Q

endometriousis

A

an often painful disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond pelvic organs.

Q

Hydatiform

A

a rare mass or growth that forms inside the womb (uterus) at the beginning of a pregnancy

21
Q

ph of blood

A

7.35-7.45

22
Q

eyrthopoesis

A

making new erythrocytes

23
Q

what prevents back flow into the left atrium of the heart

A

bicuspid valve

24
Q

how do our lungs stay in place

A

surface tension

25
Q

Glycolysis is

A

the first step in the breakdown of glucose to extract energy for cellular metabolism.

26
Q

Glycolysis breaks down

A

glucose and forms pyruvate with the production of two molecules of ATP.

27
Q

glycolysis happens

A

in the cytoplasm of a cell

28
Q

where does the kreb cycle occur

A

in the cristae of the mitochondria

29
Q

where is water reabsorbed

A

large intestine

30
Q

why is the krebs cycle important

A

cellular respiration, in which glucose, fatty acids and certain amino acids, the so-called fuel molecules, are oxidized (see Figure). The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP

31
Q

smallest functional unit of the lungs

A

respiratory bronchile

32
Q

ETC happens in

A

the membrane of the mitochondria

33
Q

The electron transport chain is a

A

a system of molecules through which electrons are transferred to generate ATP. It has an important role in both photosynthesis and cellular respiration.

34
Q

what is IgA

A

Immunoglobulin A is a antibody present in the mucosal secretions of most mammals, represents a key first line of defence against invasion by inhaled and ingested pathogens at the vulnerable mucosal surfaces

35
Q

amines are

A

messenger hormones

36
Q

The endocrine system is

A

a collection of glands that secrete chemical messages we call hormones. These signals are passed through the blood to arrive at a target organ, which has cells possessing the appropriate receptor.

37
Q

hormones target

A

the cell

38
Q

thyroid does what

A

creates thyroxine (T4) and triiodothyronine (T3).

39
Q

thyroid is stimulated by

A

TSH from the pituitary gland

40
Q

FSH does what in females

A
  • stimulates ovary to produce steroids
  • ovary will produce estradiol during follicular phase and progesterone during luteal phase
  • surge at midcycle, with LH, triggers ovulation
41
Q

FSH does what in males

A
  • stimulates Sertoli cells to produce androgen-binding protein (ABP), thereby stimulating spermatogenesis
  • FSH also stimulates Sertoli cells to produce inhibin, which provides negative feedback to the anterior pituitary to decrease FSH secretion
42
Q

LH does what in females

A
  • stimulates ovary to produce steoroids
  • surge at midcycle triggers ovulation
  • remember, luteinizing hormone turns the follicle into the corpeus luteum by triggering ovulation
43
Q

LH does what in males

A
  • stimulates Leydig cells to produce testosterone

- testosterone provides negative feedback to anterior pituitary and hypothalamus

44
Q

what is responsible for BP juxtaglumenlar cells

A

kidney

45
Q

helps regulate blood volume

A

atrial natriuretic peptide

46
Q

aldosterone is also

A

sodium

47
Q

brachial cephallic branches into

A

radial and ulnar

48
Q

how is BP calculated

A

systolic pressure over diastolic pressure

49
Q

cardiac output

A

= stroke volume + cardiac output
