Question 8

A torn tendon sidelines athletes for long periods of time because the tissues possess less vascular tissue than bone.

Accepted Answer

A) True 
 B)False

Question 9

Blood pressure is carefully regulated by a negative feedback control system in the body. When the blood pressure falls below a set point, this decreased pressure is detected by baroreceptors (pressure receptors) in the aorta and carotid arteries. These receptors send signals to a region of the brain known as the medulla oblongata. This region of the brain integrates incoming signals and sends signals to the heart to increase the strength of contractions and to the blood vessels, to constrict arterioles so as to increase the blood pressure, returning it to normal. Based on this information, identify each of the parts of this control system:
a) controlled variable
b) sensor
c) control center
d) effector(s)

Accepted Answer

The controlled variable in this system i

Question 16

Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point.

These homeostatic responses are examples of
