Answer:
increase
an elevated
Explanation:
During heavy exercise, the blood flow in the arteries increases, which eventually creates a net increase in the hydro static pressure of the capillaries. this dilates the blood vessels more mainly at the pre-capillary region than the post capillary region. the capillary hydro-static pressure governs the force that helps to filter blood and moves out fluid from the capillaries to the tissues.
B-cells fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells
