3D Medical Mechanics of breathing L v 1 0
Summary
TLDRThe video script explains the mechanics of conscious breathing, highlighting the role of the diaphragm and intercostal muscles in the process. It describes how these muscles work together to expand the chest cavity and draw air into the lungs. The script emphasizes the importance of belly breathing, or abdominal breathing, for filling the lungs completely and maximizing lung capacity, which is crucial for activities like free diving.
Takeaways
- 💪 There are 10 different muscle groups involved in breathing.
- 🏃♂️ The diaphragm is the main muscle used for breathing.
- 🔄 The diaphragm is dome-shaped and helps in expanding the chest cavity.
- 📏 Intercostal muscles are responsible for moving the rib cage.
- 📉 Inhaling involves the diaphragm contracting and moving down, and the rib cage expanding.
- 📈 Exhaling is the reverse process of inhaling, with muscles relaxing and chest cavity shrinking.
- 🌀 The expansion of the lungs reduces pressure, drawing air in.
- 🚗 The action of breathing is likened to a piston in a car engine.
- 🌊 Normal breathing uses about 25% of lung capacity, known as tidal volume.
- 🧘 Belly breathing or abdominal breathing is crucial for activities like free diving.
- 💪 Training can increase the use of lung capacity beyond the normal tidal volume.
Q & A
How many muscle groups are involved in the process of breathing?
-There are 10 different muscle groups involved in the process of breathing.
What is the primary muscle used for breathing?
-The primary muscle used for breathing is the diaphragm.
Describe the diaphragm's shape and its location in the body.
-The diaphragm is a dome-shaped structure located between the chest cavity containing the lungs and the abdomen containing the digestive system.
What are the internal and external intercostal muscles, and what is their role in breathing?
-The internal and external intercostal muscles are the muscles that move the rib cage. They are attached to the ribs and run between them, helping to expand the chest cavity during inhalation.
How do the diaphragm and intercostal muscles work together during inhalation?
-During inhalation, the diaphragm contracts and moves downward, while the external intercostal muscles contract, forcing the rib cage up and out, increasing the volume of the chest cavity and expanding the lungs.
What happens to the pressure inside the lungs when the chest cavity volume increases?
-When the chest cavity volume increases, the pressure inside the lungs decreases, causing air to be drawn in.
What is the term for the amount of air used in normal breathing?
-The term for the amount of air used in normal breathing is called tidal volume.
What percentage of lung capacity is typically used in normal breathing?
-In normal breathing, we use around 25% of our lung capacity, which is our tidal volume.
What is belly breathing or abdominal breathing, and why is it important for free diving?
-Belly breathing or abdominal breathing is a type of breathing where the diaphragm moves further down into the abdomen, pushing the belly out to allow the lungs to expand and draw in more air. This type of breathing is critical for free diving as it allows divers to completely fill their lungs with air.
What is the maximum amount of air the lungs can hold called?
-The maximum amount of air the lungs can hold is called total lung capacity.
How can training help in utilizing more lung capacity?
-With training, one can learn to use more of their lung capacity, which can be beneficial for activities that require deep or controlled breathing, such as free diving.

🫁 Mechanics of Breathing
This paragraph discusses the mechanics of breathing, emphasizing the role of various muscle groups. The diaphragm, a dome-shaped muscle located between the chest and abdomen, is highlighted as the primary muscle for breathing. It contracts and moves downward during inhalation, while the intercostal muscles, which are attached to the ribs, contract to expand the rib cage. This coordinated action increases the chest cavity's volume, allowing the lungs to expand and draw in air. The paragraph also explains the concept of tidal volume, which is the amount of air used in normal breathing, and contrasts it with deep breathing or belly breathing, which allows for fuller lung expansion. It concludes by mentioning that with training, one can increase the use of lung capacity beyond the typical 25%.

mechanics of breathing consciously take
a breath and think about the fact that
there are 10 different muscle groups
working together to make this
happen these muscle groups include the
diaphragm and intercostal muscles the
main muscle used for breathing is the
diaphragm the diaphragm is a dome-shaped
structure consisting of several large
muscles which is sandwich between the
chest cavity containing the lungs and
the rib cage and the abdomen containing
the digestive system including your
stomach the muscles that move the rib
cage itself are the internal and
external intercostal muscles they are
each attached to the ribs and run
between them to inhale air the diaphrag
contracts and moves down while the
external intercostal muscles contract
forcing the rib cage up and out the
combined effect of the diaphragm and
intercostal muscles increases the volume
of the chest cavity and expands the
lungs this expansion of the lungs
increases their volume reducing the
pressure within them causing air to be
drawn in this action is similar to a

in normal breathing we use around 25% of
our lung capacity which is called our
tidal volume as you inhale deeply the
diaphragm moves further down into the
abdomen pushing your belly out giving
more room for the lungs to to expand and
draw in more air this type of breathing
is called belly breathing or abdominal
breathing and is critical to prepare you
for your free dive belly breathing
allows you to completely fill your lungs
with air the maximum amount of air your
lungs can hold is called your total lung
capacity with training you can use more
of your lung capacity
