The circulatory system brings the body's cells what they need to survive - oxygen and nutrients.
The center of the circulatory, or cardiovascular system, is the heart, a powerful pump organ designed to beat many millions of times over the lifetime of an organism. The heart circulates blood throughout the veins and arteries. Arteries carry oxygen-rich blood away from the heart, providing it to tissues, then returning the depleted red bloods cells back to the heart through the veins for reoxygenation.
We need the circulatory system because without that we would have no blood in our body... we would not get the nutrients we need and we would not be living without the heart.
Both are close circulatory system.
mammals have closed circulatory system and further double circulatory system.
circulatory system
Their circulartion system is very similar to humans (closed circulatory system)
Humans have a closed circulatory system, in which blood is pumped by the heart through dedicated vessels, where it stays contained, as opposed to an open circulatory system (usually found in invertebrates) where blood is pumped out of the heart and vessels.
YES.
Always! you need the process of the circulatory system in order to breathe and exhale waste.
you would need a cardiology doctor if the circulatory system fails
The circulatory system is important to humans because the main components are the heart, the blood, and blood vessels.
each and every moment.
yes areteries and veins
Humans have the most advanced blood and fluid circulatory system.
