1. Exercise develops physical fitness.
2. Range of motion is how far any body part can move in any direction.
3. Muscle myofibrils are made of both thick and thin filaments. These filaments are the used in muscle contractions. The thick filaments and thin filaments slide along each other during a muscle contraction.
4. Lactic acid is removed from muscles when there is an increased amount of blood flow (usually during exercise).
5. Posture is the way a person holds their body when sitting or standing.
6. Varicose veins occur when the veins are weakened and become twisted over time. Normal veins will flow in one direction and there is no back flow because of the valves. When veins are weakened and the valves don’t work properly, the blood can collect in your legs.
7. Antagonistic muscles pair with agonist muscles (best example is the bicep-tricep pair). This means that as one muscle contracts, the other will relax.
