This detailed lesson has been planned to cover the 1st part of specification point 5.1.2 © of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the gross structure of the kidney included the detailed structure of the nephron. The lesson was designed at the same time as the other lessons in this topic on ultrafiltration, selective reabsorption and osmoregulation so that a common theme runs throughout and students can build their knowledge up gradually and develop a deep understanding of this organ.
Students will come to recognise the renal cortex and renal medulla as the two regions of the kidney and learn the parts of the nephron which are found in each of these regions. Time is taken to look at the vascular supply of this organ and specifically to explain how the renal artery divides into the afferent arterioles which carry blood towards the glomerulus and the efferent arterioles which carry the blood away. The main task of the lesson challenges the students to relate structure to function. Having been introduced to the names of each of the parts of the nephron, they have to use the details of the structures found at these parts to match the function. For example, they have to make the connection between the microvilli in the PCT as a sign that this part is involved in selective reabsorption.
This lesson has been designed for students studying on the OCR A-level Biology course

5.1.2: Excretion as an example of homeostatic control (OCR A-level biology)
All 9 lessons included in this bundle are filled with a variety of tasks to maintain engagement whilst covering the detailed content of module 5.1.2 of the OCR A-level biology specification. There are also multiple understanding checks and prior knowledge checks, with answers embedded into the PowerPoint, which allow the students to assess their progress against the current topic and test their ability to make links to previously covered content. This module titled "Excretion as an example of homeostatic control", considers the removal of the products of cell metabolism and explores the role of the liver, kidneys (and skin) in this process. The functions of the liver and structure of the kidney lessons have been uploaded for free, so you could download these first if you would like to view the quality of this bundle. The specification points not directly covered by the lessons in this bundle are: (b) (ii) [c) (ii) [c] (iii) (f)

Homeostasis, Excretion, Neuronal and Hormonal communication (OCR A-level Biology A)
This bundle of 20 lessons covers the majority of the content that's included in modules 5.1.1 - 5.1.4 of the OCR A-level Biology A specification. All of the lessons are highly detailed and have been planned at length to ensure that they are filled with a wide range of tasks to engage and motivate the students whilst checking on their understanding. The following specification points are covered by the lessons in this bundle: 5.1.1: Communication and homeostasis * The communication between cells by cell signalling * The principle of homeostasis * The physiological and behavioural responses involved in temperature control in endotherms and ectotherms 5.1.2: Excretion as an example of homeostatic control * The functions of the mammalian liver * The gross structure and histology of the kidney * The processes of ultrafiltration and selective reabsorption * The control of the water potential of the blood * The effects of kidney failure and its potential treatments 5.1.3: Neuronal communication * The roles of mammalian sensory receptors in converting stimuli into nerve impulses * The structure and functions of sensory, relay and motor neurones * The generation and transmission of nerve impulses in mammals * The structures and roles of synapses in transmission 5.1.4: Hormonal communication * Endocrine communication by hormones * The structure and functions of the adrenal glands * The structure of the pancreas * The regulation of blood glucose concentration * The difference between diabetes mellitus type I and II * The potential treatments for diabetes mellitus It is estimated that it will take in excess of 2 months of allocated A-level teaching time to cover the detail included in these lessons If you would like to sample the quality of the lessons in this bundle, then download the following lessons as they have been shared for free: * The principles of homeostasis * Temperature control in ectotherms * The functions of the liver * The structure of the kidney * The generation and transmission of nerve impulses * Endocrine communication
