Passive processes

1. account for the movement of fats and respiratory gases through the plasma membrane
2. include osmosis, simply diffusion, and filtration
3. use hydrostatic pressure or molecular energy as the driving force

2

active processes

1. explain solute pumping, phagocytosis, and pinocytosis
2. may occur against concetration and/or electrical gradients
3. move ions, amino acids, and some sugars across the plasma membrane

3

epithelium

1.lines body cavities and covers the body's external surface
2. cells may absorb, secrete, and filter
3. synthesizes hormones

4

muscle

1. pumps blood, flushes urine out of the body, allows one to swing a bat
2. transmit electrochemical impulses
3.major functino is to contract

5

nervous

1. transmit electrochemical impulses
2. most involved in regulating and controlling body functions.
3. forms nerves and the brain

6

connective

1. anchors, packages, and supports body organs.
2. the most durable tissue type
3. abundant nonliving extracellular matrix
4. most widespread tissue in the body
5.

7

dense

attaches bones to bones and muscles to bones
-the dermis of the skin

8

adipose

1. acts as a storage depot for fat
2. insulates against heat loss

9

fibrocartilage

makes up the intervertebral discs

10

osseous

-forms the hip bone
-matrix hard owing to calcium salts;provides levers for muscles to act on

11

areolar

composes basement membranes; a soft packaging tissue witha jelly like matrix

12

hyaline cartilage

-forms the larynx, the coastal cartilages of the ribs, and the embryonic skeleton
-firm, structurally amorphous matrix heavily invaded with fibers;appears glassy and smooth

13

elastic cartilage

provides a flexible framework for the external ear

14

molecular motion

-reflects the kinetic energy of molecules
-is random and erratic

15

velocity of molecular movement

-is lower in larger molecules
-increases with increasing temperature
