AMP 1 Ch 1
the heart and blood vessels work together to transport blood, containing oxygen, nutrients, and other substances, throughout the body
Cardiovascular system
is the study of biological molecules
Molecular biology
2nd part of the chemical level
Molecules combine in specific ways to form organelles, which are the basic unit of living cells
is the process of producing more cells or organisms
Reproduction
produces sex hormones and gametes for the production of offspring, female provides support for the developing fetus
Reproductive systems
provides airflow to allow exchange of oxygen and carbon dioxide between the body and the atmosphere
Respiratory system
is the ability to detect changes in the internal or external environment and respond to them
Responsiveness, or irritability
Produces antibodies that attach to foreign substances
immune
Removes and filters excess fluid from tissues
lymphatic
Most homeostatic control mechanisms are_______________ ______________ mechanisms that reduce or stop the effect of the stimulus, preventing severe changes within the body
negative feedback
Which organ systems function as control systems, communicating with other cells/organs to regulate their activities?
nervous and endocrine systems
Which level of structural organization is considered to be the highest level?
organismal
The regulated factor or event is called the
variable
the most abundant chemical substance in the body, provides an environment for chemical reactions and a fluid medium for secretions and excretions
water
eliminates nitrogenous wastes, and regulates water and ion balance
Urinary system
is the process of breaking down food into molecules that are usable by the body
Digestion
breaks down food into molecules that can be absorbed into the body, stores and eliminates wastes
Digestive system
source of hormones that regulate the processes of the body
Endocrine system
is the study of structures large enough to be seen with the naked eye
Gross (macroscopic) anatomy
is an increase in size in body parts or the whole organism
Growth
is the study of tissues (type of microscopic anatomy)
Histology
is the ability of the body to maintain a relatively constant internal environment, regardless of environmental changes
Homeostasis
communication systems involving various components
Homeostasis is controlled through
focuses on development that occurs before birth (type of developmental anatomy)
embryology
Controls the body with chemical molecules called hormones
endocrine
Excess nitrogenous waste and excess ions are removed from the blood and eliminated from the body by the
excretory system
1st part of the chemical level
Atoms, tiny building blocks of matter, combine to form molecules
is a structure that carries out the response directed by the control center
An effector
is the study of the structure of body parts and their relationships to each other, and physiology is the study of the function of body parts
Anatomy
must be within an appropriate range so that proper gas exchange occurs in the lungs
Atmospheric pressure
is the study of individual cells (type of microscopic anatomy)
Cytology
is the study of the change in body structures over the course of a lifetime
Developmental anatomy
is the process of removing wastes
Excretion
What does the principle of complementarity of structure and function mean?
Function reflects structure and structure determines function
hair, skin, nails that protect the deeper tissues of the body
Integumentary system
circulates excess fluid to blood, removes debris, houses cells of the immune system, which protect the body from disease and damage
Lymphatic and immune systems
allows an organism to maintain separate internal and external environments or separate internal chemical environments
Maintaining boundaries
includes all chemical reactions that occur in the body
Metabolism
is the study of structures that are too small to be seen with the naked eye
Microscopic anatomy
allows the organism to travel through the environment, and allows transport of molecules within the organism
Movement
allows movement, maintains posture, and produces heat
Muscular system
control system that responds to internal and external changes, activating the appropriate response
Nervous systemNervous system
is required for the chemical reactions of the body to occur at the proper rate
Normal body temperature
are consumed chemical substances that are used for energy and cell building
Nutrients
is required by the chemical reactions that release energy from foods
Oxygen
is the study of structural changes associated with disease
Pathological anatomy
enhance the effect of the stimulus, resulting in an amplifying effect of the stimulus, creating cascades that are used to control events that do not require continuous adjustment
Positive feedback mechanisms
is the study of internal structures using specialized visualization techniques
Radiographic anatomy
monitor changes in the environment and send some kind of signal to a control center
Receptors
is the study of all body structures in a given body region (type of gross anatomy)
Regional anatomy
bones protect and support organs, attach muscles, and provide for blood cell formation
Skeletal system
is the study of internal body structures as they relate to the overlying skin (type of gross anatomy)
Surface anatomy
is the study of all structures in a body system (type of gross anatomy)
Systemic anatomy
is the smallest unit of life, and varies widely in size and shape according to the cells' function
The cellular level
is the simplest level of organization
The chemical level
is a structure that determines the set point for a variable, analyzes input, and coordinates an appropriate response by signaling an effector
The control center
is made up of discrete structures that are composed of at least two groups of tissues that work together to perform a specific function in the body
The organ level
is a group of organs that work closely together to accomplish a specific purpose
The organ system level
is the total of all structures working together to promote life
The organismal level
is based on the fact that what a structure can do is related to its form
The principle of complementarity of structure and function
feeds back to either reduce or amplify the effect of the stimulus
The response from the effector
is groups of cells having a common function
The tissue level
Delivers oxygen and nutrients to the tissues
cardiovascular
Homeostatic imbalances often result in ______________
disease
