The field of positive psychology is a relatively new area of study and its research is in its infancy. According to Alex Linley‚ Joseph‚ Harrington‚ and Wood (2006)‚ positive psychology in a nutshell‚ is the creation of a common language‚ which translates the study of positive traits and outcomes. It is also a domain of psychological strengths with a common metaphysical heritage‚ which relates and interacts with each other (Alex Linley‚ Joseph‚ Harrington‚ & Wood‚ 2006).

THE DIGESTIVE SYSTEM OF CHICKEN In most livestock‚ teeth function to grind feed into smaller particles. Birds must pass feed usually whole into the esophagus because they do not have teeth. Therefore‚ particles of poultry feed should be small enough to pass through the esophagus. Feed passes from the mouth and through the precrop esophagus to the crop. If the proventriculus and gizzard are full‚ feed is stored in the crop. Feed is also moistened in the crop. Feed passes from the crop through the

of food. Saliva moistens the food while the teeth chew it up and make it easier to swallow. Amylase‚ which is the digestive enzyme‚ found in saliva‚ starts to break down starch into simpler sugars before the food even leave the mouth. The nervous pathway involved in salivary excretion requires stimulation of receptors in the mouth‚ sensory impulses to the brain stem and parasympathetic impulses to salivary glands. Swallowing his food happens when the muscles in his tongue and mouth move the food into

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

Enzyme Study Questions 1. Definitions/terminology: o enzyme: a protein molecule that catalyzes chemical reactions without itself being destroyed or altered o catalyst: a substance that increases the rate of a chemical reaction but is not consumed or changed by it. o substrate: a substance upon which the enzyme acts. o denaturation: the partial or total alteration of the structure of a protein without change in covalent structure by the action of certain

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

Florence Nightingale believed that unnecessary noise is the most cruel absence of care‚ which can be inflicted either on sick or on well (Choiniere‚ 2010). “Sleep is essential in healing”‚ is what we have been told since the second we walked through the door of nursing school. What we do not learn in school is the amount of noise that actually exists in the hospital and the negative effects it has on our patients. Hospital noise has negative effects on our patients and on us‚ healthcare workers.
