The Blood
What colour is plasma?
Yellow
Order these from smallest to largest. Veins, capillaries and arteries.
Capillaries, veins and arteries
Describe how the windpipe works in the respiratory system.
Then, it goes into our trachea, also know as a windpipe. The trachea is next to the esophagus. Instead of going into the stomach, the trachea sends air into the lungs.
What is the role of white blood cells?
To fight off sickness
The most common form of heart disease?
Coronary Heart Disease
Do red blood cells carry oxygen towards or away from the heart from the body?
Away from the heart.
Describe how the bronchus works in the respiratory system.
The bronchus is like the trunk of a tree. It is the widest part of the branch system in our lungs. The bronchus divides into main branches. The branches of the bronchus are lined with cartilage to hold their shape.
There is mucus in this part of the lung, too. Mucus is pushed around by little hairs. The mucus helps to clear the lungs of dirt and germs that may get into your lungs. That is why when you are sick there is more mucus in your lungs.
What is the role of platelets?
Clot your blood to help close and heal a wound.
What is deep vein thrombosis?
When a blood clot forms in a deep vein in the body.
What is the diaphragm? How does it help us breathe?
The diaphragm is a muscle underneath the lungs that pulls and contracts which allows us to inhale and exhale.
What are the 3 vessels that transfer blood around your body?
Capillaries, Veins and Arteries.
Describe how the bronchioles work in the respiratory system.
When you need more oxygen in your body, like when you are exercising, your bronchioles can stretch and become wider so more oxygen can get to your body. They can shrink when you are breathing in bad or polluted air.
What are the 4 ingredients that make up the blood?
-Plasma -White Blood Cells
-Platelets -Red Blood Cells
what is the purpose of the valves in our heart?
They act like doors that open and close to make sure that blood continues to flow in the correct direction through the heart.
What is Asthma? (Describe what it is and how it affects people who have this disease)
A disease that affects the lungs. Sensitive lungs that over react to certain problems. (asthma attack)
They stop breathing normally and they start to wheeze. They struggle to breathe, have shortness of breath, begin coughing a lot, and have a tight feeling in their chest.
Caused by "bad" air. Pollution, allergens, smoke etc.
Panic and try to stop the bad air from entering the lungs. The stretchy walls of the bronchioles swell and narrow. They produce more mucus to try and wash away the bad air.
Why can plaque build up in your arteries be dangerous?
when plaque builds up on the artery walls, which blocks the blood flow to the heart. If a clot forms and travels to the brain, this is called a stroke. If the buildup prevents oxygen- rich blood from getting to the heart, this will cause a heart attack.
Describe how the alveoli works in the lungs.
air sacs at the end of your lungs. These air sacs take the oxygen from the air and send it to the blood through the capillaries. The alveoli and the capillaries are connected through a very thin wall that lets the oxygen move between them.
What do red blood cells deliver throughout the body?
Oxygen and nutrients.
What is it called when blood leaks back into the heart the wrong way through the valves?
Regurgitation
Describe the 4 different elements (parts) of the lungs/ respiratory system.
1. Trachea/ Windpipe
2. Bronchus
3. Bronchioles
4. Alveoli
Describe how blood circulates through your body. (Think about Billy Ruban)
Blood is constantly circulating through the body. Red blood cells pick up carbon dioxide from our body and go to the heart to get pumped into the lungs. Once in the lungs, they drop off the carbon dioxide exchange it for oxygen. Then they go back into the heart, to get pumped back into the body. The process repeats...
Describe the process of a breath. (Describe what happens when we take a breath in the correct order of steps.)
We breathe in air through our nose/ mouth which goes through the trachea and then into the lungs. The air enters the bronchus (the big tree trunk like branches) and then to the bronchioles (the smaller branches). The air then goes into the alveoli, which take the oxygen from the air (breath) and send it through the capillaries.
