In that research, eating just an ounce of nuts daily was linked to a 20 percent lower risk of death over a 30-year period. Nuts and General Health   Nuts have been a regular component of the human diet for thousands of years. A growing body of evidence that nuts are healthy prompted the U.S. Food and Drug Administration (FDA) in 2003 to issue a qualified health claim saying that current scientific data suggest that eating 1.5 oz (42g) of nuts each day may reduce the risk of heart disease. More recent research has shown that eating nuts is linked to a lower risk of colon cancer, gallbladder disease, and diverticu...

Two major functions of the blood include transporting substances to and from our cells and providing immunity and protection against infectious agents such as bacteria and viruses. Blood is a component of the cardiovascular system. It is circulated through the body via the heart  and  blood  vessels. Blood Components Blood consists of several elements. The major components of blood include plasma, red blood cells, white blood cells, and platelets.   Plasma: This major constituent of blood comprises about 55 percent of blood volume.

Cardiovascular System The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. This system is comprised of the heart and the circulatory system. Structures of the cardiovascular system include the heart, blood vessels, and blood. The lymphatic system is also closely associated with the cardiovascular system. Structures of the Cardiovascular System Heart The heart is the organ that supplies blood and oxygen to all parts of the body. This amazing muscle produces electrical impulses through a process called cardiac conduction. These impulses cause the heart to contract and then relax, producing what is known as a heart beat. The beating of the heart drives the cardiac cycle which pumps blood to cells and tissues of the body.  Blood Vessels Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body. Blood travels f...
