Structure of the Circulatory System Our circulatory system is
responsible to transport materials throughout our body. Just as with any highway system, larger blood vessels allow blood to travel faster and longer distances than smaller vessels.

Circulatory OrgansOrgan Function
Heart Pumps blood through blood vessels
Arteries Carries blood away from the heart (most with oxygen)
Veins Carries blood to the heart (most without oxygen)

Fun Fact:
Do you remember the last time you were frightened? How did your heart respond to the scare?
![Page 7: Structures of the Body. Explain This: Los Angeles, like most large cities, has a combination of freeways/interstates and local roads. Why?](https://reader036.vdocuments.mx/reader036/viewer/2022070407/56649e165503460f94b0044e/html5/thumbnails/7.jpg)
Fun Fact:
When you are frightened your body releases chemicals that speed up your heart rate. This is known as the fight-or-flight reaction. As your heart beats faster, your muscles receive more blood. As a result, your body has extra strength to react quickly.

Structure of the Respiratory System Unlike fish, our bodies are not designed
for underwater breathing! For this reason, scuba divers have to wear special equipment to breath under water.

![Page 11: Structures of the Body. Explain This: Los Angeles, like most large cities, has a combination of freeways/interstates and local roads. Why?](https://reader036.vdocuments.mx/reader036/viewer/2022070407/56649e165503460f94b0044e/html5/thumbnails/11.jpg)
Respiratory Organs
When we breathe in, oxygen travels through a series of tubes till it reaches the alveoli sacs in the lungs. There oxygen is exchanged with carbon dioxide from the blood. The carbon dioxide travels in reverse till it exits the body through the nose or mouth.

Fun Fact:
The air we breathe in is filled with pollution, microorganisms, and other things that can make us sick. How does the body protect itself?
![Page 13: Structures of the Body. Explain This: Los Angeles, like most large cities, has a combination of freeways/interstates and local roads. Why?](https://reader036.vdocuments.mx/reader036/viewer/2022070407/56649e165503460f94b0044e/html5/thumbnails/13.jpg)
Fun Fact:
Our body is designed to filter the air we breathe. The hair in our nostrils collect dust and other large particles that we breathe in. Smaller particles and microorganisms are trapped by the sticky mucus that follows.

Structure of the Muscular System The engine of a car is what allows the
car to move. Similarly, muscles allow us to move, usually by pushing or pulling against bones. It also provides protection to internal organs and allows for the movement of substances within the body. There are over 600 muscles in the human body.

Structure of the Digestive System The human body, as with a car, needs
fuel to function. When you eat food travels through a series of organs to break food down into usable energy.
![Page 35: Structures of the Body. Explain This: Los Angeles, like most large cities, has a combination of freeways/interstates and local roads. Why?](https://reader036.vdocuments.mx/reader036/viewer/2022070407/56649e165503460f94b0044e/html5/thumbnails/35.jpg)

Digestive TractOrgan Function
Mouth -Teeth grind food into smaller pieces-Saliva turns starches into sugars
Esophagus -Connects mouth to stomach-Peristalsis (muscle contractions) moves food down the tube
Stomach Muscle contractions churn food with gastric juices (acid and enzymes) into smaller pieces, forming a souplike mixture.

Digestive TractOrgan Function
Small Intestine -Intestinal juice, pancreatic juice, and bile break food down into molecules-Villi (small fingerlike projections) cover the intestinal wall and absorbs nutrients
Large Intestine -Absorbs water and minerals-Stores feces (solid waste from undigested food) until expelled

Fun Fact:
After eating a balanced meal, which contains plenty of fiber, it takes 24 hours for digestion to occur.
After eating a meal lacking fiber, it can take up to 96 hours for digestion to occur.

Excretory OrgansOrgan Function
Skin Expels salt, water, and other wastes when you sweat
Lungs Expels carbon dioxide and water when you breathe out
Kidney Filters excess salt, water, and urea (liquid wastes) from the blood and stores in bladder
Large Intestine Removes solid wastes (feces) from the body
Bladder Stores urine (filtered wastes from kidneys) until expelled through urination

Fun Fact:
The human body can survive with one functioning kidney! The surviving kidney would enlarge as it would need to work twice as hard to filter all the body’s blood.
