5 Did You Know Facts
When you breath in oxygen, the circulatory
system carries the oxygen, through veins,
to other cells of your body. Then, after the
oxygen has been processed by the cell it
was brought to, the circulatory system carries
the dissolved carbon dioxide back to the lungs,
where it is then breathed out. Without the
circulatory system, there would be no way
to circulate nutrition to other cells in the body.
One of the main organs in the
circulatory system is the heart. The
human heart is double sided,
and has four chambers, where
blood is constantly being
pumped. The heart fills with
blood, then pumps the blood
through veins in the body. The
veins also bring blood back to the
heart where this process is
done over and over again.
The vessels are also a major organ in the circulatory system. The vessels are the passage-way connected to the heart and all other parts of the body. So the heart pumps blood, the blood travels through the vessels (which run through your entire body,) and bring nutrients and oxygen to other cells, as well as bringing waste products back to the heart and lungs where they are released from the body.
The heart is a muscle that pumps blood. The heart fills with blood before each beat. To squirt the blood along, the heart contracts. The blood is then carried through the arteries. The blood is then delivered by the blood vessels to different cells in the body. The blood that has given the oxygen and nutrients to the cells then is brought back to the heart through the veins.
Blood leaving the heart to be delivered to different cells in the body.
The circulatory system is connected to every system in the body, including the digestive system. The circulatory system is responsible for taking the nutrients that have been absorbed from the digestive system, and bringing them to other parts of the body.
The circulatory system is also connected to the respiratory system. The red blood cells travel to the lungs, where they collect as much oxygen as possible, and bring the oxygen to other tissues and cells through the body.
Red Blood Cell
The heart pumps the blood by contracting.
Myocardium are the cells that create the cardiac muscle tissue. The cells send messages to one another through intercalated disks that helps the heart contract.
Cardiac tissue forms the contractile wall of the heart.
When people don’t have enough red blood cells they develop a condition called Anemia. Red blood cells deliver oxygen when you are lacking in them you begin to feel tired and have a low energy. By eating iron regularly you should have a less chance of being anemic. If you are anemic all the time people will be treated with iron supplements.
Hypertension is another disease that affects the circulatory system. Hypertension is another word for high blood pressure. Having high blood pressure causes the heart to work harder then it should to pump blood through our body and can cause hardening of the arteries. This can lead to heart attacks and strokes. Some risk factors include: smoking, obesity, age,inactivity and stress.
Most children are born with a healthy circulatory system. To maintain a healthy circulatory system is to exercise. The major organ of the circulatory system is the heart which is a muscle, if you do not exercise your muscles your muscles will not strengthen. Avoiding unhealthy foods that are high in fat is a big factor to maintaining a healthy circulatory system.
Smoking can also damage the heart and blood vessels because a waxy substance called plaque starts to build up in your arteries. The plaque will then start to narrow the path for the flow of the blood limiting the supply of oxygen and nutrients.
A cardiologist is a specialist who helps identify, treat and prevent heart disease.
