B. left atrium trust me. just took the test
B. left atrium
correct answer: left atrium
oxygen:)
Oxygen is inhaled into the lungs and binds to hemoglobin in red blood cells. Hemoglobin then carries the oxygen-rich blood through the arteries to tissues in the body where it is released for cellular respiration. The oxygen-depleted blood returns to the lungs through the veins to pick up more oxygen.
Oxygen molecules are constantly cycling through the environment. They are produced by plants during photosynthesis, consumed by animals during respiration, and released back into the atmosphere. Eventually, oxygen molecules can be broken down by UV radiation into individual oxygen atoms.
98% of the oxygen inhaled enters the blood. However, I do not know where the other 2% goes.
When the oxygen molecule is inhaled it causes a slight explosion which forces the air into your lungs and then up through your veins which gives you better blood flow to your brain. Sometimes rare genetic disorders cause these molecules to be deistroyed so they're not able to explode and usually the blood flow is a lot worse in the people that have this disorder. This can be fixed with a simple medication that is taken daily.
Oxygen is transferred to the cells by our red blood cells which have a special molecule called hemoglobin inside. The hemoglobin molecule binds to the oxygen molecule and the reb blood cells transports the oxygen to wherever it is needed.
The percentage of oxygen in inhaled air by humans is approximately 21%. This oxygen is then absorbed by the lungs and transported by the blood to the cells where it is used for energy production in the body.
The molecule in red blood cells that enables them to carry oxygen is hemoglobin. Hemoglobin is a protein found in red blood cells that binds to oxygen in the lungs and releases it to body tissues as blood circulates. Each hemoglobin molecule can bind to four oxygen molecules.
The molecule that carries oxygen is the hemoglobin molecule. The cell that carries oxygen is the red blood cell.Blood. Red Blood cells. Or Haemoglobin in the red blood cells depending on what level you are looking at.The protein that carries oxygen in the blood is Haemoglobin(hemoglobin).
Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
