Multiple Choice

It has the primary duty of supporting the body. Along with support it helps to protect our organs (rib cage), and provides attachment points for muscles and tendons used for movement

Multiple Choice

There are two types, red and yellow. The red marrow (medulla ossium rubra) is where the red and white blood cells are made. Yellow marrow (medulla ossium flava) is mainly made of fat cells. Red marrow is found mostly inside flat bones like the pelvis and ribs. It is also located at the ends of long bones like the humerus of the arm and femur of the leg. Yellow marrow is located inside the cavity of the middle part of the long bones
