Q

WHAT IS “ANATOMY”?

A

THE SCIENCE OF BODY STRUCTURES AND THEIR INTERRELATIONSHIPS. FIRST STUDIED BY DISSECTION DISSECTION IS THE CAREFUL CUTTING APART OF BODY STRUCTURES TO STUDY THEIR RELATIONSHIPS. TODAY A VARIETY OF IMAGING TECHNIQUES ADVANCE ANATOMICAL KNOWLEDGE. (ANA = APART + TOMY = PROCESS OF CUTTING).(DIS = APART + SECTION = ACT OF CUTTING).

Q

WHAT ARE EXAMPLES OF STRUCTURE BEING RELATED TO FUNCTION (ANATOMY BEING RELATED TO PHYSIOLOGY)?

A

1 - WALLS OF ALVEOLI VERY THIN, THEREFORE RAPID MOVEMENT OF O2 INTO BLOOD.

2 - LINING IN URINARY BLADDER MUCH THICKER THAN IN ALVEOLI TO PREVENT ESCAPE OF URINE INTO PELVIC CAVITY, YET CAN STRETCH CONSIDERABLY TO COLLECT URINE.

20
Q

WHAT IS RENAL PHYSIOLOGY?

A

THE STUDY OF THE FUNCTIONS OF THE KIDNEYS.

21
Q

WHAT IS EXERCISE PHYSIOLOGY?

A

THE STUDY OF CHANGES IN CELL AND ORGAN FUNCTIONS AS A RESULT OF MUSCULAR ACTIVITY.

22
Q

WHAT IS PATHOPHYSIOLOGY?

A

THE STUDY OF FUNCTIONAL CHANGES ASSOCIATED WITH DISEASE AND AGING.

23
Q

WHAT TYPES OF TISSUE ARE IN THE STOMACH?

A

THREE LAYERS OF TISSUE IN THE WALLS

1 - OUTER COVERING IS THE SEROUS MEMBRANE – BOTH AN EPITHELIAL AND CONNECTIVE TISSUE WHICH DECREASES FRICTION WITH OTHER ORGANS

2 - UNDERNEATH THAT – (SMOOTH) MUSCLE LAYER WHICH CONTRACT, CHURN, MIX, PUSH CONTENTS INTO NEXT DIGESTIVE ORGAN (SMALL INTESTINE)

3 - INNERMOST LIVING – EPITHELIAL TISSUE LAYER

Auscultation
Percussion

34

A 
Integumentary 
Skeletal
Muscular
Endocrine
CV
Digestive
Urinary
Lymphatic + Immune
Respiratory
Reproductive
35
Q

What are the most import life processes in the human body?

A

Metabolism ( including catabolism and anabolism)
Responsiveness
Growth
Differentiation
Reproduction (including new cells for tissue growth, repair or replacement as well as production of a new individual)

36
Q

What is the ECF within blood vessels?

A

Blood plasma

37
Q

What is the ECF in lymphatic vessels?

A

Lymph

38
Q

ECF in and around brain?

A

Cerebrospinal fluid

39
Q

ECF in joints?

A

Synovial fluid

40
Q

ECF of eyes?

A

Aqueous humour

Vitreous body

41
Q

What is an autopsy?

A

Post Mortem exam
Dissection internal organs
To confirm/determine cause of death
“Seeing for oneself”

42
Q

What is a diagnosis?

A

The science and skill of distinguishing one disorder to disease from another. Based on -
symptoms (from a med history )
signs
medical history ( chief complaint, history of present illness, past med problems, family medical problems, social history, review of symptoms)
physical exam (inc. non invasive techniques and measurement of vital signs and lab tests )
“Through knowing”

43
Q

What are the symptoms vs signs?

A 
Symptoms —
Subjective 
Headache
Nausea
Anxiety

Signs—

Objective
Measureable
Observable

Anatomical examples
Swelling
Rash

Physiological examples
Fever
High BP
Paralysis

44
Q

What is a disorder?

A

Any abnormality of structure or function

45
Q

What is a disease?

A

An illness with set signs and symptoms

It can be local or systemic

46
Q

What are the two main types of body fluid (plus one subtype)?

A

ICF
ECF - including interstitial fluid - fills the narrow spaces between cells and is aka “internal environment” of body because proper functioning of body cells depends on interstitial fluid composition surrounding them

47
Q

Why autopsy?

A 
To confirm/determine cause of death
Can uncover undetected diseases
Determine extent injuries
Explain how contributed
Reveal conditions affecting offspring or siblings (congenital heart defects)
Info about disease
Stats
Educate health students
Resolving beneficiaries/insurance company disputes
Legal req eg. Criminal investigation
