The only thing that they have in common is that they are proteins. Insulin is a molecule that carries glucose across the body cell membranes. Hemoglobin is a very large molecule that contains iron and carries oxygen. The red blood cells are packed with it.
The blood moves around the body inside the circulatory system. This is made up of arteries, veins and capillaries. The blood keeps moving through these blood vessels because it is pumped by the heart. Valves prevent the blood from flowing backwards. The blood always circulates through the body in the same direction.
Yes. Some oxygen leaves your body when you exhale. The process of respiration is a long one, and it works in conjunction with several other processes in order to supply your cells with the adequate energy to live. Inhalation brings in O2. That is a breathable air compound made up of 2 molecules of oxygen. When you exhale, you release CO2. That is carbon dioxide, which, in excess, would be a poison if it remained in our body. The dioxide, however, denotes that this molecule is not only one carbon, but also 2 oxygen atoms. So technically speaking oxygen IS removed from the body during exhalation.
Oxygen is important to human body because it aid in breathing
Oxygen is indispensable for respiration.
Hemoglobin is found in blood, or more specifically red blood cells. It is used there to transport gases (oxygen, carbon dioxide, etc.) throughout the body.

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.
The molecule that bind oxygen in the blood stream is hemoglobin. The O2 attaches to the molecule allowing it to be carried around the body to the other cells.
