------------------------------------------------- Animal nutrition Introduction to animal nutrition There are seven major classes of nutrients: carbohydrates‚ fats‚ fiber‚ minerals‚ protein‚ vitamin‚ and water. These nutrient classes can be categorized as either macronutrients (needed in relatively large amounts) or micronutrients (needed in smaller quantities). The macronutrients are carbohydrates‚ fats‚ fiber‚ proteins‚ and water. The micronutrients are minerals and vitamins. The macronutrients

ACKGROUND Th e pancreas is an organ that possesses both endocrine and exocrine functions and is located in the upper right quadrant of the abdominal cavity. Th e endocrine function of the pancreas relates to the secretion of two hormones‚ insulin and glucagon‚ which serve to regulate the levels of blood glucose. Th e exocrine function of the pancreas involves the secretion of enzymes that are responsible for the digestion of food in the lumen of the small intestine. Normally‚ the digestive

ANATOMY AND PHYSIOLOGY OF THE DIGESTIVE SYSTEM The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that

stored potential energy in the human body because they store about twice the amount of energy than polysaccharides. Triglycerides are also major components in metabolism and insulation in the human body. When there is an increase in glucagon and a decrease in insulin levels in the blood‚ it triggers the release of the triglycerides from the adipose tissue. The triglycerides do not exit the tissue intact; they are hydrolyzed by an enzyme into a glycerol molecule and three fatty acids. These components

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to

The field of study dealing with the endocrine system and its disorders is endocrinology‚ a branch of internal medicine. The endocrine system is an umbrella term used to describe the complexity of different types of endocrine glands which are responsible to help the body carry out many of its functions. This system regulates our mood‚ growth‚ metabolism‚ tissue development‚ sexual functions and reproductive process. The endocrine system is made of a series of glands that produce chemicals

BIOLOGY SYNOPTIC ESSAY – UNIT 5 – JUNE 13 THE MEMBRANES OF DIFFERENT TYPES OF CELLS ARE INVOLVED IN MANY DIFFERENT FUNCTIONS – 25 MARKS Membranes are found in all organisms‚ around and within cells. They control the movements in and out of cells‚ as well as protecting cells. They also allow different functions to occur. They have the same basic structure called the plasma membrane. All plasma membranes‚ around or inside cells have a same phospholipid bilayer structure. Phospholipids contribute to
