protects and supports body organs; provides a framework the muscles use to cause movement

34
Q

skeletal body function key structures

algor mortis

A

body begins cooling/heating process to match the surrounding temp and it starts immediately after death until 24 hours

36
Q

rigor mortis

A

stiffness in the joints first in the head and then the neck and begins 2-4 hours after death and then fades 36-48 hours

blood pooling when blood settles or collects on parts of body on floor and starts within 2 hours

38
Q

corneal clouding

A

corneas of the eyes become milky or cloudy within the first few hours of death

39
Q

decomposition

A

body turns green and may swell/bloat as bacteria breakdown tissue and releases gas

40
Q

insect activity

A

can provide clues as to how long a person has been deceased. eggs, larva, or full grown bugs provide time stamp and starts within 1-145 hours

41
Q

glastier equation

(98.4 - rectal temp)/1.5 = approx hours since death

42
Q

ambient temp

A

air temp of surroundings

43
Q

how does ambient temp affect rate of cooling

A

if the temp is cold, the body cools faster, if its hot, the body heats up faster

44
Q

toxin vs toxicant

A

toxin - poison produced by a living organism
toxicant - manmade, harmful substance

45
Q

nutrient vs molecule

A

nutrient - substance body needs to maintain health
molecule - group of atoms held together by chemical bonds

46
Q

metabolism vs digestion

A

digestion - process of breaking down food into nutrients and molecules
metabolism - chemical reaction process to build more complex molecules

47
Q

chemical reaction

A

process where atoms and/or molecules are rearranged to transform matter

48

1- oral cavity
2 - esophogas
3 - stomach
4 - small intestine

49
Q

presumptive test

A

quick tests that indicate if a type of substance is presented but cannot specifically identify a substance

50
Q

confirmatory test

A

specific tests that can determine the exact identity and composition of a substance by pinpointing certain properties of that substance

51
Q

negative vs positive control

study the microscopic structure of tissues

53
Q

largest to smallest

A

organ system
organ
tissue
cell

54
Q

central nervous system (cns)

A

the brain processes info, makes decisions about what to do, and sends signals back using peripheral system to bring about a specific change (also uses spinal cord think CENTRAL nervous system uses spinal CHORD)

55
Q

peripheral nervous system (pns)

A

nerves bring info from outside and within the body to the cns for processing

56
Q

temporal lobe

A

used for processing language and storing info in long-term memory (the bottom of the brain)

57
Q

parietal lobe

A

crucial in integrating sensory ad visual info (the top right of the brain)

58
Q

occipital lobe

A

recieves and processes sensory nerve impulses from eyes (below the parietal lobe)

59
Q

frontal lobe

A

responsible for planning and organizing incoming info and controls behavior and emotions (top left of brain think when you’re reading you read from the left aka front of the paragraph)

60
Q

nervous tissue

A

found in the spinal cord and brain made up of neurons that work to receive, interpret, and respond to signals

61
Q

epithelial tissue

A

found lining outer surfaces organs/blood vessels/humans, works to absorb secrete, protect and sense

62
Q

muscle tissue

A

found attatched to bones in the walls of organs or walls of heart and provides ability to contract

63
Q

connective tissue

A

supports/connects other tussye types in the body, holds organs in place, attaching muscles to bones, and links bones with joints

64

between RV and pulmonary artery

66
Q

mitral/bicuspid valve

A

between LV and LA

67
Q

aortic valve

A

between LV and aorta

68
Q

superior vena cava

A

sends blood TO HEART, recieves blood from top half of body, and gives blood to RA

69
Q

inferior vena cava

A

sends blood TO HEART, recieves blood from lower half of body, and gives blood to RA

70
Q

A

sends blood AWAY FROM HEART, recieves blood from RV, gives blood to lungs

71
Q

pulmonary viens

A

sends blood TO HEART, recieves blood from lungs, and then gives it to LA

72
Q
