Discuss how the human immune system responds to an initial pathogenic exposure and how this initial exposure can lead to a quick
Serga [27]

Answer:

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.

Lisa [10]

Answer:

beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.
