Diffusion
(a form of passive transport) - the random movement of molecules from regions of greater concentration to regions of lesser concentration - also known as Brownian motion
Function of skeletal system
- (protect) internal organs - allow for (movement) and leverage - (support) the body - provide sites of attachment for muscles, ligaments, tendons - allow for growth - (storage) of energy - (blood cell production)
external sensory features of the pig
- eyes (not open yet) - ears (pinnae) - external nares (nostrils) - vibrissae (whiskers)
filtration
- involves hydrostatic pressure (water pressure), which forces molecules through the cell membrane. - takes place in the kidneys (formation of urine)
turgor pressure
- swelling of a plant cell in a hypotonic solution - prevents it from busting - if lost the plant will wilt
connective tissue
A body tissue that provides support, protection, and binds together other tissues
Solution
A homogeneous mixture of two or more substances
Solvent
A substance capable of dissolving other substances
Solute
A substance that is dissolved in a solution.
Pinocytosis
Cell drinking
Phagocytosis
Cell eating
Proximal
Closer to the origin of the body part or the point of attachment of a limb to the body trunk
active transport
Energy-requiring process that moves material across a cell membrane against a concentration difference
class of fetal pig
Mammalia (artiodactyla)
how many bones in the human body
baby - 270 + adult - 206
facilitated diffusion
carrier proteins along the cell membrane are required to cary specific molecules, such as glucose across the cell membrane into the cell
red blood cells
carry oxygen from lungs to body cells
names of sections in pig dissection
cranial (heed) caudal (butt) ventral (stomach) dorsal (back)
Osmosis
diffusion of water across a selectively permeable membrane
sagittal plane
divides body into left and right
Distal
farther from the origin of a body part or the point of attachment of a limb to the body trunk
white blood cells
fight infection
names of planes in pig dissection
frontal (horizontal) transverse (verticle)
large macromolecules are move in and out of the cell by?
into = endocytosis out of = exocytosis
% change formula
new-old/old x 100
The liquid matrix of blood
plasma
bile production and storage
produced in the liver and stored in the gallbladder
Playsmolysis
shrinking of plant cell
Crenation
shrinking of red blood cells
3 cell layers
simple- single layers stratified- two or more layers pseudostratified- appear to have more than one layer due to cell height, shape, and placement of nucleus
3 cell shapes
squamous- flat or scalelike cells forming a mosaic cuboidal- cells appear to be cube-like in cross section columnar- cells are long and cylindrical like a column
Cytolysis
the bursting of a cell
Tonicity
the concentration of solute in the solvent
Peristalsis
the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward.
passive transport
the movement of substances across a cell membrane without the use of energy by the cell, with the concentration gradient
the matrix is responsible for
the strength associated with connective tissue
epithelial tissue
tissue that covers a body surfaces, lines body cavities, and forms glands
Rostral
toward the nose
Equilibrium
when an equal distribution of molecules exists throughout the system
axial skeleton
Portion of the skeletal system that consists of the skull, rib cage, and vertebral column
hypertonic solution
Solute concentration is greater than that inside the cell - cell loses water
hypotonic solution
Solute concentration is less than that inside the cell - cell gains water
appendicular skeleton
The portion of the skeleton that is made up of pelvic girdle, hand, arms, feet, and legs
selectively permeable
a property of cell membranes that allows some substances to pass through, while others cannot
isotonic solution
a solution whose solute concentration is equal to the solute concentration inside a cell
