THE SENSE ORGANS AND IT'S PARTS Parts of the Eye: Optic Nerves- it send messages to the brain so that we can recognize the object we saw. 10

THE SENSE ORGANS AND IT'S PARTS THE SENSE OF SMELL NOSE 11

THE SENSE ORGANS AND IT'S PARTS NOSE: the sense of smell The nose makes us smell different things. This sense related to the sense of taste. This is the reason why you have difficulty in tasting food when you have colds. 13

THE SENSE ORGANS AND IT'S PARTS Parts of the nose Nostrils-The two opening in our nose. It is where air enters. Nasal Cavity- A path where air pass. 14

THE SENSE ORGANS AND IT'S PARTS Parts of the nose Cilia-A tiny hair that attatch at the surface of nasal cavity.This hairs filters the air by blocking dust particles and small animals from entering the nose. Mucus Membranes-Found at the surface of nasal cavity which moisten the air and makes it warm. 15

THE SENSE ORGANS AND IT'S PARTS Parts of the nose Olfactory Nerves-It detects the air coming in. This nerves send the smell sensation to the brain. The brain interprets the smell and we finally recognize what the smell is. 16

THE SENSE ORGANS AND IT'S PARTS SENSE OF HEARING EARS 17

THE SENSE ORGANS AND IT'S PARTS The ears catches sound waves. It makes us hear different sounds. 19

THE SENSE ORGANS AND IT'S PARTS Parts of the Ear Outer Ear- the ear we see in our heads. Where sounds from the sorroundings are caught. Ear Canal- a certain tuve where the sounds travel. 20

THE SENSE ORGANS AND IT'S PARTS Parts of the Ear Ear Drum- located at the end of the Ear canal. When sounds waves hit the eardrum, it will vibrates.The motion of the eardrum causes three small bones in the middle ear to move. 21

THE SENSE ORGANS AND IT'S PARTS Parts of the Ear Auditory Nerves- A part of the ear where signals were send.This nerves connected to the brain where it recieves the message from the auditory nerves we can tell the sounds we heard. 22

THE SENSE ORGANS AND IT'S PARTS THE SENSE OF TASTE TONGUE 23

THE SENSE ORGANS AND IT'S PARTS Our tongue helps us taste different kinds of food 25

THE SENSE ORGANS AND IT'S PARTS Parts of the tongue Taste Buds-Found at the surface of the tongue.This are actually nerve endings which can recognize different taste.When we eat something these nerves are able to detect the taste of the food by sending message to the brain. 26

THE SENSE ORGANS AND IT'S PARTS Different Taste of Taste Buds 27
