HUMAN HEART

Heart:
The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.
The heart has four chambers:
The right atrium receives blood from the veins and pumps it to the right ventricle.
The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.
The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.
The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. A web of nerve tissue also runs through the heart, conducting the complex signals that govern contraction and relaxation. Surrounding the heart is a sac called the pericardium.

RADISH

Radish
The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family that was domesticated in Europe, in pre-Roman times. They are grown and consumed throughout the world. Radishes have numerous varieties, varying in size, color and duration of required cultivation time. There are some radishes that are grown for their seeds; oilseed radishes are grown, as the name implies, for oil production. Radish can sprout from seed to small plant in as little as 3 days.

History
The descriptive Greek name of the genus Raphanus means "quickly appearing" and refers to the rapid germination of these plants. Raphanistrum, from the same Greek root, is an old name once used for this genus. The common name "radish" is derived from Latin radix (root). The radish has been used over many centuries.
Although the radish was a well-established crop in Hellenistic and Roman times, which leads to the assumption that it was brought into cultivation at an earlier time, Zohary and Hopf note that "there are almost no archeological records available" to help determine its earlier history and domestication. Wild forms of the radish and its relatives, the mustards and turnip, can be found over west Asia and Europe, suggesting that their domestication took place somewhere in that area. However Zohary and Hopf conclude, "Suggestions as to the origins of these plants are necessarily based on linguistic considerations.
Nutritional Benefits of Radishes
Radishes, which are good sources of various nutrients, vitamins and minerals, come in a variety of types, including red globe, daikon and black radish. While the red globe variety is a source of the nutrients potassium, molybdenum and folic acid, all radish types and their leaves can be good sources of vitamin C. The nutritional content of 3.5 oz. of raw radish root contains 233mg of potassium, 25mg of calcium, 14.8mg of vitamin C and many other nutrients, according to Elements4Health.com.
