What does this mean? Substances can diffuse is and out of it 1 of 12 What are networks of capillaries called Capillary Beds 2 of 12 When blood passes through these networks what happens? Small molecules are forced out to form the tissue fluid, which surrounds the cells 3 of 12 What do the waste chemicals do? They diffuse out of the cells into the tissue fluid, then into the capillaries 4 of 12 What does tissue fluid allow cells to do? It allows cells to get the substances they need and get rid of waste without a capillary supplying every cell 5 of 12 What is the job of the skeleton? Support the body, allow it to move, protect vital organs 6 of 12 What are the properties of ligaments? High tensile strength, slightly elastic. Allow stable joints but still allow movement 7 of 12 What does cartilage do? Reduces friction between bones and can be slightly compressed to be used as a cushion 8 of 12 What do membranes do at some joints? The release oily synovial fluid to lubricate the joints, allow them to move easily by reducing friction 9 of 12 How are muscles attached to bones? Tendons 10 of 12 How do muscles move joints? They contract 11 of 12 What are pairs of muscles called? Antagonistic 12 of 12
