Kama tusingekuwa na kinga ya mwili tungekuwa tunaugua kila mara. Hii ni kwa sababu, katika mazingira yetu kuna viini mbalirnbali vya magonjwa. Viini hivyo vinaweza kuingia mwilini kupitia mdomoni tunapokula na puani wakati wa kuvuta hewa. Pia, vinaweza kupitia kwenye ngozi na hasa sehemu zenye michubuko au jeraha.

Kinga ya mwili imegawanyika katika sehemu kuu mbili, kinga ya asili na isiyo ya asili. Kinga ya asili ni ile ambayo mtoto anaipata kutoka kwa mama yake. Kinga hiyo huipata anapokuwa tumboni na wakati wa kunyonya maziwa ya kwanza ya mama.

Kinga nyingine ya asili ni ile inayotengenezwa ndani ya mwili na sell nyeupe za damu. Kinga hii hutengenezwa pale mtu anapopata ugonjwa kwa mara ya kwanza. Baadhi ya vimelea vya magonjwa vikiingia mwilini, mwili hutengeneza kinga kupambana navyo. Kinga zisizo za asili ni zile ambazo hupatikana kwa njia ya chanjo. Hizi husisimua mwili iii utoe kinga dhidi ya ugonjwa unaohusika

Maswali

1. Kwanini hatuugua mara kwa mara?...........................................................................

Read the passage below carefully and then answer the following questions.

Matter is anything that occupies space and has weight. There are three states of matter; solids liquids and gases. The solids have closely packed particles. The closeness of the particles in solids gives them a definite shape and volume. In liquids, the particles are far apart than solids but close together when compared to gases.

The liquids have a definite volume but take the shape of the container in which they are placed. In the gases, the particles are further apart and this makes the gases to lack both definite shape and volume. When the gases are put in a container, they fill up the whole space.

QUESTIONS

21.Which state of matter has no definite shape and no definite volume?

22.Which state of matter has both definite shape and volume?

23. Which state of matter has definite volume but no definite shape?
