Respiration?

• An important system in which oxygen and carbon
  dioxide are exchanged between cells, blood, and
  air in the lungs.

5
Main Job?

• It is a simple task, to exchange oxygen and
  carbon dioxide.
• However, without oxygen, cells lose much of their
  ability to produce ATP
• ATP is needed to synthesize new molecules, pump
  ions, and carry nerve impulses.

-Your body keeps up with your needs, like
running, the muscle cells need more oxygen to do
what you want.

Inhaled, they fill up with oxygen and other
gases, then as a gas waste, carbon dioxide is
exhaled.
This allows the volume of the chest cavity to
expand, therefore allowing us to breath, thus air
rushing into the passages.
The windpipe that serves as a air passage to the
lungs.
7
Into the Lungs
A passage way for the air to get into the alveoli
and undergo gas exchange.
Millions of tiny air sacs clustered like grapes
are wrapped around a delicate layer of thin
capillaries in which gas exchange begins.
8
Gas Exchange-Step 1
Inhaling, oxygen is diffused into the capillaries
when carbon dioxide is diffused oppositely when
exhaling.
9
Gas Exchange-Step 2
Deoxygenated blood is passed through the
capillaries and when the oxygen inhaled arrives
at the alveoli, the oxygen is then grabbed by the
blood. Oxygen and carbon dioxide pass through two
layers, the epithelium, and the wall of capillary.

Protective Procedures
1. To keep the lungs clean important cells called
the cilia is found in the lining of the trachea
and trap unwanted particles of dust or smoke.

Protective Procedures

• 2. In the nose there are tiny hairs trap bacteria
  from getting in. The lymphatic system produces
  mucus where it is formed to trap bacteria when
  breathing. Major role in immune system as well.

Protective Procedures

• 3. Mucus keeps the passageways and pharynx
  (throat) warm and moistened so that air can be
  filtered perfectly.

14
Protective Procedures

• 4. As a waste basket, cilia sweep the mucus and
  dirt to the pharynx or throat to be swallowed or
  spit out.

Human vs. Animal
Human Respiratory System
Blue Jay
There is one small difference, birds need more
air sacs for flight. When taking off, birds
require more strength to hover, when in the air
they require less from lifting winds, but with
the high altitudes it is hard to breath,
therefore more air sacs.
