How does our body get what is needed to make energy in every cell?

• Our body uses the food we eat to make energy. We digest the food by mixing it with enzymes to break it down into sugars which get absorbed by the intestines and released into the bloodstream.
• We use the energy of the sun to make sugars out of carbon dioxide from the air and water.
• When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, into which your lungs expand to let food into the body and its cells.

Which example best shows structures that make up the Digestive System in the human body? 

• Lungs, Heart, Arteries
• Brain, Spinal Cord, Nerves
• Stomach, Intestines, Esophagus
• Nose, Lungs

What is the Circulatory System's main function?

• Produces Oxygen
• It's John Cena!
• Transportation of Nutrients
• Converting energy out of food

Which pair of systems work together to bring in oxygen into the body and deliver it to the cells?

• Muscular System, Skeletal System
• Circulatory System, Respiratory System
• Nervous System, Respiratory System
• Digestive System, Circulatory System

How does the Respiratory System filter oxygen out of the air?

• When we inhale air, our windpipe filters the air, which leads it to our lungs. In the lungs, oxygen is moved into the bloodstream and carried to where it's needed while red blood cells collect the CO2 and bring it back into the lungs, where it is exhaled.
• It doesn't, when we breath, we need both the oxygen and carbon dioxide.
• When we breathe in, the air goes down the esophagus and into the stomach where it expands and little hairs inside split the gases and take in the oxygen. When we exhale, the carbon dioxide travels back up the esophagus and out the mouth or nose.

Which of the following is NOT an example of human body waste?

• Carbon Dioxide
• Excrement
• Blood
• Urine

The following are ways that humans eliminate body waste EXCEPT?

• Any left over solid parts of the food after digestion move into the large intestine. The scientific word for this matter is excrement or feces. The entire trip from mouth to rectum can take 24 hours.
• When we eat food, it goes down this tube called the tubiolous. The inside of the tube absorbs the energy from the food and once there is no more energy, the food gets expelled out the anus.
• When we urinate, our kidneys remove toxins from our blood to produce urine, which trickles down to the bladder. I stays in that container until it is ready to leave the body.
• When we inhale air, our windpipe filters the out air we need and gets transferred to our lungs. Red blood cells collect the CO2 and bring it back into the lungs, where it is exhaled.

How does the Respiratory System deliver oxygen to different parts of the body?

• Inhaling carbon dioxide
• Breathing
• Circulation

Fill in the blanks: After chewing, the food is swallowed and passes down the ________ to the ________.

• Esophagus, Stomach
• Wind Pipe, Esophagus
• Salivary Glands, Esophagus
• Root Canal, Stomach

What is responsible for picking up the oxygen in the lungs and carrying it to all the body cells that need it?

• White Blood Cells
• Red Blood Cells
• Veins
