1 Answer

Answer :

: Blood is the name given to the red fluid that carries nutrients through various ducts in human body. This blood needs fluid to be transported so 55% of the blood is fluid. The remaining 45% are blood cells. These blood cells are again of three types , - 1. Red blood cells 2. White particles. 3. Nucleus. White blood cells are again divided into two parts in shape and structure. A. Granular B. Granular neutrophils are a type of granulocyte . The cytoplasm of this cell is color-neutral and fine-grained. The nucleus consists of 2-6 segments. Their diameter is 10-12 micrometers. The phagocytosis method prevents the attack of the disease by eating the germs.
