11 Lesson 1:

12 Learning Outcomes The aim of this lesson To know how our bodies are made up of cells, organs and systems Success Criteria What you will learn in this lesson I can remember the order - cells- tissue organ - system I can give at least 2 examples of body systems and their function I can also describe what the respiratory and circulatory system do

13 Activities Brainpop: Human Body - All systems go Body Systems powerpoint go through some of the body systems Body Systems cards to recap

14 Body organs

15 Body organs

16 Homework due: write the due date in Choose one of the Body systems and make an A4 poster about it. Include A labelled diagram The organs involved What the function is One amazing fact

17 Homework due: 00/00/0000 Fill in the missing labels This body system is called system. Its function is to enable us to get into the blood and to remove from the blood. Heart ( in circulatory system) diaphragm lung Carbon dioxide oxygen respiratory

18 Lesson 2-3

19 Circulatory System Respiratory system

20 Can you label the diagram? Fill in the labels Bronchiole Right Bronchus Alveoli Intercostal muscles Heart Trachea Diaphragm

23 Add in the arrows to show the direction of blood flowing through the body.

24 Investigating the effect of exercise on heart rate. Introduction Have you ever wondered how many times your heart beats in a day, a month, a year or will beat in total throughout your life? Over an average lifetime, the human heart beats more than 2.5 billion times. For a person to keep their heart healthy, they should eat right, not smoke and get regular exercise.

25 Preparation Equipment Handling Practice finding your pulse. Use the first two fingers of one hand to feel your radial pulse on the opposite wrist. You should find your radial pulse on the "thumb side" of your wrist, just below the base of your hand. Practice finding your pulse until you can do it quickly. (You can alternatively take your carotid pulse to do this activity, but be sure you know how to safely take it and press on your neck only very lightly with your fingers.) OR use the pulse meter this will also measure your oxygen saturation level.

27 Preparation Measure your resting heart rate, which is your heart rate when you are awake but relaxed and not moving. To do this, take your pulse when you have been resting and multiply the number of beats you count in 10 seconds by six. This will give you your resting heart rate in beats per minute (bpm). What is your resting heart rate? Or read of the pulse meter that will calculate bpm for you. Write it down. My resting heart rate is bpm You will be measuring your heart rate during different types of physical exercises over a period of 2 minutes.

28 Method What are we going to do.? You will be measuring your heart rate during different types of physical exercises over a period of 2 minutes. Choose 1 of these activities to start with Star jumps Jogging on the spot Sit ups burpees Carry out the activity for 2 minutes. Stop and immediately take your pulse rate. Wait until your pulse rate returns to your resting heart rate and then repeat with another activity.

31 Pulse rate Beats per minute Column2 Column1 Column Resting Burpees Star Jumps Skipping Activity type

32 Conclusion what do our results show us? Write a summary to describe the effect of exercise on heart rate? How long did it take to return to your resting heart rate each time? What does this tell us? How could you have improved your results to make them more reliable? How does regular exercise help to keep your heart healthy what exercise is recommended for someone your age? How does that compare with what you actually do? Find out about medical conditions that affect the respiratory and circulatory systems - what can be done to prevent people developing these conditions?

33 Extension work Use National 5 text book or Higher Human Text book or take out some books from the library to help with your research Find out about any from heart disease, strokes, lung cancer, emphysema, DVT. What lifestyle choices can help to reduce the likelihood of suffering from these diseases?

34 Guidelines for 5- to 18-year-olds To maintain a basic level of health, children and young people aged 5 to 18 need to do: at least 60 minutes of physical activity every day this should range from moderate activity, such as cycling and playground activities, to vigorous activity, such as running and tennis on three days a week, these activities should involve exercises for strong muscles, such as push-ups, and exercises for strong bones, such as jumping and running Many vigorous activities can help you build strong muscles and bones, including anything involving running and jumping, such as gymnastics, martial arts and football. Children and young people should reduce the time they spend sitting watching TV, playing computer games and travelling by car when they could walk or cycle instead.

35 Exit Pass To leave this class you must write down one thing you have: (1) Newly learnt (did not know before) (2)Don t understand/need to revise And hand it in.
