Who Else Wants To Learn About Introduction To The Human Body?

Man is probably the most complex organisms on this planet. Imagine billions of microscopic parts, each with its own identity, in conjunction with an organized fashion in favor of size. The human body is a single structure but consists of billions of smaller structures of four main types:

Cells

The cells have long been recognized as the simplest units of living matter that can sustain life and reproduce. The human body consists of numerous cells, begins as a single newly fertilized cell.

Tissues

For example, the stomach is an organization of the muscles, connective tissue, epithelial and neural tissues. Muscle and connective tissue in the shape of the wall, the epithelium and connective tissues form its lining, and nervous tissue extends throughout both the wall and the coating.

Systems

The systems are the most complex of the component units of the human body. A system is an organization of varying numbers and types of organs, so that together can perform complex functions for the body. Ten major systems compose the human body:

• Skeletal
• Muscular
• Nervous
• Endocrine
• Cardiovascular
• Lymphatic
• Respiratory
• Digestive
