Haemoglobin is found in-

Correct option is A

The correct answer is (a) Blood.
· Haemoglobin is a protein found in the red blood cells of the blood. It is responsible for transporting oxygen from the lungs to the rest of the body and carrying carbon dioxide back to the lungs for exhalation.
· Haemoglobin contains iron, which binds to oxygen molecules, giving blood its characteristic red color. It plays a crucial role in maintaining the body’s oxygen levels and is vital for energy production and overall cellular function.
· A deficiency in haemoglobin can lead to conditions such as anemia, which results in fatigue, weakness, and shortness of breath due to reduced oxygen transport.
Additional Information:
· Bones: While bones produce blood cells through the bone marrow, haemoglobin itself is not found in bones.
· Bile fluid: Bile is produced by the liver and stored in the gallbladder, primarily aiding in digestion, not containing haemoglobin.
· Sweat: Sweat is a fluid secreted by sweat glands for temperature regulation and does not contain haemoglobin.
