A body can be looked at a lot like a highway. A highway is a system within a system, just like your body has systems within systems. The body has eleven different systems.
One of these systems, like a highway, acts like a transportation system.
The cardiovascular, or circulatory system, has three different parts that work together to make the body work right.
The cardiovascular system has a large heart muscle, blood and a bunch of different tubes, that make up the cardiovascular system.
These tubes are called blood vessels and the blood vessels help to circulate blood throughout the body, taking oxygen and nutrients to the different cells that are located throughout the body.
The cardiovascular system has three main functions in the body.
The first function is that it helps to make the heart pump blood, then, the blood circulates around the body with the help of the blood vessels, delivering oxygen and nutrients and removing different waste from the heart such as water, carbon dioxide, and even salt can be carried away.
The blood also helps fight different diseases in the body because it holds different special cells that help to fight the diseases.
Red cells ride through the “highway” of the blood vessels, the cardiovascular system, taking blood through all parts of your body.
The cardiovascular system is made up of blood vessels and the heart, and the blood vessels are like tiny tunnels that run all through the body.
The blood vessels are made up of arteries, which take oxygen to different parts of your body and veins that takes carbon dioxide from your heart to your lungs.
The heart is the most important muscle in your body.
The heart is an involuntary muscle, which means that it moves by itself. It is constantly moving, even though you do not feel it, and it moves when you are moving or even when you are sleeping.
When your heart moves, it is called a heartbeat and the heart beats at over 100,000 times in one day.
When the heart beats, it pulls blood in and then pushes blood out of the heart, and this helps the blood move fast enough to go throughout the whole entire body and back to the heart.
With this movement, the red blood cells move through the body to carry nutrients and oxygen.
The heart has different sides or chambers. The right side is called the right atrium and then it opens into the tricuspid valve, the lower right area is called the right ventricle, and then the pulmonary valve.
The heart beat makes the heart pump the blood through these different areas of the heart and then it goes into the arteries which leads to other parts of the body.
The red blood cells travel from the heart to the lungs to gather oxygen to take to another part of the body.
All bodies need oxygen and the lungs help by bringing the oxygen into the body and the blood vessels help take it to where it is needed.
The other side of the heart is where the blood cells carry the oxygen to.
This part of the heart has the left atrium, the mitral valve, the left ventricle and the aortic valve.
The red blood cells gather carbon dioxide at this time and carries this back to the lungs.
The heart has different valves that are similar to trap doors that allow the red blood cells to move in the direction that they are going and stops the cells from moving the wrong way.
All of these parts of the body work together in order to make the heart beat and to help blood pump all through the body.
