Individuals involved in relatively minor accidents may suffer cuts and bruises but generally do not suffer from excessive blood loss. What features does blood possess that limit blood loss during minor accidents?

What will be an ideal response?


Blood loss can be limited by a process known as hemostasis. Hemostasis relies on vascular spasms, or muscular contractions of blood vessels in the region of the damage, formation of a platelet plug at the site of the damage to a blood vessel, and a multistage process of blood clot formation. Once blood loss is stopped, the blood vessels can be repaired, and blood volume returns to normal levels.
