Additional return flow may be generated by the movement of skeletal muscleswhich can compress veins and push blood through the valves in veins toward the right atrium. In some simple animals, including small worms and molluskstransported oxygen is merely dissolved in the plasma.
If it's negative, you don't. It is thought that tunicates sea squirts might use vanabins proteins containing vanadium for respiratory pigment bright-green, blue, or orange. This rhythm, or heart rate, is our pulse. They develop into macrophages after they have left the blood and migrated into tissue.
Hemerythrin is violet-pink when oxygenated.

Basophils White blood cells: Help heal wounds. The absence of these cell structures leaves room for the hundreds of millions of hemoglobin molecules found in red blood cells.
Instead, it combines with the N-terminal groups on the four globin chains. Red blood cells contain a protein know as hemoglobin which makes our blood red. The vast area of capillary membrane, through which water passes freely, would permit instantaneous loss of the plasma from the circulation were it not for the plasma proteins—in particular, serum albumin.
Healthy erythrocytes have a plasma life of about days before they are degraded by the spleenand the Kupffer cells in the liver.
