Does oxygen dilate blood vessels?
No, oxygen does not dilate blood vessels. In fact, oxygen has a vasoconstrictive effect, which means it causes blood vessels to constrict or narrow. This helps regulate blood flow and pressure in the body.
Why does clotting of blood not take place in uninjured blood vessels?
Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.
