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
