NEET BIOLOGY STUDY MATERIAL VII - OLYMPIAD CDF-1 TRANPORTATION AND ITS COMPONENTS 1. To avoid delay in transport of substances at cellular level, blood flows in a system called circulatory or transportation system. 2. Blood carries useful nutrients from one place to another. 3. Blood flows in blood vessels. 4. Heart exerts some pressure for the blood to flow into blood vessels. 5. Blood is a fluid connective tissue. 6. Oxygen is supplied to cells by the blood. 7. Haemoglobin helps for transportation of oxygen. a. Haemoglobin pigment is red in colour. 8. In unicellular organisms, diffusion helps for transportation. 9. In higher animals trillions of cells are present.So, materials need to be transported to longer distances. 10. In animals, heart, blood, blood vessels are major components. 11. The heart exerts some pressure on blood vessels called pulse rate. 12. The pulse rate indicates heartbeat. 13. In eucalyptus tree water is transported up to 300ft. 14. Plants root show some special pressure called root pressure to transport water from root hairs to stem. 15. Small plants show root pressure and can supply water to all the parts of the body. SYNOPSIS-1 TRANSPORATION AND ITS COMPONENTS Introduction 1. All the living organisms need nutrients, liquids like water and gases like oxygen and carbon dioxide. 2. All the organisms would need to send these materials to all the body parts whether they are unicellular or multicellular organisms. 3. In unicellular organisms these materials may not have sent to larger distance. 4. In multicellular organisms these should sent to larger distance up to 100 feet for tallest plants. Transportation in lower organisms: 5. In amoeba, sponges, all the materials are transported through Brownian movement by the principle of diffusion and osmosis.
VII - OLYMPIAD NEET BIOLOGY STUDY MATERIAL 6. This kind of specialized system is called transportation 7. To avoid delay of transport of substances separate system is needed. Transportation in higher animals: 8. In higher animals with trillion of cells in their body adopt the method of diffusion and os mosis. Only for bulk movement. We eat solids, we drink, liquids, we breathe gases Components of circulation 9. Heart, blood, blood vessels, lymph, and lymphatic system are considered as components of transport system. 10. Heart exerts some pressure on blood vessels to pump blood 11. Blood transports useful nutrients to various cells. 12. Blood is considered as a fluid connective tissue 13. Blood is red in colour due to presence of haemoglobin 14. Have you ever observed that doctor holding fingers on patient wrist? Doctor finds out heart beat through pulse rate? 15. Rhythmical heart beat at different regions if the body is called pulse rate 16. Normal pulse rate in adults 60-100 17. Stethoscope helps in counting heart rhythms 18. Laennec discovered stethoscope 19. Lymph flows in separate system called lymphatic system. Lymph is colourless fluid 20. Blood cells produced from bone marrow 21. Transportation and its component in plants 22. Root show special pressure called root pressure helps for transportation of water and mineral salts.

The liquid portion of Blood is called plasma and solid part of blood constitutes blood cells or bold corpuscles. 3. The main components of blood are a. Plasma b. Red blood cells c. White blood cells d. Platelets. 4. Blood is red in colour due to presence of a pigment called haemoglobin. 5. Haemoglobin is an iron containing protein. 6. The average life span of red blood cells is 120 days.
