This is not my homework questions, its for my review, if u're willing to help please do help me out.
The mammalian circulatory pattern has the advantage when compared to the fish circulatory pattern that :
the blood returns from the Right / Left side of the heart to be pumped a second time before traveling to the tissue.
please tell me if its RIGHT or LEFT coz i can't figure out by looking @ the diagram...
The right & left atria of the mammalian heart contract @ approximately the same time because:
1. special conducting fibers transmit the signal rapidly over the septum thatseparates the chambers.
2. a special node of tissue receives & delays the signal for the appropriate period of time.
3. the intercalated discs spread the signal rapidly between the individual muscle cells.
4. a pacemaker exists in the wall of the right atrium.
5. connective tissue separates the atria from the ventricles.

haha it's the right. just rmb. deoxygenated blood returns to the right side of the heart.

The right side of the heart:
-- receives the blood into the right atrium as the blood returns to the heart from the body
-- pumps the blood to the lungs from the right ventricle
The left side of the heart:
-- receives the oxygenated blood from the lungs into the left atrium
-- pumps the blood to the body from the left ventricle
Memory trick:
Blood is pumped RIGHT TO the lungs.
Then all that's LEFT is the rest of the body.

basically the circulatory system exchanges gases and lungs at the site of the aveoli in the lungs. The lungs exchange good oxygen from the atmosphere into the bloodstream at this site. This good oxygen circulates in the blood and nourishes the tissue throughout the body. Again at the exchange site of the aveoli lungs the oxygen is exchanged for the waste (like carbon dioxide) and carried out of the body by exhalation.

It goes right side ---> lungs ---> left side---> body
The best answer is 3.
