Q

What essential organs are contained in the thoracic cavity?

A

Liver, heart, and lungs

26
Q

What structure separates the thoracic cavity from the abdominal cavity?

A

The diaphragm

27
Q

Does the diaphragm function in the fetus? Explain

A

No because the mother oxidizes the blood

28
Q

What is the function of the thymus gland?

A

Brain structure that receives messages from the sense organs and relays the information to the proper region of the cerebrum for further processing

29
Q

Why do the spongy lungs appear collapsed?

A

They don’t use the lungs at this stage. Instead the umbilical cord is used

30
Q

Suggest a reason for the trachea being so constructed

A

To protect it from getting damaged

31
Q

Describe the appearance of the esophagus

A

Small skinny tube like structure with arteries going through

32
Q

How to the upper and soft palate of the month used in digestion?

A

To help break down the food by chewing and swallowing

33
Q

Where does the needle appear when you run it through the nostril?

A

Back of the throat

34
Q

What is the function of the epiglottis?

A

It switches the use between the esophagus and the larynx

35
Q

System: endocrine
Function: produces hormones

A

Thymus gland

36
Q

System: circulatory
Function: oxygen entering RBC

A

Lungs

37
Q

System: respiratory
Function: releases thyroid hormones into body

A

Thyroid gland

38
Q

System: lymphatic
Function: hold lymphocytes

A

Lymph glands

39
Q

System: digestive
Function: carry food into stomach

A

Esophagus

40
Q

Which is large the right or left ventricle?

A

Right ventricle

41
Q

Can any difference be noted between the right and left atria?

A

The look very similar, no differences seen

42
Q

What difference exists between those two chambers?

A

The atria are flap like and the ventricles feel more firm

43
Q

Into what chamber of the heart do they open?

A

The right atria

44
Q

From what chamber does it arise?

A

The left atria

45
Q

To what structure do the pulmonary arteries lead?

A

The right ventricle

46
Q

Why does this occur?

A

To prevent irregular transmitting of blood between the aorta and pulmonary artery

47
Q

What is the importance of the coronary circulation?

A

To circulate blood throughout the heart

48
Q

What results when coronary circulation is prevented?

A

The heart doesn’t get oxygen

49
Q

In longitudinal section how do the walls of the atria and ventricles differ?

A

Ventricles are thicker and have cardiac muscle because they must be strong enough to push blood away from the heart and through the body. Atria only have to deal with blood flow

50
Q

What is the function of the kidneys ?

A

Producing hormones absorbing minerals, filtering blood and producing orine

51
Q

What substances are carried in the uro general duct?

A

Sperm and urine

52
Q

In which of the previous structures would embryonic or fetal pigs be found?

A

Uterus

53
Q

What are the four tissues?

A

Epithelial - skin
Connective - bone, fat, blood
Muscle - diaphragm
Nerve - brain

54
Q

What are the 2 cavities?

A

Front - thoracic, abdominal

Back - cranial, spinal

55
Q

Carry used blood into the right side of the heart

A

Superior (upper) and Interior (lower) vena cava

56
Q

Receives blood for the superior and interior venas cavas

A

Right atrium

57
Q

Is a powerful, muscled part of your heart that receives blood from the right atrium, then bumps it to the pulmonary artery

A

Right ventricle

58
Q

Splits into two branches that carry blood from the right ventricle of the heart to the lungs

A

Pulmonary artery

59
Q

Receives blood from the lungs and pumps it to the left artery

A

Left atrium

60
Q

Then pumps the blood through the aorta

A

Left ventricle

61
Q

Is a curved blood vessel that becomes the dorsal aorta

A

Aortic arch

62
Q

Blood travels to the bottom half of the body
