The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion.

Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Biology - Transportation in Humans Introduction The blood is responsible to transport food, oxygen, and waste materials in human bodies. Blood usually consists of a fluid medium known as plasma where the cells remain suspended. Plasma is responsible to transport food, carbon dioxide, and nitrogenous wastes in dissolved form. However, oxygen is carried by the red blood cells. Many other substances such as salts, are also transported by the blood. A Human Heart The heart is one of the most significant muscular organs of a human body. As both the oxygen and the carbon dioxide get transported by the blood; so, to avoid the oxygen-rich blood from mixing with the blood containing carbon dioxide, the heart has different chambers. Oxygen-rich blood from the lungs comes to the thin-walled upper chamber of the heart on the left, i.e. the left atrium (see the image given above). When it is collecting the blood, the left atrium relaxes; however, while the next chamber, i.e. the left ven...
