Using the stethoscope to check blood pressure is a technique thatŐs been used for >100 years! Blood pressure is one of the major vital signs frequently measured by health care workers, and it tells us a lot about our blood circulation. Learn what blood pressure is, how it relates to resistance in a tube, why it is necessary to get oxygen to your cells, and how it can change as you age. WeŐll finally put it all together by relating pressure, flow, and resistance in one awesome equation!

The human body enjoys stability. For example, if your blood pressure changes, the body puts a couple of brilliant systems into motion in order to respond and bring your blood pressure back to normal. There are some quick responses using nerves and some slower responses using hormones. The system using hormones is sometimes called the renin-angiotensin-aldosterone-system (RAAS), which is the main system in the body for controlling blood pressure. When your blood pressure drops too low or gets too high, your kidneys, liver, and pituitary gland (part of your brain) talk to each other to solve the problem. They do this without you even noticing! Learn how the body knows when the blood pressure has changed, and how hormones like angiotensin 2, aldosterone, and ADH help return blood pressure to back to normal.

This electronic textbook covers histology and embryology of the head and neck for students in a Dental hygiene program.
It contains numerous hyperlinks, animated images and interactive quizzes.

Students further their understanding of the engineering design process while combining mechanical engineering and bioengineering to create an automated medical device. During the activity, students are given a fictional client statement and are required to follow the steps of the design process to create medical devices that help reduce the workload for hospital workers and increase the quality of patient care.

Students learn the purpose of a fever in the body's immune system and how it protects the body against germs. The students continue to explore temperature by creating a model thermometer and completing a temperature conversion worksheet. They come to see how engineers are involved in designing helpful medical instruments such as thermometers.

Students continue the research begun in the associated lesson as if they were biomedical engineers working for a pharmaceutical company. Groups each perform a simple chemical reaction (to precipitate solid calcium out of solution) to observe what may occur when Osteopontin levels drop in the body. With this additional research, students determine potential health complications that might arise from a new drug that could reduce inflammatory pain in many patients, improving their quality of life. The goal of this activity is to illustrate biomedical engineering as medical problem solving, as well as emphasize the importance of maintaining normal body chemistry.

Acting as if they are biomedical engineers, students design and print 3D prototypes of pressure sensors that measure the pressure of the eyes of people diagnosed with glaucoma. After completing the tasks within the associated lesson, students conduct research on pressure gauges, apply their understanding of radio-frequency identification (RFID) technology and its components, iterate their designs to make improvements, and use 3D software to design and print 3D prototypes. After successful 3D printing, teams present their models to their peers. If a 3D printer is not available, use alternate fabrication materials such as modeling clay, or end the activity once the designs are complete.

Students learn about how biomedical engineers create assistive devices for persons with fine motor skill disabilities. They learn about types of forces, balanced and unbalanced forces, and the relationship between form and function, as well as the structure of the hand. They do this by designing, building and testing their own hand "gripper" prototypes that are able to grasp and lift a 200 ml cup of sand.

Student teams build model hand dynamometers used to measure grip strengths of people recovering from sports injuries. They use their models to measure how much force their classmates muscles are capable of producing, and analyze the data to determine factors that influence a person's grip strength. They use this information to produce a recommendation of a hand dynamometer design for a medical office specializing in physical therapy. They also consider the many other ways grip strength data is used by engineers to design everyday products.

The Medical Assisting program prepares the student for employment in physician's offices and clinics. Medical Assistants help physicians by doing tasks to assist in the treatment and examination of the patient. They provide for the efficient operation of a doctor's office and some may specialize in the back office, while others may choose to work in the front office.The Medical Assisting Core provides information and skills common to all medical assistants. The student gains essential competencies and accumulates a body of knowledge that provides a foundation for movement into the administrative or clinical segments of the program. Course content includes: career orientation, medical terminology, body structure and function, law and ethics, emergency care, communications and interpersonal skills, community resources, health, and job preparedness.The Medical Assisting Clinical segment provides the student with the technical knowledge required to work in the "back office". Course content includes medical/surgical asepsis, assisting with the physical examination, office surgery, electrocardiography, administration of medications, basic laboratory skills, assisting with diagnostic and therapeutic procedures, and specialized medical practice.

This competency-based core course is designed for all students seeking a career in the health care field. The course will focus on the concepts and principles of the structure, function and systems of the human body in relationship to human growth and development. Students will learn to recognize problem situations in health care settings as relate to direct and indirect patient care and they will demonstrate the use of critical and creative thinking skills and logical reasoning for problem resolution.Safety issues, ethical considerations, legal constraints and professional codes will be presented and discussed throughout the course. Students will use the knowledge of disease prevention for the maintenance of optimal health.Integrated throughout the course are career preparation standards, which include basic academic skills, communication, interpersonal skills, problem solving, workplace safety, technology, and employment literacy.

Students will discuss the special considerations that must be made when dealing with the human body, and will gain an appreciation for the amazing devices that have improved our quality of life. They will also explore how " čĎForm Fits Function'. This lesson should serve as a starting point for students to begin to ponder how the medical devices in their everyday lives actually work.

Melvin Herbert Evans is the Virgin Islands' first elected governor. Evans graduated from Howard University with a B.S. in 1940 and from the Howard College of Medicine with an M.D. four years later, following graduation from high school on St. Thomas. He then worked in a variety of medical and public health positions for the United States and the Virgin Islands.
