All About Vampire Snacks
The heart is the center of the body, the seat of life, will and emotion. Weighing about 10 ounces, it is about the size of your fist and has four chambers: the right atrium, left atrium and the right and left ventricles.
The heart pumps at 60 to 100 beats per minute through miles of blood vessels, delivering oxygen and nutrients to your body. About 35 million beats per year, a lot of pumping for one lifetime. Tell your Valentine you love them “A million barrels worth and 2.5 billion heartbeats”.
Plasma is the pale liquid that makes up about 55% of your blood. The other blood components are suspended in plasma, and it allows them to travel through the blood vessels and around your body!
Plasma itself plays a critical role in carrying waste products to the kidneys, liver, and lungs where they can be removed from the body. Plasma also helps maintain normal blood pressure and helps regulate the body’s temperature.
White Blood Cell
White blood cells, or Leukocytes, are your body’s white knights. If an enemy germ invades you, they ride to the rescue and fight to the death.
There are several different kinds of leukocytes, and each has special skills to help protect you. Neutrophils race to the scene when bacteria attack. B cells neutralize viruses and T cells move in for the coup de grâce.
Red Blood Cell
Red blood cells, or erythrocytes, contain the hemoglobin that carries oxygen and carbon dioxide around the body. (Erythro means red in Greek, and cyte translates to cell.) Hemoglobin gives red blood cells their Characteristic color. When it is oxygen-rich, it appears reddish; when oxygen-poor, it is darker and bluish.
Although erythrocytes are flexible (which permits them to squeeze through capillaries), they typically have a distinctive biconcave shape that helps maximize surface area to facilitate the exchange of gases.
