Anatomy of the Human Body
The Anatomy of the Human Body (pronunciation: /əˈnætəmi ɒv ðə ˈhjuːmən ˈbɒdi/) refers to the study and understanding of the physical structure and internal workings of the human body. The term 'anatomy' is derived from the Greek word 'anatome', meaning 'dissection'.
Overview
The human body is a complex biological system involving cells, tissues, organs, and systems all working together to make up a human being. From the nervous system to the respiratory system, each part of the body plays a crucial role in our overall health and functioning.
Cells
The smallest unit of life in the body is the cell. Cells group together to form tissues, which in turn combine to form organs.
Tissues
There are four basic types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Organs
Organs are structures composed of two or more different types of tissues, they have specific functions and usually have recognizable shapes. Examples include the heart, lungs, and liver.
Systems
The human body is made up of several organ systems that work together as one unit. These include the circulatory system, digestive system, endocrine system, muscular system, nervous system, reproductive system, respiratory system, skeletal system, and urinary system.
