0:11 one milk
0:14 base let's learn
0:17 about different organs of the body parts
0:28 system hello kids it's me teacher PR

0:33 like and
0:36 share and hit the notification Bell for
0:39 the latest video you can also follow my
0:42 Facebook page teacher FR [Music]
0:46 [Music]
0:50 TV for today's lesson in science 6 we
0:53 will discuss about different organs of
0:56 the body parts and function of
0:59 musculoskeletal system we are now in
1:01 quarter 2 week
1:05 one for most essential learning
1:08 competencies explain how the organs of
1:11 each organ system work
1:14 together the skeletal system is the
1:20 framework of the body it is composed of
1:22 Bones bone [Music]
1:23 [Music] marrow
1:26 marrow joints
1:28 joints
1:31 cartilage and ligament
1:34 ments the bones support and give shape
1:35 to the
1:40 body the bone marrow produces red blood
1:43 cells the joint is a place where two bones
1:45 bones
1:48 meet the cartilage covers the bones with
1:51 a fluid to make the movement
1:54 easier ligaments are connective tissues
1:57 that holds the joints
2:00 together here are the parts of the the
2:03 skeletal system let's study the upper
2:05 part of the skeletal system
2:07 system
2:11 Cranium face these are parts of the
2:15 skull clavicle collar bone
2:17 bone scapula
2:19 scapula
2:24 sternum ribs humerus or Funny Bone
2:26 Bone
2:29 vertebrae now let's study the lower part
2:30 of the skeleton
2:33 system coxal bone or hip
2:35 hip olna
2:37 olna
2:40 radius carpal bones or
2:43 wrist metacarpal
2:46 bones palanges or fingers
2:48 fingers
2:51 pimmer patella or kneecap
2:53 kneecap tibia
2:54 tibia
2:57 fibula Taral bones or
3:01 ankle metatarsal
3:05 Bones the muscular skeletal system is
3:08 like a frame it gives your body shape
3:11 and support it support your body as you
3:14 move some bones protect some vital parts
3:18 or internal organs of your body some
3:22 bones enable the body to make different
3:25 movement the bones in the head the bone
3:29 forming the head is the skull or cranium
3:32 it is like a built-in helmet is made up
3:36 of eight bones that have grown together
3:40 you have about 2006 bones in your body
3:44 as a baby you had more than 300 bones
3:47 the skull protects the brain it is hard
3:50 and strong but it can be cracked if it
3:51 receives a severe [Music]
3:53 [Music]
3:56 blow the Joe bones support the teeth and
3:59 gums enabling us to bite and chew our food
4:00 food
4:03 the backbones or the spinal colum holds
4:07 your head and body straight it consists
4:10 of 26 separate Bones called vertebrae
4:12 with this made of
4:15 cartilage the cartilage prevents these
4:19 bones from hitting each other when you
4:22 move the vertebrae protects the spinal
4:28 cord there are seven cervical 12
4:30 thoracic five
4:36 bloombar one sacrum and one coxic
4:38 vertebrae if you look closely at one
4:41 vertebra you will see a hole in its
4:45 Center through which the spinal cord
4:49 passes the vertebrae are separated by
4:51 cartilage which prevents these bones
4:54 from hitting each other when you
4:57 move the backbone protects the spinal
5:01 cord your backbone is your main
5:05 support the vertebrae in your backbone
5:07 let you move in different
5:10 ways the skeletal system serves many important
5:12 important
5:15 functions it provides the shape and form
5:18 for the body support and
5:22 protection allows bodily movement
5:27 produces blood for the body and stores
5:30 minerals the number of bones in the
5:34 human skeletal system is a controversial
5:38 topic humans are born with over 300
5:42 bones however many bones fuse together
5:44 between birth and
5:47 maturity as a result an average adult
5:50 skeleton consists of 206
5:54 bones the number of bones varies
5:56 according to the method used to derive the
5:57 the
6:01 count while some consider certain
6:03 structures to be a single bone with
6:07 multiple Parts Others May see it as a
6:13 bones there are five general
6:17 classification of Bones these are long
6:23 bones short bones flat bones irregular
6:27 bones and sesamoid
6:30 bones the human skeleton is is composed
6:33 of both fuse and individual bones
6:35 supported by ligaments
6:38 ligaments tendons
6:41 tendons
6:43 muscles and
6:46 cartilage it is a complex structure with
6:49 two distinct divisions the axial
6:52 skeleton which includes the vertebral
6:59 skeleton and now let's proceed proed to
7:03 learning test one as you start exploring
7:06 the subject answer the following
7:08 questions write your answers on your answer
7:10 answer
7:13 sheet this is a crossword
7:16 puzzle let us find first those words
7:20 across number two filters and eliminates
7:24 liquid wases regulates water balance
7:26 this is
7:29 urinary number three enables gas
7:34 exchange with the blood this is
7:38 respiratory number five enables movement
7:42 maintains posture and can store energy
7:45 this word is
7:48 muscular nine senses external
7:51 environment and communities with and
7:55 activates other parts of the body this
7:57 part is
8:01 nervous number 10 produces gamuts and supports
8:02 supports
8:06 development this word is
8:09 reproductive now let's answer those
8:14 words down those words are number one
8:17 allows ingestion and breaks down food so
8:19 that nutrients can be
8:23 absorbed this is
8:26 digestive number four provides
8:28 mechanical support it stores minerals
8:34 and produces red blood cells this is
8:37 skeletal number six protects the body's
8:41 internal environment and stores fat this is
8:44 is
8:47 integumentary number seven enables the
8:50 transport of nutrients gases and wastes
8:52 to and from
8:56 cells this is
8:59 cardiovascular and number eight secretes
9:01 hormone hormones into the bloodstream
9:04 for regulation of cellular activities
9:07 this is [Music]
9:09 [Music]
9:12 endocrine learning test two use the word
9:15 below to identify parts of the skeleton
9:18 write your answers on your answer
9:21 sheet so let us find the word in the
9:24 bone vocabulary to identify parts of the
9:28 skeleton so this is the human skeleton
9:31 each bone in our bodies has a name there
9:35 are more than 200 bones in our bodies
9:39 for letter A this part is
9:42 called clavicle or colar
9:46 bone letter B this part is
9:50 called umuse or upper arm
9:56 bone letter C this part is called
10:01 radius letter D this part is called
10:07 alna letter e this part is called fer or
10:11 upper leg bone letter F this part is
10:14 called patella or
10:18 kneecap letter G this part is called
10:20 called
10:24 tiia letter H this part is called
10:26 called
10:30 fibula letter I this part is called
10:33 metatarsals or foot
10:36 bones letter J this part is called
10:38 called
10:42 skull letter K this part is
10:44 called shoulder
10:50 joint letter L this part is called rib
10:56 cage letter M this part is called
11:00 spine letter N this part part is called
11:02 called
11:05 felus and for letter O this part is
11:10 called metac car PS or hand
11:14 bones and for learning test three match
11:17 the parts of the skeletal system in
11:20 column A with the functions in column B
11:24 write your answers on your answer
11:27 sheet number one
11:32 skull the correct answer is letter c a
11:35 rigid case that protects the
11:38 brain number two spinal
11:43 column the correct answer is letter B
11:44 protects the spinal
11:47 cord number three
11:52 bones the correct answer is letter A the
11:55 inner layer of the bone that contains
11:58 yellowish substance which manufacture
12:00 blood cells in the
12:05 body number four hinge joint the correct answer
12:06 answer
12:11 is letter e allows movement in One
12:15 Direction number five ball and socket
12:19 the correct answer is letter D allows
12:22 movement in all Direction
12:24 Direction
12:27 remember the skeletal system is the
12:32 framework of the body it is composed of
12:35 Bones bone marrow
12:37 marrow joints
12:40 joints
12:47 ligaments the bones support and give
12:49 shape to the
12:53 body the bone marrow produces red blood
12:56 cells the joint is a place where two bones
12:57 bones
13:01 meet the C cage covers the bones with a
13:03 fluid to make the movement
13:06 easier and the ligaments are connective
13:10 tissues that holds the joints
13:13 together so kids do you understand our
13:14 lesson for today
13:17 today
13:23 job kids I hope you learn a lot from
13:27 this lesson until our next topic bye-bye
13:30 kids thank thanks for watching [Music]
