Helps you in your roles as a parent, spouse, partner, friend, colleague and caregiver

107
Q

For whom would an appreciation of the structural characteristics of the human heart come more easily: an alien who lands on Earth, abducts a human, and dissects the heart, or an anatomy and physiology student performing a dissection of the heart on her very first day of class? Why?

A

A student would more readily appreciate the structures revealed in the dissection. Even though the student has not yet studied the workings of the heart and blood vessels in her class, she has experienced her heart bearing every moment of her life, has probably felt her pulse, and likely has at least a basic understanding of the role of the heart in pumping blood throughout her body. This understanding of the heart’s function (physiology) would support her study of the heart’s form (anatomy).

108
Q

Explain why the smell of smoke when you are sitting at a campfire does not trigger alarm, but the smell of smoke in your residence hall does.

A

When you are sitting at a campfire your sense of small adapts to the smell of smoke. Only if that smell were to suddenly and dramatically intensify would you be likely to notice and respond. In contrast, the smell of even a trace of smoke would be new and highly unusual in your residence hall, and would be perceived as danger.

109
Q

Identify three different ways that growth can occur int he human body

A

Growth can occur by increasing the number of existing cells, increasing the size of existing cells, or increasing the amount of non-cellular material around cells.

110
Q

When you open a bottle of sparkling water, the carbon dioxide gas in the bottle form bubbles. If the bottle is left open, the water will eventually “go flat.” Explain these phenomena in terms of atmospheric pressure.

A

In a sealed bottle of sparkling water, carbon dioxide gas is kept dissolved in the water under a very high pressure. When you open the bottle, the pressure of the gas above the liquid changes from artificially high to normal atmospheric pressure. The dissolved carbon dioxide gas expands, and rises in bubbles to the surface. When a bottle of sparkling water is left open, it eventually goes flat because its gases continue to move out of solution until the pressure in the water is approximately equal to atmospheric pressure.

111
Q

On his midsummer trek through the desert, Josh ran out of water. Why is this particularly dangerous?

A

The primary way that the body responds to high environmental heat is by sweating; however, sweating requires water, which comes from body fluids, including blood plasma. If Josh becomes dehydrated, he will be unable to sweat adequately to cool his body, and he will be at risk for heat stroke as his blood pressure drops too much from the loss of water from the blood plasma.

112
Q

Identify the four components of a negative feedback loop and explain what would happen if secretion of a body chemical controlled by a negative feedback system became too great.

A

The primary way that the body responds to high environmental heat is by sweating; however, sweating requires water, which comes from body fluids, including blood plasma. If Josh becomes dehydrated, he will be unable to sweat adequately to cool his body, and he will be at risk for heat stroke as his blood pressure drops too much from the loss of water from the blood plasma.

113
Q

What regulatory processes would your body use if you were trapped by a blizzard in an unheated, uninsulated cabin in the woods?

A

Any prolonged exposure to extreme cold would activate the brain’s heat-gain center. This would reduce blood flow to your skin, and shunt blood returning from your limbs away from the digits and into a network of deep veins. Your brain’s heat-gain center would also increase your muscle contraction, causing you to shiver. This increases the energy consumption of skeletal muscle and generates more heat. Your body would also produce thyroid hormone and epinephrine, chemicals that promote increased metabolism and heat production.

114
Q

In which direction would an MRI scanner move to produce sequential images of the body in the frontal plane, and int which direction would an MRI scanner move to produce sequential images of the body in the sagittal plane?

A

If the body were supine or prone, the MRI scanner would move from top to bottom to produce frontal sections, which would divide the body into anterior and posterior portions, as in “cutting” a deck of cards. Again, if the body were supine or prone, to produce sagittal sections, the scanner would move from left to right or from right to left to divide the body lengthwise into left and right portions.

115
Q

If a bullet were to penetrate a lung, which three anterior thoracic cavities would it enter, and which layer of serous membrane would it encounter first?

A

The bullet would enter the ventral, thoracic, and pleural cavities, and it would encounter the parietal layer of serous membrane first.

116
Q

Which medical imaging technique is most dangerous to use repeatedly, and why?

A

Ct scanning subjects patients to much higher levels of radiation than X-rays, and should not be performed repeatedly.

117
Q

Explain why ultrasound imaging is the technique of choice for studying fetal growth and development.

A

Ultrasonography does not expose a mother or fetus to radiation, to radiopharmeceuticals, or to magnetic fields. At this time, there are not known medical risks of ultrasonography.
