This feature from the NOVA "Cut to the Heart" Web site highlights facts about the heart -- including its size and placement -- and will help you to understand the importance of this wondrous organ in our bodies.

Recommended for: Grades 6-8

Mechanical forces play a decisive role during development of tissues and organs, during remodeling following injury as well as in normal function. A stress field influences cell function primarily through deformation of the extracellular matrix to which cells are attached. Deformed cells express different biosynthetic activity relative to undeformed cells. The unit cell process paradigm combined with topics in connective tissue mechanics form the basis for discussions of several topics from cell biology, physiology, and medicine.

How does a regenerating animal "know" what's missing? How are stem cells or differentiated cells used to create new tissues during regeneration? In this class we will take a comparative approach to explore this fascinating problem by critically examining classic and modern scientific literature about the developmental and molecular biology of regeneration. We will learn about conserved developmental pathways that are necessary for regeneration, and we will discuss the relevance of these findings for regenerative medicine. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

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.

A short introduction to the musical instruments that are played using a keyboard.

Students learn the function of the liver and how biomedical engineers can use liver regeneration to help people. Students test the effects of toxic chemicals on a beef liver by adding hydrogen peroxide to various liver and salt solutions. They observe, record and graph their results.

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.
