Q

How do you calculate minute respiratory volume?

A

Tidal volume (respiratory rate) = minute respiratory volume.

21
Q

How do you calculate the partial pressure of a gas in the air?

A

% in air (total pressure) = partial pressure of gas.

22
Q

What is the respiratory center of the brain?

A

The medulla

23
Q

Where are chemoreceptors for the partial pressure of oxygen

A

Carotid and aortic bodies.

24
Q

What part of the nephron is involved in making urine of varying concentrations?

A

The loop of Henle

25
Q

What is the capillary bed in the kidney?

A

The glomerulus

26
Q

What is the functional unit of the kidney?

A

The nephron

27
Q

Does filtrate pass through the podocyte plasma membrane?

A

No.

28
Q

Where is the sodium potassium ATPase pump located in the kidney?

A

The basolateral membrane of the tubular cells.

29
Q

What is absorbed by the proximal convoluted tubule?

A

Sodium, amino acids, and glucose.

30
Q

What is Tm?

A

The maximum rate a substance can be reabsorbed by carrier molecules.

31
Q

Where is water reabsorption under the influence of ADH controlled?

A

The distal convoluted tubule and the collecting tubule.

32
Q

What is plasma clearance?

A

Measure of the rate a substance is

cleared from plasma by the kidney.

33
Q

Where is the greatest amount of water held in the body?

A

The intracellular fluid (in the cells)

34
Q

What happens to the osmolarities of the extracellular fluid and the intracellular fluid when large amounts of fresh water are consumed?

A

The osmolarities decrease (concentration solutes goes down as solvent volume increases)

35
Q

Why is exracellular fluid volume so carefully regulated?

A

It has an impact on blood pressure because blood is included in the ECF

36
Q

What happens when there is a drop in arterial blood pressure?

A

GFR decreases, aldosterone is released, renin is released, and sodium reabsorption increases.

37
Q

What is a cause of metabolic acidosis?

A

Severe diarrhea.

38
Q

What is the order of the digestive tract wall from the lumen to th external surface?

A

mucosa, submucosa, muscularis externa, serosa.

39
Q

How does gastric reflux occur?

A

Material flows backwards from the stomach through the lower esophageal sphincter (cardiac sphincter).

40
Q

What is the major chemically digestive activity happening in the stomach?

A

Digestion of protein by pepsin, a protease.

41
Q

What are the different digestive secretions?

A

Enzymes, bile, mucus, buffers.

42
Q

What are included in the exocrine secretions of the pancreas?

A

Bicarbonate, proteases, carbohydrates, and lipases.

43
Q

Does the gall bladder produce bile?

A

No.

44
Q

What does the pancreas do?

A

Secrete bicarbonate to neutralize the acidic contents of the stomach.

45
Q

How is secretion of pancreatic digestive enzymes regulated?

A

Hormonally.

46
Q

What does the ileocecal valve do?

A

Prevent backflow of chyme from the small intestine to the large intestine.

47
Q

Does digestion occur in the colon?

A

No.

48
Q

Do colonic bacteria digest cellulose for their own benefit?

A

Yes.
