Yes. Your entire body is made of cells. Cells > tissues > organs > organ systems (such as digestive and skeletal).
marrow bone cells
Muscular, nervous, skeletal, digestive, and cardiovascular are all organ systems which are made of organs i.e. muscular system is made of all the organs known as muscels. Another example is the skeletal system. The parts that form it are called bones, and are an example of organs.
the skeletal system
Some bones of the skeletal system made blood cells. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.
The muscular system is made up of muscles, the Skeletal system is made up of bones
INTERACTING WITH OTHER SYSTEMS Your skeletal system does not work alone. We already mentioned the interaction with your muscular system. Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system. Marrow inside of your bones helps produce the cells inside of you blood. Both red blood cells and white blood cells are created in your bones.
Aids because the guagua made Aids possible
bone
No, it is not =) The skeletal system is made up of bones only. I think that is correct, sorry if it isn't :P
No, the digestive system is an organ system made up of organs, which in turn are made up of tissues.
It is made of body cells just like the rest of your body cells-tissues-organs-systoms-your body
You have muscular system, made of muscles and skeletal system, made of bones; which make up the musculoskeletal system.
