The Human Body is a complex biological system that make up a human being. Working together, these systems allow for life, movement, growth, repair, cognitive function and much more. 

 

They hold us up and help us move our bodies. This video explores our bones and muscles! We look at the different kinds of bones: long bones, flat bones and irregular bones. We also learn terms like smooth muscle, saddle joint and periosteum. Finally, we’ll talk about how to keep our bones and muscles healthy.

The cardiovascular - or circulatory - system is our body’s transportation system. It consists of a pump, the heart, and an enormous network of pathways, the blood vessels. But how does blood circulate through our bodies? And what other parts of the body are involved in the cardiovascular system? Every day, your heart beats more than one hundred thousand times. In this film, we’re going to explore the cardiovascular system.

When we breathe, our bodies exchange gases with the environment in a process called breathing - or respiration. But why do we have to breathe? What organs do we use when we breathe? In this video, we explore breathing and our lungs. We also learn terms like alveoli, bronchi and diaphragm. Finally, we’ll talk about how to keep our respiratory system healthy.

 

Whenever you catch a cold, cut a finger or skin a knee, your immune system gets to work. But how does this system actually work? And what organs are involved? This video will teach us about the human immune system and how it keeps us healthy. We’ll be going through concepts like transmission, allergies, and blood cells. We’ll also be taking a look at the difference between the immune system as a whole and our body’s defenses. To wrap things up, we’ll describe a few immune system disorders and also provide a few pointers to promote a healthy immune system.  

 

The skin is the largest organ of the body. It protects us in many different ways. In this video, we will get to know all about skin. We’ll explore its structure, how it functions, and how it helps us regulate body temperature. Oh, and why do we get goosebumps and why sweat can be so smelly.  

 

One of the most important features of the body is that it eliminates things it doesn’t need, can’t use or that can harm the body. The body has its own filter systems for this, consisting mainly of the kidneys and liver. In this film, we learn about the important work they do. We go through terms like renal capsule, nephron and dialysis.   

 

The brain decides almost everything that happens in your body. It receives messages from the outside world and it also gets signals from the body’s internal organs.  In this film, we learn about the cerebrum, the diencephalon, the cerebellum, and the brainstem and what they do as well as look at how nerves and nerve cells look and examine the central and peripheral nervous systems.

The digestive system allows our body to break down what we eat in order to absorb and use the nutrients we need to thrive. We follow the winding road our food takes from the mouth to the rectum, and explore concepts like the esophagus, sphincter muscles, and chemical breakdown.
