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
