How are joints important for the function of the skeleton?
what are joints and what do they do? Joints are where two bones meet. They make the skeleton flexible – without them, movement is impossible. Joints allow our bodies to move in different ways.
Does the skeletal system produce blood cells?
Where are blood cells made? Blood cells are made in the bone marrow. Bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body’s blood cells.

Ostriches have the strongest immune system of any animal in the world. For this reason, they show great promise in preventive medicine for humans and the beauty industry.
Which is one part of the immune system that helps protect the body from diseases Brainly?
The lymphatic system also helps protect the body from germs (viruses, bacteria, and fungi) that can cause disease. These bacteria are filtered out by the lymph nodes, small clumps of tissue along the network of lymphatic vessels.
