Что такое
иммунитет
1) Способность организма (перешедшая по наследству или
приобретенная в течение жизни) защищать себя от болезнетворных
микробов и вирусов, инородных тел и веществ.
2) Способность организма защищать свою целостность и биологическую
индивидуальность.
Клеточный и
гуморальный иммунитет
Виды иммунитета
Естественный врожденный иммунитет - это невосприимчивость ко многим болезням, данная человеку
от рождения. Например, люди не болеют чумой
животных.
Естественный приобретенный
иммунитет вырабатывается в результате перенесенных болезней.
Например, переболев коклюшем, корью, ветряной оспой, люди, как
правило, не заболевают этими болезнями
повторно.
Искусственный активный
иммунитет вырабатывается в результате введения в организм убитых или
сильно ослабленных возбудителей болезни в
форме вакцины. При этом организм вырабатывает антитела против
данной инфекции и после прививки (так называется данная операция)
человек чаще всего не заболевает или болеет более легко. Подобные
прививки делают от дифтерии, туберкулеза, полиомиелита и т.
д.
Искусственный пассивный
иммунитет - это введение готовых антител заболевшему человеку в
форме лечебной сыворотки. Лечебную сыворотку получают из плазмы
крови животных или человека, перенесших инфекционное заболевание.
Такую лечебную сыворотку применяют, например, при тяжелой
инфекционной болезни-дифтерии. Так как при использовании лечебных
сывороток антитела не образуются в организме, а вводятся в него
извне, то они сохраняются в крови очень
недолго. Через некоторое время организм вновь
становится восприимчивым к болезням.

Tips for giving Presentation
Think about the aims of your presentation. Do you
want to inform or entertain your audience?
Think about your audience. Do they already know
anything about the topic? Why are they listening to your
presentation? Choose the most suitable content for them.
Make eye contact with the audience and try to
sound confident when you give your presentation. Make some notes
and use these to remember what comes next, but don't just read
things aloud.
Speak in a loud, clear voice. Make sure you don't
speak too quickly and rush your presentation.
