Hint: The word ‘haem’ means haemoglobin which is an iron containing pigment found in red blood cells and the word ‘rrhage’ means excessive discharge or flow. By this you can have an idea that haemorrhage is something related to blood or a blood vessel. This term usually refers to bleeding.
Complete answer:
By looking at the hint, it is clear that haemorrhage is something that is related to bleeding. Now we shall know the other details like what causes haemorrhage and how it happens? From a medical point of view, bleeding is referred to as haemorrhage. The reason why bleeding occurs is when there is damage to the blood vessel, the blood starts expelling out from it. This can happen either internally or externally. When this is internal, it can be life threatening. External haemorrhage can happen when there is a cut on your skin or when bleeding occurs through natural openings. Internal haemorrhage occurs within the body. Haemorrhages can also happen due to vitamin K deficiency because this vitamin is essential for the blood to clot and in its absence, the blood starts leaking continuously without forming a clot. Based on the amount of blood lost, haemorrhages are divided into four classes.
Class I - $15\%$ blood loss
Class II - 15 to $30\%$ blood loss
Class III - 30 to $40\%$ blood loss
Class IV - greater than $40\%$ blood loss

The most common haemorrhage occurs in the brain under the arachnoid layer which functions as a protective layer to the brain and spinal cord. The most common reasons for brain haemorrhages are high blood pressure, trauma, bleeding disorders or any blood vessel abnormalities.
