to solidify

Question 1

Boyles law

Answer 1

Pressure and volume have an inverse relationship

Question 2

Dalton’s law

Answer 2

total pressure (Add all the partial pressures to get total pressure)

Question 3

Henry’s law

Answer 3

gases will enter a solution (usually water) relative to their partial pressure. (Eg. if O2 is in the air at .3 mmHg, it will enter water at .3 mmHg).

Question 4

Fick’s law

Answer 4

increase surface area = increased diffusion, increased membrane thickness = decreased diffusion

Question 5

Air pathway

Answer 5

Trachea, bronchi, lobar bronchi, bronchiolis, alveolar duct, alveoli

Question 6

Cephalic digestion phase

Answer 6

salivation, looking at food, activated by parasympathetic nervous system. (Think of a cephalopod’s big ass head)

Question 7

Gastric digestion phase

Answer 7

when food is in the stomach region, know of the food pathway

Question 8

intestinal digestion phase

Answer 8

when food is in the intestinal region

Question 9

intestinal I cells

Answer 9

• activated by lipids and proteins
• releases CCK to increase bile production and secretion

Question 10

Intestinal S cells

Answer 10

• activated by acidity
• releases secretin to pancreas to calm down acidity

Question 11

Intestinal K cells

Answer 11

• activated by glucose
• releases GIP into beta cells of pancreas in order to release insulin
• directs the glucose to liver

Question 12

where is Bile produced and stored

Answer 12

Produced in liver, stored in gallblatter

Question 13

what are the filters within the kidneys called?

Answer 13

nephrons

Question 14

Afferent vs Efferent

Answer 14

Afferent = in, Efferent = out

Question 15

blood filtration process

Answer 15

• Within the nephrons, capillaries expel blood into the bowman’s capsule. From there it procedes to (Everything is part of bowman’s capsule):
• PCT (Proximal convoluted tubule)
• Thin descending loop
• Loop
• Thin ascending loop
• Thick ascending loop
• DCT (Distal convoluted tubule)
• papillary duct
• ureter

Question 16

glottis

Answer 16

The opening of the trachea, vocal area

Question 17

epiglottis

Answer 17

Flap over trachea that prevents foreign objects like food from entering

Question 18

Food pathway process

Answer 18

When food hits the stomach it:
- Food hits the stretch receptors
- Stretch receptors activates the gastrin
- Gastrin receptors on parietal activates HCL (Acetylcholine from the parasympathetic nervous system also activates parietal HCl, mostly during cephalic phase)
- Gastrin activates pepsinogen as well
- HCL activates the goblet cells to release mucus
