BIO 201 Exam 1 Review Questions and
Correct Answers
Epithelial tissue ✅protection, absorption, filtration, excretion, secretion, sensory
reception
Eg. Stomach lining and skin
*innervated and avascular
Muscle tissue ✅excitable, contractile tissue for movement
Nervous tissue ✅excitable tissue used to send short term signals throughout the body
-function is to control and communicate
Eg. Positive and negative feedback
Connective tissue ✅-living cells in a non-living matrix
-function is to support
Eg. Under every epithelium
Structural elements of connective tissue ✅1. Ground substance
2. Fibers
3. Cells
4 types of connective tissue ✅1. Connective tissue proper
2. Cartilage
3. Bone
4. Blood
3 types of cartilage ✅1. Hyaline
2. Elastic
3. Fibrocartilage
Necessary life functions ✅1. Maintaining boundaries
2. Movement
3. Responsiveness
4. Digestion
5. Metabolism
6. Disposal of wastes/excretion
7. Reproduction
, 8. Growth
Maintaining boundaries ✅separation between internal and external environments
Movement ✅-contractility
-happens at both gross and cellular/chemical levels
-of body parts (skeletal muscle)
-of substances (cardiac and smooth muscle)
Responsiveness ✅-ability to sense and respond to stimuli
-stimulus=change in the environment
-e.g. Your body gets hot, you need to cool down, withdrawal reflex
-irritability=an organism responding to a change in their environment
-adaptability=the potential an organism has to make this change
Digestion ✅-absorption of simple molecules into the blood
-take up nutrients to produce energy and keep life systems going
Metabolism ✅-all chemical reactions that occur in body cells
-encompasses both anabolism and catabolism
Disposal of wastes ✅-removal of wastes from metabolism and digestion
-e.g. Urea, co2, feces
Reproduction ✅-producing offspring to carry on life
-cellular division for growth or repair
Growth ✅increase in size of a body part or of organism
-e.g. Egg+sperm=zygote which divides to form human organism
Microscopic anatomy ✅e.g. Cytology and histology
-need a microscope/cannot see with naked eye
The cell ✅smallest living units of anything
--ecf, cytoplasm, cell membrane, cytoskeleton
Levels of organization (backwards) ✅organism, organ system, organ, tissue, cell,
(molecule/atom/organelle)
Survival needs ✅1. Nutrients
2. Oxygen (to make atp!)
3. Water (environment of chem reactions)
4. Normal body temperature (37 c)
