I believe that blood pressure rises and falls in a pattern corresponding to the phases of the cardiac cycle. The maximum pressure achieved during ventricular contraction is called the systolic pressure while the lowest pressure that remains in the arterial system during ventricular relaxation is the diastolic pressure.
Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.
I think it's anemia thanks
invasive species cost the United States more than $120 billion in damages every year.
