    The seven organizational approaches to studying the human body are body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic to macroscopic, body systems and medical specializes. The body planes and body direction is the division of the body in to sections from front to back, right and left, and top and bottom. These sections are called the midsagittal plane, the coronal plane, and the transverse plane. This approach is used when studying organs and its function or specific areas with in the body like lungs, brain, and joint and tendons. The body cavity is the study of the body cavities and the organs in the cavities. This approach is used when studying certain organs in the body and how a disease affects different organs. The quadrants and regions divides the lower torso into four sections and nine region sections to identify the areas where internal organs are placed. This approach is a good reference to be used when conducting a physical exam of internal organs. The anatomy and physiology is the study of the structures with in the body and how they function in the body. This approach is good to be used when studying the structure and how cell work or the nervous system. Microscopic and macroscopic is the study of the smallest parts of the body and how they come together to make larger parts and more complex structures or systems. This approach is good to use when studying how cells combine to make organ. The Body systems approach is the study of the body’s organs and how they function together in the body. This approach is good to be used when studying the bodies systems such as the circulatory system, the respiratory system and how they function in the body. Medical specialty is the study of the human body for medical uses. This approach is also divided in to many different categories which are the use or study of anatomy, physiology diseases, diagnostic tests, medical and surgical procedures, and drugs. This…

    First, we know that in an eukaryotic cell majority of the organelles are separated with a membrane. All organelles carry out a different task in the cell. For example, in the chloroplast, photosynthesis (method used by plants and other things to get energy from the light of the sun into chemical energy) is carried out. Another example would be in the mitochondria, respiration takes place. Cellular respiration is when energy is collected from sugars and changed into chemical energy called ATP (adenosine triphosphate). Also, in the nucleus, nuclear division (method in which the nucleus divides, which creates segregation of the genome to opposite poles of the cell). Let’s use a modern day example to explain this. Take a group project given in school consisting of 4 members. If each member, go to a separate room and work on the project, there would be physical barriers present. Each person is completing their own task separately. Each organelle carrying out their own task, in their own membrane. This is what the eukaryotic cell is. So basically, the membrane is there so that only the molecules that are needed goes in and out of that particular membrane. In other words, the importance of the membrane structure is to help the organelles carry out their task more smoothly. So if I had to choose which cell that I like best, even though the prokaryotic cell is simple and the most easy to learn, I would say the eukaryotic cell because it seems as if the cell has all of the right organelles to complete any task. It may be bigger and more complex but it’s worth learning…

    Cells—> Tissues—> Organs—> Systems—> Organism.The same type of cells which carry out a specific function are organised into a tissue. For example, a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body do not work individually.An organ is a group of tissue that cooperates to carry out a specific life process. For examples, epithelial tissues form blood vessels. Several organs are organised into a system. Each system consist of several organs which are organised to carry out life processes such as respiration, reproduction and digestion.Various systems in the human body are well organised to carry out all the life processes efficiently. They are able to function because the cellular components work together to ensure the survival of human beings.The human brain is well developed to integrate information's and store them as memory. This allows human beings to have the ability to talk, think rationally, create new things, learn from experience and use languages. The ability to do all these makes us really special compared to other organism.…

    Ch. 1: Biology: Exploring Life 1) Slides 1 and 2: What is the main difference between physiological adaptation (as in sense, respond and adapt to the environment) and evolutionary adaptation? Evolutionary adaptation occurs over generations. Evolutionary adaptation does involve genetic change but it’s the change in traits as a result of genetic change that drives natural selection and evolutionary adaptation (just genetic change alone won’t drive evolutionary change). Physiological adaptation is an adjustment to environmental stress.…

    I am going to go through and define each of the 7 approaches in my own words. The first is Body planes and body directions. Body planes and directions divide the body into two sections, and the body directions represent movement toward or away from these sections. The second is Body cavities are areas within the body that house the organs of the body. For the third Organizational Approach, Quadrants and regions, the quadrants are 4 different areas right upper quadrant RUQ, left upper quadrants LUQ, right lower quadrant RLQ, and left lower quadrants LLQ. Regions consist of 6 different areas of a specific part of the body. Also Anatomy and physiology are the study of something, anatomy is the study of the relationship between body parts, and physiology is the study of the body as a whole. Then there is Microscopic to macroscopic word "microscopic" describes something that is so small that it can only be seen with the aid of a microscope, macroscopic" refers either to something that can be seen with the naked eye or, something that is large or in scale. The 6th out of seven Body systems are the organs, nerves, tissues circulatory etc. the last is Medical specialties. Medical specialties, are specialists that are doctors who have completed advanced education and clinical training in a specific area of medicine…
