1 Answer

Answer :

(4) Its blood carries wastes for the first time Explanation: The Fetal circulatory system is unique during pregnancy before the lungs first come into use at birth. Its circulatory system must reorient itself to send all the blood through the lungs to receive oxygen. The baby is cut off from the placenta, which was previously its only source of nourishment. The blood vessels that ran through the umbilical cord constrict and close. All this happens in a few moments when the baby is born.

The closed circulatory system is more efficient. Since blood circulates only inside blood vessels it can do it with more pressure reaching farther distances between the organs where hematosis happens and the peripheral tissues. In addition the circulatory speed also heightens making possible more oxygen supply to great consuming tissues, like the muscle tissues that then can perform faster movements. Animals with an open circulatory system (with the exception of insects that do gas exchange independently from the circulation) are generally slower and have a low metabolic rate.
