Body Orientation Review Flashcards
What are the levels of structure?
Chemical, Cellular, Tissue, Organ, Organ system, Organism
Of the necessary life functions, which suggests the ability to sense change in the environment and then react to them?
Responsiveness
What are involved in maintaining homeostasis?
Effector, Control Center, Receptor
What are essential to survive?
Appropriate body temperature, Atmospheric pressure, Nutrients, Oxygen, and Water
What are considered excretory systems?
Urinary and Digestive system
Which systems are responsible for communication within the internal environment?
Endocrine and Nervous system
True or False: Anatomy and Physiology are interdependent and cannot function in the absence of the other
True
True or False: As it relates to maintaining homeostasis, the effector sends a message to the control center that there needs to be a change
False
True or False: Gross anatomy involves examining very small structures
False
True or False: Most of the mechanisms in the body that control homeostasis in the body are positive feedback mechanisms
False
True or False: Childbirth is an example of a negative feedback system
False
True or False: The ability of both the nervous and endocrine system to communicate with the rest of the body is referred to as a neuroendocrinological response
True
True or False: The endocrine system’s control of bodily function is the only system that can control bodily function
False
What is the purpose of the integumentary system?
Protects the internal tissues from the external environment
What is the purpose of the skeletal system?
Provides the framework and produces red blood cells
Of the three mechanisms maintaining homeostasis, which is triggered by a change in the environment requiring the body to adapt?
Receptor
True or False: Receptors only respond to a change in the external environment
False
Which are the necessary life functions?
Digestion, Excretion, Growth, Maintenance of Boundaries, Metabolism, Movement, Responsiveness, and Reproduction
Which organ system removes nitrogen-containing wastes from the blood and flushes them from the body?
Urinary
Which mechanisms analyzes information from the environment and determines the appropriate response?
Control Center
The branch of biological science that studies and describes how body parts work or function
Physiology
The study of the shape and structure of body parts
Anatomy
The tendency of the body’s systems to maintain a relatively constant or balanced internal environment
Homeostasis
The term that indicates all chemical reactions occurring in the body
Metabolism
Keep the body’s internal structure distinct from the external environment
Maintenance of Boundaries
Provides new cells for growth and repair
Reproduction
Occurs when constructive activities occur at a faster rate than destructive activities
Growth
The tuna sandwich you have just eaten is broken down to its chemical building blocks
Digestion
Elimination of carbon dioxide by the lungs and elimination of nitrogenous wastes by the kidneys
Excretion
Ability to react to stimuli; a major role of the nervous system
Responsiveness
Walking, throwing a ball, riding a bicycle
Movement
All chemical reactions occurring in the body
Metabolism
At the cellular level, membranes; for the whole Organism, the skin
Maintenance of Boundaries
Includes carbohydrates, proteins, fats, and minerals
Nutrients
Essential for normal operation of the respiratory system and breathing
Oxygen
Single substance accounting for more than 60% of body weight
Water
Required for the release of energy from foodstuffs
Atmospheric Pressure
Provides the basis for body fluids of all types
Water
When too high or too low, physiological activities cease, primarily because molecules are destroyed or become nonfunctional
Appropriate body temperature

(1)
There are three essential components of all homeostatic control mechanisms: control center, receptor, and effector. The (1) senses changes in the environment and responds by sending information, input, to the (2) along the (3) pathway. The (4) analyzes the input, determines the appropriate response, and activates the (5) by sending information along the (6) pathway. When the response causes the initial stimulus to decline, the homeostatic mechanism is referred to as a (7) feedback mechanism. When the response enhances the initial stimulus, the mechanism is called a (8) feedback mechanism. (9) feedback mechanisms are much more common in the body.
