What Are Bones Made Of?

If you've ever seen a real skeleton or fossil in a museum, you might think that all bones are dead. Although bones in museums are dry, hard, or crumbly, the bones in your body are different. The bones that make up your skeleton are all very much alive, growing and changing all the time like other parts of your body.

Inside the human digestive system

The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat as energy, our body has to break the food down into smaller molecules that it can process; it also has to excrete (or get rid of) waste.

Most of the digestive organs (like the stomach and intestines) are tube-like and contain the food as it makes its way through the body. The digestive system is essentially a long, twisting tube that runs from the mouth to the anus, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals. Without the digestive system, our bodies would not be able to get nutrients from the food we eat or get rid of the waste products that food makes and we would soon become ill!

Top 10 facts about the human brain and nervous system

The human brain is like a powerful computer that stores our memory and controls how we think and react. It has evolved over time and features some incredibly intricate parts that scientists still struggle to understand.

The brain is the centre of the human nervous system, controlling our thoughts, movements, memories and decisions.

Our nervous system is the message centre of our body. Messages of the nervous system travel throughout the body to help the body function and stay safe. The nervous system is an amazing and complex network of cells that relay messages from all parts of our body to our brain.

The spinal cord is the main highway in which these messages travel. Messages can travel in such a short span of time so that it is almost immediate.

Plant Cells vs. Animal Cells, With Diagrams

Cells have often been referred to as "the building blocks of life", which indeed they are. All forms of life, from simple bacteria to human beings, are made up of cells. What is remarkable is that, despite their apparent differences, plant and animal life are made up of cells that are actually the same in most respects.

The most important structures of plant and animal cells are shown in the diagrams below, which provide a clear illustration of how much these cells have in common. The significant differences between plant and animal cells are also shown. The diagrams are followed by more in-depth information.
