How Chemistry Is Related To The Forensics Of Blood

When people usually hear the word forensics they usually automatically visualize crime scenes filled with things that can vary from blood, bullets, fingerprints ect. Unfortunately, it is not as cut and dry as you think, you're only seeing a small piece of the picture. The subject of forensics itself is very broad and actually involves a variety of different sciences all mixed together including, biology, chemistry, genetics, toxicology, phonetics, medicine, engineering, anthropology and many more. It is one of the fields of law enforcement, were technology and crime-solving all come together as one. Gathering the information needed to figure out what happened and the methods used to connect pieces of evidence to the crime scene were also not

Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne

After further research I learned that a forensic scientist needs a degree in a natural science such as biology, chemistry, or in forensic science, or biochemistry. When applying to colleges most did not offer or have a major in biochemistry, but all had general chemistry and biology. Central State was a school that did not have biochemistry, but after further research I learned that there was something for me here. I learned that the school offered a major in chemistry, and after completion of the chemistry courses I could minor in forensic science. However, with a chemistry degree I would be qualified to work in any crime laboratory in the United States. Many undergraduates will get a degree in a natural science and go on to get a master’s in forensic

The general charactertics of blood are color, composition, and pH. The composition of blood is determined by collecting blood from a person then it’s placed in a centrifuge which shows plasma is 55% of whole blood and 45 % is erythrocytes. Another name for red blood cells is erythrocytes which are small sacs of blood that carry oxygen and

For this experiment student will identify the individual blood types through the antigen and antibody reaction by using the anti- A, Anti- B and Anti- Rh serums we will be able to identify the different types of blood. Red blood cells also known as erythrocyte are small cells shaped like an oval however they have a plasma membrane but no nucleus. Hemoglobin is the protein that allows the red blood cells to bind easily with oxygen. While hematopoiesis is known as blood cell formation. The independent variable would be the Red blood cells. While the dependent variable would be the Antibodies and the antigens

To name the two major components of blood and state their average percentages in whole blood.

Blood is a mixture of liquids and solids. Blood contains plasma, serum, red blood cells, white blood cells proteins and more. Blood does not stay in liquid form for a long time after being exposed from your body, due to clotting. It clots a few minutes forming a dark red, gel-like substance that becomes more solid time passes. Blood clots can tell an attack was prolonged or the victim was bleeding for a significant period after being injured.

There are different types of patterns that blood splatter makes. It can be a drop, a messy splatter, to just a little pool of blood it all just depends on what caused it to happen. Forensics and law enforcement officers can determine what kind of object was used in a murder case based on the blood splatter pattern.

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne

Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.

Forensic and DNA casework has been a major player in catching these cold blooded killers. Since most investigators have to work from clues, they rely on these sources to lead them in the right direction. Many findings such as, blood, weapons, hair, or any source of DNA can help put the puzzle pieces of these cases together. This has solved many cases, and is a strong piece of evidence in the judicial system.

Forensic Science is applying science to criminal law. Forensics uses science to support or shoot down theories made about a crime or the crime scene. Forensic science has many branches, such as forensic toxicology, forensic psychology, forensic entomology and more. There are so many fields to go into, and they are all necessary for the criminal justice process using forensic science. While forensics is a very broad field, all origins of it come from basic scientific study, such as general biology (What Is Forensics).

Forensic science borrows from a number of sciences which include: physics, Biology and chemistry. It therefore involves examination of a wide spectrum as compared to any other method of investigation. Due to the wide spectrum of investigation and evidence analysis the method offers; it ensures that the results are accurate and can be used in the court of law to make a decision. The method establishes the existence of a crime, the connection between the crimes and the

Blood chemistry or blood test is identifying the different levels of chemical ingredients found in the blood. The analysis of these substances provides clues to a patient’s condition and the functioning of the major body systems such as, blood sugar levels, liver functions, essential nutrients etc. This helps doctors in diagnosing the patient’s conditions much easier and quicker.
