What is Homeostasis?
Describes the body’s ability to maintain relatively stable conditions even though the outside world is continuously changing.
What is the Negative Feedback mechanism?
The net effect of the response to the stimulus is either shut off the original stimulus or reduce its intensity.
What is the Positive Feedback mechanism?
Rare in the body; but will increase the original disturbance (stimulus) and to push the variable farther from its original value.
Having a fever & body starts sweating is an example of what feedback mechanism?
Negative Feedback
Taking medicine to reduce temp. body & trying to go back to normal body temp. to maintain homeostasis, is an example of what feedback mechanism?
Negative Feedback
Blood Clotting is an example of what feedback mechanism?
Positive Feedback
Giving Birth is an example of what feedback mechanism?
Positive Feedback
TOWARD the head or toward the LOWER PART of structure or the back; ABOVE
Superior (cranial or cephalic)
AWAY from the head or TOWARD THE LOWER PART of a structure or the body; BELOW
Inferior (caudal)
Toward or at the front of the body; IN FRONT OF
Anterior (Ventral)
Toward or at the backside of the body; BEHIND
Posterior (Dorsal)
Toward or at the MIDLINE of the body; on the INNER side of
Medial
Away from the midline of the body; on the OUTER side of
Lateral
Close to the origin of the body part or the point of attachment of a limb to the body trunk
Proximal
Farther from the origin of a body part or the point of attachment of a limb to the body trunk
Distal
TOWARD or at the body surface
Superficial (external)
AWAY from the body surface; more internal
Deep
The external covering of the body, or the skin, including the hair and fingernails.
Integumentary system
Responsible for body movements, stabilizing joints, and generating heat
Muscular system
Is the primary control system of the body, and provides for higher mental function and emotional expression, maintains homeostasis, and regulates the activities of muscles and glands.
Nervous System
Is the second control system of the body, and m releases chemicals called hormones that regulate complex body processes
Endocrine System
Delivers oxygen and nutrients to the body tissues and carries away wastes such as carbon dioxide via blood
Cardiovascular System
Carries excess interstitial fluid from tissues back to cardiovascular circulation and provides locations for immune cells to monitor the body
Lymphatic System
Provides oxygen to the body, disposes of carbon dioxide, and helps reguate blood pH.
Respiratory System
Breaks down the food you eat into nutrients needed for metabolic processes, such as making ATP, and rids the body of materials that cannot be used, such as fiber.
Digestive System
Filters nitrogenous wastes from the blood and helps regulate water, electrolyte, and acid-base balances.
Urinary System
The reproductive organs of men and women produce gametes and also contribute to the development of secondary sex characteristics.
Reproductive System
