Which is more electronegative O or Se?
Oxygen is more electronegative than selenium.
Is there more oxygen in seawater or air?
There is more oxygen in the air.
Why kerosene has more surface tension than water?
It doesn't.
Does oxygen atoms become more stable or less stable when oxygen forms compounds?
Oxygen becomes more stable when it forms compounds.
Is calcium more electronegative than oxygen?
Oxygen is more electronegative than calcium. The electronegativity of calcium is 1, and the electronegativity of oxygen is 3.44.
What are causes of dark venous blood?
it has more oxygen than arterial blood
Why does oxygen diffusion from the alveolus to the alveolar capillary occur?
Diffusion (of anything) occurs because of a concentration gradient meaning there is more oxygen in one place than another. Alveolus when you inhale will have a higher concentration of oxygen that that of the alveolar capillary resulting in a concentration gradient, this causing diffusion to occur until equilibrium is met. This means more oxygen in alveolus so oxygen travels into the alveolar capillary until a balanced amount of oxygen is in both places, but then of course the oxygen is transported and you exhale and inhale so the process repeats.
What substance is made by the lungs to help reduce the surface tension of water in the alveolar?
Pulmonary surfactant...see link for more information.
How does arterial blood and venous blood differ with regard to their oxygen and carbon dioxide content?
Arterial blood have more Oxygen and venous blood have more CO2 except the pulmonary vien which carry oxygenated blood to the heart for pumping to arteries.
Why CO2 is more in alveolar air than expired air?
CO2 is more concentrated in alveolar air compared to expired air because gas exchange occurs in the lungs where oxygen is taken up by the blood and CO2 is released into the alveoli. Additionally, more CO2 is produced in the body through cellular respiration, contributing to its higher concentration in alveolar air.
Is blood in veins have oxygen?
Oxygen never fully dissociates from the haemoglobin in the red blood cells. There is a lot more oxygen in arterial blood, but there is still oxygen in veinal blood too.
What the rationale for taking body temperature before doing ABG analysis?
ABG (Arterial Blood Gases) is a measurement of oxygen saturation in the arterial blood which supplies oxygenated blood to the body tissue and the extraction of oxygen from the hemoglobin at the capillary level. The amount of oxygen saturation of the hemoglobin (HbO2) depends on hemoglobin concentration and the arterial pressure often referred to as Hemoglobin / O2 dissociation curve. At lower body temperature, less oxygen is bounded to hemoglobin, while at higher temperature slightly more oxygen is bounded to hemoglobin. It is therefore important to know the body temperature when the ABG analysis is done so as to have a more meaningful interpretation of the result.
What does an oxygen saturation level of 66 percent mean?
It means 66% of the hemoglobin molecules are oxygenated. This is a very low reading for arterial blood -- not compatible with life (for a human) for more than a few minutes -- though it might be seen in venous blood. Normal arterial oxygen saturation percentage is in the 90s.
How does oxygen travel through the blood stream at the alveolar wall until it reaches a tissue in the body?
Bloods vessels i think and veins *will need much more detail than that, thanks!
What is the significant difference between the attached gingiva and the alveolar mucosa is that the alveolar mucosa is?
not keratinized and, therefore, is more delicate than the gingival tissue
Why arterial blood is more alkaline than venous blood?
pulmonary arterial blood as it has moce CO2 than venous
What is the function of alveolar sacs?
The alveoli increase the total surface area of your lungs, which allows more gas exchange to take place. The alveolar membrane acts as an interface for oxygen to diffuse into the bloodstream, and carbon dioxide to diffuse out of the blood.
