1 Human Physiology in the Development of Performance

2 Today’s Objectives Correctly identify the performance criteria for LO2 Correctly identify the function of the respiratory system Correctly describe the pathway of air Correctly describe the process of pulmonary diffusion Correctly describe the stages that occur in breathing in and breathing out Correctly describe the adaptations that take place in the respiratory system with sport and exercise

3 Human Physiology in the Development of Performance D Learning Outcome 2 a)The structure of the main components of the cardio-respiratory system is correctly described b)The function of the main components of the cardio-respiratory system are accurately described

4 Human Physiology in the Development of Performance D We are going to separate the Cardio Respiratory system into 2 parts In general terms: –Cardio: Heart –Respiratory: Lungs

5 Human Physiology in the Development of Performance D Respiratory System Question What is the main function of the respiratory system? Answer  To breathe in oxygen and breathe out carbon dioxide

6 Anatomy of the Respiratory System StructureDescription Nasal PassageNose Oral CavityMouth PharynxFunnel shaped tube allowing air to go into the windpipe LarynxVoice Box TracheaWindpipe BronchiSub-divisions of windpipe

7 Anatomy of the Respiratory System StructureDescription LungsCone shaped organs of the respiratory system HeartMuscular organ of the cardiovascular system RibsFlat bones that protect the heart and lungs Intercostal muscles Muscle that pull on the rib cage causing it to move CartilageConnective tissue that joins the ribs onto the sternum

8 Anatomy of the Respiratory System StructureDescription BronchiolesSmall tube like subdivisions of the bronchi DiaphragmMuscle at the bottom of the rib cage which assists during breathing AlveoliBunch of grape like structures where pulmonary diffusion takes place

9 The Respiratory System Intercostal muscles Cartilage Bronchioles Diaphragm Alveoli

10 Pathway of Air Task In your pairs look at the diagram of the respiratory system Taking into account gravity Make a list of the respiratory structures in the order that you think the air passes through them

11 Pathway of Air Oral Cavity/Nasal Passages Pharynx Larynx Trachea Bronchus Bronchioles Alveoli – where pulmonary diffusion occurs

12 What is Pulmonary Diffusion? Pulmonary Diffusion is the name for the process of gas exchange which occurs in the lungs It has 2 main functions: 1.To replenish the blood with oxygen where it can be transported around the body 2.To remove carbon dioxide from the blood so we can breathe it out

13 Pulmonary Diffusion During pulmonary diffusion the gases (O2 and CO2) always travel from an area of high concentration to an area of low concentration Until there is an equal balance of both gases in the blood

14 Human Physiology in the Development of Performance D Breathing in and Breathing Out Q) How many breaths does the average person take at rest per minute? A) Q) How many breaths do you take at rest in the average minute? A)

15 Breathing in and Breathing Out AThe intercostal muscles and the diaphragm relax BThe diaphragm contracts and flattens CThe volume of the lungs decreases DThe internal pressure of the lungs increases above that of the external air pressure EThe intercostal muscles contract pulling the ribs up and out FThe greater air pressure outside forces air into the lungs GThis increases the volume of the lungs and decreases the air pressure inside them HAir is forced out of the lungs

16 Breathing In and Out Firstly decide which statements are involved with breathing in and which are involved with breathing out Then establish a logical order of events for each phase of breathing Hint - gas always moves from areas of high pressure to areas of low pressure

17 Breathing In and Out AThe intercostals muscles and the diaphragm relax BThe diaphragm contracts and flattens CThe volume of the lungs decreases DThe internal pressure of the lungs increases above that of the external air pressure EThe intercostals muscles contract pulling the ribs up and out FThe greater air pressure outside forces air into the lungs GThis increases the volume of the lungs and decreases the air pressure inside them HAir is forced out of the lungs

18 Breathing In and Out AThe intercostals muscles and the diaphragm relax BThe diaphragm contracts and flattens CThe volume of the lungs decreases DThe internal pressure of the lungs increases above that of the external air pressure EThe intercostals muscles contract pulling the ribs up and out FThe greater air pressure outside forces air into the lungs GThis increases the volume of the lungs and decreases the air pressure inside them HAir is forced out of the lungs Out In Out In Out

19 Breathing In and Out AThe intercostals muscles and the diaphragm relax BThe diaphragm contracts and flattens CThe volume of the lungs decreases DThe internal pressure of the lungs increases above that of the external air pressure EThe intercostals muscles contract pulling the ribs up and out FThe greater air pressure outside forces air into the lungs GThis increases the volume of the lungs and decreases the air pressure inside them HAir is forced out of the lungs

20 Breathing In and Out AThe intercostals muscles and the diaphragm relax BThe diaphragm contracts and flattens CThe volume of the lungs decreases DThe internal pressure of the lungs increases above that of the external air pressure EThe intercostals muscles contract pulling the ribs up and out FThe greater air pressure outside forces air into the lungs GThis increases the volume of the lungs and decreases the air pressure inside them HAir is forced out of the lungs Out 1 In 1 Out 2 Out 3 In 2 In 4 In 3 Out 4

21 Human Physiology in the Development of Performance D Breathing In B The diaphragm contracts and flattens E The intercostals muscles contract pulling the ribs up and out G This increases the volume of the lungs and decreases the air pressure inside them F The greater air pressure outside forces air into the lungs

22 Human Physiology in the Development of Performance D Breathing Out A The intercostals muscles and the diaphragm relax C The volume of the lungs decreases D The internal pressure of the lungs increases above that of the external air pressure H Air is forced out of the lungs

23 Adaptations to the Respiratory with Exercise Increased ability to take in more air due to increases in strength or endurance of intercostals muscles Increased efficiency of oxygen uptake by blood (pulmonary diffusion) Increased alveoli surface area

24 You should now be able to Correctly identify the performance criteria for LO2 Correctly identify the function of the respiratory system Correctly describe the pathway of air Correctly describe the process of pulmonary diffusion Correctly describe the stages that occur in breathing in and breathing out Correctly describe the adaptations that take place in the respiratory system with sport and exercise
