26
Q

Receptors

A

Send nerve impulses or chemical signals to control Center

27
Q

Control Center

A

Receive the input and provide nerve impulses or chemical signals to effectors

28
Q

Effectors

A

Bring about a change

29
Q

Interstitial fluid

A

ECF that fills the narrow spaces between cells

30
Q

Negative feedback system

A

reverses a change in the controlled condition. Brings you back to homeostasis

31
Q

Positive feedback system

A

tends to strengthen or reinforce a change of the body’s controlled conditions, response, will be exaggerated, stops when stimulus isn’t there

32
Q

When homeostasis is disrupted it may result in

A

Disease
Disorder
Death

33
Q

Factors that can affect your health

A

genetic make-up, the air you breathe, the food you eat, and the thoughts you think

34
Q

Disorder

A

Any abnormality of structure or function

35
Q

Disease

A

More specific term for an illness characterized by recognizable set of signs and symptoms

36
Q

Signs

A

manifestation of a disease that is noted by an observer
(e.g., temperature 39°C, joint looks red and swollen)

37
Q

Symptoms

A

Subjective complaint made by person with disease (e.a. “I feel hot. “It hurts)

38
Q

Head (cephalic)

A

Skull and face

39
Q

Neck (cervical)

A

Supports the head and attaches to the trunk

40
Q

Trunk (thoracic, abdominal, pelvic)

A

Chest, abdomen, and pelvis

41
Q

Upper limb

A

Attached to trunk

42
Q

Lower limb

A

Attaches to trunk

43
Q

Supine

A

Laying on back

44
Q

Prone

A

Laying on belly

45
Q

Cranial cavity

A

Formed by cranial bones and contains brain

46
Q

Vertebral cavity

A

Formed by vertebral column and contains spinal cord and the beginnings of spinal nerves

47
Q

Thoracic cavity

A

Chest cavity; contains pleural and pericardial cavities and the mediastinum

48
Q

Pleural cavity

A

A potential space between the layers of the pleura that surrounds a lung

49
Q

Pericardial cavity

A

A potential space between the layers of the pericardium that surrounds the heart

50
Q

Mediastinum

A

Central portion of thoracic cavity between the lungs; extends from sternum to vertebral column and from first rib to diaphragm; contains heart, thymus, esophagus, trachea, and several large blood vessels

51
Q

Abdominopelvic cavity

A

Subdivided into abdominal and pelvic cavities

52
Q

Abdominal cavity

A

Contains stomach, spleen, liver, gallbladder, small intestine, and most of large intestine; the serous membrane of the abdominal cavity is the peritoneum

53
Q

Pelvic cavity

A

Contains urinary bladder, portions of large intestine, and internal organs of reproduction

54
Q

Membranes

A

Simple organs

55
Q

 mucus membrane

A

Directly open to the outside, mouth, anus, nose

56
Q

Serous membrane

A

thin, double-layered membranes that covers the viscera within the thoracic and abdominal cavities and also lines the walls of the thorax and abdomen, reduces friction

57
Q

Pleura

A

Contains right pleura cavity, parietal pleura, and visceral pleura. Covers lungs

58
Q

Pericardium

A

Contains parietal pericardium, pericardial cavity, and visceral pericardium, covers the heart

59
Q

Peritoneum

A

covers many of the abdominal organ

60
Q

Retroperitoneal

A

classification some organs are given because they are not surrounded by the peritoneum, rather, they are posterior to it

61
Q

Aging

A

Progressive decline in the body’s ability to restore homeostasis

62
Q

Apoptosis

A

Programmed cell death

63
