4 - increased

Puddles (aka The Oregon Duck) was at a pond gathering with lots of both his fellow ducks and his much larger than himself geese friends. Considering his physiology knowledge, he realized that he would be making an accurate analogy by having himself and his fellow ducks be the ____ to those geese as the ___.

interstitial - midsize compartment

Phys Phab Dustin loaned his Magic Shrink Ray to Phys Phab Brittany. She kept the "ion"-size setting and entered her roommate's body. Knowing that she would like to spend some time in the liver and also the brain, she correctly grabs hold of a(n) ___ so she can visit both places on her trip.

Endocrine

A problem-causing feature of some cancer cells is that they can signal themselves to increase their growth rate. The effectiveness of these cancer cells could be reduced the most if a medicine could be given that would prevent communication via

Autocrines

Patient X has frequent shoulder dislocations, overly stretchy skin, and thin blood vessels because the connective tissue in her body is too flexible. Dr. Scarlet told her that her body produces a defective form of a fibrous protein used to hold cells together. Consequently, her connective tissues are too stretchy. Which fibrous protein is defective in Patient X?

Collagen

Brutus Buckeye has been working on an article highlighting the similarities of body organization in humans and the mice he studies. Two correct statements from his paper were that redundancy is a trait of the kidneys ___ the heart and that not all organs contain all ___ types of cells.

But not - four

As a homework assignment for his Physiology Lab, Brutus Buckeye created 2L of a solution containing 3 mol Ca+2, 1 mol HCl, 2 mol MgCl2, and 3 mol NADH. Unfortunately, he spilled half of it when taking it to his TAs desk. His Phys Lab TA correctly measured the turned-in solution's osmolarity as

7 osm

Cells remove integral proteins from the plasma membrane via ___. If this process happens more than ___, then the cell will become ___.

Endocytosis - exocytosis - smaller

The sodium-glucose transporter (SGLT) is a type of ___ and is ___ ATP.

Active transport - dependent on

For a cell to decrease the likelihood of receiving lipophilic messages (i.e., to get less of a response), it should ____ its ____ receptors.

Catabolize - intracellular

The cause of the significant depolarization portion of an action potential is a ___ feedback process which occurs due to an ___.

Positive - influx of sodium

As a fun study break, Phys Phab Grant takes his turn with the Magic Shrink Ray switching the setting at "cell" for size. He decides to spend his visit in the brain. He watches Neuron A receive multiple stimuli at the exact same time. He correctly realizes that this ___ summation could result in a(n) ___ potential if a(n) ___ potential occurs.

Spatial - action - threshold

What is the benefit of hyperpolarization during an action potential?

Allows for unidirectional movement along an axon

When activated, the sympathetic nervous system will use ___ of our fluid compartments for its chemical signals and move the body ___ steady state.

Two - away from

Dr. Gray's Patient X is consistently losing their balance but shows no deficits associated with speaking or memory. Consequently, Dr. Gray expects to find damage localized to their

Cerebellum

Dr. Chris P. Bacon accidentally got a pretty severe sunburn last weekend (aka he got fried). He correctly realizes that he is at risk for further sunburns because he lacks the ___ to detect ___ and thus does not know that he is receiving a lot of UV light.

Adequacy - UV light

Phys Phab Meredith has borrowed the Magic Shrink Ray this week. Instead of taking a trip through a friend's body, she decides to enter an individual who was born with all of his preganglionic axons of identical length. During her trip, Phys Phab Meredith observes that this individual has sympathetic preganglionic neurons ___ activating parasympathetic postganglionic neurons.
