Section 51-1 VOCABULARY REVIEW 1. Target cells are the specific cells that are affected by a hormone. 2. A second messenger is an intracellular molecule that amplifies the signal of a first messenger. 3. A prostaglandin is a lipid that regulates the activity of cells that are in close proximity to its site of production. 4. Hormones are molecules that are secreted in small amounts‚ circulate in the bloodstream‚ and affect distant target cells. MULTIPLE CHOICE 1. d 2. c 3. a 4. c 5. c SHORT ANSWER

"Explain the concept of homeostasis with reference to the control of heart rate‚ breathing rate‚ body temperature and blood glucose levels" P5 Homeostasis is where the body keeps a constant internal environment. This involves all the metabolic processes taking place In the body as well as the blood‚ tissue fluid and all the contents in the body ’s cells. There are a range of variables from heart rate to the blood glucose levels that the body will take into account. Negative feedback will occur

the body should equal the amount of water leaving the body. -Control of fluid balance is maintained by: -The thirst mechanism in the hypothalamus‚ the osmoreceptor cells of which sense the internal environment -the hormone‚ antidiuretic hormone (ADH)‚ which controls the amount of fluid leaving the body in the urine -The hormone aldosterone‚ which determines the reabsorption of both sodium ions and water from the kidney tubules -The hormone atrial natriuretic peptide (ANP) is a hormone synthesized

The Mechanics of Water The Science of Nutrition Perhaps you have heard the phrase “water is life”. When it comes to the human body‚ nothing could be more accurate. The system of fluids in the body that water affects controls everything from nerve impulse to movement; it is even part of the very structure of our bodies. The following will discuss the vital connection between different systems in the body and how they use water to maintain proper health and function. We will discuss what happens

| Functions | Adrenocorticotropic hormone (ACTH) | ACTH stimulates the cortex to secrete hormones called glucocorticoids. Like cortisol. Which regulates glucose‚ protein‚ and fat metabolism‚ and response to stress. | Antidiuretic hormone (ADH) | ADH regulates water retention in the kidneys‚ reduces urine volume‚ and helps prevent dehydration. Also a brain neurotransmitter. | Follicle stimulating hormone (FSH) | The pituitary secretes FSH. It stimulates the sex hormone estrogen and development

Name : Dania Annuar Class : M11G Title : Determination of Chloride in Urine in Different Circumstances Aim: To determine the chloride content by titrating mixtures of urine against potassium thiocyanate under in different circumstances. Research Question: How do different conditions of urine samples collected affect its concentration of chloride which is measured by titrating the mixture of urine with potassium thiocyanate until it turns red? Hypothesis: The greater the consumption

Type 1 diabetes is an autoimmune disease that causes the insulin producing beta cells in the pancreas to be destroyed‚ preventing the body from being able to produce enough insulin to adequately regulate blood glucose levels. Type 1 diabetes may sometimes be referred to as juvenile diabetes‚ because it is commonly diagnosed in children and the condition can develop at any age. Insulin dependent diabetes is another term used to describe type 1 diabetes. Since type 1 diabetes causes the loss of insulin
