  • Genetics - May 08, 2009 09:34 AM
    Genetics is a branch of biology that studies heredity and how certain characteristics or traits are passed from parents to offspring. The modern study of genetics began with the research of Gregor Mendel in the mid-1800s. His discoveries paved the way for today’s understanding of the role of genetics in human development and in the treatment of genetic disorders.

  • Science of the Body: Human Anatomy and Physiology - April 10, 2008 11:41 AM
    Gray’s Anatomy has long been considered the gold standard for human anatomy, and its size (1,400 pages) gives a sense of just how complex the human body is. Now, however, the majority of the information in Gray’s Anatomy can be found on the Web. The Science of the Body Web Guide points you to the Web’s best resources for each system of the body, no matter your level of expertise.

    The cardiovascular system is comprised of the heart, blood and blood vessels. Sounds simple enough, but it’s one of the most important systems of the body. Visit the findingDulcinea Cardiovascular System Web Guide for Web sites you’ll find useful regardless of your level of knowledge.

    The circulatory system includes the organs and tissues involved in circulating blood and lymph through the body, and it plays an important role in delivering nutrients to our cells and removing waste products. The findingDulcinea Circulatory System Web Guide gives you a selection of the best sites for information in a wide range of complexity.

    The digestive system comprises a system of organs that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. It incorporates the excretory and urinary systems, responsible for discharging waste from the body. The findingDulcinea Digestive System Web Guide provides the “ins and outs” of the digestive, urinary and excretory systems no matter what your level of expertise.

    The endocrine system is comprised of many small organs that are responsible for the release of hormones. It regulates metabolism, growth and development, tissue function and mood. Read the findingDulcinea Endocrine System Web Guide for a selection of the best Web sites for all levels of knowledge and need.

    Human anatomy is the study of the biological systems of the body, which consist of organs, tissues and cells. Parents and teachers looking for teaching aids, college students doing research for a term paper, and medical students and professionals searching for references on complex anatomical structures will all find appropriate Web sites in the findingDulcinea Human Anatomy Web Guide.

    The integumentary system is the external covering of the body, including skin, hair, nails, sweat glands and their products (sweat and mucus). It is responsible for excreting wastes and regulating temperature, and is the location of sensory receptors for pain, pressure and temperature. Use the findingDulcinea Integumentary System Web Guide to find Web sites on the integumentary system.

    The lymphatic system, which includes lymph nodes, ducts, capillaries, vessels and tissues, is responsible for the removal of excess fluids from body tissues and for the production of immune cells. Working in conjunction with the lymphatic system is the immune system, a collection of mechanisms within the body that protects against disease by identifying and killing pathogens and tumor cells. Use the findingDulcinea Lymphatic and Immune Systems Web Guide to find information about the lymphatic and the immune system.

    The muscular system, which includes skeletal, smooth and cardiac muscles, is controlled by the nervous system (except, of course, for the cardiac muscle that functions involuntarily) and is responsible for movement. Consisting of 206 bones as well as joints, cartilage and ligaments, the skeletal system provides the strong, internal framework that supports our body. The findingDulcinea Muscular and Skeletal System Web Guide spotlights a selection of Web sites on the muscular and skeletal systems.

    The human nervous system is the control center of the body, monitoring conditions within and outside the body and sending out electrical impulses to respond to them. No matter what your level of scientific aptitude, you’re sure to find interesting information on the sites in the findingDulcinea Nervous System Web Guide.

    The reproductive system includes the organs that work together for the purpose of reproduction. The system is composed of external and internal organs as well as fluids, hormones and pheromones. Whether you’re a professor, a physician or someone who’s simply searching for basic information, you’ll find plenty of helpful sites in the findingDulcinea Reproductive System Web Guide.

    The respiratory system consists of the airways, the lungs and the respiratory muscles that mediate the movement of air into and out of the body. Visit the findingDulcinea Respiratory System Web Guide for a selection of Web sites on the respiratory system.
