HIV is a virus that causes AIDS. It does not result from abnormal hemoglobin or abnormal hemoglobin levels.
sickle-cell disease
Hemoglobin.
One cause is a defect in the body's systems to reduce methemoglobin to hemoglobin. The other cause is a mutant form of hemoglobin called hemoglobin M that cannot bind to oxygen.
There are many ways in which a low hemoglobin can occur. Among these include young ladies in their menstruating cycle, pregnant women, blood donating frequently, wounds, nosebleeds, Aplastic Anemia, Cirrhosis, Leukemia, etc. Low hemoglobin usually occurs because the body is too slow to produce more red blood cells, but do not be alarmed yet, go to a doctor before anything. Sometimes a low hemoglobin is actually normal for some people.
Having hypothyroidism can affect your hemoglobin levels because the low levels of thyroid causes the hemoglobin levels to drop too. These are also linked to B12 deficiency and macrocytic anemia.
Anemia is a decrease in the oxygen-carrying ability of the blood. causes decreaes in rbc number inadaquate hemoglobin content in rbc abnormal hemoglobin in rbc.... human anatomy classic
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
If you mean why isn't a cockroaches blood red, it is because they do not use hemoglobin to carry the oxygen in their blood. Hemoglobin is what causes blood to be red.
The primary factor that determines how much oxygen is actually bound to hemoglobin is the partial pressure of oxygen (pO2) in the hemoglobin solution.
super nitric oxide causes vasoconstriction :)
There are a number of reasons why hemoglobin may decrease in diarrhea. Some of these causes could be from a vitamin B12 deficiency, folate deficiency, colorectal cancer, alcoholism or lymphoma.
