Assignment 12.1 Brief
Unit number and title / Unit 12: Physiology of Human Regulation and Reproduction

Assessor name / Ms Fensome
Assignment title / Regulating body fluids
The purpose of this assignment is to demonstrate knowledge and understanding of how bodily fluids are regulated, by studying the urinary system.
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: This provides evidence for P1
Task 2 / 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
Task 3 / P1 Describe the main sites of re- absorption in the kidney
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: This provides evidence for P1 + M1
Task 4 / 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: This provides evidence for P2
Task 5 / 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: This provides evidence for P2
Task 6 / 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: This provides evidence for P2
Task 7 / 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
