Use the experiments, activities and games to help you learn about the nervous system. Your Body's Systems The circulatory system is the body's transport system. It is made up of a group of organs that transport blood throughout the body. The heart pumps the blood and the arteries and veins transport it. Oxygen-rich blood leaves the left side of the heart and enters the biggest artery, called the aorta. The aorta branches into smaller arteries, which then branch into even smaller vessels that travel all over the body. When blood enters the smallest blood vessels, which are called capillaries, and are found in body tissue, it gives nutrients and oxygen to the cells and takes in carbon dioxide, water, and waste.

How Your Body is Like a Factory Did you know that you can actually hear pulmonary circulation? Pulmonary circulation is the movement of blood though the right side of the heart, to the lungs, and then back through the left side of the heart. The “lub dub” you hear when using a stethoscope is the sound of the ventricles contracting and the heart valves closing during this circulation process. Blood takes a very precise route during pulmonary circulation. Two large veins called the vena cavae bring blood to the right atrium of the heart. The atrium fills with the waste-rich blood and then contracts, pushing the blood through a one-way valve down into the right ventricle.

Animal Systems A system is a group of organs that work together and provide an organism with an advantage for survival. It is the most complex organization in your body and the final level of the progression from cells to tissues to organs and then systems. Systems work alone and with other systems to allow your body to maintain homeostasis. Homeostasis is a stable internal environment that allows you (and your cells) to survive. While every one of your systems is needed to survive, your nervous system is the most important as you continue reading this page. Integumentary System Introduction The integumentary system consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. In order to do these things, the integumentary system works with all the other systems of your body, each of which has a role to play in maintaining the internal conditions that a human body needs to function properly.
