6.6 A few final thoughts This final section has concentrated on the heart, the lungs and the blood – the body's cardio-respiratory system. We saw briefly how the body takes oxygen in through the lungs, and discussed the importance of this for athletes in various sports. To understand the role of oxygen in the body and its importance to athletes, we had to draw on information that we had discussed in earlier sections about the way oxygen is carried in the blood and the way that the heart pumps blood to different par

4.1 Introduction The heart is the engine of the human body – but what about it's specific function in athletes participating in sport? We have seen that athletes need to get oxygen and nutrients to different parts of their body quickly – this means they need an efficient cardiovascular system, this means having an efficient heart. What do we mean by an efficient heart? We mean one that pumps a lot of blood with every beat and that can beat quickly for a long period of time. An athlete's heart differ

PediNeuroLogic Exam: 18 Month Old: Normal: Fine Motor/Coordination - Beads in Cup
He is able to pick up small beads and place them in a small container with good fine motor control. By using both blocks and beads, one is testing increasing levels of difficulty of fine motor control and coordination. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.
Help needed - being able to ask for help in French when you car breaks down
Understanding the traffic regulations and asking for help when your car breaks down (in French).
Students are introduced to chemical engineering and learn about its many different applications. They are provided with a basic introduction to matter and its different properties and states. An associated hands-on activity gives students a chance to test their knowledge of the states of matter and how to make observations using their five senses: touch, smell, sound, sight and taste.
"Biomedical Information Technology, Fall 2008"
" This course teaches the design of contemporary information systems for biological and medical data. Examples are chosen from biology and medicine to illustrate complete life cycle information systems, beginning with data acquisition, following to data storage and finally to retrieval and analysis. Design of appropriate databases, client-server strategies, data interchange protocols, and computational modeling architectures. Students are expected to have some familiarity with scientific applica
Introduction to portfolios and their uses
To identify what a portfolio is, why they are used and to identify some pieces of material that may be used to support claims for learning and development.
Postural and Kinetic Tremor - Reflexes Exam - Superficial Sub-exam - Patient 8
This 37-year-old left-handed white male has had tremors beginning in childhood, before he started school. Over the years, the tremors have slowly progressed in both upper extremities. Tremors have spread to affect the right leg. They are more pronounced in the left. Most of the time tremors are increased with anxiety and activity, but are also present at rest. There are no tremors in his feet. Because of the tremors, the patient cannot write, feed himself, use utensils, or even hold a cup. He c
This patient education program reviews the anatomy, symptoms, and treatments for arterial occlusive diseases, including the benefits and risks of aorto-bifemoral bypass surgery. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Physical activity and health
This RLO outlines the importance physical and mental health benefits to the individual of physical exercise. The second RLO in this series describes practical measures to build exercise into your daily routine. Part of the PAVE (Physical Activity Virtual Education) project.
Save the Oysters - Introducing Non-native Species to the Chesapeake Bay
Since the introduction of MSX and Dermo in the 1950’s, two infectious diseases that played a large role in the decline the Chesapeake Bay’s oyster population, several oyster hatcheries along the Eastern seaboard are working with scientists across many fields to develop innovative restoration programs. One idea is to introduce a non-native oyster from China called Crassostrea ariakensis. In this video podcast, MicrobeWorld talks about current research underway with C. ariakensis, the potentia
Lunar Rotation and Flyby from Clementine Data
Clementine was a joint project between the Strategic Defense Initiative Organization and NASA. The objective of the mission was to test sensors and spacecraft components under extended exposure to the space environment and to make scientific observations of the Moon and the near-Earth asteroid 1620 Geographos. Clementine was launched on 25 January 1994 at 16:34 UTC (12:34 PM EDT) from Vandenberg AFB aboard a Titan IIG rocket. After two Earth flybys, lunar insertion was achieved on February 21. L

Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar
