Course Description

Surveys human body systems. Introduces structure and function of tissues, organs, organ systems and developmental changes over the lifespan. Covers basic chemistry and cell structure. Required prerequisite for Medical Assisting and Ophthalmic Medical Technology programs. Prerequisites: WR 115, RD 115 and MTH 20 or equivalent placement test scores. Audit available.

Addendum to Course Description

To clarify the teaching of evolution and its place in the classroom, the Portland Community College Biology Departments stand by the following statements about what is science and how the theory of evolution is the major organizing theory in the discipline of the biological sciences.

  • Science is a fundamentally non-dogmatic and self-correcting investigatory process. In science, a theory is neither a guess, dogma, nor myth. The theories developed through scientific investigation are not decided in advance, but can be and often are modified and revised through observation and experimentation.
  • The theory of evolution meets the criteria of a scientific theory. In contrast, creation "science" is neither self-examining nor investigatory. Creation "science" is not considered a legitimate science but a form of religious advocacy. This position is established by legal precedence (Webster v. New Lenox School District #122, 917 F. 2d 1004)

Biology instructors of Portland Community College will teach the theory of evolution not as absolute truth but as the most widely accepted scientific theory on the diversity of life. We, the Biology Subject Area curriculum Committee at Portland Community College, therefore stand with such organizations as the National Association of Biology Teachers in opposing the inclusion of psuedo-sciences in our science curricula.

Intended Outcomes for the course

Upon completion of the program students should be able to:

  1. Apply basic knowledge of general biology terminology, cell structure and function, histology, gross anatomy, and physiology related to the body systems to novel technical and/or clinical scenarios.
  2. Use an introductory understanding of how human organ systems are interrelated and change over the lifespan to apply a holistic approach to human health.
  3. Research and critically evaluate sources of information related to human organ systems in order to discern reliable scientific information from unsourced information and pseudo-science.
  4. At a fundamental level, communicate information related to human organ systems through written, verbal, or multimedia formats in order to assess current knowledge, answer investigative questions, and explore new questions for additional research.
  5. Evaluate the impacts of medical research and social and environmental inequities on health care disparity.

Aspirational Goals

Proceed through life with an increased appreciation and curiosity about the human body and an ability to apply scientific tools to lifelong learning and exploration. 

Course Activities and Design

This course will be taught in a traditional lecture and laboratory format. Lecture will be presented utilizing a variety of multimedia and interactive presentations. Additionally students will have reading assignments and will use case-studies and projects to practice application of their knowledge. Laboratory experiences will be combination of faculty lectures and guided  hands-on and team-based activities, utilizing a variety of resources including (but not limited to): multimedia, prepared microscope slides, human models, and animal specimens. 

Outcome Assessment Strategies

Assessments focused on the course content acquisition and application  (1 and 2) will be achieved using a some or all of the following: group projects and/or individual projects, quizzes, tests, in-class activities, case studies, laboratory activities, presentations, and journals. Formative feedback will be provided on these assessment. Lab quizzes and exams will be practical in nature and will require set-up and grading outside of lab time. The use of guided written projects and/or presentations will provide assessment of source evaluation and communication (3 and 4). Use of selected case-studies and projects will provide assessment opportunities for application and social context (3, 4 and 5)
