The Position Of Anatomy And Physiology In Nursing
To know the changes that occur in the body of the sick we must first know the structure and function of each tool of the healthy human body in daily life.
knowledge of the anatomy and physiology of the human body is important in carrying out basic nursing care by knowing the structure and function of the human body, a nurse professionals can increasingly clearly interpret the changes contained in the body of the tool.

Anatomy
Anatomy comes from the Greek word consisting of Ana which means separate or parse, and Tomos meaning shredding. anatomy means parse and cut. the science of form and arrangement of the body can be retrieved by means of Untangling the agency through pieces of the body parts and body tools relationship to each other.

8 Branches Of Anatomy
1. Macroscopic Anatomy
anatomy macroscopic is the anatomy study of the arrangement of each tool with the cutting and separating the parts of the body.
2. The Anatomy Of Microscopy
microscopic anatomy is the study of anatomy of each tool's body by using a magnifying glass or microscope, for example, learn about cells and investigations about the network.
3. Systematic Anatomy
systematic anatomy is the science that studies the anatomy of each body contained in the system, each system having the same network form the special functions, such as the muscular system, cardiovascular system and other.
4. Regional Anatomy
regional anatomy is the science that studies the anatomy of layout tools body with each other, it is important to do surgery, for example, know the location of nerves, blood vessels, and others.
5. Developmental Anatomy (Embryology)
developmental anatomy or embryology is the study of changes in the cells ranging from pregnancy until the child is born.
6. Surface Anatomy
surface anatomy is the study of anatomy about the layout tools in the body in projection to the surface of the body.
7. Comparative Anatomy
comparative anatomy is the study of anatomy related to the similarities and differences between the human body and the lower beings (animals).
8. Anatomy Radiology
radiology anatomy is the study of the size of the human body different from one nation with other nations.
The Basic Physiology Of The Body
mechanism and special properties of human body life outside our own control, such as thirst and feel hungry which keep us looking for drink and food; cold feelings make us look for warmth and protection.
humans actually move automatically, we have feelings, thoughts, and knowledge is a series of automatic life allow us to live in a variety of circumstances.
in humans, the cluster of cell specialised functions consisting of the respiratory system to take in oxygen and give off carbon dioxide, and so on layout of work from each system plays, a role in the body's overall function.
the purpose of science is to clarify the physiological factors of physics and chemistry that are responsible for the origin of the development and advancement of the life of a virus or bacteria is the most simple to the most complex and human characteristics functional.

human physiology related to specific properties and mechanical human body that make human beings as foraging at the time felt hungry, seek shelter, looking for relationship with others proliferate, and happens automatically.
we can feel ad understand everything during the life of the series, this special nature allow us to survive under a wide range of conditions.
The Cell As A living Unity
the basic unit of life cell is the body. every organ is the unity of different cells that are connected to each other by supporting intra-cell structure. each cell is specially adapted to perform specific functions, such as blood cells, of which there are about 25 trillion transports oxygen from the lungs to the tissues.
for real each cell certain characteristics and all cells have the ability to reproduce to form new cell to the number of cells that supplies to be enough back.
Body Fluids
simply build the body cells that live in the sea which is the internal fluid extra-cell (CES) wrapped by the skin of the body. from this fluid cells receive oxygen and food, into the liquid cell also secretes metabolic waste extracell fluid moves as not fixed throughout the body and rapidly mixed with blood circulation, blood fluid diffusion network.
there are extracell i the liquid ions and nutrients needed by cells for maintenance functions of the cells. cell alive, growing and perform specific functions for the available of the concentration of oxygen, glucose, various ions, amino acids, and fatty acids that are appropriate with the internal environment.

Liquid Extracell
extracell liquid is a fluid between cells in a tissue relative does not have such a connective network vascular, bone tissue and cartilage tissue, a substance found in appears in the secretions-gland secretions and basically liquids.
Liquid Intracell
intracell liquid is a liquid that is found in cells, controlling the volume of the liquid contained in a intracell form, since the cell membranes are permeable to water, and free macro-molecular which generates the osmotic gradient that is present in the cell.
then there are specific mechanisms that can prevent the inclusion water uncontrollably into the cell that results in swelling of the cells and broke. to prevent this, the cell must be capable of removing the water that has an important mechanism for the exchange of sodium and potassium that are bound to the membrane sodium and potassium.
this can work because the sodium ions bind more water and potassium, even through the sodium atom is much smaller but harder into the cell than potassium out of cells will lead to cell swelling and rupture.
The Style Of The Movement Of Substances
main styles that cause water movement across the news (the screen) is the diffusion, cohesion, filtration, osmosis, active transport and endocytosis. soluble substances across a layer does not move by way of diffusion, the layer is part of the real for the prisioners movement of certain dissolved substances.
Diffusion
diffusion is the event when the gas or substance in a solution which is floating because of the movement of ions, molecules tend to fill the entire room available. the molecules of a substance that dissolves the natural solutions is always in a movement that ends to spread from the region of high concentration to areas of low concentration to the concentration of the same in the entire solution.
the diffusion of ions is also influenced by the electric charge, if there is a potential difference between two regions of negatively charged ions, and ions negatively charged ions move in the opposite direction.
Cohesion Solvent
cohesion is a solvent in a solvent is moving in one direction (mass flow), the solvent tends to drag some of the molecules of a substance is dissolved. this style is called style of drag or cohesion.
Filtration
filtration is the event when a fluid is forced across a membrane or baffle because different hydro-static pressure on both sides, the amount of fluid that in filtration within a certain period than proportional to the difference of pressure and the surface area of the membrane.
molecules are smaller than the pores of the membrane can be shared across a liquid, larger molecules. filtration through walls of capillaries occurs when hydro-static pressure is greater than the pressure in the network outside the blood vessels.
Osmosis
osmosis is the movement of solvent molecules through the membrane towards the areas containing solvent are more concentrated and not seeping through the membrane. molecular motion of solvent's tendency towards areas that have higher levels of the solvent.
the thing can be prevented by using pressure on the more concentrated solution. the pressure needed to prevent the passage of solvent is called the effective osmotic pressure of a solution.
Osmotic Pressure
osmotic pressure is the pressure caused by the particles that do not diffuse in the solution are determined by the number of particles per unit volume of liquid. each particle in solution raises the same pressure against the membrane. factors that determine the osmotic pressure of the solution is the concentration of the solution is viewed in terms of the number of particles.
