Most models use 2-liter soda pop bottles to model the lungs, I prefer the smaller, cheaper plastic cups in a classroom setting. Each breath begins with a contraction of the diaphragm, a dome-shaped sheet of muscle that lies just below the lungs. When you inhale, your diaphragm contracts, or flattens downward. This contraction creates a lower pressure in your chest cavity. Normal outside air pressure forces air through the nose and mouth, down the trachea and into the lungs. When you exhale, your diaphragm relaxes, increasing pressure on the lungs and forcing air out of the body. Materials: Flexible straws Clear plastic cups (7, 8 or 9 oz) Small balloons Large balloons Scissors Modeling clay Scotch tape Rubber bands Steps 1. Make a hole about the diameter of a straw in the bottom of the plastic cup with the scissors 2. Cut a 5 cm inflexible section of a straw 3. Make a small slit in the elbow of another straw 4. Insert the 5 cm piece of straw into the slit to form a "Y". Use some modeling clay and tape to make the joint airtight. 5. Tape the small balloons to each end of the diagonal segments of the "Y". Make sure these connections are airtight. 6. Thread the vertical (long) leg of the "Y" through the hole in the cup and seal with clay. 7. Cut the neck off the large balloon. Cover the open end of the cup with the rest of the balloon, use rubber band and tape to secure it. In this model, the cup is the chest cavity, the straws are the bronchi and trachea, the small balloons are the lungs, and the big balloon is the diaphragm. Manipulating the large balloon (pulling it out and pushing it in) will cause the small balloons to inflate and deflate, modeling breathing.
stem cells can be used to create functioning organs , such as lungs, hearts etc.
The respiratory system is the system in your body make of choclate and bricks
NO!
lungs?
lungs
Several systems and organs are excretory: the skin, the lungs and the kidneys.
cells make up tissues tissues make up organs organs make up body systems
The lungs are the organs that bring oxygen into your body, and your heart is the organ that pumps this oxygen around the body via the blood. So it would make sense for two organs that needed to work together to be close to each other. In addition, they are two of the most important organs and are in the torso of your body along with most of the other important organs such as the liver, stomach, etc. This means in a life threatening situation you can protect your vital organs easier because they are in the same area.
The difference between cells, tissues, organs, and body systems are that many cells make tissues, many tissues make organs, and many organs make body systems.
Exercise will cause your body to demand more oxygen than your lungs can process at any given time. Your lungs don't get tired, they just try to catch up with the demand of your muscles and organs for oxygen.Your lungs can not get fatigued; they are a passive part of the body that uses diffusion to get oxygen to your blood. Your diaphragm muscles are the things that make your lungs fill up with air and expel the air.Basically, excercise makes your body tired, and your lungs need more air.
A body.
The organs that make up the respiratory system are the mouth, nose, Trachea, Lungs and bronchial tubes.
you sweat and breath hard to excrete liquid
