Blood Composition. The following are components of blood - red blood cells‚ white blood cells‚ platelets and plasma (the liquid component). Red blood cells are the pinky white circles‚ the white blood cells are the big red blobs. Red blood cells do not have a nucleus because they do not divide and multiply Red blood cells are bi-concave‚ they are donut shaped. Red blood cells contain a pigment called haemoglobin which can react with oxygen to form the unstable compound‚ oxy-haemoglobin. Hb+4O2

Blood a journey through the body. You might find yourself asking‚ what does blood have to do with digestion‚ respiration and circulation? Hopefully‚ after the presentation all of your questions will be answered. When a person thinks of digestion they usually think about what happens in the stomach. A lot has happened to digest the food way before it gets to the stomach. It starts in the mouth or oral cavity. It is a process called mechanical digestion. First‚ Mastication begins. Mastication

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg

The aim of this experiment was to replicate the Primacy effect‚ which investigates the effects of ascending and descending performances on attributions of intellectual ability‚ illustrating that individuals’ perception of another individual is influenced by their first impression of that person to the detriment of all subsequent impressions. The design included independent groups‚ and the 46 participants over 16 years old (25 males and 21 females) were chosen through convenience sampling. The latter

Pooja Patel 08/19/2013 Documentary of Bad Blood: A Cautionary Tale Mrs. Jones MA 125 Through the eyes of survivors and family members and the producer Merlyn Ness‚ "Bad Blood: A Cautionary Tale" chronicles how a "miracle" treatment for hemophilia became an agent of death for 10‚000 Americans. Hemophilia is a rare genetic blood clotting disorder‚ most often passed from mother to son‚ resulting in severe crippling and often death. But in the 1960s‚ Judith Gram Pool dicoverd cryo precipitate from the

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then

Today I’m going to be speaking to you about the street gang known as the Bloods. I will be discussing the origin of the gang‚ some of the gang’s important members and the impact the gang has on the present day. It all began in 1971 when the gang that eventually came to establish the Bloods was created. The name of this gang was the Piru Street Boys and they were actually a set of the Crip gang‚ today’s biggest rivals of the Bloods. When the Piru Street Boys began their operations they were working

unethical experiments on human subjects; regardless of what their condition is or if they have been diagnosed with a disease. Although‚ the use of humans for experiments to further develop cures for diseases‚ or to improve weaponry in war has always been a questionable practice. Hundreds of medical experiments have been performed by various doctors such as: The Tuskegee Syphilis Study by the U.S Public Health Service‚ the experiments conducted in Nazi Germany by Josef Mengele‚ the experiments performed

The Elvis Experiment Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel. Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect
