New sections(s) - homeostasis, types of blood, types of arteries, etc.[edit]

Seems to me that while this article does a good job of defining the different types of circulatory systems, it does very little to go in-depth with them. The section on its discovery is longer than them, for Heaven's sake. So, I propose a new section dealing with the specificities of each type of circulatory system.

Please change the animated GIF of the circulation of a red blood cell and the caption, "An animation of a typical human red blood cell cycle in the circulatory system. This animation occurs at real time (20 seconds of cycle) and shows the red blood cell deform as it enters capillaries, as well as changing color as it alternates in states of oxygenation along the circulatory system."

The assertion that human red blood cells take on average 20 seconds to complete one cycle of circulation is incorrect. The average human blood volume is about 5L and the average cardiac output is about 5L/min, so the average circuit time for a red blood cell is 1 minute. Actually, because the circuit down to the foot (shown in the GIF) is one of the longest pathways a RBC can take, the time is probably much longer than 1 minute, since 1 minute is just an average time.

The references I cited are as follows: The first reference states that the average circulation time for blood is about 1 minute. The second reference states that the average blood volume in an adult is 4 to 6 L, and the third reference states that the average cardiac output in an adult at rest is 5L/min. — Preceding unsigned comment added by User96384 (talkcontribs)
