Q

Antidiuretic hormone (ADH)
what is it?
what does increased mean?
what does decreased mean?
is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine.

A

ADH is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.

A HIGH ADH level causes the body to produce LESS urine.

LOW ADH cause the kidneys to excrete too much water. Urinating MORE, leading to dehydration and a LOW in blood pressure.

A

(DI) is a rare condition in which the kidneys are unable to retain water. Urine concentations is abnormal, but normal glucose

Q

What is arachidonic acid (AA)

A

Arachidonic acid is a polyunsaturated fatty acid

Q

Granulocytes

what are they?
what are their functions?

A

neutrophils, eosinophils, and basophils

Neutrophils:
They kill and digest bacteria and fungi.
-Most numerous
-First line of defense

Eosinophils:
-They attack and kill parasites and cancer cells, and help with allergic responses.

Basophils
-They secrete chemicals such as histamine, a marker of allergic disease, that help control the body’s immune response.

Q

Functions of monocytes

A

They have a longer lifespan than many white blood cells and help to break down bacteria.

22
Q

Function of Lymphocytes.

A

They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders

23
Q

What are the thyroid hormones

A

The thyroid gland is an endocrine gland in your neck. It makes two hormones that are secreted into the blood: thyroxine (T4) and triiodothyronine (T3).

24
Q

How does t4 convert to t3?

name of t 4?
name of t3?

A

T4 is converted into T3, the active form of thyroid hormone, by two enzymes called deiodinases.

t4- thyroxine
t3- triiodothyronine

25
Q

Objective versus subjective

A

Objective– facts

Subjective–opinions or biases

26
Q

A

Pathology is that field of science and medicine concerned with the study of diseases, specifically their initial causes (etiologies)

Biochemical
Clinical
Dietary

28
Q

Define Myalgia, Neuralgia, Arthralgia

A

Myalgia: pain in a muscle or group of muscles.

Neuralgia: pain along the course of a nerve, especially in the head or face.

Arthralgia: pain in a joint

29
Q

What are prostoglandins

A

The prostaglandins are a group of lipids made at sites of tissue damage or infection that are involved in dealing with injury and illness.

30
Q

4 classical sign of inflammation
what doe they means?

A

Calor: heat

dolor: pain

rubor: redness

tumor: swelling

Q

What are the inflammatory mediators?

A

heparin, histamine, prostaglandins

32
Q

What are inflammatory triggers?

A

allergenic response, oxidative stress, toxins

33
Q

COX 1 and COX 2 fucntions

A

COX enzymes are known to be involved in prostaglandin synthesis

COX-1: generates prostaglandins that are involved in the protection of gastrointestinal mucosa

COX-2 generates prostaglandins that mediate inflammation and pain in sites throughout the body

34
Q

How many trimesters?
Weeks?

A

First trimester – conception to 12 weeks.

A

The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave

37
Q

Left versus Right side of Heart
Functions?

A

The left side : heart collects oxygen-rich blood from the lungs and pumps it to the body.

38
Q

Systole versus Diastole

45
Q

Primary form of folate in blood?

A

5-methyltetrahydrofolate

46
Q

Turns genes ON and OFF, expression is different. Code is not

47
Q

What period of fetal development is most vulnerable to injury from toxins?

A

First trimester.

48
Q

Sources of Inflammatory triggers

A

allergenic response, oxidative stress, toxins, pathogens)

49
Q

Innate Immunity

A

Innate - non specific - inherited from parents

50
Q

Adaptive Immunity

A

Adaptive - specific- acquired not inherited

51
Q

Identify what cellular/tissue components are involved in 1st, 2nd, 3rd line of defense

A

1st line - physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, ‘friendly’ bacteria and white blood cells called neutrophils

2nd -nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues.

3rd is specific, Lymphocytes B and T cells, specific to the invader. Then the cell remembers the antigen
