Another biological breakthrough has gone a step further. A team of scientists from University of Pennsylvania and the University of Texas Southwestern Medical Center have frozen, thawed and coaxed back to life, not just a sperm but the spermatogonial stem cell or the whole sperm factory. Freezing the sperm will only be good while the sperm will last, which is not long. However a sperm factory can theoretically go on forever. This is streamlining the human race!

The food materials, which have been absorbed into the bloodstream, travel to the cells. The cells burn some foods, to supply the body with heat and energy. They build and repair tissues with others. If an inactive person overeats, the cells are provided with too much food; so the excess is stored, and he becomes overweight.

It usually takes 5 or 6 hours for an ordinary meal to move on out of the stomach. (A very large meal will take longer, because it is difficult for the stomach to digest it.) For this reason, nutritionists will tell you not to eat more than three meals a day; and, if you digest food well, only two. If you are overweight, try it.

Digestion continues in the stomach, where the gastric juices mix with the food; the mass is churned and moved about by the contraction (peristalsis) of the muscular stomach walls. When the bottom part of the food is digested well enough, the pyloric valve relaxes, and food begins traveling into the small intestine.

This system starts when food enters your body and ends when the waste leaves it. The process is called digestion and it takes place in the digestive tube, also called the alimentary canal, the gastro-intestinal system, or the G.I. tract.

The heartbeat originates in the S.A node, and immediately the entire auricle contracts. Then the A.V node picks up the message and relays the signal to the muscle fibers of the ventricle, which contracts. Heart block is a condition which occurs when disease of the bundle of His interrupts communication between the auricle and the ventricles.

All bloods fall into one of 4 groups: AB, A, B, and O. Blood from a person in your group would match yours safely. Type O can be given to any other blood group and is called the universal donor. Type AB can receive blood of any other group and is called the universal recipient.

Carbon dioxide is removed through the respiratory system, but there are other wastes which result when body cells burn food. Many of these wastes are in the circulating blood. Some of them are removed in the blood filtration and removal plant, which is the urinary system.
