Name and discuss six functions of the integumentary system. * Protection- chemical (low pH secretions & bacterial activity), physical/mechanical (keratin &glycolipids block most water & water soluble substances), biological barriers (dendritic cells, macrophages & DNA). * Body temperature regulation- helps keep body temperature at a normal level. * Cutaneous sensations- sense touch, pain, and temperature. * Metabolic functions- synthesis of Vitamin D, chemical conversion of…

P5 List of all cell features and functions: • Nucleus • Cytoplasm • Cell membrane • Mitochondria • Ribosomes • Cell wall (Plant Cell) • Endoplasmic Reticulum (smooth & rough) • Lysosome • Golgi Apparatus/body • Nucleolus • Vesicles A nucleus is like the brain of the cell, it is a large oval which controls the activities of the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information. Most chemical processes and reactions, which are…

A genetically altered baby is something some people have only dreamed about, but now, it has become a reality. Scientist have discovered a way to alter human genetic traits and produce the perfect offspring. Some traits scientists have tried to alter include sex, eye color, and height, but it is still in the experimenting stage and should be possible within the next few years. Add more. Creating genetically altered babies should be prohibited. Genetically altering babies is still in the…

Eubacteria best live in moderate temperatures, low salts and where there is a plethora of sunlight or organic compounds (Ladiges, 2010). The main differentiating structure of eubacteria is that it has peptidoglycan in its cell walls, has one RNA polymerase and has the ability to form spores that can live many years but remain inactive until its environment is just right for it to activate itself. They are similar to eukaryotes in that they also have ester linked lipids,…

Most importantly, we have tools like stem cells to help science advance many medical researches that could lead to break through in medicine. I know that anti-abortion groups will want us to believe that abortion is wrong and evil, we should disregard their arguments because they are solely based…

many other problems with the lung, pancreas, and many other parts in your body. The disease is caused by a defective gene called the CFTR gene. These genes code to produce CFTR proteins which are used to transport water and particles into or out of cells. This helps maintain a healthy balance of water and salt in your body. However in people with Cystic Fibrosis, these genes cannot properly code proteins, causing very thick mucus. This can cause blockage in the lungs and digestive system. Cystic…

Introduction Designer babies used to be something that was only in science fiction books, but now, scientists are very close to being able to create them. There are many unknowns with designer babies such as will they be used to create healthier babies only, or will everything be about making the “perfect” looking baby. That is just one example of many. However, what could possibly be one of the most harmful consequences of designer babies is a reduced gene pool that could be caused by the…

Movement of cells are important since some cells depends on movement to carry out its major function. For example, sperm cells need to move from one place to another place to carry out reproduction. Movement of cells are supported by cytoskeleton system of the cells. The cyctoskeleton system are composed of microtubules, microfilaments and intermediate filaments. However, for unicellular organisms such as Paramecium, the movement of cells are regulated through cilia or flagella. Cilia can be…

A genetic research advancement enables genetic counselors to obtain information on the specific genes of an embryo. Currently, a test can reveal whether several life-threatening diseases or disabilities, such as Tay-Sachs or Autism, are prevalent in an embryo. As research continues to progress, scientists perceive it will be possible to test for non-disease genes such as intelligence, violence, or memory capability. Therefore, as many couples utilize in vitro fertilization (IVF) to reproduce,…

CONCEPT 2: THE CONCEPT OF HOLISM IN NURSING CARE This concept is taken from Block 5, Module 2 which is entitled as “Individual health”. The word holism is a Greek word that signifies entire or whole. According to Merriam-Webster dictionary, holism is a theory that the universe and especially living nature is correctly seen in terms of interacting wholes (as of living organisms) that are more than the mere sum of elementary particles. Holism in nursing can be referred to as holistic nursing which…
