Hemoglobin refers to a protein, found in red blood cells, that is responsible for carrying oxygen from the lungs to all other tissues of the body. Red blood cells circulate through the lungs and the hemoglobin in these cells pick up (bind with) oxygen. These cells carry the oxygen, in a form called oxyhemoglobin, out to the tissues and cells of the body. Once at the proper destination, the oxy hemoglobin releases the oxygen and becomes hemoglobin again. The red blood cells, carrying hemoglobin (without oxygen), circulate back to the lungs to pick up more oxygen, and the process begins again.
Hemoglobin also refers to a blood test that indicates the amount of hemoglobin in the blood, and thus, how well the red blood cells are able to carry oxygen to the rest of the body
Hemoglobin is a protein which is contained in red blood cells. You can imagine red blood cells as little bags filled with hemoglobin.
When red blood cells pass through the lungs, they get very close to the air that you breathe in. This allows the hemoglobin inside them to bind oxygen from the air. The red blood cells then circulate around the body. When they reach a body part that is low in oxygen, it automatically drops off their hemoglobin. This way, red blood cells supply the entire body with oxygen.
Hemoglobin has a red color. It's the reason why red blood cells are red - and red blood cells are the reason why blood is red. Hemoglobin that has oxygen is a bit brighter red than hemoglobin without oxygen, so there is actually a color difference between oxygenated and non-oxygenated blood, but it's never actually blue like in books.
Hemoglobin carries oxygen in the blood. It is found in red blood cells.

The primary role of hemoglobin is to carry oxygen. This molecule is transported from the lungs to the tissues that need it.
to transport oxygen
The hemoglobin gives the cells its reddish hue and carries oxygen in the cell.
copper's role in iron metabolism makes it a key factor in hemoglobin synthesis
Hemoglobin
Hemoglobin carries the oxygen molecules into the bloodstream.
Iron, found in hemoglobin.
Iron plays a critical role in the formation of hemoglobin.
Heme is the featured component of hemoglobin. Hemoglobin is the red pigment that gives red blood cells their characteristic color and their essential ability to transport oxygen.
Red blood cells are highly specialized for oxygen transport. They lack a nucleus and instead, contain many copies of hemoglobin. Red Blood cells move single file through the capillaries
Respiratory system
No, hemoglobin is a protein.
