Question

how do the circulatory system and immune system work together to respond to an injury?
increase blood flow removes infects cells which prevents infection at the site of the injury.
increased blood flow carries white blood cells to the site of the injury.
increase blood flow kills healthy cells which prevents infection at the site of the injury.
increase blood flow allows for an increase in the exchange of o2 and co2 at the site of the injury

Explanation:

The circulatory system delivers immune cells (like white blood cells) via increased blood flow to injury sites. White blood cells (immune components) then fight pathogens, preventing infection. This collaboration is key to the body’s response to injury.

Answer:

Increased blood flow carries white blood cells to the site of the injury.
