Q

hypothalamus location

A

brain

21
Q

parathyroid location

A

neck, makes calcium

22
Q

thymus location,

A

in the chest between the lungs

23
Q

Hormones are

A

secreted in very small quantities

24
Q

Hormones have a specific chemical

A

structure and shape that chemically fit onto receptors so they do not trigger the wrong receptors

25
Q

The endocrine system is coordinated

A

coordinated by the pituitary gland which responds to hypothalamus

26
Q

Hypothalamus…

A

constantly checks the internal environment, if the conditions change the hypothothalamus respodns (temperature, metabolism, water content).

27
Q

How does body respond to high and low temperature (veins)

A

dilating vessels (cold air) to increase heat loss and contract (hot air) to decrease heat loss

28
Q

When low temperature (skin)

A

goosebumps are created and hairs stand up on end

29
Q

homeostasis

A

The process of maintaining constant internal environment

30
Q

feedback system

A

a response within a system that influences the continued activity or productivity of that system

31
Q

Duiretic

A

causing increased passing of urine

32
Q

Low water content level

A

Hypothalamus detects little water in blood, message is sent to pituitary gland to start production or increase production of ADH

33
Q

High water content level

A

Detects High levels, stop ADH production, low levels of a ADH going to kidneys, little water absorbed back into the blood, large uncontentrated urine

34
Q

Ectotherm

A

body temperature changes with the temperature of the environment. cannot maintain body temperature

35
Q

Endotherm

A

Internally generated heat to maintain body temperature

36
Q

Negative feedback

A

Variable triggers a counteractive response to maintain homeostasis

37
Q

Positive feedback

A

Variable triggers a response that reinforces the change detected

38
Q

Hypothalamus acts on the

A

pituitary gland which acts on the thyroid gland

39
Q

Thyroxine triggers increased metabolism which

A

generates more heat and warms the body

40
Q

Endoctine system does not have immediate

A

immediate control over body temperature

41
Q

Body temperature is both controlled by the

A

nervous and endocrine systems

42
Q

Hypothalamus when cold sends out

A

nerve impulses around vital organs to begin small contraction and shaking in these muscles.

43
Q

Shivering effect

A

increases activity of muscle cells, producing heat and raising body temperature

44
Q

If temperature is too low (blood flow)

A

the blood flow is reduced further and you can lose feeling in them.

45
Q

Glucose decrease

A

pancreas releases glucagon which triggers the liver to break down glycogen and release glucose

46
Q

Glucose too high

A

pancreas releases insulin making ebody cells take up glucose and liver store as glycogen

47
Q

What two major systems are used to achieve homeostasis

A

Nervous and endocrine
