The red blood cells are manufacture in the bond marrow and the longest that a red blood cell can live is 120 days.
5. MUSCLE CELLS: Are elongated cells that have the ability to contract.
Muscle cells are made up of myosin and actin, which are protein filaments that slide past one another in order to produce contractions, which changes the length and shape of the cell. Muscles cells are largely responsible for maintaining and changing posture, locomotion and movement of internal organs. There are three basic types of muscles, they are skeletal, cardiac and smooth muscles.
