Surface Tension Lab Report
Shakespeare Sance
Homework # 4
The factors that would cause the lung to collapse are elastic recoil and high surface tension. And the factors that prevent the lungs from collapse are negative intrapulmonary pressure and surfactant.
During expiration : volume increase and pressure decrease
During inspiration : volume decrease and pressure increase
The role of surfactant is to decrease surface tension by more than 40 times.
And it's effect on surface tension is to prevent them from PO2 in alveolar : 104
PO2 in venous blood : 40
PO2 in atmosphere : 160
PO2 in arterial : 100
PO2 in expired : 120
PO2 in inspired : 160
Co2 is 20 times more soluble in water than oxygen
Anatomical dead space : the section where there is no gas …show more content…
Low compliance : pulmonary edema and cystic fibrosis
High compliance : emphysema : where a person can get air in and can't get it out
O2-Hb dissociation curve:when the curve mov to the right there is less saturation of hemoglobin . When is shift to the left less oxygen release more oxygen bound to hemoglobin.
Situations that would cause more o2 to release are high temperature, low PH , exercise , high co2.
Way O2 are transport: hemoglobin and plasma
Way CO2 are transport : plasma , bicarbonate ion , and carbamino-compounds
Chloride shift : exchange of bicarbonate for chloride across the red blood cell
The role of the phrenic nerve : excite the diaphragm and intercostal muscles , causing breathing movements.
Anatomy respiratory membrane: a simple layer of squamous epithelial of alveolus and a simple layer of squamous epithelial of the capillary very thin, together the alveolar and capillary walls and their fused basement membranes form the respiratory membrane.
Increase in thickness of the respiratory membrane would decrease gas exchange or imputed gas …show more content…
Efferent vasoconstriction: blood flow increase , blood pressure increase and GFR increase.
The role of renin is to cut angiotensinogen to angiotensin 1 and it's secreted when there is sense of low blood pressure.
Everything that are reabsorbed back into the blood has tubular maximum and you exceed the T max , the exceed remind in the urine.
The major hormones that regulates potassium secretion is aldosterone
Acidosis: PH under 7.35
Alkalosis: PH over 7.45
PH: measures free hydrogen ions range from 0 to 14 there is an inverse relationship between hydrogen ions and PH as hydrogen ion goes up PH went down
Three majors ways to buffeting urine : chemical buffer system, bicarbonate buffer system and protein buffer system.
Hypoventilation : PH went down
Hyperventilation : PH goes up
ECF: fluid inside the cell
ICF : fluid outside the cell
More sodium ECF than ICF
More potassium ICF than ECF
Countercurrent system: fluid flowing in parallel tubes in opposite
