Homeostasis
Keeping a relatively constant internal physical and chemical conditions despite outside forces
What is Homeostasis?
The transport system of the body responsible for carrying oxygen and nutrients to the body and carrying away carbon dioxide and other wastes; composed of the heart, blood vessels, and blood.
mental disorders often difficult to separate from physical diseases and disorders
what is a Psychiatric disorder?
The basic unit of structure and function in living things
what is a cell?
The study of body structure
What is anatomy?
A feedback loop that causes a system to change in the opposite direction from which it is moving; most of the homeostasis in the body is maintained this way.
What is a negative feedback loop?
The body system that allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat- includes skeletal muscles
what is the muscular system?
A disease that is caused by a pathogen and that can be spread from one individual to another. Usually caused by microorganisms (bacteria, viruses). Examples include strep throat, AIDS, tuberculosis, influenza, food poisoning
What is an infectious disease?
group of tissues that work together to perform closely related functions
what is an organ?
The study of body function
what is physiology?
part of the feedback loop that detects the environmental change (stimulus) in the body and relays information to brain
what is receptor?
the two systems that control most homeostasis in the body
Disorders that affect our ability to protect us from infectious diseases. Examples include AIDS, allergies, rheumatoid arthritis, multiple sclerosis, lupus.
what is an immune disorder?
A group of organs that work together in performing vital body functions.
what is an organ system?
the scientific study of disease
what is pathology?
a normal or target range of values for the environmental parameter (variable)
what is a set point?
The system that includes a network of vessels through which lymph drains from the tissues into the blood. Functions to maintain fluid balance and prevent infections.
What is the lymphatic system?
Disease caused by a deterioration of the body or breakdown of body tissues. Examples include muscular dystrophy, cirrhosis of the liver, Alzheimer's disease, osteoporosis, osteoarthritis
what is a Degenerative disease?
group of similar cells that perform a particular function
what is tissue?
study of the cause of disease
what is etiology?
part of the feedback loop and is usually an organ or gland that responds to a deviation from the set point
what is effector?
Body system that includes the skin, hair, nails, and associated glands. Provides protection and helps to regulate body temperature
what is the integumentary system?
abnormal growths of new tissue that are classified as benign or malignant, i.e. tumors
what is a neoplasm?
The simplest level of the levels of organization. This includes the building blocks that make life possible
what is the chemical level?
Branch of medical science concerned with the incidence, distribution, and control of diseases that affect large numbers of people, i.e. populations
what is epidemiology?
