Human body systems
Transcript of Human body systems
1. Adults have 206 in there body.
1. Each day, 2,000 gallons of blood travel many times through about 60,000 miles of blood vessels that branch and cross, linking the cells of our organs and body parts.
1.Oxygen is the most important for keeping us alive because body cells need it for energy and growths.
1.When you do eat, the saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow.
1. Both the brain and the spinal cord are protected by bone the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae.
Human body systems
Your heart does not look like this in real life.
2. Your ribcage protects your organs like heart, lungs and liver.
3. Total amount of bones in your feet and ankles is 52.
4. You have 12 pair of ribs.
5. Your skull is a lot like the ribcage but it protects your brain.
2. More than 20 million people in the United States have asthma
3.Long-term smoking often causes emphysema.
4.Lung cancer is a leading cause of death in the United States and is usually caused by smoking cigarettes.
5.Babies born prematurely may not have enough surfactant in the lungs.
2. When your food has entered the esophagus, it doesn't just drop right into your stomach.
3. The stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces.
4. If you stretched out an adult's small intestine, it would be about 22 feet long.
5.And the leftover waste parts of the food that your body can't use goes on to the large intestine.
1. Smooth muscles can found in the bladder.
2. You'll find smooth muscles at work behind the scenes in your eyes, too.
3.Skeletal muscles come in many different sizes and shapes.
4. Facial muscles don't all attach directly to bone like they do in the rest of the body.
5. Your tongue is actually made of a group of muscles that work together to allow you to talk and help you chew food.
2. The heart is the key organ in the circulatory system.
3. It supplies oxygen and nutrients to our bodies by working with the respiratory system.
4. Approximately 8 out of every 1,000 newborns have congenital heart defects ranging from mild to severe.
5. In the lungs, the branches divide further into capillaries.
2. M.S. can effect some parts in the nervous system.
3. The human brain weighs just 3 pounds.
4. The brain has billions of cells called neurons.
5. If something frightening happens, the sympathetic nervous system makes the heart beat faster so that it sends blood more quickly to the different body parts that need it.
The brain is the control center of your body.
Tobacco will cause less blood and oxygen flows to your muscles.
You need to eat or you will become ill and die.
Thank you so much for watching.
The skeleton is important for the structure of your body because it stands you up right and makes your body pretty much the shape it is. If it was not for the skeleton you would be a big blob.
Your brain communicates with other parts of the body by sending signals through your nerves to the part it wants.
You move with the muscles by the tissue that that contracts and and relaxes, making movement possible.
When you inhale oxygen to supply the cells of your body and exhale carbon dioxide that the cells give off as waste. That is what happens when you take a deep breath.
Blood goes though out the body with the help of arteries.
Blood runs in the capillaries protected by a thin membrane. The nutrients pass the membrane to get into the blood, and the blood can deliver the nutrients to where ever needed, usually passing through liver. This happens in the intestines after primary digestion and continues into the colon.
