How does hydrogen peroxide remove blood stain?
Hydrogen peroxide breaks down the components of blood stains through oxidation, which helps to lift the stain from the fabric. When hydrogen peroxide comes into contact with blood, it reacts with the enzymes and proteins in the blood to break them down, making it easier to clean the stain.

Why does oxygen diffuse from aveoli to blood?
It is due to Diffusion Pressure Deficit, DPD for short. When in the blood as oxyhemoglobin its DPD is almost twice that of cells, thus it passively diffuses into the cells from the blood. A simpler way to look at is that products usually move from high density to low density areas via diffusion.

Blood is bright red due to the high concentrations of oxygen in it. This blood is known as oxygenated blood. Blood that appears dark in color or "blue" is blood that has been used by the body and has a higher concentration of carbon dioxide in it. This blood in known as deoxygenated blood!
Is blood in your veins blue until it comes out of your body and hits oxygen?

How does the foetus get oxygen from its mother?
The fetus receives oxygen from the mother through the placenta. The mother's blood, high in oxygen, passes through the placenta where it comes into close contact with the fetus's blood, allowing for the exchange of oxygen and carbon dioxide. This process ensures that the fetus receives the necessary oxygen for development.
Does saliva with hiv infects you when it comes in contact with your blood?
