1. The Muscular System Learning Objectives – We are developing our knowledge of the Muscular System Push yourself today to go above your target grade

2. Cardiovascular Recap GradeQuestionMark Scheme C Circle the 3 parts of the Cardiovascular system. (1 Mark) Then, list 2 Short Term and 2 Long Term effects of Exercise on the Cardiovascular System. (2 marks) Heart Lungs Biceps Blood Vessels Blood Oxygen Short Term – 1. Increase HEART RATE 2. INCREASE CARDIAC OUTPUT(C.O) Long Term – 1. Decrease RHR 2. Increase STROKE Volume B Explain the reason for the increase in Cardiac Output when you start exercising? (2 Marks) (Clue – Increase HR Cardiac Output = HR x Volume of blood each beat Increase in HR / more demand for oxygen at working muscles / More beats per minute means = more blood pumped per minute than when at rest. A Explain how Stroke Volume is affected by the amount of Cardiac Muscle surrounding the heart. (2 Marks) Stronger cardiac muscle / stronger contractions / more blood pumped PER BEAT. A*A* Analyse the importance of diet in relation to a healthy cardiovascular system. (3 Marks) Cholestorol Lipoprotein – HDL good for cholestorol LDL bad (fatty foods) Poor diet can lead to fatty deposits / increase in blood pressure.

6. Deltoid Trapezius Latissimus Dorsi Pectorals Abdominals Biceps Tricpes Gluteals Quadriceps Hamstrings Gastrocnemius Starter – Use the clues to link the correct name of the muscle to the body

7. Watch the video and highlight important information. Please then answer the question below. Answer these questions – 1.Muscles work in pairs – True or False 2. The AGONIST is the muscle that relaxes - True or False 3. Muscles are attached to bone by Tendons – True or False 4. The proper name for muscles working as pairs is – ANT_______________ 5. An ISOMETRIC movement involves a stationary contraction Explain how the Quadriceps and Hamstrings work together to make the leg bend at the knee. Draw a picture to help if needed. ________________________________________________________________ ________________________________________________________________ Analyse the muscles used by Usain Bolt during the whole of a Sprint race.

12. Read the BOXES and place a number next to the letter in the order you believe they go. Exercise increases the body’s demand for oxygen and glycogen … …because the muscles need more energy to function… They are contracting and lengthening at an increased rate… When the demand becomes too high then lactic acid builds up until it is not possible to continue. Muscles can then ache and can cause cramp. Extra waste products are created when muscles work harder… …so more blood is required to take them away… It is possible to continue working aerobically as long as the intensity is not too high. Explain why a Warm up and cool down are vital for an athlete.

They are contracting and lengthening at an increased rate. Extra waste products are created when muscles work harder so more blood is required to take them away. It is possible to continue working aerobically as long as the intensity is not too high. When the demand becomes too high then lactic acid builds up until it is not possible to continue. Muscles can then ache and can cause cramp. Explain why a Warm up and cool down are vital for an athlete.
