of Group Members: Date: Introduction: In this lab‚ you will be examining many characteristics of a rat’s anatomy. Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially. The Classification of the Rat (Rattus norvegicus): Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Mammalia Order: Rodentia

Myelin is a spiral sheet of cell membrane wrapped around the axon. In the CNS‚ myelin is produced by oligodendroglial cells and in the PNS by Schwann cells. Each oligodendrocyte makes multiple segments of myelin that wrap

to take the fact that their lives will never be the same after this pandemic swept through‚ and then some considered this a new beginning‚ a way to start over fresh and change their lives around. To understand the Black Death a little more‚ one might need background information. The name “Black Death” is a recent name that was recently given to this horrible epidemic. The original names for the Black Death were “The Great Mortality” or “The Pestilence.” The name “The Black Death” came from a mistranslation

The urinary system is very vital in preventing buildup of waste in the body. It’s main function is to clean the blood and maintain healthy levels of acids and minerals in the blood. Each organ in the urinary system is responsible for completing their own job while working together to keep the body healthy. The kidneys “prevent the buildup of wastes and extra fluid in the body‚ keep levels of electrolytes stable‚ such as sodium‚ potassium‚ and phosphate‚ make hormones that help regulate

The digestive‚ respiratory and the cardiovascular system are all interrelated in order to make the human body work effectively and efficiently by working as an orchestra. The cardiovascular system and the respiratory will work together in order to perform the gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. This means oxygen (in) CO2 (out).

Function The urinary system helps maintain homeostasis by regulating water balance and by removing harmful substances from the blood. The blood is filtered by two kidneys‚ which produce urine‚ a fluid containing toxic substances and waste products. From each kidney‚ the urine flows through a tube‚ the ureter‚ to the urinary bladder‚ where it is stored until it is expelled from the body through another tube‚ the urethra. The kidneys are surrounded by three layers of tissue: The renal fascia is

He takes seriously‚ for example‚ the claims’of educational philosophers like William Hare and myself that there is a logical connection between Russell’s philosophy and his educational thought even though he goes on to reject this perspective. 2 Then‚ in defence of his own view‚ Hager provides a clear and cogent account of Russell’s philosophical method. and indicates the implications of this method for P I Russell‚ n.s. 13 (1993): 150-67.

* Difference in Somatic and Autonomic Nervous System * The somatic nervous system consists of nerves that provide VOLUNTARY control over skeletal muscles * The autonomic nervous system exerts INVOLUNTARY control over the contraction of smooth muscle‚ cardiac muscle‚ and glandular activity. * Basic function of the Sympathetic VS Parasympathetic Systems * Sympathetic system= “fight of flight” * Parasympathetic system= “rest and digest” * Both autonomic branches are required

The digestive system is a combination of organs which have been arranged together to help carry out its particular function of turning food into the energy which is necessary to survive and packaging the excess residue for waste disposal. Digestion involves the breakdown of food into smaller components. The process of digestion has many stages with the first starting in the oral cavity. Within the system‚ food passes through a tube called the alimentary canal‚ more commonly known as the gastrointestinal
