Presentation about anatomy of the lung

1. The Lungs
By Adnan Hailat & Ahmad Hatem

2. The lungs are the primary organs
of the respiratory system in
humans and most other and
located near the backbone on
either side of the heart.
Their function in the respiratory
system is to extract oxygen from
the air and transfer it into the
bloodstream, and to release
carbon dioxide from the
bloodstream into the atmosphere

3. the lungs are made mostly of
epithelial cells. Epithelial cells
line the airways and make mucus,
which lubricates and protects the
lung. The lung also contains nerve
cells, hormone-producing cells,
blood cells, and structural or
supporting cells

4. The left lung has 2 lobes, the superior
lobe and the inferior lobe.
And the right lung has 3 lobes, the
superior lobe, the middle lobe and the
inferior lobe.
The left lung has fewer lobes to make
room for the heart. In situ, the heart's
apex is tilted slightly to the left, which
makes the left lung smaller than the
right Because of the lack of space.

5. lobules contains a bronchiole and affiliated branches, a thin wall,
and clusters of alveoli

6. The bronchi are the large tubes that
connect to your trachea (windpipe) and
direct the air you breathe to your right
and left lungs
Bronchi are made up of cartilage and
smooth muscle, and they are lined by
mucous membranes. Cartilage
provides structural strength, and the
smooth muscle controls airway
dimensions during respiration

7. The bronchi branches into small
bronchioles. The bronchioles are
part of the lower respiratory
system. As they branch off from
the bronchi, they become
smaller and smaller, traversing
the interior of each lung before
ending at clusters of alveoli.

8. The alveoli are where the lungs and the blood exchange oxygen and
carbon dioxide during the process of breathing in and breathing out

10. The process of inhaling and exhaling
starts with movement of the
diaphragm downward and movement
of sternum outward.
because of this movement space gets
created in lungs and air gets sucked
through nostrils

11. Alveoli is covered with a large number
of blood vessels and due to diffusion
only oxygen gas passes into the blood
vessels and all other gases stay in the
alveoli

12. Inside blood vessel, oxygen
combines with hemoglobin present
in the blood to form oxyhemoglobin
In the cells oxygen is used
For energy generation and
carbon dioxide gets absorbed
By blood and reaches to heart

13. From here heart pumps this blood
to lungs where carbon dioxide gets
diffused to alveoli
And to get oxygen alveoli needs to
be emptied and that where
exhalation comes …

14. In this process sternum moves
inwards and diagram moves
upwards, these movements
pressurize the gases out the lungs
through nostrils
