Question

Need helping writing a lab report I attached all the papers needed for the assignment and I attached my table that shoes the answers that I had got. Acids Bases, Buffers and Respiration: Explain the following terms and provide physiological significance: pH, ionization, acid identifty acidic, neutral and basic pH values .Explain the pH scale in terms of hydrogen ion concentration. . Relate the concentrations of H' to OH in an acidic, neutral and basic solution and base static mechanism that maintains the pH Explain the role of a buffer system as a homeos of body fluld. Explain how a change in pH relates to the concentration of hydr Explain the law of mass action. Be able to predict the direction of ogen ions. when the concentrations of various rea Identify ctants are altered. the carbonic acid/bicarbonate reaction. . .Explain the role of CO2 in acid/base balance. Predict the effect of hyper/hypoventilation on pH. Be able to demonstrate proper use of a pH meter. Construct a formal laboratory report; including graphs to illustrate data, . Background: Homeostasis is the maintenance of a relatively stable internal environment. For cells to survive, the composition of the surrounding fluids must remain relatively stable. If cells survive, the individual survives The internal environment, an aqueous medium, is generally referred to as the extracellular fluid, ECF. It is the extracellular fluids that must be kept within homoeostasis. Extracellular fluid is the fluid outside the cells. It is extremely important as the ECF mediates the exchange of materials between the external environment and the cells of the body, It is the ECF that t body and then transports carbon dioxide and other wastes from the cells to the ext environment. The ECF consists of the following compartments: 1) interstitial or ransports oxygen, nutrients and other materials from the external to the cells of the ernal fluid, 2) the fluid portion of the blood and 3) transcellular fluids or the fluids within epithelial tissue plasma, lined spaces. The interstitial fluids comprise the largest portion of the ECF and the transcellular flu ids comprise the smallest portion of the ECF. Examples of transcellular fluids include cerebrospinal fluid, synovial (joint) fluid and intraocular fluid (fluid within the eyes). 27

Explanation / Answer

A buffer is a solution which can balance between acid and base. blood is a buffer due to presence of the carbonate anion and carbonic acid .

body defends against change of PH:

by - blood buffers

-respiratory system

-excretory system

Respiratory Mechanism

-exhalation of carbon dioxide

-works with volatile acids

-dosnt affect fixed acids like lactic acid

rate and depth of breathing

Acidosis

-depression of central nervous systems through decreases synaptic transmission.

-generalised weakness, coma and death.

Alkalosis

-numbness

-lightheadedness

-weakness

-overactive central nervous system

-convulsions, loss of consciousness , death
