El Sistema Circulatorio: Cómo Funciona

Study Notes

The circulatory system is one of the most important systems in our bodies because it helps deliver oxygen from your lungs to all parts of your body. Here's how this vital network works:

At the heart of your circulatory system lies your heart (the pump), which pumps blood through arteries (pipes) to capillaries that branch off into smaller tubes called veins. Blood flows through these vessels under pressure created by the beating of your heart.

The job of the circulatory system is to bring oxygen from the air you breathe into every cell in your body, where it combines with other chemicals to create energy. At the same time, it takes away waste products made when cells work, so they can go out of the body in sweat or urine. Every organ needs its own blood vessel supply, just like every house has electricity going to different rooms.

There are two main types of blood vessels: Arteries carry blood away from the heart; Veins return it back to the heart after the blood has been used up in your body. In addition, there are also small branches between them called capillaries, which release water from the blood directly onto tissues inside organs such as muscles, kidneys, and liver. This process allows nutrients and oxygen to seep into healthy tissue while wastes get absorbed back into your bloodstream.

One important part of keeping the whole system working properly is getting enough exercise: When you move around, more oxygen gets to the muscles and brain, helping them do their jobs better. If you don't exercise much, though, carbon dioxide buildup leads to poor circulation—making it harder for your body to function effectively without becoming sluggish. That's why regular physical activity is crucial for good health!
