| Question | Answer |
| Carbon dioxide is... | a poisonous by-product of respiration |
| Transport systems... | take materials to and from respiring cells |
| Oxygen is... | needed to release energy from glucose in the body |
| Respiration is... | the process that releases energy from food |
| Water is... | made when energy is released from food |
| Energy is... | needed to do ANYTHING |
| What is the equation for respiration? | Glucose+Oxygen --> Carbon dioxide+water+Energy |
| What are the lungs used for? | 1. To collect Oxygen from the air 2. To deliver carbon dioxide to the air |
| The lungs need... | 1. A large surface area for this swapping of gas to take place. 2. A good blood supply and circulatory system to move things around the body. 3. Ways to prevent the surfaces being clogged up with dust from the air. |
| Intercostal muscle... | The muscles found between the ribs and involved in ventilation |
| Bronchiole... | The smaller tubes that the bronchi split into. |
| Trachea... | The 'windpipe' - passage of air from outside to inside. |
| Diaphragm... | A muscular sheet at the bottom of the thorax and involved in ventilation. |
| Bronchi... | The two tubes ( one leading to each lung) that the trachea splits into. |
| Pleural membrane... | Moist membranes between the inside of the thorax and lungs that provide lubrication to prevent the lungs from 'sticking' |
| What is blood? | Blood is a mixture of different types of cells suspended in a straw coloured liquid called plasma. The main function of blood is to: carry oxygen and nutrients to the body cells: remove waste product: and protect the body against infection. Different components of the blood carry out different roles |
| Red blood cell: a) What does it look like? b) What is its primary role? c)Extra details... | a) It is shaped like flat disc with a dimple on each side. b) To carry oxygen and remove waste products. c) It contains a substance called haemoglobin, contains iron and helps to absorb oxygen. In the lungs oxyhemoglobin combine with oxygen haemoglobin. |
| White Blood cell: a) What does it look like? b) What is its primary role? c) Extra details... | a)They are spiky b)To protect the body from infection. c) The phagocytes kill the bacteria by eating them.The Lymphocytes kill the bacteria by a chemical called antibodies. |
| Platelets: a) What does it look like? b) What is its primary role? c) Extra details... | a) ________ b) To seal and clot the wound c) They play an important job by helping to clot at a wound to prevent any blood loss. |
| Plasma: a) What does it look like? b) What is its primary role? c) Extra details... | a) A straw coloured liquid. b) Carries all of the different types of cells contained in the blood. c) Carbon dioxide is produced as a waste product by cells in the body tissues, then dissolved in the blood plasma so it can be transported to the lungs. |
| What are the parts of the heart? | |
| What types of blood vessels are there? | 1) Artery 2) Vein 3) Capillary |
| Arteries have... | - Small lumen - Thick walls - Thick layer of muscle and elastic fibres. - Relatively thin walls |
| Veins have... | - Large lumen - Often have valves |
| Capillaries have... | - Walls a single layer thick - Tiny vessels with narrow lumen. |
