Learn values of fruits to man!

Fruits

Scientifically, a fruit is a mature fertilized ovary. Fruits are formed after the fertilization of ovules. The ovules develop into seeds and the ovary into a fruit. The food we obtain from fruits is manufactured by photosynthesis in the leaves of a plant. Fruits are therefore storage organs of food.

Fruits are an important component of a healthy human diet. They naturally contain low calories, fat, sodium, and cholesterol. They keep the body healthy and have many benefits including the following:

Lowering the Risk of Illness and Disease: The many vitamins and nutrients in them reduce risk for many illnesses such as: Stroke, heart disease and other heart-related illnesses; type 2 diabetes; certain cancers, such as mouth, stomach, and colon-rectum cancer; kidney stones and Bone loss.

It is important to eat a variety of fruits, because different fruits contain different vitamins. Mangoes, papayas (pawpaw), melons and citrus fruits, like oranges and grapefruit, have high vitamin C concentration. Cantaloupe, apricots, peaches, and nectarines are sources of vitamin A.

Learn a lesson about why and how we breath!

The processes of breathing and gaseous exchange are very important in the maintenance of life. Health science emphasizes living in a clean atmosphere to have safe lives.Read on to learn how and why we breathe.

Lungs and breathing:

Cells need oxygen and they produce carbon dioxide as a waste product. The importance of breathing is to get oxygen into the body and remove the carbon dioxide.

Location of the Lungs:

The lungs are found in the thorax which is the part of your body protected by the rib cage. The lungs are two (the left and right) and are pink in color because of the dense capillary network around them. The trachea divides into two bronchi, one going to each lung.  The bronchi split progressively into smaller tubes called bronchioles. The bronchioles finally end at small bag called alveoli where the exchange of gases takes place. Just below the lungs is the diaphragm which separates the thorax from the abdomen.
