Unit 1:
Module 1: The Human Breathing System
Breathe in and out. Notice that your chest and belly are
moving and feel the air passing from the nose. The respiratory system is
responsible for supplying oxygen for our body to keep it moving.

Activity 1: That’s A
Lot Of Grapes
·
Part A
o Observe
a grape cluster closely, and then compare it to the bronchioles and alveoli of
the lungs.
o Both
appearances look the same, each “grape” is similar to the alveoli.
o The
bronchioles were located at the end of the trachea. This is the part where gas
exchange takes place, and is the unit of respiration.
·
Part B
o Label
each part of the respiratory system. Give its
functions.
- The Bronchi is where gas exchange takes place.
Each alveoli resembles a grape, which allows the lungs to easily absorb oxygen
and expel carbon dioxide.
- The respiratory pathway is a series of tubes,
with each path having its own purpose and function
- Whenever an organ system fails to carry it out
its function properly, the whole body would shut down and results to sickness
or death.
Activity 2: Bottled
Balloons
Describe the movement of the diaphragm helps the
lungs
- When you breathe in or inhale, the diaphragm
contracts. Inhaling moves the diaphragm down and expands the chest cavity. At
the same time, the rib cage would also move up and down to provide more space
for the lungs. Air pushes in when there is a higher pressure, and pushes out when
there is a lower pressure.
- When you breathe out or exhale, the diaphragm relaxes.
The lungs and the ribcage would go back to their original size and place,
preparing to inhale again.
Activity 3: Just Go with the Flow
Air first enters your lungs and then into the left part of
your heart. It is then driven by your heart into the bloodstream, all the way
through your body. The heart pumps blood, which transports essential nutrients,
oxygen, and other chemicals to every cell in your body. Onc it reaches the
cells, oxygen processes the nutrients to release energy. Carbon dioxide it given
off during this process. The blood delivers carbon dioxide into the right
portion of your heart, from which it is pumped to the lungs. Carbon dioxide
leaves your body through the lungs when you exhale.
The Circulatory
System
The circulatory system is the life support structure that
nourishes your cells with nutrients from the food you eat and oxygen from the
air you breathe. It can be compared to a complex arrangement of highways, avenues
and lanes connecting all the cells together into a neighborhood. Sequentially,
the community of cells sustains the body to stay alive. Another name for the
circulatory system is the cardiovascular system. The circulatory system
functions with other body systems to deliver different materials in the body.
It circulates vital elements such as oxygen and nutrients. At the same time, it
also transports wastes away from the body.

Activity 4:
Let’s Organize
Explain the different types of circulation
Activity 5:
Pump It
The heart is a hallow muscular organ, about the size of your
fist, which is located in the center of your chest with a slight degree facing
to the left. Every side is divided into two chambers, the atrium and the
ventricle, each of which has left and right portion, totaling to four chambers
altogether. The top chamber is the atrium (plural: atria). The bottom chamber
is called the ventricle. The valve acts as a one-way door, allowing blood to
flow either forward into the next chamber, or out of the heart.
Activity 6: The Rhythm
Each
time your heart beats, it delivers oxygen-rich blood to your body, which allows
it to function properly. Your heart rate or pulse is the number of times your
heart beats in a minute (BPM or beats per minute). Shorter time intervals may be
used in taking the pulse as long as it comes to 60 seconds upon multiplying
with a factor. When you are resting, your heart rate slows down, as your body
does not need as much blood as it does when you exercise.
Activity 7: Cigarette Smoking is
Dangerous to your Health
Cigarette smoking harms nearly every organ in the body,
causing many illnesses and affecting health in general. The negative effects of
smoking on circulatory system include increased heart rate and blood pressure,
coronary heart disease, arteriosclerosis, and vascular diseases. The
respiratory diseases caused by smoking are chronic bronchitis, emphysema,
asthma, cough, colds, tuberculosis, lung cancer, and other respiratory
infections.
Activity 8:
Prevention is better than Cure
The leading causes of death around the world are diseases
affecting the respiratory and circulatory systems. However, they can be
prevented simply by having a lifestyle that promotes wellness. Circulatory and
respiratory diseases begin to develop with unhealthy living. Symptoms of these
illnesses must not be neglected and appropriate cure must be given immediately.
The best way to prevent diseases in the respiratory and
circulatory systems is to have a healthy lifestyle, which includes balanced
diet, regular exercise, adequate rest, proper hygiene, and avoiding vices such
as cigarette smoking and alcohol drinking. Circulatory and respiratory disease
can easily be detected with regular health check-up and physical screening.
Activity 9:
The best way to
prevent diseases in the respiratory and circulatory systems is to have a
healthy lifestyle, which includes balanced diet, regular exercise, adequate
rest, proper hygiene, and avoiding vices such as cigarette smoking and alcohol
drinking. Circulatory and respiratory disease can easily be detected with
regular health check-up and physical screening.
Several lifestyle choices can affect a person’s risk for
developing respiratory and circulatory diseases. Negative lifestyle weakens
your system while healthy lifestyle leads to complete wellness. Vices,
stressful environments, and unhealthy eating habits can cause various diseases,
specifically of the respiratory and circulatory systems.
