An Easy Guide to the Heart, Blood Vessels, and Respiration | Health Exercise Instructor Learning Day 2

To understand how exercise affects the body, we will simply organize the basics of the heart, blood vessels, and respiration. This content will help you acquire the perspective of 'the power to deliver oxygen' to protect the safety of the elderly as a chiropractor. This is the second installment in a series where we learn the knowledge of a Health Exercise Instructor, one theme per day.

Day 2: Basic Medicine (Mechanisms of the Heart, Blood Vessels, and Respiration)

Today, we will simply organize the 'mechanisms of the body' to understand how exercise affects the body.
This is also the foundation for proposing exercise safely as a chiropractor.

🫀 1. Mechanisms of the Heart and Blood Vessels

■ The heart is a 'pump'

• Right atrium → Right ventricle → To the lungs (receives oxygen)
• Left atrium → Left ventricle → To the whole body (delivers oxygen)


This flow is repeated about 60 to 80 times per minute.

■ Blood vessels are 'roads'

• Arteries: Roads leading out from the heart (carry oxygen)
• Veins: Roads returning to the heart (carry carbon dioxide)
• Capillaries: Narrow alleys. Places where oxygen and nutrients are delivered


The 'coldness' and 'swelling' felt during chiropractic treatment
might be signs that this blood vessel flow is stagnant.

🌬 2. Mechanism of Respiration

■ The lungs are a 'gas exchange station'

• Inhale: Take in oxygen
• Exhale: Release carbon dioxide


The lungs themselves do not move.
The diaphragm and intercostal muscles move, causing the lungs to expand and contract.

■ Relationship between respiration and exercise

When you exercise, you need oxygen → breathing becomes faster
However, if breathing is shallow, oxygen does not enter well.

Therefore,
**Exercise that improves the quality of breathing (respiratory muscle training)** is also important.

💡 3. Effects of exercise on the heart, blood vessels, and respiration

• The heart becomes stronger (can send more blood in one beat)
• Blood vessels become flexible (prevention of arteriosclerosis)
• Capillaries increase (oxygen becomes easier to deliver)
• Respiratory muscles become stronger (less likely to get out of breath)
• Autonomic nerves are regulated (balance of heart rate and respiration improves)


In other words, exercise is
an act of cultivating 'the power to deliver oxygen'.

👵 Perspectives especially important for the elderly

• The pumping power of the heart weakens
• Blood vessels become stiff
• Respiratory muscles decline


Therefore,
exercise that 'delivers oxygen without strain' is necessary.

As a chiropractor,
'This person's breathing is shallow'
'Their feet are cold'
such observations become hints for exercise proposals.

🌱 How can this be applied to chiropractic?

• Can perform treatments and provide verbal guidance to improve the quality of breathing
• Can explain the meaning of blood flow improvement by linking it to 'peace of mind'
• Can propose exercises to 'maintain a body that can walk'
• Can empathize with the anxieties (heart/respiration) of the elderly
