negative
If your body temperature starts to decline, your body responds by exciting skeletal muscles so that you shiver and your temperature returns to normal. This is an example of ________ feedback.
4,3,1,2
Please match the organ systems with their functions. 1. Cardiovascular 2. Respiratory 3. Muscular 4. Skeletal __Calcium storage and hemopoiesis __Moves the body and generates heat __Transport of nutrients and waste __Exchange of gases
lateral
The axillary region is ______ to the pectoral region.
lateral
The directional term that means "away from the midline of the body" is:
mediastinum
The median space in the thoracic cavity is called the:
lubrication
The primary function of serous fluid appears to be:
a
Thermoreceptors detect body temperature and send impulses to the brain for analysis. If body temperature is low, the brain will signal skeletal muscles to perform brief, repeated contractions to help generate heat. In this example, what is the effector? a) Skeletal muscles b) Brain c) Thermoreceptors d) Body temperature
a
Which of the following is TRUE of positive feedback? a) The change is amplified. b) The change is opposite that of negative feedback. c) Positive feedback mechanisms are independent of negative feedback loops. d) The effector turns off the response.
negative
______ feedback is initiated by wither an increase or a decrease in the stimulus and the end result is to return the stimulus to its normal range or set point. describes most feedback mechanisms in the body
positive
_______ feedback is initiated by a stimulus, and they maintain of increase the activity of the original stimulus.
effector
a molecule cell or organ that brings about a change to the stimulus

receptor
detects a stimulus
abdominopelvic
identify the cavity -houses organs of digestion -inferior boundary is the pelvic girdle -location of the liver -location of the reproductive organs -location of the kidneys
cranial
identify the cavity -houses organs of sensory relay to higher cortical areas
thoracic
identify the cavity -inferior boundary is the diaphragm -houses organs of respiration -location of the heart -includes a superficial serous lining called the paretial pleura -includes the mediastinum -includes the major organ of circulation
control center
interprets input from receptor and initiates change
digestive
name the system -large intestine, -stomach, -esophagus
respiratory
name the system -lungs -trachea
lymphatic
name the system -thymus -tonsils
urinary
name the system -urethra -kidneys
