Younger primary students may have little knowledge about internal bodily organs. They tend to think the contents of the body are what they have seen being put into or coming out of it, such as food and blood. Their experiences with everyday cuts, scratches and bruises seem to reinforce a view that blood is below the surface of the skin, filling the spaces inside the body like a bag of blood.

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function.

What are the organs of the human body?

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts, listed in alphabetical order:. Within cells, the cytoplasm is made up of a jelly-like fluid called the cytosol and other structures that surround the nucleus.

The cytoskeleton has several critical functions, including determining cell shape, participating in cell division, and allowing cells to move. It also provides a track-like system that directs the movement of organelles and other substances within cells. This organelle helps process molecules created by the cell. The endoplasmic reticulum also transports these molecules to their specific destinations either inside or outside the cell.

The Golgi apparatus packages molecules processed by the endoplasmic reticulum to be transported out of the cell. These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components.

Mitochondria are complex organelles that convert energy from food into a form that the cell can use. They have their own genetic material, separate from the DNA in the nucleus, and can make copies of themselves.

The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA and separates the nucleus from the rest of the cell. The plasma membrane is the outer lining of the cell. It separates the cell from its environment and allows materials to enter and leave the cell. These organelles can float freely in the cytoplasm or be connected to the endoplasmic reticulum see above.

Human Body Worksheets

A number of complex processes and systems together form the human body. Zillions of cells and many organs work in coordination in the body to enable us to perform everyday functions. The human body and its anatomy can be complicated topics to study and revise. Therefore, we have come up with this list containing all the facts related to the human body. This list will help you memorize all the important body parts and their functions, for your exam.


You can also begin to see the interconnections between the different parts of the body in order to understand how the body functions. We should warn you that.

The Organization and Structure of the Human Body

You have probably heard this Billy Ray Cyrus song. Heartache, heartbreak Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart. The fact that the heart may start racing when one is excited or otherwise emotionally aroused may have contributed to this idea as well. In fact, the heart is not the organ that controls thoughts or emotions.

Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Read more.
