Q

The autonomic nervous system will innervate the heart and control the rate of the contractions

A

True
Sympathetic will increase it by influencing the SA node, AV node, and cardiac muscle
Parasympathetic slows it down with the SA and AV node.

27
Q

Veins have little to no pressure but have continued flow towards the heart.

A

True

28
Q

Viscosity is something we keep at homeostasis

A

True

It’s set at a certain level, we regulate it.

29
Q

Lymphatic tissue is a new tissue recently discovered

A

False

its a collection of lymphatic cells within one of the other tissue types.

30
Q

The thoracic duct starts below the diaphragm

A

True

starts as cisterna chili

31
Q

Lymphatic capillaries are blind-ended capillaries that start around our blood capillaries

A

True

a difference in lymphatic capillaries have large gaps between endothelial cells

32
Q

For immune clearance to occur you need an antibody

A

True

33
Q

In cellular immunity, T-cells will actively destroy pathogens

A

True

34
Q

B-cells are part of humoral immunity, they wander around the lymphatic system actively seeking and destroying pathogens

A

False

35
Q

The antigen is the smaller part of the epitome

A

False

The epitome is the smallest part of the antigen. The epitome is what we respond to.

36
Q

B-cells can function as APCs

A

True

37
Q

T helper cell is the most important immune cells because it plays a role in specific and non-specific defenses

A

True

38
Q

B-cells are responsible for making antibodies as part of humoral immunity

A

False

39
Q

Plasma cells are responsible for making antibodies as part of humoral immunity

A

True

40
Q

The entire respiratory system is involved with gas exchange

A

False

A lot of it is just moving air

41
Q

Epiglottis, thyroid, and cricoid are composed of hyaline cartilage

A

False

Epiglottis is elastic cartilage

42
Q

In gas exchange, the gas only crosses one cellular membrane

A

False

43
Q

E-neurons physically make muscles contract in order for you to expire

A

False

44
Q

The VRG can be influenced by both the DRG and PRG to change respiratory cycle

A

True

45
Q

When we inspire the pressure on the external environment is greater than the pressure in the lungs.

A

True

46
Q

O2 and CO2 are soluble in water

A

True

47
Q

For systemic gas exchange to happen oxygen unloads first

A

False

48
Q

For alveolar gas exchange CO2 comes out first

A

False

O2 has to go in first

49
Q

Juxtamedullary nephrons are used to make normal dilute urine

A

False

They make concentrated urine

50
Q

In DCT we have urine

A

False

there we have filtrate

51
Q

The paratenium is similar to the pericardial sac and the pleura in thoracic cavity

A

True

52
Q

The lower esophageal sphincter is a true sphincter

A

False

53
Q

The gastric pits produce the gastric juice

A

True

HCl and digestive enzymes

54
Q

The parietal cells make HCl acid via the use of CAH

A

55
Q

We use ATP in production of HCl acid

A

True

56
Q

The taenia coli is the longitudinal layer of the muscularis externa

A

True

57
Q

Pepsinogen digests protein

A

False

Pepsinogen is an inactive enzyme, it has to be pepsin

if not present we go into anaerobic fermentation (lactid acid)

60
Q

In order to make ATP in the electron transport chain we rely on chemiosmotic mechanism

A

True

61
Q

Glycogenesis is the breakdown of glycogen into glucose

A

False

that would be glycogenolysis

In order for the mesonephric ducts to develop nothing else has to be added or expressed

A

False

SRY gene has to be expressed

64
Q

The countercurrent heat exchanger is going to cool the blood on his way down tot he testes

A
