1. Tissues and Transplants Year 7 Unit A

2. Do Now: Glue in the picture of the person and label what you know (or think) you know Words: – Brain – Gullet (foodpipe) – Trachea (windpipe) – Lungs – Heart – Skin – Liver – Kidneys – Stomach – Small intestine – Large intestine

5. Brain Controls the body

6. Gullet (foodpipe) Allows food to travel from the mouth to the stomach

7. Trachea (windpipe) Carries air to the lungs

8. Heart Pumps blood

9. Skin For protection and feeling

10. Liver Make and destroy substances

11. Kidneys Clean the blood and make urine

12. Stomach Break-up food

13. Small Intestine Break up food and absorb it

14. Large Intestine Remove water from unwanted food

15. Matching Game Match the organ with the name and place into your notebook

16. Do Now: Why is the heart important?

17. Heart Your heart, made of muscle, pumps blood around your body via blood vessels (tubes). The heart is inside your chest, protected by bones - the ribs and breast bone. When the heart pumps, it beats - we measure the heartbeat via the pulse - easily found on your wrist and neck. Blood carries oxygen to the parts of the body that need it.

18. Find your pulse Your heart is about the size of your fist. In most adults it beats about 70 times a minute (70 bpm). In children and small animals, the heart beats faster.

20. Parts of a Heart

21. What is the heart made of? Tissues – Fat – Nerve – Muscle

22. Plant Tissues

23. Your Plant Draw and label your own plant, be sure to include the most important organs: – Root – Stem – Leaves/flower/fruit

24. Do Now: Come in, sit down. Pull out your green notebook and a pen. Nothing else should be on your table.

25. Do Now: Why are the lungs important? What organ do the lungs rely on to get oxygen?

26. Lungs Your lungs receive the air you breathe in through your nose. When you breathe in, the lungs puff-out or inflate, and deflate when you breathe out. From the air, they take the useful part - oxygen ( a gas ), and convert it for use in the body via the bloodstream. The blood swaps carbon dioxide ( the waste material ) for oxygen in the lungs. This is why the lungs are often said to convert gases.

27. You have 2 lungs. Your lungs are protected by your ribcage. Close-up, they look like a wet sponge. The left lung is smaller - to accommodate your heart (see the x-ray showing the heart). Your lungs are particularly vulnerable to breathing-in nasty substances - toxic chemicals, smoke from fires and cigarette smoke all damage your lungs.

29. Lung Dissection https://www.youtube.com/watch?v=9xhxALk9 gm8 https://www.youtube.com/watch?v=9xhxALk9 gm8 Write down observations

30. What did you observe? Discuss with the person next to you what observations you made during the video

31. Class Observations What did you learn from the dissection?

32. Do Now: Complete the heart analysis worsheet

33. Cells A cell is the very smallest unit of living matter. All living things, including plants and animals, are made up of cells.

34. Plant and Animal Cells The two kinds you need to be most familiar with are simple animal and plant cells.

35. Cell Membrane The cell membrane surrounds the cell and holds the cell together. It controls what chemicals can enter and leave the cell.

36. Nucleus The nucleus controls the cell. Inside the nucleus is DNA which contains genetic information.

37. Cytoplasm Cytoplasm is a jelly-like mixture of chemicals where most of the work of the cell takes place

38. Do Now: List what animal and plant cells have in common What does a plant cell have that an animal cell does not?

39. Tissue All tissues are made up of a group of the same type of cells

40. Types of Cells: People and Animals Ciliated Cell – found in the lung – Cliia wave together to move dirt out of the lungs

41. Muscle Cell Muscle Cell – allows us to move – Is able to change shape

42. Nerve Cell Nerve Cell – can be very long so that signals can be carried around the body quickly – Also called a neuron

44. Types of Cells: Plants Root hair cell – takes water out of the ground quickly – Gets water to the root

45. Palisade Cells Palisade Cells – packed with chloroplasts to help make food for the plant – Located near the top of the leaf

46. Xylem Cell Xylem Cell – join together to form hollow tubes, which carry water – Dead cell

47. Create a Table Cell Type, diagram, Uses, Where is it found

48. Do Now: 1.Which cell is found in plants and carries water through the stem? 2.What is special about this cell? 3.Which cell helps clean your lungs? 4.What is the part of the cell that helps with this cleaning?

49. Cell Division 7 Steps of Life Process 1.Move 2.Reproduce 3.Sense things 4.Grow 5.Respire 6.Excrete 7.Nutrition

50. Growing All living things grow – Cells need to divide in order to grow – Cell division – one cell splits to make 2 cells – Daughter cells – new cells created

51. Activity Cut out the cells A-F and put them in order of cell division. – Show me, once I have approved, glue into your book Cut out and answer questions 2 and 3 – Glue into your book when completed

52. Homework Worksheet on cell division – I will collect this next class

53. Do Now: Can xylem cells only be found in the stem?

54. How does it all work together? Organ system – A set of organs all working together

55. Organ Systems Circulatory system – moves blood through the body Digestive System – breaks down food Breathing system – Respiratory system Nervous Systems – carries signals around the body

56. What major organ is connected to each system? Circulatory system – Digestive System – Breathing system – Nervous Systems –

57. Activity Plant cells, tissues and organs follow a similar process called water transportation system. Make a diagram showing and label the different parts of a plant and the movement of water through the plant. Read page 19 What is a graft? Why are these useful?
