Always lower-than-normal Hb saturation levels is a condition experienced by thos

Question

Always lower-than-normal Hb saturation levels is a condition experienced by those that move to higher elevations, but long-term altitude acclimatization (in response to a decline in blood O2) stimulates the causes 1. to secrete EPO which 2. Describe Type I and Type ll Alveolar cells: Type l Type 2 Shape Function The solubility of a gas in a liquid is given by Henry's law, which says that the concentration of dissolved gas is proportional to the partial pressure of the gas. 3. Assume all of the following gases are present in the same concentrations inside the alveolus. Rate the order of solubility of the following gases, from most soluble to least soluble across the respiratory membrane. a. b. Nitrogen gas, Oxygen gas, Carbon Dioxide 4. Ventilation-perfusion coupling refers to the fact that the air flow/blood flow to the lung must match the air flow/blood flow to the lung. (circle one) What is the stimulus for bronchiole constriction and dilation in reference to ventilation-perfusion coupling? a. What is the stimulus for arteriolar constriction and dilation in reference to ventilation-perfusion coupling? b.

Explanation / Answer

Ans 1... acclimatisation occurs because of release of erythropoietin from Kidney.

Erythropoietin act on the bone marrow and causes increase in the production of red blood cells which combat anemia

Ans 2...type 1...squamous in shape

Type 2...cuboidal in shape

Type 1 function...these cells are mainly responsible for gas exchange and also maintain the permiablity barrier

Type 2 function...they produces surfactant,they also are pregenagor of type 1 cell.

Ans 3...among these three...carbon di oxide is most sikhne,then comes the oxygen and then comes the nitrogen

Ans 4...ventilation perfusion coupling refers to the fact that air flow air flow to the lung must match the blood flow to the lung.

Stimulus for.bronchilar constructiin or dilation is hypoxia ans hyper capnia

Stimulus for arterial dilation or constriction os nitric oxide
