The respiratory system brings oxygen into the body and removes carbon dioxide. It includes the nose, pharynx, larynx, trachea, bronchi, bronchioles, and lungs. The circulatory system transports blood throughout the body using the heart, arteries, veins and capillaries. It has two circuits - pulmonary and systemic. Diseases can affect both systems like asthma, pneumonia, anemia and atherosclerosis.

1. Respiratory System and
Circulatory System

2. What is Respiratory System
• The human respiratory system is a
series of organs responsible for
taking in oxygen and expelling
carbon dioxide. The primary organs
of the respiratory system are lungs,
which carry out this exchange of
gases as we breathe.

3. Respiratory System
• Organs of the respiratory system
• Nose/Mouth Bronchi
• Nasal Cavity Bronchioles
• Pharynx Alveoli
• Epiglottis Pleura
• Trachea Lungs
Lobes

4. Nose
• Brings air into the body
• Nasal hair in nostrils trap dust
Nostrils- the two openings of the nose the filters the air
we breathe.

5. Nasal Cavity
• Traps dust, pollen and other materials that were not
trapped by nasal hairs

6. Pharynx
• A muscular tube in the upper throat where the
warmed, moistened and filtered air moves
• Tube-like passageway used by food, liquid, and air

7. Epiglottis
• At the lower end pharynx is a flap of tissue called
epiglottis closes the entrance to the rest of the
reparatory system when you swallow.

8. Trachea
• Air- conducting tube
• Connects the larynx with the bronchi
• Lined with mucus membranes and cilia
• Contains strong cartilage rings

9. Bronchi
• Tiny Branches of air tubes in the lungs
• Connect bronchi to alveoli

10. Bronchioles
• Tiny branches of air tubes in the lungs
• Connect bronchi to alveoli

11. Alveoli
• Alveoli are tiny sacs within our lungs that allow oxygen
and carbon dioxide to move between the lungs and
bloodstream.

12. Pleura
• The pleura refers to the 2 membranes that cover
the lungs and line the chest cavity.

13. Lungs
• The lungs are a pair of breathing organs located with
the chest which remove carbon dioxide from and
bring oxygen to the blood.

14. Lobes
Right lung has 3 lobes Left lung has 2 lobes
Right superior Left superior
Right inferior Left inferior
Right middle

15. Parts of Respiratory System

16. Diseases in Respiratory System
• Asthma- a respiratory condition marked by spasms in the
bronchi of the lungs, causing difficulty in breathing. It usually
results from an allergic reaction or other forms of
hypersensitivity.

17. • Lung Cancer
• Lung cancer is the uncontrolled growth of abnormal cells
that start off in one or both lungs; usually in the cells that
line the air passages. The abnormal cells do not develop
into healthy lung tissue, they divide rapidly and form
tumors.
• Pneumonia
• lung inflammation caused by bacterial or viral infection, in
which the air sacs fill with pus and may become solid.
Inflammation may affect both lungs

18. Circulatory System
• The system that moves blood throughout the body. The
circulatory system is composed of the heart, arteries,
capillaries, and veins. This remarkable system transports
oxygenated blood from the lungs and heart throughout the
body via the arteries.

19. Main Parts of Circulatory System
• Heart- a hollow muscular organ that pumps the blood through the
circulatory system by rhythmic contraction and dilation. In vertebrates there
may be up to four chambers (as in humans), with two atria and two
ventricles.
• Blood Vessels- a tubular structure carrying blood through the tissues and
organs; a vein, artery, or capillary.
• Blood- the red liquid that circulates in the arteries and veins of humans and
other vertebrate animals, carrying oxygen to and carbon dioxide from the
tissues of the body.

20. Two circuits of the cardiovascular system
Pulmonary Circuit
• Carries the deoxygenated blood into the lungs
Systemic Circuit
• Delivers the oxygenated blood to the tissues

21. Four Chambers of Heart
• Atria- each of the two upper cavities of the heart from which
blood is passed to the ventricles. The right atrium receives
deoxygenated blood from the veins of the body; the left atrium
receives oxygenated blood from the pulmonary vein.
• Ventricles- is one of two large chambers that collect and expel
blood received from an atrium towards the peripheral beds
within the body and lungs. The atrium (an
adjacent/upper heart chamber that is smaller than a ventricle)
primes the pump.

22. Valves
• that control blood flow to and from the heart

23. 3 Main Blood Vessels
• Arteries- which carry the blood away from the heart
• Capillaries- which enable the actual exchange of
water and chemicals between the blood and the
tissues
• Veins- which carry blood from the capillaries back
toward the heart.

24. 4 Major Components of blood
• Plasma- surrounds the blood cells and helps transport C02 and metabolic
products.
• Red Blood Cell- The blood cells that carry oxygen.
• White Blood Cell- One of the cells the body makes to help fight infections.
• Platelets- cells that come together help the body from bleeding

25. Disease in Circulatory System
• Anemia is a condition that develops when
your blood lacks enough healthy red blood
cells or hemoglobin.
• High blood pressure is a common condition
in which the long-term force of the
blood against your artery walls
is high enough that it may eventually cause
health problems, such as heart disease.

26. • Leukemia is a cancer that affects the
blood and bone marrow where blood cells
are made.
• Atherosclerosis is a disease in which
plaque builds up inside your arteries
