| alveoli | air sacs in your lungs
🗑
|
||||
| pleural membrane | surrounds your lungs
🗑
|
||||
| Where does cellular respiration take place in the cell? | mitochondria
🗑
|
||||
| What is the primary job of cellular respiration? | to release ENERGY from digested nutrients (food).
🗑
|
||||
| What does it mean if food releases more heat when burned? | It contains(has) more calories.
🗑
|
||||
| What are the ingredients (inputs) of cellular respiration? | nutrients (glucose), oxygen
🗑
|
||||
| What are the products (outputs) of cellular respiration? | energy (ATP), carbon dioxide, water
🗑
|
||||
| Examples of homeostasis (respiratory and circulatory system) | more glucose is burned if you body needs more energy and your breathing rate increases during exercise
🗑
|
||||
| Path of oxygen when you breath | mouth/nose, trachea, bronchi, bronchioles, alveoli, bloodstream
🗑
|
||||
| vital capacity | the amount of air that person can exhale after a deep breath. *remember we measured this in lab
🗑
|
||||
| What happens when you you inhale? | diaphragm moves DOWN, ribs go out, volume in chest cavity increases, and air pressure in lungs DECREASES
🗑
|
||||
| what happens between the alveoli and capillaries? | oxygen and carbon dioxide gas exchange
🗑
|
||||
| Can you ever remove all the air from your lungs? | no, you always have some remaining. *remember the sponge lab?
🗑
|
||||
| Bromthymol Blue (BTB) checks for the presence of what substance? | carbon dioxide
🗑
|
||||
| why do you exhale more carbon dioxide? | during cellular respiration, cells produce carbon dioxide as waste.
🗑
|
||||
| What is the aorta? | the "superhighway" that carries oxygenated blood out of the heart and UP into the body
🗑
|
||||
| which way does blood flow through the left ventricle? | flows down. *know you heart diagram
🗑
|
||||
| which way does blood flow through the right ventricle? | flows up. *know your heart diagram
🗑
|
||||
| flaps of tissue between heart chambers | valve
🗑
|
||||
| Where does blood from the right atrium come from? Which way does the blood flow? | vena cava and it flows down to the right ventricle.
🗑
|
||||
| Pulmonary veins bring oxygenated blood from the lungs back to the... | left atrium, left ventricle and aorta (then to the body)
🗑
|
||||
| red blood cells | carries oxygen to body cells
🗑
|
||||
| white blood cells | protects the body against disease
🗑
|
||||
| platelet | aids in clotting of blood after a cut
🗑
|
||||
| plasma | liquid part of the blood
🗑
|
||||
| is the human circulatory system opened or closed? | closed because there is no entry or exit
🗑
|
||||
| how many chambers in the heart? | four chambers
🗑
|
||||
| Which ventricle is stronger? | the left ventricle is stronger because it pumps blood to the whole body instead of just the lungs.
🗑
|
||||
| why do body's cells come back to the heart with less oxygen? | the body cells use oxygen for respiration
🗑
|
||||
| what happens to your blood pressure, when arteries build up with plaque? | the blood pressure increases
🗑
|
||||
| what are some risk factor for high blood pressure? | excess cholesterol, obesity, smoking
🗑
