Describe the mechanism of glucose absorption in the small intestine.

What organ is physically responsible for creating force that acts to decrease the thoracic volume during expiration?

Tissues are selfish. Active tissues try to grab as much oxygen as possible.  Thus, they release substances that trigger relaxation of precapillary sphincters in order to increase blood flow through the tissue, and decrease affinity of Hb to Oxygen, so that Hb would release more Oxygen molecules. Name two substances released by active tissue that are simultaneously responsible for both mechanisms.
