The Respiratory system. We breathe oxygen containing air into our lungs. Our hearts send 'old' blood to the lungs where the carbon dioxide is removed and oxygen added, and that oxygen enriched blood is carried around the body until it lands up in the lungs again. So is it really a joint effort by the circulatory system and the respiratory system.
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
From areas of high oxygen concentration to low oxygen concentration, diffusion occurs as oxygen molecules move down their concentration gradient, from where there is more oxygen to where there is less oxygen. This process enables the cells in the body to take in oxygen and use it for cellular respiration, supporting various physiological functions.
A permanent move from sea level to a high-altitude area can lead to an increase in red blood cell production (erythropoiesis) due to lower oxygen levels at higher altitudes. This is the body's way of compensating for the reduced oxygen availability in the atmosphere by increasing the oxygen-carrying capacity of the blood.
Carbon and oxygen atoms are plentiful. However, because such a huge percentage of your body is water and because carbon atoms are always associated with hydrogen atoms in living species, by a long way, HYDROGEN atoms are the most plentiful in a living body.
When hemoglobin releases oxygen and nitric oxide to tissues, nitric oxide causes blood vessels to dilate, increasing blood flow and delivering more oxygen to the tissues. This helps improve oxygen delivery and tissue function.
The circulatory system helps move oxygen throughout your body.
yes. because your body needs oxygen to move. and when you excersize you move more
Exercise and other things that decrease the oxygen intake into your body is what causes hyperpnoea. Your body simply makes you breath deeper and faster to replenish the oxygen your body needs.

When you move your whole body, your muscles require more oxygen, so your heart has to pump blood faster to deliver the oxygen needed. This increased demand for oxygen causes your heart rate to increase to meet the body's needs during physical activity.
Bodies don't produce oxygen. we breathe it in.
by diffusion
Your lungs are the reasons you body has Oxygen. In your lungs, we do produce mucus, which we cough up because of the cilia in our lungs. Smoking causes this cilia to not move the mucus out of your lungs which in turn causes problems.
Lack of oxygen in the body causes hypoxia or cyanosis. Leukemia is the name given to blood and bone marrow cancers. Hypoxia is not a cause of cancer.

emphysema
The lack of oxygen your body has after running causes this. Your body uses up oxygen and makes it hard to take in more to substitute for the amount you are using up.
