Scenario You are working as a research worker and have been asked to produce a report on regulation of the fluids in human body as part of an application for a research grant. Task 1 P1 Describe the main sites of re- absorption in the kidney You are going to perform a dissection of a kidney. You will be required to identify the different parts of the kidney. Your teacher will observe the dissection and complete an observation task assessing your dissection skills. Due date: Task 2 This provides evidence for P1 P1 Describe the main sites of re- absorption in the kidney Produce a poster on the kidney. Your poster needs to show a labelled diagram of the gross structure of the kidney and a labelled diagram of a nephron. Due date: This provides evidence for P1 P1 Describe the main sites of re- absorption in the kidney Task 3 M1 Describe how re- absorption occurs in each of the main sites Produce a series of diagrams explaining how ultrafiltration and selective absorption occurs in the kidneys. Your diagrams show clearly show the following: An introduction explaining the function of the kidney What ultrafiltration is and where it occurs What substances are filtered from the blood How selective reabsorption occurs How water is reabsorbed in the Loop of Henle How the structures within the kidney interrelate to allow them to function. Due date: Task 4 This provides evidence for P1 + M1 P2 Outline the importance of regulating body fluids in the body You are going to investigate practically a method of transport across a membrane. The effect of size on uptake by diffusion. You are going to carry out the investigation and will be assessed on your practical skills during the experiment. You are going to investigate how the SA:Volume Ratio of an organism affects its uptake. You then need to complete the questions on the bottom of the sheet. Due date: 2 This provides evidence for P2 BTEC Level 3 Subsidiary Diploma in Applied Science (Applied Biology) Task 5 Unit 12: Physiology of Human Ragulation and Reproduction: Regulation of the body fluids P2 Outline the importance of regulating body fluids in the body You are going to investigate practically a method of transport across a membrane Osmosis. You are going to investigate the solute potential of cell sap of plant epidermal cells. You will investigate how sugar solution affects the plasmolyses of cells. You need to present your investigation in the form of a written investigation following the given structure. Due date: Task 6 This provides evidence for P2 P2 Outline the importance of regulating body fluids in the body You are going to carry out an investigation looking at urine from different patients. You are going to perform a series of tests on each of the samples and draw conclusions based on what is wrong with each of the patients. You will be required to write a brief report on each patient stating your findings. Due date: Task 7 This provides evidence for P2 D1 Explain how the body maintains the correct acid-base balance You need to demonstrate your understanding of electrolytes in the body and how changing levels of certain electrolytes affect the balance within the body. Complete the worksheet to show the function and levels of the following √ Sodium √ Potassium √ Chloride √ Bicarbonate Due date: This provides evidence for P2 + D1 Task 8 D1 Explain how the body maintains the correct acid-base balance Following your lesson on acid-base mechanisms you need to complete the worksheet demonstrating an understanding of the following areas; √ What a buffer is, where they are found in the human body, what they do to assist in the maintenance of homeostasis and some examples of buffers within the body. √ How hydrogen ions are produced during metabolism and the relationship between hydrogen ions and pH. √ How the following act as buffers o Haemoglobin o Carbonic acid o Proteins o Phosphate Due date: This provides evidence for D1 Evidence checklist [Summarise evidence required, e.g. ‘leaflet’, ‘presentation notes’ etc.] [tick boxes] Dissection of the kidney Poster on the kidney Diagrams of ultrafiltration and selective absorption Diffusion practical Osmosis practical Urine testing Worksheet on electrolytes Worksheet on acid-base mechanisms 3 Unit 12: : Physiology of Human Ragulation and Reproduction: Regulation of the body fluids BTEC Level 3 Subsidiary Diploma in Applied Science (Applied Biology Sources of information Textbooks Adds J et al – Respiration and Coordination (Nelson Advanced Science: Biology Series) (Nelson Thornes, 2005) ISBN 9780748774890 Boyle M et al – Human Biology (Collins Advanced Science Series) (Collins Educational, 2002) ISBN 9780007135998 Johnson M D – Human Biology: Concepts and Current Issues, 3rd Edition (Benjamin Cummings, 2005) ISBN 9780805372014 Pickering W R – A-level Advanced Human Biology Through Diagrams (Oxford University Press, 2001) ISBN 9780199141968 Tortora G J – Principles of Anatomy and Physiology (John Wiley & Sons, 2005) ISBN 9780471718710 Journals The Journal of Physiological Sciences The Journal of Physiology – Published on behalf of the Physiological Society Websites www.cellsalive.co.uk Biology site www.hse.gov.uk/pubns/indg342.pdf Health and safety guidance on blood borne viruses www.innerbody.com/htm/body.html Human anatomy online www.kidney.niddk.nih.gov/Kudiseases/pubs/yourkidneys The kidneys and how they work www.merck.com/mmhe/sec12/ch159/ch159a.html Disorders of nutrition and metabolism www.merck.com/mmhe/sec22/ch241/ch241e.html Menstrual cycle www.s-cool.co.uk/alevel/biology.html Social biology revision www.womens-health.health-cares.net/female-fertility-tests.php Fertility tests This brief has been verified as being fit for purpose Assessor Ms Fensome Signature Internal verifier Signature 4 Date 06/07/2015 Date 06/07/2015 Mrs Turner-Smith BTEC Level 3 Subsidiary Diploma in Applied Science (Applied Biology) Unit 12: Physiology of Human Ragulation and Reproduction: Regulation of the body fluids Assessor's comments Qualification Unit number and title Criteria reference P1 P2 M1 D1 BTEC Level 3 Subsidiary Diploma in Applied Science Unit 12 Physiology of human regulation and reproduction Assessor name Ms Fensome Learner name To achieve the criteria the evidence must show that the learner is able to: Achieved?
