What is closed circulatory system. Explain its advantages
Answers
Answer:
The closed circulatory system has moreadvantages over the open circulatory system.
1.The blood transfers faster in the closed system, thus oxygen, nutritients, and wastes transport fast also.
2. Specialized cells help carry nutrients.
Explanation:
Human beings, as well as animals, have blood flowing throughout their bodies. Now, how does the blood circulate, getting from the brain to the farthest part and back again? Well, this method in transporting blood within the body is known as the circulatory system, which consists of a complex highway of vessels with the primary purpose of moving blood that contains oxygen and other nutrients.
There are two types of circulatory system, namely the open circulatory system and the closed circulatory system, with the latter having more of particular interest to us knowing that it is the type that we, humans, have. Unlike the former, the latter is more controlled and structured, with the blood always flowing inside vessels that can be found throughout our entire body, making up its plumbing circuit that is also broken down into three different kinds of vessels—arteries, capillaries and veins—that transport blood throughout the body. The circulation works with the arteries being responsible for moving blood away from the heart and to the tissues. When blood reaches the tissues, it is contained inside the capillaries, which are the very tiny vessels that are found inside thin walls, which are responsible for allowing the waste and gas exchange to occur between the tissues and the blood. From here, the blood then leaves the capillaries and flows into the veins that are tubes that carry blood back to the heart.
While it is an essential system in the body, the closed circulatory system is often assessed against the open circulatory system in terms of efficiency in helping our body function. To get a good idea about this matter, let us take a look at its pros and cons.
