The message about the Russian flag: Red symbolizes energy, strength, courage, love and blood shed for the Fatherland. Blue is the color of faith and loyalty, consistency and honesty. White means peace, excellence, nobility and openness. There is a version that the red-blue-white tricolor was the first commercial maritime flag of Russia. Interesting fact: The national flag in Russia appeared at the turn of the 17th-18th centuries, during the era of the formation of Russia as a powerful state. For the first time the white-blue-red flag was raised on the first Russian warship "Eagle", during the reign of the father of Peter I, Alexei Mikhailovich. The Russian flag was adopted "August 22, 1991 year"

Классификация костей
Кость, хотя и прочная, является постоянно меняющейся тканью, которая имеет несколько функций. Кости служат для тела жёсткими конструкциями и, как щиты, защищают нежные внутренние органы. Они обеспечивают место расположения костного мозга, в котором образуются клетки крови. Кости также содержат запас кальция в организме. У детей некоторые кости имеют участки, называемые зонами роста. Кости удлиняются в этих местах, пока ребенок не достигнет полного роста, на тот момент зоны роста закроются. С этого момента кости растут в толщину, а не в длину, исходя из потребности организма в дополнительной прочности костей в определенных местах.
Хотя различные кости скелетной системы сильно различаются по размеру и форме, они похожи по структуре, развитию и функциям.
