2. Regulating PH and ion composition of interstitial fluids. 3.Restricting fluid loss at injury sites (clotting) 4. Defending the body against toxins and pathogens. 5. Regulating body temperature by absorbing and redistributing heat. |
|
|
What are the physical characteristics of blood? What does each consist of?
|
Plasma: Fluid consisting of water, dissolved plasma proteins, other solutes.
Formed elements: all cells and solids. |

|
|
Q. What are some examples of "Spurious Emissions?"
|
A.
- Broadband emissions caused by arcing - Spurious sidebands (splatter) - Harmonic radiation - Spurious outputs caused by parasitic oscillations - Spurious outputs from the oscillator, frequency multipliers, and frequency synthesizer stages - Transmitter noise - Cross modulation and intermodulation |
|
|
What are the general characteristics of blood?
|
-38 degrees Celsius is the normal temperature

|
True.
|
|
|
What is the blood volume in the body?

7% of body weight
|
|
|
The adult male has how many liters of blood?
|
5 to 6 liters of blood.
|
|

|
What is Fractionation?
|
The process of separating whole blood for clinical analysis into plasma and formed elements.
|
|
|
What percentage of blood volume does plasma make up?
|
50-60% of blood volume.
|
|
|
What percentage of water is plasma?
|
90%
|
|
|
What does extracellular fluids consist of?
|
Interstitial fluid (IF) and plasma
|
|
|
What is the function of the extracellular fluids?
|
Materials plasma and IF exchange across capillary walls
i.e.. water, ions, small solutes |
|
|
What is serum? Define completely.
|
Liquid part of a blood sample, in which dissolved fibrinogen has converted to solid fibrin.
|
|
|
Other plasma proteins make up what percentage of plasma? What does it consist of?
|
1% of plasma.
It includes, enzymes, hormones, and pro-hormones. |
|
|
What are the differences between plasma and IF?
|
--Levels of O2 and CO2. Plasma has higher concentrations of dissolved oxygen proteins than interstitial fluid.
--Concentration and types of dissolved proteins: (plasma proteins do not pass through capillary walls) |
|
|

|
60%
|
|
|
What is function of albumins?
|
--Transport substances such as fatty acids, thyroid hormones, and steroid hormones.
--Responsible for viscosity and osmotic pressure |
