Whois & Analysis for knowyourbody.net

The human body is the entire structure of a human being.

It is composed of many different types of cells that together create tissues and subsequently organ systems.

They ensure homeostasis and the viability of the human body.

A biological system is a complex network of biologically relevant entities.

As biological organization spans several scales, examples of biological systems are populations of organisms, or on the organ- and tissue scale in mammals and other animals, the circulatory system, the respiratory system, the nervous system, etc.

In biology, an organ or viscus is a collection of tissues joined in a structural unit to serve a common function.

In anatomy, a viscus is an internal organ, and viscera is the plural form.

A bone is a rigid organ that constitutes part of the vertebrate skeleton.

Bones support and protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

Bones come in a variety of shapes and sizes and have a complex internal and external structure.

They are lightweight yet strong and hard, and serve multiple functions.

Muscle is a soft tissue found in most animals.

Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell.

Muscles function to produce force and motion.

They are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.
