Chapter 4 Overview; Anatomy & Physiology Flashcards
Physiology
Is the science and study of the vital processes, mechanisms, and functions of an organ or system
Kinesiology
Is the scientific study of muscular activity and the anatomy, physiology, and mechanics of body movement
Pathology
Is the study of the structural and functional changes caused by disease
Homeostasis
Is the internal balance of the body
Disease
Is an abnormal and unhealthy state of all or part of the body wherein it is incapable of carrying on its normal function
Symptom
Is subjective evidence of disease or bodily disorder
Sign (of disease)
Is an observable indication of disease or bodily disorder
Stress
Is any psychological or physical situation or condition that causes tension or strain
Adrenal glands
Situated on the top of each kidney
Produce; epinephrine, norepinephrine, and corticosteroids
Fight or flight hormones
Works in conjunction with the pituitary and the hypothalamus
Atherosclerosis
Is characterized by an accumulation of fatty deposits on the inner walls of the arteries
Pain
Is the result of stimulation of specialized nerve endings called nociceptors.
It has a primarily protective function in that it warns of tissue damage or destruction somewhere in the body
Ischemia
Is localized tissue anemia caused by obstruction of the inflow of blood
Pain-spasm-pain cycle
Pain causes muscle contraction and ischemia, thereby causing a spasm that causes more pain
Bacteria
Are minute, unicellular organisms exhibiting both plant and animal characteristics and are classified as either harmless or harmful
Virus
Is any class of submicroscopic pathogenic agents that transmit disease
Fungus
Is a diverse group of organisms potentially capable of causing disease that thrive or grow in wet or damp areas and live by absorbing nutrients from organic matter
Parasite
Is an organism that can potentially cause disease that exists and functions at the expense of a host organism without contributing to the survival of the host
Local infection
Is invading organism confined to a small area of the body
Systemic infection
Is invading organisms that have spread throughout the body
Inflammation
Is a protective tissue response characterized by swelling, redness, heat, and pain
Fever
Is an elevated body temperature
In sudden onset or fever greater than 102° get immediate attention
Fevers 106°-108° can cause damage or even death
Leukocytes
White blood cells
Phagocytes
Engulf and digest the invading organisms and the damaged tissue debris (phagocytosis)
Fibroblasts
Connective tissue cells
Migrate to the area and produce connective tissue fibers that begin to span the wound, providing a structure for regenerating vascular and epithelial tissue
Scar
A dense fibrous tissue that forms as an injury, wound, burn, or sore heals
Wellness
Is a concept where people take personal responsibility for their own physical, emotional, mental, and spiritual state of health
