| Question | Answer |
|---|---|
| In mollusk blood flow is _____ in gills to water | counter current |
| This system distributes nutrients waste and oxygen | circulatory system |
| Gases are transferred by ______pigments | respiratory |
| _______are iron based in most animals | hemoglobin |
| _______are copper based and blood is green | hemocynain |
| Blood flow away from heart | artery |
| Blood flow towards heart | vein |
| Any blood flow is always | one way |
| The finest connection between veins and arteries are the | capillaries |
| These are 1 cell layer thick one red blood cell at a time | capillaries |
| 1 cell layer is very leaky and leakage is channeled back by the | lymph system |
| The cavity that forms the chamber where hemolymph is circulated | blastocoel |
| ____is more complex than human blood but thinner accounts for 20 -40% of weight | hemolymph |
| ______system blood is more concentrated and is 5 to 10 % of weight | closed |
| _____weight makes you more mobile | reduced |
| ________ the valve located between the right atrium and right ventricle | tricuspid valve |
| Chordae tendinae are guide wires string anchored to ______ | papillary muscle |
| Papillay muscle keeps your valve from being | blown open |
| ________artery leaves right ventricle towards lungs | pulmonary |
| _____semilunar valve in pulmonary artery | pulmonic |
| Fuctional unit of the longs | alveoli |
| There are _____cell layers in lungs that pick up o2 and drops Co2 | 2 |
| ______veins pump blood Oxy blood back to heart in left atrium | pulmonary |
| ______valve or mitral valve is between the left atrium and ventricle | bicuspid |
| Blood leave left ventricle and goes out the ______semilunar valve | aortic |
| Blood leaves heart and goes everywhere but ______even back to the heart | the lungs |
| _____little holes above _____semi lunar valve feed blood to the coronary arteries | 2 & aortic |
| These have 2 chamber hearts with no separation of O2 blood and non O2 blood | fish |
| Amphibians have ____ chamber hearts and use skin for respiratory as well | 3 |
| As _____increases O2 needs to be separated for efficiency | metabolism |
| Mammals have a ____that prevents mixing of blood | septum |
| Reptiles have a _____ chamberd heart that includes birds and mammals with high metabolism | 4 |
| A hole the fetus has in its atrium to bypass lungs- connects the two atria | Foramen ovale |
| ______is the first animal with a closed circulatory system | earthworms |
| The _______artery needs low pressure | pulmonary |
| The ________has higher pressure and is noticibaly thicker | left ventricle |
| Dinosaurs and some whales have______ because of their size | accessory hearts |
| ______ is to maintain body temp | a high heart rate |
| ________are the largest animal ever is elongated and dosent need high b.p. | blue whale |
| Faster metabolis__________ | lower life span |
| Gills can pull ____% O2 from water but water is too viscous and heavy to breath consistently | 2 |
| The more acidic hemoglobin becomes the _____effecient it is | less |
| If you lower the ph (more acidic) the _______O2 can be carried | less |
| They have metamerism (repeated body segments) but their digestive system is not | Phylum Annelida |
| They have a true ceolem and tissue lining their organs | Phylum Annelida |
| Phylum Annelida have hair like extensions made of chiatin called | Setae |
| They have a closed circulatory and aspire with gills or their skin | Phylum Annelida |
| They are diaechous or are hemaphodites that have sex with another | Phylum Annelida |
| They have a hydrostatic skeleton and have no hard structural components | Phylum Annelida |
| Have longintudial and circular muscle | Phylum Annelida |
| These are used to anchor Phylum Annelida to their substrate | Setae |
| Phylum Annelida class________means (few hairs) | class Oligocheta |
| Some or these are aquatic most are small but there is 9 foot species | class Oligocheta |
| Oligocheta have a ______ patch that secretes muscus to hold worms together during sex | clitellum |
| Prosomium is the _____ part of the worm and is not repeated | front mouth |
| The ____is not repeated as well | anus part |
| Oligocheta eat ________matter | decaying |
| Oligocheta use _______ to move food down their gut | peristalys |
| Oligocheta have a _______ that is a spiraling ridge in the gut used to increase absorbtion | typhlosole |
| Oligocheta have their verison of a | liver |
| _____cells in Oligocheta store glycogen like our liver | chlorogogue |
| Oligocheta have a _____that excrete excess calcium | calciferous |
| Aquatic forms of Oligocheta have…. | gills |
| _______are important economically because they till fertalize & put nutrients in soil to make it fertile | Oligocheta |
| ______estimated 1 acre had 50’000 worms and are making 18 tons of feces (castings) to fertilize land | Darwin |
