New cards
2

-involved w sleep,wake cycles, & circadian rythms

New cards
4

New cards
7

testes gland

-responsible for making sperm and are also involved in

New cards
8

-producing a hormone called testosterone.

10

(adrenaline)

20

New cards
22

-neurological impulses from pressure and irritation of uterus causes oxytocin release

New cards
23

-oxytocin causes contractins which causes more pressure and irritation -> more oxytocin -> more contractions

New cards
24

3 tropic hormones

Thyroid stimulating hormone (TSH): Stimulates thyroid gland to produce thyroid hormone

New cards
25

New cards
26

Gonadotrophic hormones (FSH & LH): stimulates the gonads to produce estrogen and testosterone

New cards
27

2 class of hormone

  1. Peptide hormone (water soluble): they need membrane proteins to enter cell membrane as they are polar. (cant cross CM)

New cards
28
  1. Steroid hormones (fat-soluble): hormones that are able to enter directly. Reception of this single hormone causesteh cell to produce a product by way of the cellular machinery for protein synthesis

New cards
29

Growth Hormones (GH)

stimulates bone and muscle growth, inceases protein synthesis and fat metabolism

New cards
30

Progesterone (Menstrual cycle)

New cards
31

insulin

-released after eating

New cards
32

-stimulates uptake of glucose by cells

New cards
33

-especially in muscle, liver, and adipose cells

New cards
34

-decreases blood glucose

New cards
35

Cortisol

principal glucocorticoid hormone

New cards
36

ACTIONS:

New cards
37

-promotes breakdown of muscle protein to amino acids

New cards
38

-promotes metabolism of fatty acids, spares glucose

New cards
39

-overall: promotes a rise in blood glucose and beneficial under stress

New cards
40

-Is anti-inflammatory

New cards
41

-can suppress the immune system

New cards
42

Thyroxine

-Also called thryoid hormone,

New cards
43
  • produced and secreted by follicle cells in the thyroid gland.

New cards
44

-it targets all cells in the body and increases overall body metabolism.

New cards
45

Parathyroid hormone

-causes increase in blood calcium and decrease in blood phosphate

New cards
46

-increase osteoclast activity and the reabsorption of Ca+ by the kidneys

New cards
47

-is anatagonistic

New cards
48

negative feedback

when blood calcium levels increase, PTH is shut off (negative feedback + Ca+ = -PTH | -Ca+ = +PTH

New cards
49

Estrogen

-stimulates growth of uterus and vagina

New cards
50

-egg maturation

New cards
51

New cards
53

-Iodine deficiency causes simple goiter.

New cards
54

Testosterone

-Male sex hormone

New cards
55

-regulates male functions

New cards
56

-lack off insulin (pancreas does not produce

New cards
57

-May also be an autoimmune condition

New cards
58

-developes usually during childhood

New cards
59

-as cells break down fats for energy, ketones build up in blood

New cards
60

New cards
82

Rh factor

-The presence of the protein, or lack of it, is reffered to as the Rh (for rhesus factor)

New cards
83

-If your blood does contain the protein your blood is said to be Rh+. If your blood does not contain the protein your blood is said to be Rh-

New cards
84

systolic pressure

When chambers are contracting

New cards
85

When chambers are relaxing

New cards
86

Fibrin

thrombin converts fibrinogen into fibrin which builds a network to form a solid clot.

New cards
87

Anemia

caused by low levels of iron and low levels of RBS

New cards
88

Tromboplastin

Injured tissue released thromboplastin

New cards
89

Thromboplastin stimulates teh production of more prothronmbin activater. this process requires Ca+

New cards
90

circulation of blood in the vessels of the heart muscle (myocardinum)

New cards
91

ECG waves (P)

Atrial contraction begins

New cards
92

Space b/w P + Q (ECG waves)

impulse delay at AV node, ventricles fill

New cards
93

Q (ECG waves)

Ventricular excitation in heart apex. Bicuspid and tricuspid valves close (LUB)

New cards
94

R/S (ECG waves)

Ventricular excitation complete

New cards
95

T (ECG waves)

ventricular relaxation. semilunar valves close (DUB)

New cards
96

QRS

shows electrical activity just before ventricular contraction (large spike)

New cards
97

Inhalation

-external rib muscle and diaphram contract

New cards
98

-expands the rib cage upward and outward, and the floor of chest cavity down.

New cards
99

-the volume of thoracic cavity increased, and the air is contained in a larger space

New cards
100

-When molecules of gas are further apart, they exert less outward pressure
