Anatomy & Physiology Flashcards
<p>Define Anatomy</p>
<p>The science of STRUCTURES and the relationships among structures of the human body.</p>
<p>Define physiology</p>
<p>The science of body FUNCTIONS that is how the body parts work</p>
what are the levels of organization
- Chemical
- Cellular
- Tissue
- Organ
- System
- Organismal
<p>how many levels of organization are there</p>
<p>6</p>
<p>The Chemical level is comprised of what</p>
<p>atoms and molecules</p>
<p>2 or more atoms joined together are called what</p>
<p>molecules</p>
when is the cellular level is reached
when CELLS combine to form structures
<p>The tissue level is reached when</p>
<p>groups of cells and materials work together to preform a function</p>
<p>What are the four basic types of tissues in the body</p>
<p>- Epithelial
<br></br>- Connective
<br></br>- Muscular
<br></br>- Nervous</p>
The organ level is reached
when different kinds of tissues join together to form body structure
<p>What is a common characteristic of organs</p>
- Recognizable shape
- composed of two or more DIFFERENT tissues with a common function.
<p>What are the tissues that make up the stomach</p>
Serous Membrane
Smooth Muscle Tissue Layers
Epithelial Tissue
Describe the stomach serous membrane
the outside of the stomach that protects and reduces friction
Describe the smooth muscle tissue layers of the stomach
contracts to churn and mix food and push to small intestine
<p>Describe the epithelial tissue layer of the stomach</p>
<p>innermost lining of the stomach contributes fluid and chemicals that aid digestion</p>
<p>The system level is described as</p>
<p>Related organs that have a common function</p>
The body systems work together for what purpose
Maintain health
protect against disease
allow for reproduction
<p>Describe the Organismal level</p>
<p>The largest level of organization</p>
<p>Which body system helps eliminate waste</p>
<p>The Urinary system</p>
<p>Define Homeostasis</p>
<p>the maintenance of relatively stable conditions</p>
<p>What systems control homeostasis</p>
<p>Nervous and Endocrine System</p>
<p>When the NERVOUS system detects changes how does it send messages</p>
<p>Nerve impulses</p>
<p>How does the ENDOCRINE system enact change</p>
<p>Secreting molecules called HORMONES</p>
<p>Homeostasis is maintained my means of</p>
<p>Feedback systems</p>
<p>what is a feedback system or feedback loop</p>
<p>Cycle of events in which a condition in the body is continually MONITORED, EVALUATED, CHANGED, and so on</p>
<p>Controlled conditions are body conditions that are</p>
<p>Monitored to maintain homeostasis</p>
<p>A disruption that causes change in a controlled condition is called</p>
<p>Stimulus</p>
<p>What are the 3 basic components that make up a feedback system</p>
- Receptors
- Control Center
- Effector
<p>what is a Receptor in the feedback system</p>
<p>A body structure that monitors change in a controlled condition and sends information to the control center</p>
What does the control center in the feedback system do
sets the range of value within which a controlled condition should be maintained.
What is a effector in the feedback system
a body structure that receives output from the control center and produces a response
<p>Describe the feedback system loop</p>
STIMULUS --> CONTROLLED CONDITIONS --> RECEPTORS --> CONTROL CENTER --> EFFECTORS --> RESPONSE-
