Organ Systems + Homeostasis Flashcards
Provide the components of a homeostatic system to the correct description:
Effector, sensors, feedback loop, control centre
Effector = respond in some way to restore homeostasis
Sensors = detect a change in the internal environment
Feedback loop = communication between the sensor, control centre and effector
Control centre = integrate the sensory information
Provide the following with the correct definition:
Na+, lipid, protein, Cl-
Na+ = electrolyte Lipid = molecule Protein = molecule Cl- = electrolyte
Match the following biological parameter to their correct classification:
Blood temperature, blood pressure, blood volume, blood pH, blood sodium, blood glucose
Blood temp = physical Blood pressure = physical Blood volume = physical Blood pH = chemical Blood sodium = chemical Blood glucose = chemical
Match these organs to their organ system:
Ovary, gall bladder, diaphragm, cerebellum, vena cava
Ovary = reproductive Gall bladder = digestive Diaphragm = respiratory Cerebellum = nervous Vena cava = cardiovascular
Choose the correct label for the homeostatic range for each of the following:
Blood glucose, blood temperature,
Blood volume, blood calcium
Blood glucose = wide
Blood temp = narrow
Blood volume = wide
Blood calcium = narrow
