Blood is pumped out of the heart to two places.. The blood that has used up it’s oxygen (and is de-oxygenated) goes to the lungs to get some more (this is then oxygenated blood) and then this blood goes back to the heart which then pumps it around the body, after it goes around the body it goes back to the heart to get sent back to the lungs. Oxygenated blood and de-oxygenated blood don’t get mixed up this way as the cells as the cells in your body need oxygen to survive so you don’t want to send them de-oxygenated blood by mistake!
The heart is actually two pumps in one, it’s quite neat. When it squeezes it pumps blood out in two directions from each pump (towards the whole body, or towards the lungs). And when it relaxes, it sucks in blood from two directions (from the lungs, and from the rest of the body).
The heart is not working alone…. it is doing so with you breathing: by breathing we take some air, containing oxygen, which is essential to us for moving, thinking, eating and have energy.
The oxygen is then taken by the heart, mixed with the blood cells and pushed to all the organs and the rest of the body.
The blood follows a cycle: after going through the body, it goes back to the heart to get more oxygen.
The system is called circulatory system. Heart permits blood to circulate and transport nutrients, oxygen, carbon di oxide, hormones and blood cells to and from the cells in our body. This transportation provides nourishment and helps in fighting diseases, stabilize temperature. Blood is circulated trough Arteries and Veins.
Great Question:)
You probably guessed that the blood just doesn’t slosh around your body once it leaves the heart.
It moves through many tubes called arteries and veins, which together are called blood vessels. These blood vessels are attached to the heart.
The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins.
The movement of the blood through the heart and around the body is called circulation, and your heart is really good at it — it takes less than 60 seconds to pump blood to every cell in your body- that’s amazing isn’t it 🙂
