| 1081641901 | do small cellular species need an internal transport system? | nope they just diffuse everything in and out of their cell membrane | |
| 1081641902 | what do transport systems move? | nutrients, waste, and water. | |
| 1081641903 | how do animals move substance in their transport systems? | with a heart that acts as a pressure source to pump the system. | |
| 1081641904 | in plants what does the xylem do? | moves water and substance up from the roots. | |
| 1081641905 | in plants what does the phloem do? | moves sugars made in photosynthesis through the plant. | |
| 1081641906 | do the xylem and phloem use a pump like animals? | nope the movement of these pathways depend on water potential. | |
| 1081641907 | study pig heart pictures | sorry can't put picture on here. | |
| 1081641908 | do the left and right atriums fill with blood at the same time? | yes | |
| 1081641909 | what is the valve between atrium and ventricle on the right side of the heart? | the tricuspid valve. | |
| 1081641910 | what is the valve between the atrium and ventricle on the left side of the heart? | bicuspid valve | |
| 1081641911 | what is the sound made when the bicuspid valve closes? | a lub sound | |
| 1081641912 | what is the valve from the right ventricle to the pulmonary artery? | the pulmonary valve. makes a dub sound | |
| 1081641913 | what is the valve between the left ventricle and the aorta? | aortic valve | |
| 1081641914 | systolic pressure | the top part of blood pressure.measure of force of blood against brachial artery wall as left ventricle contracts. | |
| 1081641915 | diastolic pressure | bottom part of blood pressure. measure of force of blood against brachial artery as left ventricle relaxes. | |
| 1083438475 | What parts of the heart are associated with electrical events that occur there. | sino-atrial (SA) node atrio-ventricular (AV) node Purkinje fibers | |
| 1083438476 | What does the SA node do? | it is located in the right atrium and when the SA node depolarizes the an electrical current spreads out from the node and stimulates the muscles of the atria to contract. And also spreads to the AV node. | |
| 1083438477 | What does the AV node do? | The AV node is located between the right atrium and ventricle and once the elcetrical signal from the SA node reaches the AV node it then passes the signal even farther on to the Purkinje fibers. | |
| 1083438478 | What doe the Purkinje fibers do? | The Pukinje fibers are located at the bottom of the heart near both ventricles. Once the electrical signal has reached these fibers they contract the ventricular muscles. | |
| 1083438479 | as the ventricles _________ the atria __________. | depolarize, repolarize | |
| 1083438480 | What can be seen by an EKG tracing. | depolarization of atria and depolarization and repolarization of ventricles. | |
| 1083438481 | what are the order of the bumps on the picture. | p wave(small) QRS complex (large) T wave (small) | |
| 1083438482 | what does the P wave show? | the depolarization of the atria | |
| 1083438483 | what does the QRS complex show? | the depolarization of ventricles, but also the repolarization of atria occur at this same time. | |
| 1083438484 | what does the T wave show? | the repolarization of ventricles. | |
| 1083438485 | what can you find when you measure between the two QRS peaks. | your heart rate. | |
| 1083438486 | what types of animals did we study their transport systems? | angiosperms | |
| 1083438487 | what are the two types of angiosperms we studied? | monocots= grass in your lawn, corn, wheat, onions, and irises. eudicots= oks. maples, basswoods, roses, clover, and tomato. | |
| 1083438488 | what three things distinguish the differences between monocots and eudocots? | Number of embryonic leaves(M=1:E=2) leaf venation(M=parallel:E=netted) flowering plants(M=multiples of 3:E= multiples of 4/5) | |
| 1083438489 | what monocot is named zea mays, we studied this in lab. | corn | |
| 1083438490 | what are the portions of the corn root | Epidermis, cortex, endodermis, pith, phloem, and xylem.and has a stele(the central cylinder that holds xylem and phloem) | |
| 1083438491 | What is the herbaceous eudicot root we looked at in lab? | Ranunculus( buttercup) | |
| 1083438492 | what are the parts of the Ranunculus root we drew. | Stele, cortex, epidermis, endodermis, phloem, and xylem. | |
| 1083438493 | which plant has the X shaped xylem? | buttercup root.( ranunculus) | |
| 1083438494 | Is there a clear stele in the monocot stem of zea mays? | no. | |
| 1083438495 | what are the parts of the stem of zea mays did we label? | vascular bundle, ground tissue, epidermis, phloem, and xylem. | |
| 1083438496 | Does the herbaceous eudicot stem have a stele? | no | |
| 1083438497 | what parts of the herbaceous eudicot stem did we label? | vascular bundle, pith , epidermis, cortex, phloem, and xylem | |
| 1083438498 | What was the name of the woody eudicot we studied in lab? | tilia( basswood) | |
| 1083438499 | what parts of the basswood (tilia) stem did we label? | phloem and xylem | |
| 1083438500 | In trees what is farther inside the xylem or phloem? | the xylem. | |
| 1083438501 | How does water enter and leave the cell? | through the stomata. | |
| 1083438502 | what controls the size of the stomata? | two guard cells. | |
