Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.

Following the steps of the iterative engineering design process, student teams use what they learned in the previous lessons and activity in this unit to research and choose materials for their model heart valves and test those materials to compare their properties to known properties of real heart valve tissues. Once testing is complete, they choose final materials and design and construct prototype valve models, then test them and evaluate their data. Based on their evaluations, students consider how they might redesign their models for improvement and then change some aspect of their models and retest—aiming to design optimal heart valve models as solutions to the unit's overarching design challenge. They conclude by presenting for client review, in both verbal and written portfolio/report formats, summaries and descriptions of their final products with supporting data.

As part of the engineering design process to create testable model heart valves, students learn about the forces at play in the human body to open and close aortic valves. They learn about blood flow forces, elasticity, stress, strain, valve structure and tissue properties, and Young's modulus, including laminar and oscillatory flow, stress vs. strain relationship and how to calculate Young's modulus. They complete some practice problems that use the equations learned in the lesson—mathematical functions that relate to the functioning of the human heart. With this understanding, students are ready for the associated activity, during which they research and test materials and incorporate the most suitable to design, build and test their own prototype model heart valves.

This course introduces the basic driving forces for electric current, fluid flow, and mass transport, plus their application to a variety of biological systems. Basic mathematical and engineering tools will be introduced, in the context of biology and physiology. Various electrokinetic phenomena are also considered as an example of coupled nature of chemical-electro-mechanical driving forces. Applications include transport in biological tissues and across membranes, manipulation of cells and biomolecules, and microfluidics.

Although a great deal of emphasis of the course is on the structures of the organs and tissues, this is not a course based solely on pure microscopic descriptions. Lectures and laboratory sessions will focus on the integration of structures with functions, drawing from many disciplines (light/electron microscopy, cell biology, biochemistry, physiology etc.). Highlights of the course are its magnificently detailed collections of tissues as represented in the Circulatory Lecture.

In this course, the student will study microscopic anatomy. The course begins with an overview of basic cell structure follow by an explanation of how single cells come together to make up tissues. The student will then study each of the organ systems in the body, understanding how these tissues fit together structurally to form organs and organ systems that carry out specific functions. Upon successful completion of this course, the student will be able to: differentiate among the types of microscopy and describe the importance of microscopes in microscopic anatomy; correctly use the compound light microscope with a working knowledge of the function of each part; identify the organelles within a eukaryotic cell and list the basic function of each; compare and contrast meiosis and mitosis, identifying the steps of each in microscopic images; outline what makes each epithelial, connective, nervous, and muscle tissue unique, where each is found within the body, and how each interacts with other tissue types; point out circulatory system features, including intercalated disks and valves, as well as the differences among different vessel types; identify the cells found in blood and the role of each; define how the tissues and anatomical features that make up the gastrointestinal and respiratory systems come together structurally to support the function of these organ systems; identify the features of the epidermis and dermis of the skin, including the cells, layers, glands, and other features of each layer; explain how the structural arrangement of the lymphatic system and lymph node supports its physiological role of filtering; compare and contrast the structural arrangement of spongy and compact bone; map out the path of plasma filtrate as it moves through the neuron and into the ureter, bladder, and urethra, identifying what types of cells are located in each part; describe the basic structure of endocrine organs, including the reproductive organs; identify what features make special senses tissue unique.

This courses focuses on the fundamentals of tissue and organ response to injury from a molecular and cellular perspective. There is a special emphasis on disease states that bridge infection, inflammation, immunity, and cancer. The systems approach to pathophysiology includes lectures, critical evaluation of recent scientific papers, and student projects and presentations. This term, we focus on hepatocellular carcinoma (HCC), chronic-active hepatitis, and hepatitis virus infections. In addition to lectures, students work in teams to critically evaluate and present primary scientific papers.

The video demonstrates the setting up of the isolated tissue/organ bath. It identifies the components of the equipment and describes the functions of each. This procedure also shows adjustments, suitable for related isolated tissue preparations.

How is it that all cells in our body have the same ...

How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or human body contain the same DNA, yet different cells in different tissues express, on the one hand, a set of common genes, and on the other, express another set of genes that vary depending on the type of tissue and the stage of development. In this video lesson, the student will be reminded that genes in a cell/tissue are expressed when certain conditions in the nucleus are met. Interestingly, the system utilized by the cell to ensure tissue specific gene expression is rather simple. Among other factors - all discussed fully in the lesson - the cells make use of a tiny scaffold known as the “Nuclear Matrix or Nucleo-Skeleton”. This video lesson spans 20 minutes and provides 5 exercises for students to work out in groups and in consultation with their classroom teacher. The entire duration of the video demonstration and exercises should take about 45-50 minutes, or equivalent to one classroom session. There are no supplies needed for students’ participation in the provided exercises. They will only need their notebooks and pens. However, the teacher may wish to emulate the demonstrations used in the video lesson by the presenter and in this case simple material can be used as those used in the video. These include play dough, pencils, rubber bands (to construct the nuclear matrix model), a tennis ball and 2-3 Meters worth of shoe laces. The students should be aware of basic information about DNA folding in the nucleus, DNA replication, gene transcription, translation and protein synthesis.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat. Learners will distinguish the nuclei of cell types and how nuclei differ between muscle cells and motor neurons. The lesson guide, part of NASA's "The Brain in Space: A Teacher's Guide with Activities for Neuroscience," includes background information, evaluation strategies, and activity sheets.
