Saurabh Chowdhry

2. DYNAMIC DUOs
 Batman and Robin  Heart and Lungs
work together to protect work together to deliver
Gotham fresh Oxygen to the
body

3. HEART AND LUNGS:
THE ULTIMATE TAG TEAM!!
 The heart and lungs work together in delivering
Oxygen throughout the body.
 Oxygen is needed for many if not most of the
bio-chemical reactions which occur in the body.
SO,
HOW DO THE HEART AND LUNGS
WORK TOGETHER TO DELIVER
OXYGEN THROUGHOUT THE BODY?

4. FUNCTIONS OF THE LUNGS
 To bring Oxygen
(O2) into the body
when we inhale
 To remove Carbon
dioxide (CO2) when
we exhale

5. FUNCTION OF THE HEART
- To pump oxygen-
rich blood through-
out the body.
- The heart must
beat continuously
for a person’s
entire lifespan.

6. HUMAN HEART AND LUNGS

7. VOCABULARY
 Veins: bring blood to the heart
(eg. Pulmonary veins bring blood with fresh O2
from the lungs to the heart).
 Arteries: carry blood away from the heart
(eg. Pulmonary arteries carry waste blood with
CO2 from the heart back to the lungs).

9. SOME INTERESTING FACTS
 When we inhale, air moves down a tract called
the trachea and when we eat, food moves down
a different tract called the esophagus.
 The human heart beats approximately 80,000 to
100,000 times a day.
 This means that in a person’s life lasting 70 to 90
years, the heart beats approximately two to three
billion times!!!!

10. CLINICAL
 Emphysema – lung disease most often caused
by smoking tobacco or air pollution.
- the tissues needed to support the structure
of the lung are destroyed
