Hemoglobin is the oxygen-carrying protein inside red blood cells. It gives red blood cells their red color. People with anemia do not have enough hemoglobin. The body needs certain vitamins, minerals, and nutrients to make enough red blood cells. Iron, vitamin B12, and folic acid are three of the most important ones.

More about the contents of cells generally, is available on the page about animal cells. The components of skeletal muscle cells that are specific to muscle tissue are myofibrils. 1  Each muscle fibre ( muscle cell ) is covered by a plasma membrane sheath which is called the sarcolemma.ore about the contents of cells generally, is available on the page about animal cells.
