CIRCULATORY SYSTEM
LOCATION
Both the Circulatory System and
Respiratory System are centered in
the chest, specifically at the heart!
CIRCULATORY SYSTEM
Major Function
➢MAJOR FUNCTION:
Transports material to and from cells
(nutrients, gases, wastes, and other
substances)
CIRCULATORY SYSTEM
Diagram and their functions HEART: To transport blood
throughout your body
VEINS: To transport blood that has
CO2 back to your heart
ARTERIES: Carry blood away from
your heart
CAPILLARIES: Enable oxygen, CO2,
and nutrients to move between your
Circulatory System and body
* Capillaries not shown in diagram
The Heart, Arteries, and Veins

BLOOD
BLOOD PURPOSE:
* To Deliver vital substances like oxygen, water, and
nutrients.
* Removal of dangerous wastes
* Contains/transports immune factors, contains
clotting factors
CIRCULATORY SYSTEM
Blood Components
RED BLOOD CELLS:
Carry Oxygen to the cells( from the lungs), and carry CO2 to the lungs. Contains Hemoglobin. Has no nucleus.
WHITE BLOOD CELLS:
Clean- up for the body, and immune responses to injury or infection. Contains Stem cells( in the bone marrow). Has a nuclei.
PLASMA:
Carries Red blood cells, White blood cells, Platelets, and other substances. Contains mostly water, and salt proteins (has one important protein: Albumin)
PLATELETS:
Clump together to form clots and scabs to stop bleeding and seal wounds. Contain cell fragments( bits of membrane bound cytoplasm). Made in the bone marrow.

CIRCULATORY SYSTEM INTERACTIONS
SYSTEM INTERACTION
Respiratory Delivers O2 to cells from lungs and drops off CO2 to the
cells from the lungs.
Digestive Absorbs and delivers digested nutrients to cells.
Excretory Filters cellular waste out of blood for removal.
Lymphatic Transports fluids and wastes.
Immune Transports antibodies and white blood cells throughout
the body.
Nervous The Vegas nerve controls heartbeat.
Endocrine Transports hormones throughout the body.
RESPIRATORY SYSTEM: Major Function
Takes in oxygen and removes carbon dioxide,
water, and other gaseous substances from the
body.
Respiratory System Diagram
1. Nasal passage : Brings in O2 to the lungs and filters air.
2. Lungs : Takes in oxygen
3. Larynx : Opening to the trachea, Epiglottis is the “flap” that opens and closes to allow only gases to pass, the vocal cords (glottis) produce sound
4. Trachea : Provides air flow for respiration
5. Bronchi : Transports air to the alveoli.
6. Bronchioles : Allows air to pass to the alveoli.
7. Alveoli : Transports oxygen to the blood stream.
The Breathing Process
Air enters the body when your diaphragm contracts.
Air passes through the nasal passage to be cleaned and warmed.
Air then passes through the pharynx to the trachea.
The trachea connects to the bronchi, there are two bronchi, one in the left and one in the right. The bronchi divides into smaller tubes, bronchoili, that end in tiny groups of cells that look like bunches of grapes, these are alveoli, where oxygen is absorbed and waste products expelled.
RESPIRATORY SYSTEM INTERACTIONS
❖ INTEREACTION WITH CIRCULATORY SYSTEM:
Takes in O2 for delivery to cells and removes CO2 brought from cells
❖ INTEREACTION WITH EXCRETORY SYSTEM:
Removes excretory waste gases
❖ INTEREACTION WITH NERVOUS SYSTEM:
Autonomic nervous system controls breathing
❖ INTEREACTION WITH MUSCULAR SYSTEM:
Diaphragm is the muscle that contracts and expands to control breathing
5 FUN FACTS ABOUT EACH SYSTEM
CIRCULATORY SYSTEM RESPIRATORY SYSTEM
❑ One drop of blood has millions of
red blood cells, each contains 250
million molecules.
❑ When and adults blood vessels are
laid out (end to end), they could
stretch over 62,500 miles.
❑ To pump blood- the heart contracts
tirelessly for more than 2.5 billion
times in an average lifetime.
❑ An average sized adult carries about
9 pints of blood.
❑ The aorta is the largest artery in
the human body.
o The pharynx is a part of the respiratory
system and the digestive system
o The trachea is also called the wind pipe.
o If the inner surface of the lungs would
spread out, it would be the size of half of
a tennis court.
o The air from a sneeze can reach a speed
of 100 miles per hour.
o The average person breathes in about 13
million cubic feet of air in a life time
