Biology: Colours present in the Human Body

  • Albanism

    Albinism is an inherited condition present at birth, characterized by a lack of pigment that normally gives color to theskin, hair, and eyes. Many types of albinism exist, all of which involve lack of pigment in varying degrees. The condition,which is found in all races, may be accompanied by eye problems and may lead to skin cancer later in life.

    Blue Baby Syndrome

    During transport in animals, that is while discussing circulation in animals, one of the topics usually asked about by students is if it is true that our skin may become blue! Mariah and Shanice researched this query and prepared the following:

     

    All the colours in the Human Body

    Which colours are present in the human body? One assignement given to my Biology students was to research the occurance of colour in our body.  Is the human body a colourful one? Take a look at the following presentation, and judge for yourselves!

    The Blue Baby Syndrome Sometimes the blue baby syndrome may begin when large amounts of nitrates in water are ingested by an infant and converted to nitrite by the digestive system. The nitrite then reacts with oxyhemoglobin (the oxygen-carrying blood protein) to form metheglobin, which cannot carry oxygen. If a large enough amount of metheglobin is formed in the blood, body tissues may be deprived of oxygen, causing the infant to develop a blue coloration of their mucous membranes and possibly digestive and respiratory problems. This condition is also known as methemoglobinemia. All the above was researched by Shania Duca & Mariah Mallia

     

    DNA Molecule: The Blue Print of Life

     

    Every living organism depends upon its proteins for its existence. In many organisms proteins form the very structure of the living creature, but even in plants -- where the structures are built more from sugars -- proteins perform the functions that allow an organism to live. Each type of organism, and each organ within a complex organism, is defined by the proteins of which it is composed. So whatever organizes the proteins in a living being is providing the blueprint for building that organism. DNA does just that: it provides the information for building all the proteins within every living thing on Earth.
