Course Overview:
  • Anatomy and Physiology Background DETAILS:
    • Anatomy and Physiology is the major core biology course around which the Academy of Medical Science Technology (AMST) student focuses his or her studies at Bergen County Academies (BCA).  This course provides a thorough background in anatomy and physiology at an introductory college level.  
    • Details of the curriculum and assessments for A&P Trimester 3 may be found by scrolling down. In addition, Trimester 1 and 2 information may be assessed as well via the course SiteMAP.
  • Anatomy and Physiology  TRIMESTER 3 CURRICULUM:
    • In trimester 3 we complete our study of cellular physiology as we consider how molecules move through membranes.  Essential to our future explorations of whole body physiology, we need to understand how molecules gain entry or exit from cells using diffusion, active transport or the large scale processes of endo- and exocytosis.
    • Whole body physiology begins with the question: "Why do many of the organ systems such as the circulatory, respiratory, digestive, and excretory systems exist?"  The answer deals with the need to provide a constant environment around our cells so that their physiology can continue which enables them to do their job.
    • Our FIRST whole body topic, entitled HOMEOSTASIS, deals with the process by which our bodies actually maintain a constant internal environment.
      • Homeostasis is created via Homeostatic Control Systems which are also called Negative Feedback Systems or Stimulus - Response Systems. If you understand the principles of control theory as it applies to human physiology you will then find it much easier to understand the answers to the WHY of anatomy and physiology.  This concept will be further elaborated during trimester 3 when the circulatory, respiratory, gastrointestinal, and urinary systems are explored in depth.
      • Control systems act to keep a controlled variable near its normal or set point value.  In other words, if a variable increases in value above the normal value, then the system acts in a way to reduce the variable back toward the normal value.  Thus a controlled variable will oscillate around its set point value.  The principles of control theory in humans applies also in general to engineering systems.  For example, thermoregulation in humans and termperature regulation in your house have similar components and operation. There are several crucial components to a control system which can be more easily understood by examing a specific example of blood pressure homeostasis:
        • STIMULUS: change in value of perceived variable away from its normal value
        • PERCEIVED VARIABLE: blood pressure
        • SENSOR: pressure receptors in the large blood vessels
        • AFFERENT PATHWAY: IXth and Xth cranial nerves carry information from the sensor to the integrating center
        • INTEGRATING CENTER: brainstem cardiovascular center where the perceived blood pressure is compared to the normal value
        • EFFERENT PATHWAY: sympathetic and parasympathetic autonomic nervous system nerves carry a decision made in the integrating center out to apparati that will put the decision into effect
        • EFFECTOR: smooth muscle wrapped around arteriole blood vessels 
        • RESPONSE: change in blood pressure in opposite direction from the normal value in comparison to the stimulus
    • It should be noted that control systems in the human body use both the nervous and endocrine systems.  The remainder of trimester 3 will be spent investigating  Communication Systems such as the
      • nervous systems and
      • endocrine (hormones).
      • Indeed, the interplay between the nervous and endocrine systems is so intertwined that they are often referred to as the Neuroendocrine system.
    • Therefore, trimester 3's major focus will be the beginning of an in-depth study of NEUROSCIENCE (the study of the nervous system) including sensors, sensory pathways to the brain, the brain, neural pathways to response tissues, and the response tissues: muscles and glands.  This study is the essence of the remainder of A&P I and.... all of A&P II during 12th grade.
      • To be specific, the first step of Neuroscience is to understand the anatomy and physiology of neurons which are the basic functional units of the human nervous system.  This study will take us into the study of electrophysiology as we learn the ionic events used by neurons to communicate with each other as well as sensors (e.g., retinal rods and cones) and effectors (e.g., muscles and glands.)


  • Anatomy and Physiology  INSTRUCTOR:
    • Dr. DeWitt was formally educated at the Univeristy of Michigan where he was awarded a PhD in the area of cardiovascular physiology.  He is a former Professor in the Department of Chemistry and Chemical Engineering at Stevens Institute of Technology. He has taught physiology concepts to various students ranging from high school to collegiate undergraduate, nursing, medical, and graduate students since 1973. Dr. D. is the first biology instructor at Bergen County Academies and was instrumental in the creation of the science curriculum in AAST and AEDT.  He currently teaches core courses for AEDT, AMST and GLE. He also teaches a number of electives in biology and physiology. All of his courses may be accessed at Dr. DeWitt's Websites Index.

ONE End-of-Program Exam (EPE) (15%)

Because we belong to the NJ Vocational High School System, all programs are required to evaluate the overall impact of each program on its students. Classically, an exam has been given to students in May of their senior year.  As you can imagine, inducing seniors to prepare for this exam, after they have completed 11 trimesters of work at BCA and have finally been accepted to a college or university, has been difficult.  Motivation is the key word in this process and so this year we are beginning a different approach in AMST with the assumption that at the end of 11th grade, each AMST student has completed all of their academy-specific coursework. 

The other problem has been that previous exams made the assumption that material learned in 9th or 10th grade will be easily recalled during May of the senior year.  So this year, the EPE will become part of the A&P I course, and will count for 15% of trimester 3's final grade and therefore about 5% of the final course grade.

During trimester 3, we will collaboratively work on the creation of a study guide to help students prepare for this exam.  Each section (1 & 2) of students will be divided into teams. These groups will work on determining what is a reasonable expectation of the content and level of detail that should be included on the exam and therefore the study guide.  They will NOT write the exam questions. 

The format of the exam needs to be one such that it can be graded quickly so Scantron forms will be used.  Therefore, no essays or short answer questions will be included.  Other formats are up for discussion.
