Q1 Beginner 1 pts

According to the video, what is urea and where is it produced? Video Reference:
"the main waste product you need to know about is urea which is made in the liver during the process ..."

Timestamp: 0:45

A waste product made in the liver during deamination A useful ion made in the kidneys A hormone produced by the pituitary gland A protein filtered by the nephrons

Q2 Beginner 1 pts

The speaker mentions that each kidney contains approximately how many nephrons? Video Reference:
"inside each of our two kidneys are around a million of these structures called nephrons..."

Timestamp: 3:00

Around a thousand Around a million Around ten thousand Around a hundred thousand

Q3 Intermediate 2 pts

According to the video, what happens to cells when there is too much water in the body? Video Reference:
"if you have too much water in your body the water will diffuse into your cells by osmosis causing th..."

Timestamp: 2:00

They shrink due to water loss Water diffuses into them by osmosis, causing them to swell and possibly burst They produce more urea They release ADH hormone

Q4 Intermediate 2 pts

In the kidney filtration process described in the video, which substances are NOT absorbed by the tubules? Video Reference:
"these kidney tubules absorb anything small so water glucose amino acids urea pretty much everything ..."

Timestamp: 3:10

Water and glucose Amino acids and urea Proteins and cells Ions and water

Q5 Beginner 1 pts

The video explains that ADH stands for what? Video Reference:
"the signals tell the pituitary gland to release a hormone called adh or antidiuretic hormone into th..."

Timestamp: 4:30

Anti-dehydration hormone Antidiuretic hormone Anti-detection hormone Amino-digestive hormone

Q6 Intermediate 2 pts

True or False: According to the video, glucose is completely reabsorbed by the kidneys because it is always useful. Video Reference:
"because glucose is always useful we reabsorb all the glucose..."

Timestamp: 3:30

True

False

Q7 Intermediate 2 pts

According to the video, which brain structure detects the concentration of water in the bloodstream? Video Reference:
"inside the brain there's a structure called the hypothalamus which detects the concentration of wate..."

Timestamp: 4:10

The pituitary gland The hypothalamus The cerebellum The medulla

Q8 Beginner 1 pts

True or False: The speaker states that we lose ions naturally during sweating, which is why sweat tastes salty. Video Reference:
"we lose some ions naturally during sweating which is why sweat tastes a bit salty..."

Timestamp: 1:30

True

False

Q9 Advanced 3 pts

"to use an analogy you can kind of think about it like cleaning out your house by first of all throwi..."

Timestamp: 3:40

Like a water filter removing impurities Like cleaning out your house by throwing everything outside and bringing back only what you want Like a factory assembly line sorting products Like a security checkpoint screening passengers

Q10 Advanced 3 pts

The video explains that water regulation through ADH is an example of what type of biological process? Video Reference:
"this whole process of water regulation is an example of a negative feedback loop because the body is..."

Timestamp: 5:50
