A person with low hemoglobin may feel dizzy because his blood doesn't have enough oxygen-carrying capacity. The brain requires large amounts of oxygen, and may be the first organ to notice a deficiency.
LOTS of haemoglobin (Hb) molecules to carry oxygen. (ie. ~100 million Hb/red blood cell). Immature red blood cells have few Hb in each blood cell.
Hb (or HB) in anatomy and physiology stands for hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the body's tissues and removes carbon dioxide from them. Hemoglobin also gives blood its red color.
The protein haemoglobin found in red blood cells binds reversibly with oxygen. It is the oxygen transporter in blood, and when combined with oxygen the product is oxyhaemoglobin. One haemoglobin molecule binds with four oxygen molecules in accordance with the chemical equation: Hb + 4O2 -> Hb(O2)4 Note: Hb is haemoglobin; Hb(O2)4 is oxyhaemoglobin
Given the total Hb concentration, and the mean corpuscular Hb concentration, Hct can be estimated using the formula Hb/MCHC x 100
This is the theoretical maximum volume of oxygen capable of binding to one gm of hemoglobin (Hb) multiplied by the % saturation of the hemoglobin. Practically, if one knows the amount of Hb per volume of blood then one can determine the volume of O2 carried by blood solely by Hb. Let us assume the following values:[Hb] = 15gm/100mLO2 bound per gm of Hb = 1.39 mLand O2 saturation = 97.5%...ThenO2 carrying capacity of 100 mL blood due to Hb = 15 x 1.39 x 0.975= 20.33 mL O2/100mL

Hb means hemoglobin in the medical context.High BloodpressureMost often Hb stand for hemoglobin, which is a measure of the iron containing part of the red blood cell that carries oxygen.In cardiology it can also stand for heart block.
HB
low level of HB in blood is called manifest iron deficiency.
Some potential experimental errors that could affect hemoglobin (Hb) levels in Sahli's method for estimating Hb include inaccurate measurement of blood volume, improper mixing of blood with reagents, and variability in interpreting color changes due to human subjectivity. These errors can lead to inaccurate readings and affect the reliability of the Hb level determination. It is important to follow the protocol carefully to minimize such errors.
Blood colour is due to the Hb (haemoglobin) in the red blood cells. So it is still correct to say that RBCs are the determinants of blood colour. Eranda alex
