What is the defenition of Biology?
|
Study of Life
|
|
What is the defenition of Life?
|
State of existance that distinquishes living from non-living things.
|
|
Definition of Anatomy?
|
study of structure
|
|
Definition of Physiology?
|
Study of functions of body
|
|
Characteristics of Life
|
Grow, reproduce, abitlity to metabolise, respire, motility, comprised of cells, contain carbon, irritability, have a lifespan, adapt, evolve, are organized
|
|
Stages of metabolism
|
Catabolism-complex substances to simple protein to amino acid
Anabolism-converts simple to complex amino acid to protein |
|
Defenition of irritability
|
respond to stimuli
|
|
Organization of life
|
biosphere-> biomes-> communities -> populations -> Individuals -> organ systems
-> organs -> tissue -> cells |
|
Integumentary system organs
|
skin, hair, nails, exocrine glands (sweat, oil, milk, tear, secreting glands)
|
|
Integumentary system functions
|
protection, temp regulation, irritability, excretion, barrier, involved in immunity, synthesis of vitamin D
|
|
Skeletal system Organs
|
bones
|
|
skeletal system function
|
protection, support, movement (acts as the rigid bar of lever), stores fat and minerals, hematopoiesis
|
|
Muscular System organs
|
muscles: skeletal, smooth, cardiac
|
|
muscular system function
|
movement (applies effort to rigid bar of lever), heat production of thermogenesis
|
|
Nervous system organs
|
brain, spinal cord, nerves
|
|
Nervous system function
|
provides homeostasis via electrical messages, able to sense, itegrates-interprets-and decides on response, responds
|
|
Endocrine system organs
|
pituitary, pineal, thyroid, parathyroid, thymus, adrenal
|
|
endocrine system function
|
provides homeostasis via chemical messages/hormones: growth, reproduction, H2O balance, electrolyte balance, energy balance, emergency maintenance, immunity
|
|
reproductive system organs
-male |
testes, epididymus, vas deferns, semenal vesicles, prostate, cowpers gland, penis
|
|
reproductive system organs
-female |
ovaries, fallopian tubes, uterus, vagina, external genitilia (vulva)
|
|
What is the function of the reproductive system?
|
Continuation of species
|
|
The Organs of the urinary system.
|
Kidneys, ureters, bladder, urethra
|
|
Function of the Urinary System
|
Excretion, filters blood, regulates: blood concentration, blood volume, blood pH, and blood pressure
|
|
Organs of the Cardiovascular system
|
Cardio: Heart
Vascular (Vessels): arteries, arterioles, metarterioles/capillaries, venules, veins |
|
Function of the Cardiovascular system
|
pumps (heart) blood thru conduits (vessels) deliever nutrients & wastes to and from tissues
|
|
Organs of the lymphatic system
|
Lymph nodes, lymph vessels, tonsils, spleen, liver, thymus gland
|
|
Function of the lymphatic system
|
1st line of defense, removes excessive fluid from tissue, picks up leaked protein from blood tissue, picks up fats from GI tract and transports it to liver
|
|
Respiratory system organs
|
nose, pharynx, larynx, trachea, bronchi and bronchial tree, lungs
|
|
Digestive system organs
GI |
oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, rectum, anus
|
|
Digestive system organs
Accesory |
teeth, tongue, salivary glands, pancreas, gallbladder, liver
|
|
fuction of digestive system
|
Ingestion, movement of food, digestion, absorption of nutrients, defecation
|
|
Definiton of Homeostasis
|
Balance
|
|
Function of Homeostasis
|
provides for optimum performance of the organs and organ systems
|
|
What has to be balanced?
|
blood chemistry, water, electrolyte, blood pressure, temperature, hormones, pH
|
|
What is the mode of homeostasis?
|
Feedback systems
|
|
What is the defenition of a feedback system?
|
watchdog system
|
|
What is the function of the feedback system?
|
provides a route by which the brain is alerted of body status and allows it to respond to that status
|
|
Components of a feedback system
|
Receptor, Control Center(Brain) and Effector
|
|
What is a receptor?
|
picks up stimulus(input) and sends info to brain via afferent(sensory) nerves
|
|
What does the control center do?
|
Interperts, integrates and decides on response(output) via efferent(motor) nevers info leaves brain and travels to effector
|
|
What is the purpose of the effector?
|
doer of action. performs activity assigned by brain
|
|
Types of feedback systems
|
Negative and Positive
|
|
What is a negative system
|
More common, always brings about homeostasis, Stimulatory-Inhibitory effect, output(response) counteracts or negates input(stimulus)
|
|
What is a postive system
|
Least common, can be destructive, Stimulatory-Stimulatory, output intensifies input
|
|
What is an example of each
|
Negative: lowers bp to normalcy; highers glucose to normalcy
Postive: Labor; clotting; disease |
|
What is a stressor?
|
any circumstance that upsets normal body function
|
|
What are the types of stress?
|
Eustress: good stress: exercise
Distress: bad stress: temp change, pressure change, disease |
|
What is the definition of disease?
|
andy disturbance in normal body structure or function and homeostatic imbalance brought on by disturbance
|
|
What are the classifications of disease?
|
Congenital(inherited), degenerative, inflammatory, metabolic(hormone imbalance), neoplasmic(cancer,growth)
|
|
What are the types of disease?
|
Local: area of body is affected
Systemic: several to many areas of body are affected |
|
What is the definiton of diagnosis?
|
thorough or complete knowledge
|
|
