilibrium.
