What are some non-specific responses of the immune system and how do they protect us from infection?

Some non specific responses in the body caused by the immune system are the release of body cells. (T-cells, T-killer cells, B-cells, B-Helper cells.)

Explanation:

When your body notices an intruding viruses or bacteria, it initiates a chemical response. (Aka your germacide.) You body has two systems that’s work together to kill these intruders, your non specific defense, and you specifics defense. Each has it’s own jobs. The non specifics job is to release you cells to the targeted area. When a cell is detected, and it gets into your blood your B cells will latch onto it and call your other cells to come kill it. Another way you’re non specific defense gets to work is your skin. You body always has germs on its skin, so it produces a anti germ liquid. Sometimes it doesn’t affect them, and sometimes it does. For the germs it attacks, it actually breaks down the cells cell. It’s like a acid for the germ.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
