1.	* What is double circulation & why isit necessary
Answer» ONG>Answer: Hi good MORNING here is your answer :- Mammals have a double circulatory system. This means that during a single cycle, the blood goes TWICE in the heart. There are TWO loops in which blood is circulated. One loop is OXYGENATED and the other is de-oxygenated. This double circulatory system is necessary because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles. Explanation: MARK IT BRAINLIEST
