epidermis

1st multilayered layer

molecule

2 or more atoms chemically bonded; same atoms or different atoms

homeostasis

ability to maintain stable internal balance given a change in outside conditions

superior

above another structure or area or closer to the head. (The heart is superior to the diaphragm.)

why are enzymes important

acts as a catalysis to bring about a reaction

gap junction

allows neighboring cells to communicate

ions

an atom or molecule with a net electric charge due to the loss or gain of one or more electrons

loose conn tissue

areolar/rectangular not dense, intersecting fibers with different strength, take up space holds organs together

skeletal system

attachment to muscles, protects organ

atom

basic unit of chemical element; protons, neutrons, electrons

bifurcated

branching; unique to heart

negative feedback

bringing condition back to set point

plasma membrane phospholipid bilayer

cholesterol, transmembrane protein, glycoprotein, glycolipids

cytokinesis

cleaving of cell

rectangular epith tissue

columar

cytoplasm

consists of cells between nucleus and cell membrane

nucleus

contains DNA, surrounded by nuclear envelope covered in pores that allows things to travel through

square epith tissue

cubiod

peroxidases

detoxifying chemicals/convert to less harmful substances

forms of passive transport

diffusion, filtration, osmosis

lysosome

digest/ destroy substances inside cell

leak channels

every time pump lets something in something leaks out

respiratory system

exchanges respiratory gases with the environment

cytoskeleton

fibrous proteins that provide shape, structure, protection, and attachment

anatomy

form

physiology

function

desmosomes

fusions of membrane between one cell and the next; strongest connection

cytosol

gel-like and holds organelles

dermis

hair folicals, sensory organs/receptors, sebaceous glands, blood vessels, muscles

cardiac muscle

heart movement

What is ATP

high energy molecule

hypertonic

higher concentration of solution

endocytosis

into cell

smooth muscle

involves movement of internal organs

phagocytosis

larger things into cell

epithelial tissue

line cavities and surfaces

glycolipids

lipids within membrane that is conjugated to sugar

dense regular conn tissue

little vasculature, tight parallel fibers; linear strength required (tendons/ligaments)

hypotonic

lower concentration of solution

urinary system

maintains constant internal environment through the excretion of nitrogenous waste

rough ER

major site of protein

sodium potassium ATPase

major solute pump of all cells; 1) creates concentration gradient 2) establish electrical gradient

where is ATP made

mitochondria

bulk transport

move lots of things at once; endocytosis and exocytosis

diffusion

movement of solutes away from an area of higher concentration

active transport

movement of substance requiring energy

passive transport

movement of substance without using energy

pinocytosis

movement of water into cell

muscular system

moves body, generation of heat, internal support of fluids

control mechanisms associated with homeostasis

negative feedback, positive feedback, feed-forward

are all body systems required

no- reproductive system

isotonic

normal body solution concentration (300

selective permieability

only allow select molecules to cross in and out of cell

exocytosis

out of cell

Golgi Apparatus

packaging and shipping facility; enclose products within membrane "box" either to interior of cell, cell membrane, or expelled

mitosis

part of cycle of cell where DNA is separated

digestive system

physical and chemical breakdown of food

mitochondria

powerhouse of cell; majority of ATP production

osmosis

process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one

centrioles

process of cellular division; function in organization of microtubules

reproductive system

produces and secretes hormones, produces and releases egg and sperms cells

integumentary system

protects underlying tissues; regulates body temp

parts of feedback system

receptor, control center, set point, effector

nervous system

regulated and integrates functions of neurons

endocrine system

regulates and integrates body functions via hormones

lymphatic system

returns tissue fluids to bloodstream

single layer of epith tissue

simple

smooth ER

site of non-protein production

organelle

specialized structure within a cell

flat epith tissue

squamous

multiple layer of epith tissue

stratified

levels of organization concerning anatomy

subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms

hypodermis

subcutaneous tissue (where large blood vessels are)

simple diffusion

substance passes through a membrane without the aid of an intermediary such as a integral membrane protein

enzymes

substance produced by a living organism

Endoplasmic reticulum

synthesis of cellular production

permeability

the state or quality of a material or membrane that causes it to allow liquids or gases to pass through it.

dense irregular conn tissue

tight intersecting fiber

tight junction

tightly holds two membranes together like ziplock bag not letting anything through

connective tissue

tissue that connects, supports, binds, or separates other tissues or organs

cranial

towards head

deep

towards inside

superficial

towards outside

caudal

towards tail

cardiovascular system

transport nutrients, respiratory gases, waste, and heat; transports immune cells and antibodies

facilitated diffusion

transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.

positive feedback

trying to drive condition to get rid of stimuli

skeletal muscle

voluntary movement of skeleton
