Describe double circulation in human being why
is it necessary ?
Answers
Explanation:
It is necessary for a human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature.
Answer:
it is the passage of the same blood twice through the heart once on the right side and then on the left side in order to complete a cycle .
Double circulation has two components pulmonary and systemic .In pulmonary circulation, deoxygenated from all over the body pours into the right auricle, right ventricle, pulmonary Arch to be sent to the to lungs for oxygenation. oxygenated blood is taken by the pulmonary veins.
In this circulation ,oxygenated blood brought by pulmonary veins entres left auricle, left ventricle and then aorta to supply oxygen to all parts of the body
