Additional Biology Flashcards

 


 

Cards

Term
Define Anatomy
Definition
The science of the structure of body and its relationship.
Term
Define Physiology
Definition
The study of physical and chemical processes involved in the functioning of the human body
Term
Define Metabolism and its two categories
Definition

The sum of all the physical and chemical processes by which living organisms are produced and maintained, and also the transformation by which energy is provided for vital processes and activities.

 

Anabolism

 

Catabolism

Term
Catabolism
Definition
A methatbolic process through which living organisms break down complex substances to simple compunds, liberating energy for use in work, energy storage, or hear production.
Term
Anabolism
Definition
A constructive metabolic process characterized by the conversion of simple substances into larger, complex molecules.
Term
List the levels of structural organization in increasing order
Definition
Chemical-Cellular -> Tissue -> Organ -> Organ System -> Organismal Level
Term
Homeostasis
Definition
The maintenance of a stable equilibrium in biological system that oppresses external or internal disturbabnce.
Term
Define the two feedback mechanisms
Definition
Negative feedback, Positive feedback
Term
Negative Feedback
Definition
Consists of reducing the output or activity of any organ or system back to its normal range of functioning. A good example of this is regulating blood pressure
Term
Positive Feedback
Definition
When a system tends to increase output. The product of a reaction influences or increases the forward direction of the system.
Term
List the 4 major components of a negative feedback mechanism
Definition
Stimulus, Sensor, Integrator, and Effector
Term
Principle of Complementarity of structure and function
Definition
Each component of human body is structured to perform a specific function
Term
What are examples of ectoparasites
Definition
A parasite that can be live on the outside of humans or animals.  Fleas, ticks, lice, etc.
Term
Vectors of infectious disease
Definition
Vectors are the transmitters of disease causing organisms that carry the pathogens. A vector is an animal, insect, or living organism that can carry and transmit communicable diseases to humans.
Term
Define Incidence
Definition
The rate at which a certain event occurs within a specific time period (the number of a new cases of a disease during a period of time in a population at risk).
Term
Define Normal Micro flora
Definition
Multitudes of harmless bacterias inhabit in human body.
Term
Define Opportunistic Pathogens
Definition
An infectious microorganism that is normally a commensal or does not harm its host but can cause disease when the host’s resistance is low.
Term
Define Prokaryotes
Definition
Any of the group of organisms primarily characterized by the lack of true nucleus and other membrane-bound cell compartments... unicellular bacteria.
Term
Gram Staining is used...
Definition
To define subcategories of bacteria.
Term
Fungi that reproduce by budding
Definition
Yeast
Term
Common symptoms of infectious disease
Definition
Fever, Muscular Pain, Lethargy, Headache
Term
Define Prodromal Stage
Definition
The primary stage of certain infectious diseases during which early/initial symptoms appear.
Term
Define Nosocomial Infections
Definition
Infections that were not present before the patient came to a hospital, but were acquired by a patient while in the hospital.
Term
Examples of Diseases caused by exotoxins
Definition
Diphtheria
Term
What is the function of Penicillin?
Definition
Inhibits cellular synthesis between the cellular walls of a bacterium.
Term
Broad Spectrum Antibiotics
Definition

An antibiotic with effects against a wide range of disease-causing bacterium.

 

Term
Describe make up of the Immune System.
Definition
Red bone marrow, spleen, thymus gland, lymphoid gland, T and C lymphocytes
Term
Define Major Histocompatibility Complex Molecules
Definition
A large gene-dense region found in most vertebrates that plays an important role in the immune system and autoimmunity
Term
Class I Major Histocompatibility Complex (MHC) location
Definition
Are found on every nucleated cell in the body (not red blood cells).  Displays protein fragments to T cells, marking healthy cells vs cells with foreign matter.
Term
Define Macrophages
Definition
"Big Eaters" - Engulfs and Digests Foreign Particles
Term
Define Cytokines
Definition
Intercellular protein messenger molecules that regulate movement, proliferation, and differentiation of immune and other cells.

Definition
This is a process that occurs in the Thymus
Term
Specific immune mechanisms include...

B lymphocite
Term
Define Clusters of Differentiation (CD)
Definition
Surface proteins that act as markers of recognition for various T and B cells
Term
Function of Lymph Nodes
Definition
1) Assist in removing foreign materials from lymph channels
2) Cents for immune cell proliferation
Term
Examples of Active Immunity
Definition
Immunity reused by a response to the exposure to a pathogen agent
Term
Examples of non-specific diseases
