An "internal reservoir" of oxygen in rested muscle is found in oxygen molecules bound to
myoglobin
Circulatory systems compensate for
the slow rate at which diffusion occurs over large distances.
The fluid that moves around in the circulatory system of a typical arthropod is
the interstitial fluid.
Small swollen areas in the neck, groin, and axillary region are associated with
increased activity of the immune system.
What will be the long-term effect of blocking the lymphatic vessels associated with a capillary bed?
the accumulation of more fluid in the interstitial areas
Air-breathing insects carry out gas exchange
across the finest branches of the trachea and cell membranes
Most of the carbon dioxide produced by humans is
converted to bicarbonate ions by an enzyme in red blood cells.
Gas exchange in the aquatic salamander known as the axolotl is correctly described as
simple diffusion of oxygen into the salamander from the water.
Cyanide poisons mitochondria by blocking the final step in the electron transport chain. Human red blood cells placed in an isotonic solution containing cyanide are likely to
