Today’s lesson is going to focus on «Immunity, types of immunity»After today’s lesson you will be able to describe Immunity, types of immunity compare and identify its features.We will start with Explanation and we will finish with Activity.
Warm up( to set the context and activate prior knowledge)	3 min	T: I want you to look on the presentation. These are the word of outstanding Russian physiologist Mechnikov. «There is no in the word of the unknown, many not understood».There were many questions that humanity could not understand why people are in the same conditions, where there, is a possibility to get an infection, but one of them gets sick and the be explained.Ss: Student expresses their opinions.

Presentation( to present the Lymphatic system)	12 min	T: Now, moving on to Explanation let’s open the text on page 54. I want you to work in groups.1group - active immunity2 group- passive immunity3 group- role of vaccinesYou need to make a poster and present it.Что такое иммунитет1) 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 иммунитетВиды иммунитетаЕстественный 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.
Practice ( to consolidate the material, to check understanding of the topic)		T: Now let’s move on to practical activity. I want you to work in pairs and solve the task. (Teacher gives students the envelope with task on it Attachment 1).Test for primary knowledge control“Choose the correct answer” “Pass the labyrinth” Self-assessment by the algorithm.
