What is increased blood supply in part of the body?
Hyperemia
What is the difference between erythema and hyperaemia?
Erythema is the physical sign of redness of an ectodermal structure like skin or the exocervix. It is caused by Hyperemia, which is the presence of increased blood flow to a particular structure. Erythema is a physical sign, while Hyperemia is a physiologic process. Hyperemia can also occur in other parts of the body like in a myocardial infarct.
How the fluted filter paper increased the rate of filtration?
Rate of filtration can be increased by using fluted filter paper.rate of filtration is related to surface area of the filter medium.In case of fluted filter paper surface area is increased ,as by folding the paper in such a way,the larger area of filter paper can be confined in the same funnel.so rate of filtration increases.
List the cardinal signs of inflammation and the causes of each sign?
Rubor (Redness) - Vasodilation, local hyperemia that occurs when atrioles dilate. (remember that hyperemia is due to an increased metabolism often induced by a fever.) Tumor(Swelling) - Exudate, fluid containing clotting factors and antibodies seeps from the blood into the tissue spaces. Calor(Heat) - Vasodilation, local hyperemia that occurs when atrioles dilate. (remember that hyperemia is due to an increased metabolism often induced by a fever.) Dolor(Pain) - Edema presses on adjacent nerve endings contributing to the sensation of pain. Also the sensitizing effects of releasing Agranulocytes(prostaglandins and kinins.
What is diapedisis?
Increased capillary permeability allows leukocytes to pass from the vessels into tissues
What causes edema that occurs during the inflammatory process?
Increased capillary permeability
Indication of increased segmenters in CBC?
Due to bacterial infection.. :)
What is the indication when segmenters are elevated?
increased segmenters indicates viral infection
What happens if you increased the driving pressure?
Filtration rate will increase
What clinical situations would you expect edema?
Burns( which result in increased capillary permeability to plasma proteins)
What is the cause of erythema?
Skin injury of any kind will often cause increased blood-flow (hyperemia) in the capillaries immediately below the skin, which results in erythema, which is a redness in the skin (erythr/o = red).
What factor will increase the net filtration pressure to move fluid out of the capillaries?
Increased blood hydrostatic pressure.
