paragraph description of the ventilation without perfusion and 1 for perfusion without ventilation. What is occuring in deatils

Expert Solution

The exchange of air between the lungs and the atmosphere thereby oxygen bis exchanged with carbon dioxide in the alveoli. Perfusion is the passage of fluid or any blood substitute through circulatory system or a tissue. In other words ventilation is the air that reaches the alveoli and perfusion is the blood that reaches the alveoli through capillaries.

An area with perfusion but there is no ventilation is known as shunt. In a right Anto left shunt a portion of pulmonary blood is shunted away from alveoli results in low V/Q ratio. The area with ventilation but no perfusion is known as dead space. Alveolar dead space occurs when alveoli not perfused, results in high V/Q ratio. The ventilation ratio is the ratio used to assess the efficiency and adequancy of 2 variables which means balance between ventilation and perfusion.

Diagram the negative feedback loop for the homeostatic regulation of blood PO2; identify the sensors, integrators, and effectors in this system. 3. What are the critical modulators of respiration in water and air breathing animals? (i.e. what respiratory gas has primary influence on ventilation?)

The ventilation/perfusion ratio: a) decreases when ventilation is increased b) increases due to dialation of the pulmonary arteries c) increases when blood flow is decreased d) is lowest at the apex of the lungs

Which of the following is true about ventilation-perfusion coupling?

Which of the following is true about ventilation-perfusion coupling? in alveoli where ventilation is inadequate, the partial pressure of oxygen is high terminal arterioles dilate in areas where the partial pressure of oxygen is low blood is shifted towards alveoli with low partial pressure of oxygen to enhance oxygen pick-up from lungs in alveoli where ventilation is maximal, the partial pressure of oxygen is low terminal arterioles dilate in areas where the partial pressure of oxygen is high
