Human blood group systems

The human body is made up of trillions upon trillions of cells. Each cell has a nucleus, inside that nucleus are chromosomes. Each chromosome is made up of miniscule deoxyribonucleic acid (DNA) strands. Segments of that DNA code for hair color, eye color, height, body type, etc. In some cases, genes will mutate, thereby modifying the DNA code and resulting in a genetic disorder. A mutated gene can either be inherited or acquired in one’s lifetime. Genetic disorders are obtained one of two…

While the term cave man came around due to them finding bones in caves and assuming they lived in caves; studies from “Researchers from the Muséum National histories Naturelle in Paris said it suggests the early human ancestors settled in areas where they built structures to live for extended periods of time” (Buckland). These researchers have found evidence that Neanderthals hunted mammoths and used their bones to create circular houses. Neanderthals would wrap…

NE (Norepinephrine)Plays a role in mood disorders such as manic depression | Attentiveness, emotions, sleeping, dreaming, and learningReleased as hormone into blood | Excitatory (alpha1, beta1, beta2)Inhibitory (alpha2) | DA (Dopamine)The loss of dopamine in certain parts of the brain causes muscle rigidity typical of Parkinson’s disease | Controls movement and postureModulates moodCentral role in positive reinforcement…

antioxidant selenium it's no wonder that spinach helps lower risk of numerous health problems related to oxidative stress. Our blood vessels, for example, are especially susceptible to damage from oxidative stress, and intake of spinach has been associated with decreased risk of several blood vessel-related problems, including atherosclerosis and high blood pressure. (Interestingly, the blood pressure benefits of spinach may be related not only to its antioxidants, but also to some of its…

Identification of human carcinogen (DDT) DDT (dichloro-diphenyl-trichloroethane) is a pesticide derived from chlorinated hydrocarbon. DDT‘s history dates back to 1940’s, the use of this pesticide eventually peaked in the 1960’s. However due to its detrimental effects on human health and wildlife, it was banned from the United States market in 1972. DDT like other chlorinated hydrocarbon is a very stable compound and hence, tends to be more persistent in the environment. DDT is also known as a…

“assumption” that there is an interaction between the mind and body and is conducted by various components or the sensors of polygraph machine, which are attached to the body of the accused, who is interrogated by the expert. The machine records the blood pressure, pulse rate & respiration & muscle movements. Polygraph test is conducted in three phases (a) pre-test interview, (b) chart recording (c) Diagnosis. The examiner will prepare “Questionnaire” taking the criminal charges & statements…

1 .Introduction Skipping breakfast is common amongst teenagers. Researchers concur that breakfast is the most important meal of the day. Mahony et al.(2005). Breakfast provides important nutrients such as calcium, iron, protein, B group vitamins and fibre. The body needs these essential nutrients. Research shows that if these are absent at breakfast, they are less likely to be compensated for later in the day. Fruit and vegetables are good sources of vitamins and minerals. There is a tremendous…

thing they do is have it sent to the lab to have an autopsy (Owen #). When the body is older and only has left-over bones, the first thing the forensic anthropologist will do when they are looking at the skeleton is identify if they are human—this is because human bones look very similar to, and may be mistaken as animal bones. After the forensic anthropologists receive bones; they have to use what…

The system in South Africa has been hindered by years of colonialism, apartheid, and post-apartheid governance. During which times, discrimination, migrant issues, income inequality and extreme violence, are all attributed to the hurting health system. The current disparity in health services is attributed to the macroeconomic system that did nothing to redistribute the resources in order to provide benefits and care…

that lived around the area. Humans were able to evolve to have a larger resistance to malaria. Haldane suggested that having the genetic tendency for sickle-cell anemia or thalassemia would make the chance of being infected by malaria, rarer. He was correct. But another trait was responsible for protection against malaria, G6PD deficiency. The mutation allows for more resistance. The environment was changing, becoming more prone to mosquitoes and in turn, infecting humans with malaria. But the…
