2.3 Explain how the body coordinates its internal activities
• Homeostasis
• Principle of feedback loops

For the human body to function, cells within the body have to work and function correctly. Tissues, cells and organs all have different jobs with very different functions. The cells must have an internal environment which has to be stable to suit them for them. This enables survival for example things necessary are oxygen, nutrients or the removal of waste products. This ensures the human body is healthy and is able to function. This process where the body can control this internal environment no matter what is going out in the external environment this is known as homeostasis. Homeostasis involves the stability of equilibrium within a cell or within the human body. Homeostasis is maintaining a constant environment within the body for example homeostasis is very important making sure our bodies have the correct levels of oxygen, carbon dioxide, water, and maintain a correct body temperature. Homeostasis is vital to ensure all living things survival, keeping a stable and balanced internal environment which can constantly change within and out of the cell; this is known as homeostatic regulation. Homeostasis can be recognised as a dynamic equilibrium or steady state due to within a cell every mechanism that is kept alive is a …show more content…

(1)………………………… (2)……………………………… | | Unit AimThis unit provides the learner with the understanding and skills to plan strategies to improve an organisation’s supply chain.Unit introductionThis unit focuses on how the concept of supply chain management and logistics is based on the idea that every product that reaches an end user represents the combined effort of multiple organisations which make up the supply chain and that until recently, most organisations paid attention to only what was happening within their own business. Few organisations understood, much less managed, the entire chain of activities that ultimately delivered products to the final customer. This resulted in ineffective supply chains.In this unit, learners will develop the knowledge that, today, many organisations realise that effective management of supply chain activities can lead to increased customer value and achieve sustainable competitive advantage. Supply chain activities cover everything from product development, sourcing, production and logistics, to the information systems needed to coordinate these activities.Learners will discover that the organisations that make up the supply chain are ‘linked’ through...

...890 stores that consist of 547 supermarkets and 343 convenience stores. The company has 150,000 employees and serves more than 19 million customers a week (Company Overview, 2011, online). Sainsbury’s has a range of stakeholders to deal with. A stakeholder can be defined as “someone who has invested money into something, or has some important connection with it” (Chorley et al, 2008, p.2). According to Kozami (2002) stakeholders can be divided into two categories: internal and external. An internal stakeholder for the company is someone who works for the company and therefore is interested in various aspects of the business. External stakeholder, on the other hand, is someone who is interested in the performance and other aspects of the business, even though the individual does not work for the company. Sainsbury’s internal stakeholders can be external stakeholder of the company at the same time.
