hemoglobin is the molecule within red blood cells that carries oxygen. Each red blood cell can carry 4 molecules of oxygen. Hemoglobin is mainly composed of iron which is why people deficient in iron (more frequently women) can become tired and light headed especially when exerting themselves. This is a result of a decreased ability to carry oxygen in the blood there by starving the brain and organs of the life sustaining gas.

What is a human haemogoblin?
haemoglobin is the iron-based substance in your blood that allows oxygen to be carried around the body. Is this what you meant?
What is the function of haemogoblin in the blood?
the function of haemoglobin is to trap oxygen, it actualy the component of the red blood cell wich carries oxygen.
Is iron necessary for oxygen transport in red blood cells?
True. Iron is necessary in the transportation of oxygen in red blood cells, it is the iron molecules that binds the oxygen molecules to the cell, if you have an iron deficiency (anaemia) it means that your blood isn't carrying enough oxygen around your body. This can cause fatigue as well as other health problems.Note:Humans have iron-based hemoglobin, which gives their blood a red color. Most molluscs and arthropods use hemocyanin, a substance that uses copper in stead of iron, to bind and transport oxygen. So technically, iron is not needed: other substances could perform the same function. The blood would not be red though: in molluscs and arthropods, the blood has a green/blueish tint.
What other body systems does the circulatory rely on or help?
Gas Exchange· When you think about how the cardiovascular system works with other body systems, you probably think of the respiratory system. This is because the circulatory system has a direct path through the lungs. When blood returns from the body to the heart, it is depleted of oxygen. It has to pick up oxygen in the lungs before it can return to circulation. The deoxygenated blood first enters the right atrium of the heart then fills the right ventricle. From the right ventricle it is pumped to the lungs via the pulmonary artery. The pulmonary artery passes the blood through the lungs via capillaries surrounding thin membrane sacs called alveoli. The blood and alveoli exchange oxygen and carbon dioxide. The newly oxygenated blood travels back into the heart by way of the pulmonary veins. The pulmonary veins deliver the blood into the left atrium, which empties into the left ventricle. The left ventricle pumps the blood into circulation throughout the rest of the body. The digestive system passes nutrients into the blood for distribution around the body. The kidneys remove wastes from the blood. The endocrine system uses the circulatory system to distribute hormones.
