Organ Systems Working
Together
Four Pics, one word: Guess the
word by studying how four
pictures are related to each
other. Write the word in the
space below.
Each organ system interacts with at least one other
organ system. Organ systems do not work
independently; organ systems interact with each
other to keep our body functioning.
The systems of the body are interdependent. The
job that one system carries out depends on and
influences jobs carried out by other systems. That’s
why, you should take good care of your body so that
each organ system will function properly.

Organ Systems Working
Together
Have you observed how houses are built? Houses and
buildings are not just wood, concrete, bricks and stone.
Man put frames like steel or wood in buildings to make
them stronger and flexible.
Framing is an early stage of building a house. The
framework in houses is similar with the skeletal system.
The skeletal system provides the structural framework
for the body and protects internal organs such as heart,
lungs and brain.
• Musculoskeletal system: Consists of the skeletal system –bones and joints and the skeletal
muscle system. • Respiratory system takes in oxygen from the air. It also gets rid of carbon
dioxide Organisms exchanges gases with the environment in the process called respiration.
Respiration includes the intake of oxygen and its delivery to the cells of the different parts of the
body and the removal and release of carbon dioxide. Breathing is very vital in life
• Digestive system absorbs water and nutrients from the food you eat. Biting is the first step in
breaking down food. As you chew, the salivary gland makes saliva that carried through tiny tubes
to your mouth to make your food wet and easy to swallow.
• Circulatory system carries oxygen, water, and nutrients to cells throughout your body. The
circulatory system works together with the digestive system in transporting nutrients and
minerals to all parts of the body.
• Integumentary system reduces water loss, contains receptors that respond to touch, regulates
body temperature, and protects the inside of the body from damage. Receptors in skin send
sensory information to the brain.
• Nervous system regulates peripheral blood flow and sweat glands. It regulates activities that
are automatic or voluntary. The autonomic nervous system controls muscles in the heart and the
smooth muscles in internal organs such as intestine, bladder and uterus
Fill in the missing letters of fruits and vegetables to reveal
the magic word.
Match the bone with the major function. There may be more than
one function to certain bones Write the letter of the correct answer
on the blank.
You have already known the different
combination of materials. You are also
familiar with the appearance of solid and
solid, solid and liquid and liquid and liquid.
What precautionary measures should you
observe when using and storing different
materials at home?
Healthful habits that promote proper functioning
of all the organs systems in the body.
1. Exercise regularly
2. Eat a well-balanced and low-fat-diet
3. Live in a clean environment
4. Avoid smoking cigarette or staying with smokers
5. Have a positive outlook in life
Fill –in the blanks: Choose the word of the correct answer on the box
below. Write your answer on your answer sheet
_________1. The system that carries oxygen, water, and nutrients to
cells throughout your body
_________2. It regulates activities that are automatic or voluntary.
_________3. It absorbs water and nutrients from the food you eat
_________4. It takes in oxygen from the air and also gets rid of carbon
dioxide
_________5. The system that comprises the skin and its appendages
acting to protect the body from various kinds of damage.
