Q

veins 4

A

thin-walled blood vessels that are less Elastic than arteries

contain cup-like valves that keep blood flowing in one direction to the heart and prevent back flow

carry blood containing waste product back to heart and lungs for cleaning and to pickup oxygen

located closer to skin surface

Q

blood 3

A

nutritive fluid circulating through system

considered connective tissue because it connects body systems together

brings oxygen, nutrients and hormones and removing waste products

Q

functions of blood 5

A

carries water, oxygen, nutrition, and minerals to all cells and tissues

carries away carbon dioxide and waste product to be eliminated through lungs, skin and kidneys

equalizes body temperature- protecting from extreme heat and cold

protects from harmful bacteria and infection - WBC

closes injured tiny blood vessels by clotting preventing blood loss

Q

red blood cells 1

A

carries oxygen to body cells

16
Q

white blood cells 1

A

perform the function of destroying disease causing microorganisms

17
Q

platelets 1

A

contribute to blood clotting process which stops bleeding

18
Q

plasma 3

A

fluid apart of blood

90% water and contains proteins, sugars and minerals

acts as delivery system, carrying vital components (nutrients, hormones, minerals) to cells and take away waste

19
Q

common carotid arteries 2

A

main source of blood supply to head, face and neck

on either side of neck each divided into internal and external branch

20
Q

veins of head, face and neck 2

A

internal and external jugular vein on each side of the neck

21
Q

external carotid artery 3

A
  • branches off supplying to facial artery- 4th branch

very flexible

branches into smaller arteries to supply cheeks, chin, ocular area, forehead, lips and teeth

22
Q

function of facial veins 1

A

return blood to external jugular from same location of arteries

23
Q

facial vessels importance 1

A

knowing vessel locations can help avoid bruising and occlusion during dermal filler

24
Q

Lymphatic/immune system2

A

vital factor to circulatory and immune system

act as an aid, protect body from disease by developing resistance to pathogens and destroying disease causing microorganisms

25
Q

parts of lymphatic/immune system 5

A

liver
lymph
lymph nodes
thymus gland
spleen
lymph vessels

26
Q

lymph system 3

A

carries lymph fluid

no pumping mechanism

relies on actions of circulatory system and help of muscles to move fluid

27
Q

lymphatic draining 1

A

manually moving collections of lymphatic fluid to drain

28
Q

liver 6

A

gland in the abdominal cavity

secretes enzyme for digestion,

synthesizes proteins

detoxifies and regulates sugar levels of blood,

decomposition of RBC

produces hormones for body function

29
Q

spleen 1

A

large lymph node that fights infection and detoxifies blood

30
Q

lymph node 1

A

gland like structures found in lymphatic vessels

31
Q

lymph 3

A

liquid composed of changing components in interstitial fluid as fluid circulates

disperses WBC and cell nutrients (sugars, fats,salts)

absorbs toxins and wastes

32
Q

lymphatic system functions 4

A

defence against disease and invading bacteria ad toxins developing resistance

drain interstitial fluid in blood

carry excess fluid, waste, and impurities away from cells

aids in swelling, inflammation, and accumulations in blood vessels

33
Q

interstitial fluid 4

A

solution that bathes and surrounds cells

provides cells with nutrients

method of removing cell waste

has components in blood clotting and wound healing
