In addition to air and
water, our body constantly needs regular inflow of food, which provides the
energy reserves necessary for movement, breathing, thermoregulation, heart,
blood circulation and brain activity. In the process of digestion of food
decays to individual glucose molecules which then fall through the intestinal
wall into the bloodstream. With blood flow glucose transported to the liver,
where it is filtered and delayed in reserve. The pituitary gland supplies the
pancreas and thyroid glands signal to the release of hormones that cause the
liver to throw out the accumulated glucose in the bloodstream, and then
delivers it to the blood to the organs and muscles that are in need of it. Having achieved the
desired body glucose molecules penetrate into the cells, where it is converted
into a source of energy that is available for use by cells. Thus, the process
of continuous energy supply agencies depends on the level of glucose in the
blood.
Haploid; reproductive
After the halving of chromosomes, the cell becomes a haploid and this is done for gametes, or reproductive cells.
