Resp. and Circ. Sys.
Respiratory and Circulatory Systems
| Term | Definition |
|---|---|
| nose | filters and warms air you breath |
| larynx | voicebox |
| trachea | windpipe |
| 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 |
