Flashcards in Chapter 1 Introduction to A&P Deck (82)
The study of the form or structure of the body.
The study of the function of the body.
What does form determine?
Form determines function
Type of anatomy that needs a microscope to see these structures?
Study of individual cell.
Study of tissues.
Simplest form of life.
Type of anatomy that you can see structures with your eye.
Another term for macroscopic anatomy
Groups of organs that form a system (heart, vessels)
What are the levels of organization by order?
*Remember organization at each level determines the characteristics and functions of higher levels!*
What are the 4 types of tissues?
Where does life begin?
Existence of a stable environment; a set desired range for body functions.
What happens in the body when a organ can not maintain homeostasis?
The organ will not survive
A sensor that detects a change or stimulus.
Receives and process the stimuli.
*Think dial or thermostat*
Cell or organ that responds to a stimuli.
What are the two types of Regulartory Mechanisms?
Regulatory Mechanism when a variation outside the desired Homeostatic range triggers a response to correct the situation. Results are always the opposite of what ever condition initiated the response. The provides stability or sets a limit to a process.
Example: When your blood pressure gets too high the heart will beat slower. This brings your blood pressure back to normal.
Example: When the temperature sends a signal to the thermostat which turns on the air conditioner.
Regulatory Mechanism when a stimuli produces a response that increases the beginning effect. Resules are always the same as whatever condition initiated the response this accelerates a process to completion.
Example: An increased temperature sends a signal to the thermostat which turns on the heater.
What are 5 major needs of organisms?
-Gases (Oxygen and Carbon dioxide)
-Salts, acids, bases
System of the body that controls temperature, and prevents bacterial infections.
Organ of the Integumentary system?
System of the body that supports and makes blood?
Organ of the skeletal system?
System of the body that supports, allows movement, and produces heat?
Organ of the muscular system?
System of the body that directs stimuli and activities?
