12. Say: The human body is a wonderful machine. Everything works
together to keep the body alive and functioning well.
Have you observed how houses are built?
What will the construction worker do first?
Is there a framework in our body just like in building a house?
What do you call the framework in human that provides structure to the
human body?
Today we will learn about skeletal system.

13. The Skeletal System
The skeletal system is the framework of the
body. It is composed of bones, bone marrow,
joints, cartilage and ligaments. The bones support
and give shape to the body. The bone marrow
produces red blood cells.
The joint is a place where two bones meet. The
cartilage covers the bones with a fluid to make the
movement easier. Ligaments are connective
tissues that holds the joints together.

16. The Musculoskeletal System
The musculoskeletal system is an organ system that gives human ability to move
using muscular and skeletal system. Your bones, joints, cartilage, ligaments,
muscles, and tendons make up your musculoskeletal system.

17. A bone is a tough structure in the body that is
made up of connective tissues surrounded by
minerals. An infant has 350 bones, a child has 208
bones and a normal adult has 206 bones. The
bones support and give shape to the body. Without
them the body will collapse. Bones also protect the
soft tissues and the organ of the body. The skull
protects the brain; the ribs protect the heart and
lungs; and the backbone protects spinal cord.
Bones contain a soft tissue called bone marrow that
produces red blood cells.

18. To allow motion, different bones are
connected by joints. Joints are held
together by Connective tissues that can
stretch called ligaments. In order to
make movement easier, the ends of the
bones are covered with a layer of
cartilage with fluid in the space
between them to protect joints and
facilitates movement.

19. Muscles keep bones in place and also
play a role in the movement of bones.
A tendon is a band of tissue that
connects muscle to the bone. Muscles
contract to move the bone attached
at the joint. Muscles that move your
bones work in pairs. When one
contracts, the other must relax.

21. Supply the missing word from the list of words in the box.
Our skeleton is very useful. They have three functions:
_______________, support and stability. The _________
protects the brain and the ________protects our heart and
lungs. Without _________ our body would have collapse.
Bones are connected
by_________. Likewise, knees are joints. Muscles are
attached to the ____________ of our skeleton. They allow our
bones to ____________ by contracting and expanding.
Muscles usually work in ________.

22. Why should bones be strong? Why is it important to prevent falls and
other accidents that could injure the bones?
Why is it dangerous to move a person with spinal fracture?
How will you take care of your bones?
Did you know?
Bones are alive. They are made of living cells capable of growing and
repairing themselves.

23. What are ideas did you learn in the lesson?
What are the parts and functions of the skeletal system?
Describe the potential consequences if all bone tissues in humans were
made of spongy bones & no compact bones.

24. Use the word below to identify parts of the skeleton.

59. HOW THE ORGANS OF EACH ORGAN
SYSTEM WORK TOGETHER

60. Review on the parts of integumentary system.

61. Ask the pupils:
1. Have you eaten your breakfast?
2. Why do we need to eat food?
3. How do you feel when your hungry?
4. Have you ever wondered what happened to the food you have just
eaten?
5. What process it undergoes until it becomes the nutrients that will
nourish your body?

62. Find the missing letters.

63. What is the magic word?

64. Digestive System
Food provides energy to our body. But our body
cannot use this energy from food
unless it is broken in a simple form. The process
of changing food from a complex form to a
simple form which the body can use is called
digestion.
The digestive system consists of the mouth,
esophagus, small instestine, and
accesoory organs which include the salivary
gland, gall bladder, liver and pancreas.

65. Digestion starts in the mouth. When you chew, the saliva in the mouth
moisten the food and help to digest it. When you swallow the tongue
pushes the chewed food to the back of the mouth and into the throat down
to the esophagus through the peristalsis movement (motion of the
muscles that tighten and relax).
Then the food that enters the stomach
is now a soft mass. The lining of the stomach has many glands called
gastric glands that contain enzymes which help in the digestion of
proteins.

66. Before the food reaches the small intestine, it is mixed with fluid from the
liver and the pancreas.
The liver produces bile which is stored in the gallbladder. The bile heps
digest fats. The pancreas releases pancreatic juice that helps in the
digestion of carbohydrates, fats and proteins. In the small intestine final
digestion takes place.
The digestives juices changes the food into soluble substances that can
pass through the villi, the fingerlike projections. From the villi,the digested
food goes through the bloodstream and is distributed
to all parts of the body.

67. The undigested food moves to the large intestine. The walls of the large
intestine absorbs water that leaves a solid mass.This waste collects at
the rectum and is carried out in the anus when the sphincter muscle
contracts.The solids becomes feces and the liquid becomes urine.

68. Identify the organs of digestion being described. Select your answer
from the list.
______ 1. a long coiled connected from the stomach.
______2. a long muscular tube that connects the pharynx to the throat to the
stomach.
______3. a large J-shaped organ at the end of the esophagus, on the left side of the
body.
______4. Is the first part in the digestive system composed of teeth and the tongue.
______5. a large coiled tube attached to the end of the small intestine.

69. Place the events in the correct order. Number each
sentence 1-5.
___ 1. Food ends up in the small intestine.
___ 2. Food is chewed up.
___ 3. Food is in the large intestine.
___ 4. Food travels through the esophagus.
___ 5. Food waste leaves the body.

70. Why is breakfast considered as the most important meal of the day?
TRIVIA: Borborygmus
Borborygmus is the rumbling sound in the stomach. When you hear your
stomach rumbling, it is the signal from your brain that the stomach has
begun the digestion.

75. Day 5

76. HOW THE ORGANS OF EACH ORGAN
SYSTEM WORK TOGETHER

77. Review on the parts of the digestive
system.

78. Show the pupil pictures of children playing.
Ask the pupils:
What are the parts of the body involved in playing?
How do you feel after running?
What makes the body function well when doing activities?

79. Show picture of heart, blood, and blood vessels.

80. Circulatory System
The circulatory system is responsible for the
transport of water, nutrients and oxygen to the body
cells. It also eliminates wastes from the body. The
circulatory system consists of three major parts: the
heart, the blood and the blood vessels.
The heart is a hollow, muscular organ about the
size of a fist that pumps blood continuously
throughout the body.

81. It has four chambers: the left and right atria in the upper chamber; and
the left and right ventricles in the lower chamber.
The atria are the receiving chambers. When the atria contracts, blood is
pumped into the ventricles.
The ventricles are the pumping chambers of the heart. When
they contract, oxygen-rich blood is forced away from the heart
for the distribution to the different body parts. The valves in
the heart prevent the blood from flowing back.
The blood vessels are hollow tubes that permit the blood to flow from
the heart to thebody cells The three kinds of blood vessels are the
arteries, veins and capillaries.

82. Arteries have thicker walls because the blood flowing through them is
flowing rapidly under very high pressure since it has just come from the
heart. Arteries branch out into tinier tubes called arterioles which end up
in capillaries.
It is in the capillaries that exchange of oxygenated and
deoxygenated blood takes place.
Veins transport blood back to the heart.

83. The blood is the transport sytem of the
body. After it is pumped from the heart, it
carries the essential supplies all over the
body. Blood is composed of plasma, red
and white blood cells and platelets. .
The red blood cell carries oxygen and
nutrients; the white blood cells fight
againts infection and the platelets help in
clotting of the blood.

84. How Does Blood Flow Through the Heart?
The left atrium receives oxygen richblood from the lungs. The blood flows
down to the left ventricle through the mitral valve.
The atria contracts and pushes the blood into the ventricle, then the
ventricle contracts pushing the blood into the arteries through the aortic
valve.
The arteries carry the blood to all parts of
the body.

85. After delivering the oxygen and the nutrients to the cells of the body, the
blood goes back to the heart contains carbon dioxide and wastes
substances is transportred by the veins from the different parts of the
body to the right atrium. Blood passes through the right atrium
into the right ventricle through the tricuspid valve.
As the right ventricle contracts, it pushes the blood into the lungs
passing through thepulmonary valve and in the pulmonary
arteries.During the contraction, the blood is prevented from going back
by the one-way valves of the of the heart.

87. Remember This
Supply the missing word from the list of words in the box.
The circulatory is the __________system of the body. The heart
________blood continuously throughout the body. The blood
________digested food and oxygen and collects wastes and carbon
dioxide from the cells. The blood vessels are _________of
blood.

88. The human circulatory system functions to transport blood
and oxygen from the lungs to the various tissues of the body.
The heart pumps the blood throughout the body.
