The red blood cells carry the oxygen in blood.
the blood absorb oxygen in the lungs(cappilaries)
Because your cells need oxygen. Blood has Hemoglobins inside it, which carry oxygen.
Oxygen enters the blood in the alveoli of the lungs
An increase in diffusion rates in tissues favours oxygen movement from the capillaries to the tissues, and carbon dioxide from the cells to the blood. Also With some training these rates increase, allowing oxygen and carbon dioxide to diffuse more rapidly.
Increased concentration of oxygen
Excersice increases blood flow, more blood Flow to the brain = increased oxygen= increased energy = increased mental Sharpness! :)
With increased breathing, levels of carbon dioxide in the blood drop and levels of oxygen rise.
oxygen Carbon Dioxide
Decreased Oxygen, increased CO2, Acidosis
the lungs can better exchange oxygen and waste products in the blood.
Activity increased vasodilation because increased activity requires a better blood supply. Resting decreases the dilation of the blood vessels because less blood is needed for oxygen and energy.
-Decreased pH -Increased Temperature -Increased Pco2
I'm assuming you're referring to saturation of oxygen in the blood. If the temperature is increased, oxyhemoglobin curve is shifted to the right, meaning hemoglobin realeses oxygen more readily, thus increasing blood oxygen saturation.
Blood vesseld will dilate to allow an increased blood flow to the working muscels and therefore providing more Oxygen.
Body cells get oxygen and food from blood. So, faster breathing causing increased oxygenation and increased heart rate cause greater blood flow during exercise.
