Verified step by step guidance

Understand the context: Cells traveling through the bloodstream are often subject to various physical and chemical stresses that can affect their survival.

Consider the types of cells: Different cells have different abilities to survive in the bloodstream. For example, red blood cells are adapted to travel through the bloodstream, while other cell types may not be.

Analyze the factors affecting cell survival: Cells in the bloodstream may face immune system attacks, mechanical stress, and lack of attachment to a substrate, which can lead to cell death.

Evaluate the biological mechanisms: Cells that are not adapted to the bloodstream environment may undergo apoptosis or be phagocytosed by immune cells.

Conclude based on evidence: Given the challenges faced by cells in the bloodstream, many cells indeed do not survive this journey, supporting the statement as true.
