Flashcards in Lab Midterm Deck (81):
eye parts of microscope
keep at highest point
controls amount of light into condenser
focuses light on object
(4x,10x, 40x, 100x)
magnification of drawing (actual)
size of drawing/ size of object
diameter of field of view (drawing/ actual)
field of view / # fit across
cells combine to form
tissues combine to make
three main parts of cell
nucleus, cytoplasm, plasma membrane
flagella serves as
moves substances away from cell or along its surface
divides body into left and right halves( back and front)
oblique angle (not parallel to sagittal or transverse)
aqueous solution where solutes are dissolved or suspended
(conc. gradient) high to low
like water pass through polar membrane
do not diffuse across dialysis tubing
diffusion of water across SPM is
involves channel proteins (aquaporins)
why did the solution turn blue?
starch is a large molecule and when iodine and starch mix the solution turns blue
what happend to liver solution
began expand and "swell" because H2O2 is small molecule and can move into the cell wheere catalase breaks apart into H2O and O2. Then oxygen can not leave cell (non-polar).
water will move into cells 2,3,4 and will make them
if isotonic then the weight
bounces back and forth
sucrose can not
cross membrane(too big molecule)
net movement of water molecules
hypotonic and move from high to low conc.
complex/multicellular organisms are
comprised of many types of cells
no membrane bound organelles
membrane bound organelles (nucleus)
group of similar cells and intracellular substances
4 primary tissue types:
muscle, nervous, epithelial, connective (embryonic 5th...)
covers/lines all surfaces
squamous, cuboidal (urinary bladder)
connective tissue (4 types)
connect things, support, movement, protection, insulation, transport.
Loose connective (3)
areolar, adipose, reticular
randomly orientated fibres. (skin). protection. fibroblasts
large, rounded. fat storage (under breasts) fibroblasts.
organized fibres. support. (spleen) binds together soft organs
Dense connective (below epidermis) 3 types
regular, irregular, elastic
fibres run parallel to each other. (tendons/ligaments). lig.-> bone to bone. tend.-> bone to lig.
dermis of skin
rounded columnar. support. (blood vessel tunic)
hyaline, fibrocartilage,elastic, articular. (one kind of cell called chondrocytes and contains collagen fibres)
(nose) costal. speratic fibres. provides flexible support.
pinna of ear
sub type of hyaline. joints, slippery
compact, spongy, (one cell osteocytes)
where are osteocytes found
study of blood
first stage of wound healing
blood has : (2)
rings in bone tissue
E: Lung 1
simple squamous. absoprtion, secretion (one layer/ flattened)
stratified squamous. protection
simple cuboidal. secretion
simple columnar with brush border. absorption, secretion of mucus.
E: Lung 2
simple ciliated columnar. secretion, cilia propel mucus
E: Urinary bladder
transitional. contract and expand
pseudostratified ciliated columnar. secretion, absorption
vascular connective tissue
red & white blood cells. transport oxygen throughout body.
5 types of leukocytes (rbc's)
neutrophil, lymphocyte, monocyte, eosinophil, basophil
phagocytes. engulf / digest bacteria.
phagocytes/macrophage. big cells. macrophages at infection site.
fight parasitic worms / reduce inflammation.
release histamine and prevent clots via heparin
transfer of blood from one person to the other
PVC=3 x [Hb]g/dL
number of cells counted x 200 / 0.02 mm^3
