Bio 103 final Questions with complete solutions
gills - ✔✔organs that exchange oxygen and carbon dioxide with water through ventilation of water
through fibrous gills
uses counter current exchange
Circulatory systems link exchange surfaces with cells throughout the body by - ✔✔diffusion of
materials between cells but only short distances
Or circulatory system that has a fluid that takes materials from the world into the body
open circulatory system - ✔✔filled with the fluid hemolymph to bathe organs directly
what does a circulatory do - ✔✔connects the fluid that surrounds cells with the organs that
exchange gases, absorb nutrients, and dispose of wastes
closed circulatory system - ✔✔series of vessels filled with blood distinct from interstitial fluid
Arteries - ✔✔carry blood away from the heart to the capillaries
veins - ✔✔Blood vessels that carry blood back to the heart from the capillaries
two cambers of the heart - ✔✔blood enters through the atrium and is pumped out through a
ventricle
Single circulation - ✔✔blood leaves the heart and passes through two capillary beds before
returning, one being gills and the other in the body
double circulation - ✔✔a circulatory system consisting of separate pulmonary and systemic circuits,
in which blood passes through the heart after completing each circuit of going through capillaries
endothelium - ✔✔innermost lining of blood vessels, very smooth to minimize resistance
Differences between arteries and veins - ✔✔Arteries have thicker walls because of high pressure of
blood
, while veins have valves to keep blood from going back
pressure drops most in the... - ✔✔capillary beds with the most area of vessels
blood travels through one cell at a time to exchange materials better
lymphatic system - ✔✔Composed of a network of vessels, ducts, nodes, and organs to return fluid
leaks from capillary beds. Provides defense against infection.
lymph nodes - ✔✔Bean-shaped filters that cluster along the lymphatic vessels of the body. They
function as a cleanser of lymph as wells as a site of T and B cell activation
when fighting sicknesses they swell
partial pressure - ✔✔pressure exerted by a particular gas in a mixture of gases
reptile gas exchange - ✔✔need large moist respiratory surface on the skin and some have lungs
tracheal system for insects - ✔✔network of branching tubes putting oxygen directly into body cells
separate systems between respiratory and circulatory
lungs - ✔✔inhalation and exhalation to collapse and explanations of surface area of where gas
exchange takes place
rib muscles and diaphragm contract
alveoli - ✔✔tiny sacs of lung tissue specialized for the movement of gases between air and blood
how birds breath - ✔✔very efficient
air goes only one way passing through posterior air sac then lungs then anterior air sacs
two cycles of inhalation and exhalation
hemoglobin - ✔✔An iron-containing protein in red blood cells that reversibly binds to 4 molecules of
oxygen.
