There's another strong line of evidence that dinosaurs weren't strictly monochromatic: the brilliantly colored plumage of modern birds. Birds--especially birds that live in tropical environments--are some of the most colorful animals on earth, sporting vibrant reds, yellows and greens in a riot of patterns.he earliest dinosaur models displayed to the public, at England's Crystal Palace exposition in 1854, depicted Iguanodon, Megalosaurus and Hylaeosaurus as looking very much like contemporary reptiles, complete with splayed legs and greenish, pebbly skin.
Blood Pressure Graph By taking your pulse, you can feel that blood pressure fluctuation with each heartbeat. The pulse which you feel is actually a pressure wave that travels from your heart though your arteries Systolic Pressure Systolic pressure is the maximum pressure exerted by the blood against the artery walls. It results when the ventricles contract.
Blood pressure (BP) is the force or pressure that blood puts on the walls of your arteries as it goes through your body. BP readings are usually written as 2 numbers. The first or top number is called systolic BP. The second or bottom number is called diastolic BP. Normal BP is less than 120/80.
