BTEC BIOLOGY ASSIGNMENT 3 TASK 1 HOMEOSTASIS Homeostasis can be defined as a point of balance or internal equilibrium that all kind of system both living and non-living can work to keep themselves in this state of balance. Mechanisms of homeostasis in human body Temperature Regulation: If your body too hot or cold‚ there are several ways in which your temperature can be controlled. They involve sweating‚ shivering‚ capillaries and hairs. As we learn in the class when your body becomes; Too

Autonomic nervous system The autonomic nervous system (ANS or visceral nervous system) is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness‚ and controls visceral functions. The ANS affects heart rate‚ digestion‚ respiration rate‚ salivation‚ perspiration‚ diameter of the pupils‚ micturition (urination)‚ and sexual arousal. Whereas most of its actions are involuntary‚ some‚ such as breathing‚ work in tandem with the conscious

Hormones‚ Heredity‚ and Human Behavior July 14‚ 2011 BEH 225 Why do people behave the way they do? What makes us tick? While our environment molds some of who we are‚ much more comes from heredity and hormones. Genes passed on to us from our parents make up heredity‚ and glands throughout the body produce hormones. As generations progress‚ new psychological and behavioral traits are earned and learned. This paper will explain hormones and the endocrine system‚ glands associated with the endocrine

Chapter 8.1 1. List the four biological levels of organization in a human in order from most simple to most complex. Cells‚ tissues‚ organs‚ organ systems 2. Define the term “homeostasis”. The tendency of the body to maintain a relatively constant internal environment. 3. What does the term “feedback system” refer to with respect to homeostasis? A cycle of events in which a variable‚ such as body temperature‚ is continually monitored‚ assessed‚ and adjusted. 4. List the three components

The kidney is a major site for the inactivation of the drug. This applies mainly to peptides like insulin‚ glucagon‚ PTH‚ and imipenem. 4. There is a significant drop in the binding of the drug to plasma proteins. For instance‚ a decrease in the protein binding from 99 to 95% results in a fourfold rise in the unbound‚ active drug concentration. Dose adjustment

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical

liver. This small organ that belongs to both the digestive system to the endocrine system; the pancreas‚ in fact‚ is very important for the secretion of enzymes that help digest complex carbohydrates and lipids; also it produces the hormones insulin and glucagon‚ which regulate the level of glucose in the blood. Pancreatitis‚ which is the inflammation of the pancreas‚ may be due to various causes. The most common is represented by diseases of the biliary tract‚ particularly from gallstones and liver

Ever wonder why the body shivers when it gets cold? Homeostasis keeps body conditions steady and constant. So‚ this means that when the body shivers‚ that is homeostasis taking place trying to keep your body temperature at a constant degree. Homeostasis maintains normality in the body in many different ways. Some examples include osmoregulation‚ thermoregulation‚ chemical regulation‚ and behavioral homeostasis. While homeostasis controls these processes‚ homeostasis must also go through a separate
