Locomotion system consists of bones and muscles. Bones link together and make skeleton. Skeleton supports the body and gives the shape.
Слайды и текст этой презентации
Слайд 3Muscles connect to bones. Muscles contract and move bones and
the whole body.
There is a structure called red bone marrow
inside the bone. It produces blood cells. Another function of locomotion system is storage of calcium (Ca) and phosphorous(P). They make bones strong. Also bones consist of organic molecules, like proteins. They makes bone more elastic.
Слайд 4Structure of human skeleton
Knowing the skeleton structure makes you really
best biology student!
Слайд 5Rethink your drink
Many of fizzy drinks contain phosphoric acid which
decreases the absorption of calcium in the body. Deficiency of
calcium make bone weak so it breaks easily. So rethink your choice the next time you reach for a dizzy drink.
Слайд 6Archaeologist is scientist who study human history digging up their
remains. Using skeleton bones he knows date of life, gender,
culture and age.
