  4. 4. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Why do humans need a transport system? Because of the numerous complex physiological activities occurring within each cell, humans have a wide variety of materials that need to be transported in/out of cells and around their body. 4
  5. 5. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? What needs to be transported? Wastes: e.g. Carbon dioxide from cells to lungs and urea to kidneys. Hormones: e.g. insulin, adrenaline - from endocrine glands to target organs. Antibodies: to where needed to fight infections. Blood proteins: to where needed. Blood cells: to carry oxygen or carbon dioxide; provide defense against germs; and to help with clotting of blood at wound sites. Nutrients: to all cells. 5
  6. 6. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Why do humans need a transport system? Diffusion is adequate to supply the transport needs of single-celled organisms like Amoeba, shown in the diagram. But … diffusion is effective only over short distances and is relatively slow! Humans need to take in O2, nutrients from their surroundings, to pass out waste, e.g., CO2, urea into their surroundings and transport other substances to various body cells. 6
  7. 7. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Why do humans need a Transport System? • The interior cells of multicellular animals, like humans, are too far from the body surface for us to rely on diffusion to bring oxygen and nutrients to body cells and remove metabolic waste. • In other words, our surface area is too small in relation to the large volume of our body for diffusion to be effective. A transport system thus becomesA transport system thus becomes necessary!necessary! 7
  8. 8. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? The Human Transport System • In humans, materials are transported around the body by the circulatory or cardiovascular system. • It is a closed system, i.e., blood, the transport medium, circles the body within a network of blood vessels. • It acts as a “pick up and delivery” system for various substances. 8

Note the structure of blood vessels at http://www.youtube.com/watch?v=3ffSxq9iyB8&feature=related /watch?v=HNuPWdfjDoc&feature=related The relatively thick muscular and elastic layers enable arteries to withstand the high pressure as the heart forcibly pumps blood through them to get to all body parts. Pressure is high in arteries to move blood to all body parts. 31
  32. 32. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Blood Vessels Types of Blood Vessels Movement of blood in veins is helped by contractions of adjacent muscles and aided by valves inside the veins. Click the link to see how valves in veins work: http://www.youtube.com Capillaries are fine tubes that form a network that comes into direct contact with body cells.  The wall of a capillary is very thin allowing diffusion into/out of blood to take place quite easily. Watch the video at the following link: http://www.youtube.com/watch?v=Q530H1WxtOw& 32
  33. 33. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Blood Vessels How do Blood Vessels relate to each other? What is the direction of blood flow through a capillary network? 33
  34. 34. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Blood Vessels Blood flow through the capillaries Note that our blood does not come into direct contact with the cells it supplies. Interstitial fluid bathes the cells in the tissue spaces and substances in it can enter the cells by diffusion or by active transport; e.g. CO2 can diffuse out of cells and into the interstitial fluid and then into the blood in the capillaries. So, it is the interstitial fluid that actually brings to cells all of the needed materials and takes away their waste products. 34

  36. 36. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Types of Circulation 1. PULMONARY CIRCULATION: The heart pumps deoxygenated blood to the lungs via Pulmonary arteries, then oxygenated blood returns from the lungs to the heart via Pulmonary veins. Visit this website for more information: http://www.pbs.org/wnet/redgold/journey/circulatio Read about the other two circulations on the next slide! 36
  37. 37. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? Types of Circulation 2. SYSTEMIC CIRCULATION: Oxygenated blood is pumped forcefully out of the heart into the Aorta then via other arteries to all parts of the body. Deoxygenated blood collected from various cells returns to the heart via the Venae cavae to be pumped out to the lungs for oxygenation 3. CORONARY CIRCULATION: The heart itself has its own supply of blood vessels which bring nutrients and oxygen to the cardiac muscle cells and removes waste. 37

ACTIVITY 1: Heart structure Type the name of each part labeled A - M on the diagram. Click CHECK for feedback. Discuss any incorrect labels with your teacher. 41 A – Pulmonary artery B – Pulmonary vein C – Left atrium D- Heart tendons E- Left ventricle F- Descending aorta G – Aortic (semi-lunar) valve H – Right ventricle I – Inferior Vena Cava J – Pulmonary (semi-lunar) valve K – Right atrium L – Superior vena cava M – Aortic arch of the aorta
  42. 42. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? ACTIVITY 2: Heart structure and blood vessels Answer questions 1 - 4 below in you notebook or in the box below. 1. Why are the left and right sides of the heart separated? 2. How is the pulmonary artery different from other arteries? 3. Do the pulmonary veins carry oxygenated or deoxygenated blood? 4. Why is the left ventricle thicker than the right ventricle? 42 1. The left and right sides of the heart are separated to prevent oxygenated and deoxygenated blood from mixing. 2. The pulmonary artery carries deoxygenated blood while other arteries carry oxygenated blood. 3. The pulmonary veins carry oxygenated blood from the lungs to the heart. 4. The left ventricle is thicker than the right ventricle because it has to contract forcefully to pump blood into the aorta to be distributed to the body.
  43. 43. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? ACTIVITY 3: Your heart-beat and your pulse  Try to locate your pulse and count the pulse rate/ minute.  Ensure you use the correct fingers! 43
  44. 44. OBJECTIVES The Human Transport System The Human Heart Blood Vessels Types of Circulation ACTIVITIES Your heart beat The Lymphatic System Why do humans need a transport system? ACTIVITY 4: Heart rate From what you have already learned about how your circulatory system works and its relationships with other body systems, why would your heart and pulse rate increase with exercise? 44 During exercise, the heart has to work/beat harder and more forcefully to pump blood faster around the body in order to: 1.deliver oxygen to the working muscles because oxygen is needed/involved in the respiratory activities that cause energy-release from stored nutrients in muscles and other cells and 2.remove carbon dioxide and other cellular wastes from the muscle cells

ACTIVITY 5 - Question 2: Circulation 46 Look at the diagram on the right. What is the main difference between the blood at 10 and at 6? Type your response to the question in the box below. Click CHECK for feedback. The blood at 10 is being returned to the heart from the cells of the lower body parts, so is deoxygenated and has a high concentration of CO2 from their respiratory activities. That blood might also have a lower concentration of urea and nitrogenous wastes as it might already have been filtered in the kidneys. The blood in 6 is strongly oxygenated.
