Which type of cell has a life span of four days?

Answer 1

In the human body, the type of cell that typically has a lifespan of about four days is the neutrophil, a type of white blood cell. Neutrophils play a crucial role in the immune system by responding to infections and inflammation. Their lifespan can vary based on the environment and the presence of pathogens, but on average, they circulate in the bloodstream for roughly five to six hours and may survive in tissues for a few days before undergoing apoptosis (programmed cell death).
