1.	What is the advantage of having 4chambered heart ???
Answer» Answer:The advantages of having four chambered heart is that:Explanation:* the four chambered heart\'s left half is separated from right half which prevent mixing of oxygenated and deoxygenated blood*it allows the efficient supply of oxygenated blood to all parts of the body . this is useful in animals which have high energy needs such as mammals ,birds ,etc The four chambered heart is present in warm blooded animals as they cannot tolerate the mixing of oxygenated and deoxygenated blood so to prevent it from mixing four chambered heart is present The\xa0four-chambered heart\xa0has a distinct\xa0advantage\xa0over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without\xa0having\xa0to mix the two. That system is very efficient.\xa0In\xa0four chambered heart, left half is completely separated from right half by septa. It serves following two purposes (a) ensures complete segregation of oxygenated and deoxygenated blood (i.e., no mixing). (b) allows a highly efficient supply of oxygenated blood to all parts of the body.a
