Section 1

Question Answer
Integumentary `protects deeper organs from mechanical, chemical, and bacterial injury and from drying out
Skeletal body support and protection go internal organs
Muscular contract or shorten, allows locomotion
Nervous allows body to detect changes in it'd internal and external environment and response to stimuli
endocrine maintain homeostasis, promotes growth and development produces hormones
cardiovascular transport system that carries blood containing oxygen, carbon dioxide, nutrients, wastes, ions, hormones
Lymphatic / Immunity protect body from foreign substances
Respiratory keeps the blood continuously supplied with oxygen while removing carbon dioxide
digestive breaks down ingested food to smaller particles
Urinary rids the body of nitrogen containing wastes
Reproductive provide sperm and eggs
Tissuecells similar in structure and function
organ composed of two or more tissue types
organ system group of organs that act together to perform particular body functions
Cellthe structural and functional unit of all living things
cells can maintain boundaries, metabolize, reproduce and grown, digest nutrients, dispose of wastes , respond to stimulus
Nucleus contains genetic material, DNA ( CONTROL CENTER OF CELL )
Plasma Membraneseparates cell contents from the surrounding environment
Cytoplasm cell content between the nucleus and plasma membrane
Ribosomesspherical body composed of RNA and protein
Endoplasmic Reticulum ( rough )storage and transport of proteins made on the ribosomes
ER ( smooth ) site of steroids and lipid synthesis, lipid metabolism, and drug detoxification
Golgi apparatus packaging proteins for export from the cell into the plasma membrane
Lysosomesdigest worn out cell organelles and foreign substances
Peroxisomes detoxify alcohol, free radicals, and other harmful chemicals
Mitochondria contain onyxes that oxidize food stuff to produce cellular energy ATP ( powerhouse )
Centrioles direct the formation of the mitotic spindle during cell division, form the base of cilia and figillia
Cytoskeletal elements cellular support, cell mobility, help determine cell shape
Anatomy study of the structure of body parts and their relationships with one another
Physiology study of the functions of body parts how they work together
Homeostasis maintenance of relatively stable internal conditions despite continuous changes in environment
Homeostatic variables receptors control center and blood volumes
Negative Feedback returning certain variables to homeostasis
Receptors ( sensors ) receives stimuli ( detects change )
Stimulus Causes a change
Positive feedback exaggerate the stimulus
Feedforward used in anticipation of change
Organic Carbohydrates , Lipids, Proteins, Nucleic Acids
Inorganic ( lacking carbon ) water electrolytes
most accessible organic carbohydrates
3 categories of sugar monosaccharides, disaccharides, polysaccharides
condensation dehydration synthesis ) removal of water, to make
hydrolysis water, to break
carbohydrates includes sugars and startch also carbon hydrogen and oxygen
Monosaccarides glucose , 1 single sugar , contains 3-7 carbons, ribose found in DNA,
Monomers smallest unit of carbohydrates
disaccharides 2 sugars , to large to pass through cell membrane, ( sucrose, maltose, lactose ) formed by dehydration synthesis
polysaccharides many sugars , formed by dehydration synthesis of monomers
starch formed by plants
glycogen used by animals

Question Answer
Lipids contains c,h,o but less than in carbohydrates and sometimes contain C
LIPIDS are insoluble in water
Types of lipids Trigylcendes or neutral fats, phospholipids, steroids, elcosanoids
