Big Idea: How do these systems work together?
STUDY WITH THESE FLASHCARDS
Digestive System: In charge of food.
1. Mouth- mechanical and chemical breakdown of food
2. Esophagus- movement of food to stomach
3. Stomach- stores and breaks down (both mechanically and chemically) food
4. Liver- helps break down fats, separates waste, and breaks down toxins
5. Small Intestine- completes chemical breakdown of food and absorbs nutrients
6. Large Intestine- absorbs salt and water and starts solid waste production (makes poop)
7. Rectum- stores solid waste until expelled from body
*Students will need to know the order that food travels through the digestive system, spell the organs correctly, and be able to write out the functions of each organ
Respiratory System: In charge of breathing.
1. Mouth- air enters and exits body
2. Windpipe (Trachea)- moves air to and from the lungs
3. Lungs- exchange carbon dioxide and oxygen
4. Aveoli- tiny air sacs in the lungs
Oxygen is needed for bones to grow, muscles to move, and food to digest (to name a few). Carbon
dioxide is the waste from bones growing, muscles moving, and food digesting. Oxygen comes in our bodies and carbon dioxide leaves it (plants are opposite). Oxygen and Carbon Dioxide are exchanged in the smallest part of the lungs, called the alveoli, by passing into and out of the blood stream.
When the body is in motion, it needs more oxygen to move. Therefore the quicker our muscles are moving, the more oxygen we need. You may notice how you start to breathe heavier when you increase your level of activity. The heavier breathing is so that your body can get more oxygen. Your heart, which pumps blood carrying the oxygen to your muscles will also work harder.

Did you know??
Circulatory System: Blood acts as a delivery system.
Blood flows through every part of the body dropping off Oxygen and picking up Carbon dioxide. Nutrients (from food) are also carried by the blood cells. Think of a blood cell as a boat, the blood stream as the river, and Oxygen/ Carbon Dioxide/ Nutrients/ Waste as the cargo. The heart acts as a pump to keep the "river" moving around the body. The heart has four chambers. The blood, very high in carbon dioxide waste, comes into the heart and gets pumped to the lungs to be exchanged for oxygen. The blood, now rich in oxygen returns to the heart to get pumped back out to the body. It creates a pattern: Heart, Lungs, Heart, Body (body meaning head, arms, legs, organs, etc.). Veins and arteries are the "highways" that blood travels through. Arteries (A-Away) brings blood away from the heart. Veins bring blood back to the heart.
Heart Disease: When the heart cannot work properly, it can severely affect other parts of your body.

Heart disease is when your heart cannot work properly and sometimes stops pumping. It is caused by blockages of plaque built up in the artieries that do not allow blood to go through. The heart is an organ too and needs oxygen to move. Therefore, when clogged arteries prevent blood from getting to the heart itself, it may cause part of the muscle to die. Similar to a stroke in the brain, the damaged heart muscle is known as a
heart attack. Scientists and doctors have developed ways to fix heart problems such as bypassing the clogged artery, essentially adding a new path for blood to get around.
Risk factors are habits or environmental conditions that can cause an individual to develop a particular disease. Some risk factors are voluntary, meaning the person chooses to do them, while others are nonvoluntary, meaning the person cannot control it.
Risk factors for Heart Disease include:
-Age (nonvoluntary)
-Race (nonvoluntary)
-Gender (nonvoluntary)
-Family history (nonvoluntary)
-Diet (voluntary)
-Exercise (voluntary)
-Smoking (voluntary) second hand smoke may be considered nonvoluntary
-Drinking (voluntary)
-Weight (voluntary)
*Students will need to explain voluntary choices one can make to reduce their risk of heart disease.
