Course Content Summary Course Prefix and Number -- Course Title NAS 161- 162: Health Science I – II (4 cr.) (4 cr.) VCCS Course Description Presents an integrated approach to human anatomy and physiology, microbiology and pathology. Includes chemistry and physics as related to health sciences. Lecture 3 hours per week. Recitation and laboratory are 3 hours each per week. Total 6 hours per week. Part I of II. Part II of II. General Course Purpose NAS 161-162 is a college transfer-level course designed to meet the needs of students pursuing programs in various health technology fields. The course consists of formal lectures, demonstrations and laboratory activities, which examine the microscopic and gross anatomy of the systems of the human body and their physiology. Microbiology and pathology are integrated and emphasis throughout is on integrated operation of the body systems. This course is a requirement of many of the health technology curricula and may be completed prior to entry into the curriculum of choice. Course Prerequisites NAS 161 Prerequisite: ENG 111 eligible NAS 162 Prerequisite: NAS 161 Course Outcomes Upon completion of NAS 161, students will: Complete research projects using scientific writing and speaking. Describe the process of self-restoration of the body via homeostasis. Analyze and define medical terms relevant to each body system. Apply descriptive anatomical and directional terminology to the human body. Classify the major chemical components of organisms according to their structure and function. Describe the basic structure and function of the cell and its components, to include cellular transport, the cell cycle, protein synthesis and genetics. Identify primary tissue classes, their functions, and representative locations in the human body. Departmental Approval: Spring 2014 Visually identify specific examples of each tissue type. Describe the structure and function of human skin as well as common skin disorders. Visually identify histological features of human skin. Visually identify histological features of compact bone tissue. Describe the physiology of bone tissue, including the process of bone development and bone growth as well as some common bone disorders. Visually identify the bones in the human skeleton as well as selected bone markings and their functions. Describe types, classifications, and movements of synovial joints. Distinguish among characteristics of the three muscle tissue types in addition to the describing the microanatomy and behavior of skeletal muscles. Explain the naming criteria for muscles and visually identify selected muscles and their actions. Distinguish between the major anatomical subdivisions of the nervous system. Identify the histological structure and function of nervous tissue, to include electrophysiology. Describe the physiology of the brain and cranial nerves, spinal cord and spinal nerves, autonomic nervous system, and the senses. Visually identify selected anatomy of the brain, cranial nerves, spinal cord, spinal nerves, eye, ear, and tongue. Describe the germ theory of disease. Identify the primary groups of microbes, describe their structure and arrangement, and give examples for each group. Demonstrate the use of sterile technique and simple stain procedure Upon completion of NAS 162 students will: Complete research projects using scientific writing and speaking. Identify major endocrine organs, their secretions, and the effects of the hormones that are secreted. Identify the microanatomy and gross anatomy of the circulatory system, to include the blood, heart, and major blood vessels. Describe physiological functions of organs of the circulatory system, including blood production, typing and clotting; the cardiac cycle, regulation of cardiac output, systemic blood pressure, blood flow, perfusion and capillary exchange. Identify the parts of the cardiac conduction system, describe their functions, and relate the activity of the conduction system to ECGs. Analyze systemic blood pressure and calculate mean arterial pressure. Identify microanatomy and gross anatomy of the respiratory system. Describe physiological processes of the respiratory system, including the process of ventilation, analysis and calculation of respiratory capacities and volumes, and the mechanisms of external and internal respiration. Discuss the role of the respiratory system in acid-base balance. Identify microanatomy and gross anatomy of the urinary system. Describe the physiological functions of the kidney, to include blood flow through the kidney, urine production by the nephron, and blood pressure homeostasis. Assess the properties of urine via urinalysis and describe the micturition reflex. Discuss the mechanisms involved in fluid, electrolyte, and acid-base balance in the human body. Departmental Approval: Spring 2014 Identify microanatomy and gross anatomy of the digestive system. Describe physiological processes of the digestive system, including the processes of mechanical and chemical digestion, swallowing and nutrient absorption as well as the roles of enzymes and hormones involved. Describe the metabolic processes used to produce energy for the body, to include glycolysis, the Kreb cycle and the electron transport chain. Describe the mechanisms used by the body to regulate blood glucose levels. Compare and contrast the metabolic activities that occur during the absorptive and postabsorptive states. Describe the roles of carbohydrates, lipids, proteins, vitamins and minerals in proper nutrition. Identify microanatomy and gross anatomy of the male and female reproductive systems. Describe the physiological functions and hormone regulation of the reproductive system, to include gamete formation, follicle development and ovulation, and human development Describe the pathogenicity and control of microbes.
