How does the Heart and Cardiovascular System Work?

Cardiovascular System The blood circulates around the body by the vains and the heart pumping. The main part of the cardiovascular system is the heart because thats the muscle that pumps the blood into the vains and the muscle that keeps the blood clean and pumped around the body. There are three main ways that the blood is pumped around the body. The first way is Coronary circulation. The other way is pulmonary circulation and the other one is systemic circulation. There are two main vains one is superior vena cava and the other one is inferior vena cava

Heart and Cardiovascular System!!

The Heart is a powerful muscle it is about the size of you fist when its clenched. The heart is made up of 4 different parts the atrium and the ventricle. The heart is made up of 2 main muscles. The heart pumps good and bad blood, good blood and nutrients. The bad blood goes to you lungs to get more oxygen in them. The bad blood is blue and the good blood is red. The heart never gets tired it pumps blood around your body all day long and also when you are sleeping. The heart gets faster when you are doing exercise and when you are nervous. The heart does lots of different jobs the blood comes in the atrium and then the ventricle will pump the blood back into your body. The heart is the main muscle in your body because if you don’t have a heart you will not get blood around your body and you will die. Your body will pump blood around your body all day it. ** || **Identify Purpose/Audience** Purpose is to explain how the cardiovascular system works Audience, people wanting to find out information about the cardiovascular system e.g student doing research
