blood could not circulate through the body unless it passed through the heart.
The heart connects to the arteries and veins, to pass the blood through the body.
you will die because that system helps blood pass through your body and that system has your heart in it.
In order for blood to change its direction or pathway in the body, it must pass through the heart. The heart receives blood from the body, pumps it to the lungs to pick up oxygen, and then pumps it back out to the rest of the body.
Human circulatory system is a double circulatory system (two times) because blood passes through the heart twice in a complete circuit. (for oxygenated blood and deoxygenated blood) There are two types of circulatory system in human beings : 1.pulmonary circulatory- blood circulates from the heart to the lungs and back to the heart 2.systematic circulation- blood circulatea from the heart to other organs and back to the heart. The human heart will undergo over 3 billion contraction cycles
the blood passes through your heart
All the blood flowing through the intestines passes through the liver on its way back to the heart.
2 times
With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava. The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.
because the blood gets depleted of its oxygen content once it reaches the heart and it needs to be oxygenated when it goes to the different parts of the body. as you may notice, the heart is divided into four chambers. the right side deals with the unoxygenated blood while the left side deals with the oxygenated blood. since the heart has no capacity to supply oxygen depleted blood with oxygen, it has to pass first to the lungs before it is pumped to the different parts of the body.

Oxygenated blood travels from the lungs through the pulmonary veins into the left side of heart, which pumps blood into the body. Good luck hope this helps ;)
