No. 762284-U) 14 UNIT 2 Theme: Life Science Humans notES The Human Skeletal System and Its Function 1 Skeletal system is the bone system of humans. 2 Every bone has a specific function. Bone Function Backbones Support the body Skull Protect brain Ribs Protect internal organs such as lungs and heart Leg and hand bones Supporting and movement 3 Joint is a meeting point of two or more bones. Hand bone Skull Backbone Leg bone Joints 4 Joints allow movement and elasticity of the body in certain ways. • Pivot Allows rotational or circular movement. Example: Neck joint • Ball and socket Allows movement in various direction. Example: Shoulder and hip joints • Hinge Allows one-way movement. Examples: Elbow, knee and finger joints 5 Without skeletal system, humans do not have upright body shape, cannot move and the internal organs are not protected. Human Blood Circulatory System 1 Blood circulatory system is a system that carries oxygen, nutrients, water and waste products in human body. 2 The blood circulatory system involves three main parts, which are lungs, heart and blood vessels. GLOBAL MEDIASTREET SDN. BHD.
© Global Mediastreet Sdn. Bhd. (Co. No. 762284-U) 15 Lungs are for absorbing oxygen into the blood vessels and removing carbon dioxide from the blood vessels Heart is for pumping blood rich in oxygen to the whole body and blood rich in carbon dioxide to the lungs Blood vessels are for transporting blood to the whole body 3 Blood circulation pathway in human body can be explain as in the diagram below. Blood rich in oxygen Blood rich in carbon dioxide Lungs Heart Body 4 Without blood circulatory system, oxygen cannot be supplied to the whole body and carbon dioxide cannot be removed from the body. Relationship between the Systems in Human Body 1 Every system in the human body is related to other system. 2 Examples of relationship: • When ribs (skeletal system) is broken, the function of the heart and lungs (blood circulatory system) will be disturbed. • When food is stuck in the throat (digestive system), trachea (respiratory system) will be blocked Food Trachea Oesophagus • When a leg bone (skeletal system) is broken, the leg will be swollen because the blood flow (blood circulatory system) is disturbed. 3 We must take care of all systems in the body so that our body can grow and function healthily, safely and perfectly. 4 Ways to take care of the systems in the body: • Do exercises and physical activities that are suitable with the age stage. • Practice healthy and balance diet. • Get enough rest and sleep. • Avoid bad habits such as smoking and drug addiction. • Handle emotional stress wisely. • Wash hands frequently. • Drink enough water. • Wear helmet or seat belt while riding vehicles.

No. 762284-U) 22 UNIT 3 Theme: Life Science Animals notES Survival of Animal Species 1 The survival of species of animals is defined as the ability of animals to maintain their species to prevent extinction. 2 Animals are created with specific characteristics to protect themselves from enemies. The characteristics include: (a) Have hard shells Examples: Turtle Horseshoe crab (b) Have stings that release venoms Examples: Scorpion Bee (c) Have sharp horns Examples: Deer Buffalo (d) Have strong leg muscles Examples: Horse Frog (e) Have hard scales Example: Crocodile 3 Some animals have specific behaviours to protect themselves against enemies. Examples: (a) Porcupines will raise the sharp spines on their bodies. (b) Pufferfish inflated their bodies that have sharp spine. (c) Lizards and octopuses detached their body parts to confuse the enemies. (d) Cuttlefish and octopuses spurt out black ink when being attacked by the enemies. (e) Pangolins and caterpillars rolled their body if they feel threatened. 4 Animals also have specific characteristics and behaviours to protect themselves during extreme cold season. (a) Animals in polar areas such as polar bears hibernate to reduce loss of energy. (b) There are animals that are migrate to the hotter countries or areas when the winter comes. For example, sandpipers, milky storks and whales. (c) The following table shows the example of animals at the poles and their specific characteristics for protection against extreme cold weather. Example of animal Specific characteristics Polar bear Thick fur Sea lion, walrus Small earlobes, have thick layer of fat under the skin Penguins Short and densed feathers GLOBAL MEDIASTREET SDN. BHD.
© Global Mediastreet Sdn. Bhd. (Co. No. 762284-U) 23 5 Animals that live in the areas of extreme hot weather have the following specific characteristics. (a) Camels have humps to store food and water in the form of fat. (b) Desert rats and desert fox have large ear lobes so that they can release more heat from the body. (c) Buffaloes, elephants and hippopotamuses wallow in mud or water to control their body temperature. 6 In addition to specific characteristics and specific behaviours, animals also protect eggs and young to ensure the survival of their species. 7 Animals that lay eggs protect their eggs. (a) Hiding the eggs in the soil or sand (b) Laying the eggs under leaves (c) Incubate the eggs (d) Lay a lot of eggs 8 Animals that give birth to young ensure the survival of their species by taking care and feed the young until they can find their own food. Example: The Food Relationship among Living Things 1 A food chain is the relationship of food among the living things that live in a habitat. 2 Example of a food chain in the forest: Grass Rumput Goat Kambing Tiger Harimau Grass Goat Tiger (a) A food chain consists of producer and consumers. (b) The arrows in the food chain (→) means ‘eaten by’. (c) The producer obtaining energy from the Sun by carries out photosynthesis. The energy is transferred when a consumer eats the producer and when the consumer is eaten by another consumer. (d) Therefore, a food chain also represents the food relationship between living things in term of energy transfer. 3 Food web is a combination of two or more food chains in a habitat. 4 - 12 Padi Belalang Tikus Ular Burung Helang Grasshopper Bird Eagle Snake Rat Paddy (a) The changes that happen to the population of certain living thing will give impact to other living things in the habitat. (b) Based on the above food web, (i) when the production of paddy decreases, the populations of grasshoppers, rats and birds will reduce.
