Home pregnancy tests are a qualitative test and measure whether or not hCG -- the pregnancy hormone human chorionic gonadotropin -- is present in your urine, explains Stephen Rechner, M.D., the Division Chief of General Obstetrics and Gynecology at Spectrum Health in Grand Rapids.
After breathing in carbon monoxide, it enters your bloodstream and mixes with haemoglobin (the part of red blood cells that carry oxygen around your body), to form carboxyhaemoglobin. When this happens, the blood is no longer able to carry oxygen, and this lack of oxygen causes the bodyâs cells and tissue to die.
Humans and other animals with lungs cannot tell when they are breathing in carbon monoxide. Carbon monoxide competes with oxygen for binding sites on hemoglobin. Hemoglobin is the molecule in red blood cells that carries oxygen from our lungs to tissues all over our body, and returns carbon dioxide from the tissues.
