Studying the Human Body HCA/220 Susan Calloway June 22‚ 2014 Kathleen Mitchell The human body is an anatomical position that divides the body into planes. Three main planes are frontal‚ sagittal‚ and transverse planes. These planes divide the body into front‚ back‚ right‚ left‚ and top and bottom. Anatomical terms are like reading directions on a compass‚ these terms are useful studying the anatomy it provides a line of communication to avoid confusion when identifying structures. Body planes

the flow of blood in the direction to the brain is blocked‚ due to a lack of oxygen (Ischemic stroke)‚ or when there is bleeding in the brain‚ causing brain cells to damage and/or die (Hemorrhagic stroke). Individuals of an older age are more likely to have a stroke‚ than individuals of a younger age. Individuals who experience a stroke would show the symptoms of sudden weakness; the inability to move (paralysis) or numbness of the face‚ arms‚ or legs usually on one side of the body; confusion; trouble

What chemical compounds does the human body consist of? Oxygen (65%) and hydrogen (10%) are predominantly found in water‚ which makes up about 60 percent of the body by weight. It’s practically impossible to imagine life without water. Carbon (18%) is synonymous with life. Its central role is due to the fact that it has four bonding sites that allow for the building of long‚ complex chains of molecules. Moreover‚ carbon bonds can be formed and broken with a modest amount of energy‚ allowing

2011 Pre-course Learning Objectives: Fluids and Electrolytes: 1. Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and the transcellular fluids such as the synovial ‚ intestinal‚

The Cell P2 – Describe the four main tissue types in the body Inside the body‚ there are four mains types of tissue which include the Epithelial‚ Muscular‚ Nervous and Connective. Tissues are known as groups of cells which have a certain structure to retain a specific job. Epithelial Tissue covers the body surface and forms the lining for most internal cavities. It protects our insides‚ it’s known as the skin. It also absorbs in the intestinal lining and stomach‚ otherwise known as the gut. It

The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

Functionality At Various Ph Level Abstract Enzymes can be denatured at various ph levels in which then affects the shape of the enzymes structure and reactivity. The altering of shape causes substrates to not bind in the active site (Scott Freeman‚ Micheal Harrington‚ Joan. C Sharp‚ 2009). Amylase is used as a catalytic enzyme to determine the time period to convert starch into glucose monomers and transport into the bloodstream at different ph levels. Methods involved are

The human body consists of eleven major organ systems that maintain homeostasis: the skeletal‚ muscular‚ circulatory‚ nervous‚ respiratory‚ digestive‚ urinary‚ endocrine‚ reproductive‚ integumentary and lymphatic systems. These organ systems are dependent on each other to keep the human body in homeostasis. For example‚ the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of

Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:
