Physics of the Human Body Final
Review PHYS 1110 Questions with
Guaranteed Pass Solutions.
Twin Paid Production - Answer X-rays that can be used to treat cancer. Utilizes Einstein's
equation E=mc2 to create matter and antimatter particles that will destroy each other and kill
tumors.
Purpose of our bones: - Answer Support, Hearing, Storage of Calcium, Movement, NOT VOICE
PRODUCTION
Why did humans evolve to stand upright? - Answer To breathe better to run longer!
Periosteum - Answer A dense fibrous membrane covering the surface of bones (except at their
extremities) and serving as an attachment for tendons and muscles. Gives the bone extra
strength.
Osteoperosis - Answer Bone mass is lost because of lost calcium.
How does the body protect itself from injury when falling? - Answer Bending the knees, having
discs in the spine, twisting of the fibula.
Traumatic Injury to the Body is caused by - Answer How quickly a person stops, change in
momentum, impulse!
Osteoporosis is a loss of bone - Answer Mass, not density
Problems caused by osteoperosis - Answer Spontaneous Fractures, Brittle Bones, Less Calcium
in Bones
Signs of a Concussion - Answer Memory Loss, Poor Thinking, Dizziness, Nausea, Headache
Two compounds found in bones + purpose - Answer Collagen: flexible like a chunk of rubber
and gives bones strength
,Do helmets always protect the head from injury? - Answer Not always at high speeds
Most common contact sport injury - Answer Concussion
Difference between a horse's stride and a human's - Answer Humans have longer stride, more
efficient as uses less energy
Bone - Answer A living tissue that has nerves and requires blood
How have humans evolved to stand upright and run better? - Answer Large butts help to
balance the body upright when leaning forward to run.
Achilles tendon evolved to help.
When we have an x-ray taken of our body, x-rays pass through our bones and tissues. Bones
absorb the x-rays, while muscles and other tissues allow the x-rays to pass through. This allows
for imaging to occur. The name for this effect that allows imaging is ____________. - Answer
The photoelectric effect
MRI scans use - Answer powerful magnets
MRI scans are best for - Answer Imaging muscles and tendons
MRI scans look for - Answer Hydrogen Atoms
Bone Marrow - Answer Red and yellow: red makes blood cells and the yellow produces fat
Purpose of discs in between vertebrae in spine - Answer Allow for motion of the spine- flexion
and extension
Function as "shock absorbers" that protect the brain, spine, and other structures
sudden impact of two objects in motion is called a(n) ________and is shown by the sudden
change in__________. - Answer impulse, momentum
, Purpose of the lungs - Answer O2 and CO2 gas exchange
Moistening of the air
Yawning
Alveoli - Answer tiny sacs of lung tissue specialized for the movement of gases between air
and blood, like interconnected bubbles. surfactant coats the inside to decrease surface tension.
Number of alveoli remains the same throughout life although the shape may change.
pneumothorax - Answer air in the pleural cavity caused by a puncture of the lung or chest wall
Cilia - Answer Hairlike projections that extend from the plasma membrane and are used for
locomotion. They MOVE PARTICLES OUT OF THE AIRWAYS
Oxygen binds to hemoglobin at 4 sites on the 4 different subunits. Which is located at these
sites? - Answer Iron
Three steps of our metabolism - Answer 1. Glycolysis- happens immediately to give an instant
burst of energy. Produces Pyruvate
2. Kreb's Cycle- produces electrons
3. Electron Transport Chain- produces ATP.
Stored form of glucose - Answer Glycogen
Exercise metabolic rate (EMR) - Answer the energy expenditure that occurs during exercise,
the total amount of energy a person uses throughout the day
Basal metabolic rate (BMR) - Answer the rate at which the body burns energy when the
organism is resting
Oxygen Debt - Answer When a person has to run very fast, the body turns pyruvate into lactic
acid to create a small amount of ATP. This will not work for very long (maybe for a minute or two
at the most).
When a person exercises, blood is shifted from the _______ to the ______. This allows people
