Q

3 Tunics of Arteries + Their Functions

A
  1. Tunica Intima–(Inner most layer) Consists of Endothelium. Prevents the adhesion of blood cells to the wall of the vessel and prevents clotting
  2. Tunica Media–(middle layer) Contains Smooth Muscle + Elastic Fibers
    Function–The muscle cells contract + relax which allows the vessels to stretch + recoil
  3. Tunica Adventitia–(outer serosal layer)

17
Q
  1. The additional amount of sodium bicarbonate that the body produces to maintain normal arterial pH when the carbon dioxide level increases as a result of hypoventilation
  2. It is maintained by the kidneys, controls bicarbonate ions in urine
A

Alkaline Reserve

18
Q

What artery is within the cortex + medulla of the kidney

A

ARCUATE

19
Q

Functions of Atrial Natriuretic Peptide (ANP)

A
  1. A polypeptide hormone involved in homeostatic control of body water, sodium + adiposity
  2. Released by atrial myocytes (muscle cells in Atrial of heart) in response to high blood pressure
20
Q

Define Arteries and Characteristics

A

Thick, Smooth Walls

  1. Body Composition
  2. Age
  3. Weight
  4. Genger
  5. Body Surface Area (Greater Surface Area-Higher BMR)
  6. Endocrine Glands
  7. More Muscle-Higher Rate
22
Q

A

It leads to:
Anemia
Pernicious Anemia
Neurological Symptoms

23
Q
  1. Cells within the testis that supply nutrients to developing spermatozoa
  2. Also called Sertoli Cells or Nurse Cells
  3. Large cells in the Seminiferous Tubules
  4. Main Function-Nourish developing sperm cells through stages of spermatogenesis
A

Sustentacular Cells

24
Q

Blood flow through Veins controlled how

A

Veins have one way VALVES prevent back flow of blood

25
Q

Volume of a given mass of an ideal gas is proportional to its temperature as long as its pressure remains constant

A

Charlie’s Law

26
Q

Structure of Pancreas

Function-A large gland that secretes hormones

A

Structure

Located below stomach
Develops as 2 separate parts which are fused together
Located near 1st part of small intestine (duodenum)
Broken into several subsections
Head- is near duodenum
Body-Largest part–Located in center of gland below stomach
Tail–furthest from duodenum

27
Q

Structure of Spleen

(Function-Filters blood/ Removes damaged red blood cells_

A

Structure

Organ goes unnoticed by average person
Not critical for survival
1/2 the size of human fist
Locate below rib cage
Purple in color
Shaped like a small catchers mitt
Contains a lot of blood vessels
28
Q

Structure of Stomach

Function-Environment for breaking down material or food that you eat (chemically)

A

Structure

Bag-like structure
Between esophagus + duodenum
On LEFT SIDE of Abdomen
Superior part lays against-Diaphragm
Cavity Composed of :
Fundus 
Body
Antrum
Inside composed of Layers
Innermost to Outer:
1.  Mucosa
2.  Submucosa
3.  Muscularis Externa
4.  Serosa
29
Q

Functions of Vagina

A
  1. Childbirth
  2. Sexual Intercourse
  3. Discharges
  4. Passageway for menstrual blood
30
Q

Force pushing Water + Solutes out of blood and across a filtration membrane

A

Glomerular Hydrostatic Pressure

31
Q

Breakdown of food using CHEMICALS such as enzymes

A

Chemical Digestion

32
Q

Function of Gastric Inhibitor Peptide

A
  1. Enhances Insulin production in response to a high concentration of blood sugar
  2. Also, inhibits absorption of water + electrolytes in small intestine
  3. Numbers increase in people with: Duodenal Ulcers, Inflammation of Pancreas, Diabetes from Obesity
33
Q

Function of ADH

Antidiuretic Hormone

A
  1. Primary Function–Decrease amount of urine excreted by kidneys
  2. Increase water absorbed by kidneys
  3. Plays role in regulating the balance of fluids in the body
34
Q

Function of Blood-Testis Barrier

A

To PREVENT ACTIVATION of

Immune System of male AGAINST the developing sperm

35
Q

Changes In Female when Fertilization Takes Place

A
  1. Production HCG–pregnancy hormone
  2. Secrete high levels of Progesterone
  3. Development of Placenta
  4. Implantation Bleeding
  5. Missed Period
  6. Increase in Body Temperature

  10. Fatigue
  11. Headaches
  12. Bloating, Cramping, Backache
  13. Increase in Urination
  14. Changes in Cervical Mucous
36
Q

Delivery of Placenta

A

After delivery uterus continues to contract + placent detaches from the uterine wall (not painful)
You push + deliver the placenta
Normally happens after the birth
Looks like a piece of liver
Then you have a gush of blood and small clots that follow
May take a few minutes or up to hour
Called 3rd Stage Labor
If does not come out may have to be delivered manually

37
Q

Effectiveness of Absorption in Small Intestine

A

90% of absorption occurs

Good for absorption because it has large inner surface area

38
Q

Stages of Labor

A

1st STAGE-When you start having contractions + ends when cervix if fully dialeted
This Stage is divided into 2 phases:
Early Labor–Cervix gradually effaces (thins out) + dilates (opens)
Active Labor–Cervix dilates more rapidly , contractions stronger + closer together
Last part of active labor called-Transition
First Stage–LASTS THE LONGEST

2nd STAGE–Begins when fully dilated + ends with Birth of Baby
“PUSHING STAGE”
MOST PAINFUL + INTENSE

3rd STAGE–Begins after birth
Ends with Delivery of Placenta

39
Q

Action of Complement Proteins

A

Produced by Liver Cells, in tissue, and by macrphages
They become active when the 1st protein in the pathway is turned on, then following complement proteins are called into action with each protein turning on the next one in line
When the 1st of compliment substances is triggered it usually by an antibody–it sets in motion a ripple effect
They cause the cells to burst + signal phagocytes that a cell needs to be removed

40
Q

Flow of Lymph Fluid

Drainage System

A

An extensive Drainage System that returns water + proteins from various tissues back to the blood

Wherever there are blood vessels there are lymph vessels

Entire Lymphatic System flows toward the blood stream

If there was no way for excess fluids to return to blood our body tissues would become swollen

Lymphatic System also helps defend against invasion by disease causing agents
