What are veins?
What is blood vessels that carry blood back to the heart
100
More than half of any given sample of blood is made up of a pale yellowish liquid called
What is plasma
100
Our automated gatekeepers job the epiglottis is to do what?
What is make sure that the larynx is opened so when you breathe air can pass through
100
What do bronchial tubes do?
What are tubes in lungs that carry air
100
How many chambers does the human heart have?
What is 4
200
What are arteries?
What is blood vessels that carry blood away from the heart
200
Within the plasma there are three main types of cells?
What is red blood cells, white blood cells, and blood platelets
200
The air leaves the larynx and travels to where? And then onto where?
What is the trachea, and onto one of the lungs via left or right primary bronchus
200
How many bronchial tubes are there in the average lung?
What is about 30,000
200
What are the names of the four chambers?
What is left atrium, left ventricle, right atrium, right ventricle
300
What are capillaries?
What is tiny, thin walled blood vessels that allow the exchange of gases and nutrients between the blood and the cells and are located between arteries and veins
300
What do red blood cells do? What do they contain? How long do they live? Where are they produced?
What is transport oxygen from lungs to tissues, contain hemoglobin, 80-120 days, made in bone marrow
300
How is air pushed into and out of the nasal cavity, pharynx, larynx, trachea, and lungs? What is the most important? What does this do to your lungs?
What is few skeletal muscles and the most important is the diaphragm. When diaphragm contracts it pulls the nearby lungs with them causing the. To expand.
300
At the end of the tubes there are tiny sacs. What are they called? How many of them are there?
What is alveoli, and 300 million
300
What signals the right atrium to contract
What is the sinoatrial node "pacemaker"
400
Do all veins always carry deoxygenated blood?
What is most of the time but not always. There are some exceptions?
400
What percent of blood do white blood cells make up? What is their job?
What is about 1 percent. They produce chemicals called antibodies which are released into blood to fight the pathogen
400
When you exhale air where does it pass through? Also what important item is in there that we need to communicate?
What is larynx and the vocal cords
400
Where does most of the action in the lungs take place? What happens?
What is the alveoli, the carbon dioxide gets dropped off and oxygen gets picked up. Then alveoli sends the cd back up the chain and out the mouth
400
Describe the flow of blood through the 4 heart chambers describing all the parts
1. What is sinoatrial node sends signal to right atrium, it contracts. 2. Blood goes from atrium to right ventricle. 3. Ventricle contracts pushing deoxygenated blood into the pulmonary trunk. 4. It then splits into the pulmonary arteries. 5. Those arteries send the deoxygenated blood into the capillaries in both lungs. 6. Here it releases carbon dioxide and picks up oxygen and turns into oxygenated blood. 7. It goes to the pulmonary veins and dumps into left atrium. 8. Contracts and sends blood to left ventricle. 9. Then it gets sent to the aorta or descending aorta. Depending on which part of body it's going to
500
How long would the average blood cells be if we strung them all together? And how long does it take for a single drop of blood to leave heart and return?
What is 90,000 miles and one minute
500
What are the smallest cells in your blood? What process do they aid in? What are the three steps to that process?
What is platelets, blood clotting, 1. The smooth muscles in injured cell contract to make hole as small as possible, 2. The platelets clump together and stick to the edges of the injury, 3. Coagulation- chemicals work together to transform certain proteins in the blood plasma into threadlike protein called fibrin which forms a tight web to seal off injury
500
What is a xylem? And how can it be compared to the human respiratory system?
What is it transports water from roots to entire plant. It is the plats transport system. Our is the circulatory system
500
Describe what happens in the lungs with the disease emphysema?
What is the alveoli become enlarged and merge together. So there are much fewer alveoli and this results in much less oxygen transfer to cells in body. Results in shortness of breath, wheezing, and difficulty breathing
500
All arteries carry oxygenated blood?
What is as a general rule most do but not all
