Body in Action 2.0 / 5 based on 2 ratings ? BiologyNational 5SQA Created by: Lisa DuncanCreated on: 03-10-12 23:28 What does the skeleton provide? S.P.A.M.M- Support, protection and attatchment of muscles for movement. 1 of 31 What is the range of movement in a ball and socket joint? three planes of movement 2 of 31 What is the function of the ligament? Attatches bone to bone 3 of 31 What is the function of cartilage? Acts as a shock absorber and reduces friction. 4 of 31 What are the parts of a synovial joint? Cartilage, ligament, synovial fluid and synovial membrane 5 of 31 What is bone composed of? Flexible fibres and hard minerals ( living cells and calcium phosphate) 6 of 31 What attatches muscle to bone? Tendons 7 of 31 Why are tendons elastic? So all muscular contractions are passed on to the bone. 8 of 31 Name the structures of the lungs Trachea, bronchi, bronchioles and alveoli. 9 of 31 Explain the function of the cilia and mucus in the trachea and bronchi. The mucus traps dirt and germs and the cilia beat rhthmically to push dirt and germs to the mouth and nose. 10 of 31 What four features make the lungs efficients in gas exchange. Large surfuce area of alveoli, moist lining, very thin walls, rich supply of blood cappillaries. 11 of 31 Name the four chambers of the heart Right atrium, left atrium, right ventricle, left ventricle. 12 of 31 State the blood flow through the heart. Right atrium > right ventricle > lungs > left atrium > left ventricle > aorta > body > vena cava 13 of 31 Name the four main blood vessels in the body Pulmonary vein, pulmonary artery, aorta and vena cava 14 of 31 What are arteries? Blood vessels which carry blood AWAY from the heart 15 of 31 Where does gas exchange in the blood vessels take place? Cappillaries 16 of 31 Is blood at low or high pressure in veins? Low 17 of 31 What indicates blood is flowing through an artery? A pulse. 18 of 31 What do red blood cells transport? Oxygen 19 of 31 Where is haemoglobin found? Red blood cells. 20 of 31 What is the function of the retina? Changes light energy to electrical impulses. 21 of 31 What is the function of semi- circular canals? Filled with liquid so when the head moves the brain detects this and helps with balance. 22 of 31 What is the central nervous system composed of? Spinal cord and brain. 23 of 31 What is a reflex action? An automatic response to a stimulus which does not directly involve the brain. 24 of 31 What are the three main parts of the brain? Cerebrum, cerebellum and medulla. 25 of 31 What controls heart and breathing rate? medulla 26 of 31 What causes muscle fatigue? Prolonged excercise. 27 of 31 If there is a lack of oxygen, muscles breakdown glucose to lactic acid, what is this process? Anaerobic respiration. 28 of 31 What is oxygen debt? The amount of oxygen required to breakdown the lactic acid 29 of 31 What is recovery time? The time taken for breating, pulse and lactic acid rates to return to normal. 30 of 31 Who has a shorter recovery time? : trained or untrained person? Trained person 31 of 31
