What does pathological fear mean?

User Avatar

Asked by Wiki User

Fear is a basic emotion that causes a person to either run away or become aggressive to defend against an attack. Pathological fear is a fear so severe and debilitating that it significantly interferes normal daily life functions. For instance, some people have a pathological fear of open spaces (commonly called agoraphobia) that can be so severe that they cannot leave their houses to check the mail box - the open space in the lawn is too much for them to handle.

What is the name of a Circulatory system pathology?

User Avatar

Asked by Wiki User

The circulatory system, now generally referred to as the cardiovascular system, can be affected by a variety of diseases that can be broadly classified as infectious, inflammatory, degenerative or cancerous.

An example of an infectious disease of the cardiovascular system would be bacterial endocarditis. This is when a bacteria become attached to one or more valves of the heart and set up a localized infection.

An example of an inflammatory disease of the cardiovascular system would be athlerosclerosis. This is when inflammatory mediators cause the lining of the blood vessels to become "sticky", which allows cholesterol molecules to be deposited in the walls of the vessels. The cholesterol hardens the arteries, making them more likely to rupture or become blocked.

An example of a degenerative disease of the cardiovascular system would be endocardiosis. This is a chronic disease in which the valves of the heart slowly degenerate and become less competent at closing the openings between the heart chambers. Eventually this can lead to congestive heart failure if it becomes bad enough.

An example of a cancerous disease of the cardiovascular system would be hemangiosarcoma. This is a neoplasia that arises from the lining of the blood vessels and branches off from normal vessels to create very fragile pseudo-vessels. Unfortunately, one of the more common symptoms of this cancer is sudden death; thankfully in humans this cancer is relatively rare.

How does kidney failure affect the urinary system?

User Avatar

Asked by Wiki User

The kidneys are the starting point of the urinary system, the organ where urine (waste liquid materials) are filtered out of the blood stream. Dysfunctional or nonfunctional kidneys create abnormal urine, and usually an abnormal amount of abnormal urine. This can range from anuria (no urine) to polyuria (urinating multiple times a day) and from urinating basically straight water (clear, colorless, USG <1.003) to urinating pus, blood, serum, or some combination thereof.

What is blood made out of?

User Avatar

Asked by Wiki User

What makes blood?

You might think that the heart makes blood. It just pumps blood throughout the body. The tissue that makes blood is the Bone Marrow. The Bone Marrow is found in the bone arm. It only makes white and red blood cells. It can be found in your arm above the spongy bone.

_____________________________________________________________________

Bone Marrow when it is healthy

Bone Marrow's color, when it is healthy it looks like pinkish-red. It is filled with many cells that are healthy and productive. When it is seen under a microscope it looks like big dots that are pink and small dots that are red and the gaps between them looks like pinkish-red.

_____________________________________________________________________

Bone Marrow when it is not healthy

When Bone Marrow is not healthy it looks like pink spaces and around it have light green with black dots. It is called "Aplastic" or "empty" marrow. Instead of having it with cells that are healthy and productive, it has fatty filled cells.

Now you might be wondering then what do you do? Read the extras and find out.

_____________________________________________________________________

What is Bone Marrow for

It is to keep you alive by producing blood and sending them to the heart to pump the blood. It is also to replace old red/white cells.

_____________________________________________________________________

Where is Bone Marrow Located

Bone marrow is found in our big bones like the skull, sternum, arm, leg, pelvis. On a bone it is soft on the top or on the bottom inside sometimes in the middle.

_____________________________________________________________________

EXTRAS

The doctors will have two patients instead of one. The reason that they have two patients is because the other patient give you Bone Marrow. Also you two have the same blood type. Ex: if you have blood "A" the means the other person needs blood "A" or blood "O". (Blood "O" is usable for everyone.)(there are four types blood type A,B and AB are the most common and O is less common and there is plasma they use for emergency cases) The doctors place a tube into your Bone Marrow and the other person and he/she will give you some Bone Marrow. Your body automatically rejects/takes the Bone Marrow. You can not see it reject/take the Bone Marrow with a blind eye. You need a telescope to see it reject/take the Bone Marrow.

Now you might be wondering what happens if you can't make it to the doctor's or you don't have a patient that matches? Then read More Extras.

_____________________________________________________________________

More Extras

What happens if you can't make it to the doctor's or you don't have a match? Well, most likely when the ambulance comes they will give you plasma. Like I said in the "EXTRAS" plasma is like blood "O". The only difference between plasma and blood "O" is that you can't survive for a long time with only plasma. So you will need a match.

_____________________________________________________________________

Donating Bone Marrow

When you donate Bone Marrow you need to use your REAL name or you might do it too many times. (about, I think, 2 times a YEAR) You will give them a blood sample to figure out your blood type. You will be called when a person need you and you have the right blood type.

_____________________________________________________________________

Best person to get Bone Marrow

The best person to get Bone Marrow from is you brothers/sisters. NOT your parents because your brother/sister already has the DNA,genes,etc. from your parents just like you. If you don't have any siblings choose your parents. If you have a twin it will be almost a 100% perfect match.

_____________________________________________________________________

what are matches, receiver = A donor= A or O / Receiver = b donor = B or O / receiver = AB donor= A or B or AB or O / receiver = O donor = O

_____________________________________________________________________

FUN FACTS! (FINALLY!)

  • Since Bone Marrow makes blood and is located in the bone it is just like saying Bones make blood!
  • Although light and squashy it is still pretty strong. Just imagine a jello (those thing that are soft and jiggles all the time) and when you try to break it or cut it in half with your bare hands it will be hard!
  • Did you know that the average number of cells in a leg bone is about 440,000,000,000 (440x109).
  • Blood type O can be given to anybody, but it can only be given blood type O
