3.1.1 Blood Detectives - Conclusion Questions
You fall down and scrape your hand – describe what each component of blood would be doing at the injury site.
At the injury site, each component of blood would be doing various jobs. For example, both the plasma and the platelets would assist to clot the blood, thus a person would not bleed out. Furthermore, the white blood cells would aid in prevention of injection. In addition, the red blood cells would help to deliver oxygen to the injury site.
Anna has a condition called sickle cell anemia, a blood disorder. Based on the differences you observed between the normal blood slide and Anna’s blood slide, what do you think is a defining feature of this disease? Explain your answer.
A defining feature of this disease would be the sickle-shaped cells that …show more content…
The abnormal shape of a sickled red blood cell affects it movement through blood vessels because, the sickled red blood cells appear like a crescent moon, which do not move easily through the blood vessels, causing the red blood cells to become stuck and then accumulate in the blood stream. This causes clotting, as well as pain and other complications.
People with sickle cell anemia often experience episodes of severe pain in their joints, chest, and abdomen and swelling in their hands and feet. Using what you know about the function of blood, why do you think the abnormal shape of sickled red blood cells causes these symptoms?
The abnormal shape of sickled red blood cells causes these symptoms because the shape of the sickle cells causes blood cells to get caught, and therefore hinder the movement of the blood cells through the bloodstream. The pain occurs because the cells are forced into blood vessels and are pushed onto the blood vessels
Anna’s autopsy shows that the nails on her fingers were a blue/gray color. How does Anna’s hematocrit level relate to these

...1 1 Nature of the interface Biosensor, in essence, is a device that detects and measures electric impulses in biological elements such as skin, muscle or brains. Biosensors can also be used to detect certain biological analytes or in other words, components, from chemical substances. This could be the concentration of a distinct conductive element in the blood flow of a person for example or a toxin in a food product. The use of biosensors provides a multitude of different inputs for a user interface. Biosensors themselves are rather inadequate in order to be used as the sole way to control a user interface. Instead they can be used to enhance the user experience and widen the range of input methods used in an interface. For example the use of biosensors enables a system to respond to the user’s heartbeat rate and muscle tension or to identify the position and movement of body parts such as fingers. Currently, existing biosensors measure physiological activity, muscle electrical activity, brain electrical activity, and eye movement among other things. Extracting accurate physiological data from biosensors is often a complex task. In particular, extracting data from different typologies of biosensors will require architecture of great flexibility and the possibility to connect them to different external monitoring devices. Biosensors are key components in both physiological and psychophysiological computing. Psychophysiological computing can be considered to be the same as...

Widespread effort to use the minimum amount of energy for maximum mechanical functioning is the aim of product developers and consumers – a fortunate trend since advances and personal effort in this field are essential for everyone’s well-being.

ENERGY STAR evaluates a wide variety of products including appliances, electronics, and construction equipment. Those in search for new appliances are well-advised to consult the ENERGY STAR list of approved products beforehand! [1] In addition to keeping an eye out for the best products, it benefits the individual to know what makes a product energy efficient, mechanically speaking, and how they can maintain their appliances to function optimally while using as little energy as possible. This is beneficial not only for the environment, but also for one’s electric bills. Refrigerators ...

Police Officers

...1 Occupational Health and Safety Issues of Police Officers in Canada, the United States and Europe: A Review Essay © Jennifer R. L. Parsons June, 2004 2 Introduction Police officers play a pivotal role in North American and European societies. They are involved in many aspects of North American and European life. Officers’ involvement ranges from general, daily, proactive patrol activities to specific criminal activities such as narcotic investigations. Because there is such a wide range of activities involved in police work, there are many health and safety issues surrounding policing as an occupation. Police officers may be exposed to different health and safety risks in their occupation. For example, police officers are at risk of assault and homicide; the dynamics of policing as an occupation creates opportunities for them to experience many psychosocial hazards such as stress, suicide, sexual harassment, and discrimination. It is important that research be completed on the health and safety issues of police officers in order to identify hazards and identify ways to reduce risk. The failure to identify and solve health and safety concerns of officers has potentially serious consequences for the health and well being of officers and their families. These consequences can include depression, divorce, suicide, and disease. Not addressing the health and safety issues associated with policing may also impact the general public. For example, if an officer is...
