Anatomy

The study of form/structure

1

Palpation

Feeling with hands (ex: pulse)

2

Auscultation

Listening to natural sounds of the body (heart, lungs)

3

Percussion

Tapping for echo sounds- reveals abnormal pockets of air/fluid

4

Physiology

The study of function

5

Properties of life

Cellular organization, biochemical unity (proteins, lipids, carbs, DNA), metabolism, responsiveness, development

BORDM

6

Catabolism

Breaking bond; breaking things down to release energy

7

Anabolism

Making bond; synthesis that requires energy to go into chemical bonds

8

Excrete

Only used for urine/feces

9

Secretion

Tears, sweat, etc.

10

Pathology

Study of disease (Patho- means sick/ill)

11


Reductionism

Suggests that a human body can be understood by studying its simpler components

12

Holism

Suggest that there are properties possessed by the whole organism that are not apparent from the study of its parts, such as psychological factors

13

The inductive method of the scientific method

Involves making numerous observations and then forming generalizations and predictions

14

The hypothetico-deductive method

Begins with the formulating of a hypothesis followed by a deduction.

15

Scientific fact

Observation

16

Law of nature

Generalization supported by much scientific evidence

17

Theory

Well-substantiated statement designed to explain a natural phenomenon (simple event)

18

Dynamic (changing) equilibrium

Balanced change

19

Feedback loops

General name for these mechanisms which alter the original changes that triggered them

20

Extrinsic regulation

Involves nervous or endocrine (hormone) systems

21

Hormones

Chemical messengers produced in one part of the body having an effect in another (target)

22

Negative feedback

Main way body returns to stable conditions (homeostasis); ex: thermostat; vasoconstriction/vasodilatation of blood vessels to exchange heat with outside environment

23

Integumentary organ system

Protect tissues, regulate body temp, support sensory receptors (ex: skin, hair, nails, sweat glands)

24

Skeletal system

Provide framework, protect soft tissue, provide attachments for muscles, produce red blood cells (bones, ligaments, cartilage)

25

Muscular system

Cause movements, maintain posture, produce body heat (muscles)

26

Nervous system

Detect changes, receive and interrupt sensory info, stimulate muscles and glands (brain, spinal cord, nerves, sense organs)

27

Endocrine system

Control metabolic activities (glands that secrete hormones (pituitary, thyroid, adrenal, etc.)

28

Cardiovascular

Move blood through blood vessels and transport substances through body (heart, arteries, capillaries, veins)

29

Lymphatic

Return tissue fluid to the blood, carry certain absorbed food molecules, defend the body against infection (lymphatic vessels, lymph nodes, thymus, spleen)
