term to describe the process of red blood cell formation in the bone marrow
erythropoietin
hormone produced ny the kidneys that controls erythropoiesis. People with kidney disease are often aneamic because they fail to produce the hormone
fibrinogen
a protein produced by the liver that circulates in the plasma as a plasma protein. When fibrinogen encounters activated platelets it attaches and is converted into fibrin as part of the clotting process.
hematocrit
a commonly mesured blood value. The blood is spun in a centrifuge and the ratio of packed RBC’s to the total voluma is reported as the hematocrit. The abrivation of hematocrit is Hct. . The value is normally reported at a percentage is as Hct = 48%. Normal values: males (38% - 51%), females (36% - 47%) (hemato = blood, crit = to separate).
Hemophilia
An x-linked genetic condition, seen primarily in males, which prevents normal blood clotting.
Hemostasis
this term refers to the body’s ability to stop blood flow from a broken or cut blood vessel.
Normocytic
A description of the blood taht has the normal amount of erythrocytes
Platelets
These are small cell fragments that have the ability to cluster in areas of vessel injuries and create a physical barrier to blood flow trhough the injured vessel
polycythemia
a condition in which too many RBC’s are proudced and the RBS count and hematiocrit becomes much higher than normal. The condition makes the blood very viscous and puts extra strain on the heart because of the extra resistance to blood flow caused by the increased viscosity.
Reticulocytes
Immature red blood cells that still have their nucleus. Normally reticulocytes extrude their nucleus and become erythrocytes oustide the circulation and then the erythrocyte enters the circulation. When reticulocytes are seen in the circulation it is a sign of rapid RBC production
Septicemia
blood infection caused by a pathogenic bacterium
Aneurysm
If an area of weakened artery begins to enlarge, bulge or distend the bulging or distended area ir called and aneurysm. If a medium sized artery aneurysm ruptures the patient will usually bleed to death before surgical intervention is possible. Aneurysms are often detected when they produced secondary symptoms caused by pressure they put on nearby structures.
Angina pectoris
an ischemic condition of the heart which can pruduce chest pain of exertion
Arteriosclerosis
This condition develops when arterial walls become thickened and less elastic. The loss of elasticity can often be seen in the pulse pressure.
Atherosclerosis
A type of arteriosclerosis in which there are degenerative changes in the lining of the blood vessel. The changes often take the forms of plaques. These elevated plaques present danger because that can trigger thrombus formation.
Embolus
A blood clot that has broken free of a vessel wall and is circulating with the blood. These clots often form in the deep veins of the legs where blood flow is slow (sluggish). When they break free and eneter the circulation they can pass though the right atrium, the right ventricle and enter the arterial side of the pulmonary circulation.
Mitral valve prolapse
a condition in which the mitral valve fails to close properly
pericarditis
the heart rest in a fluid filled sac within the mediastinum. The sac is called the pericardium. When the sac and its fluid contents become inflamed the condition is called pericarditis
valvular stenosis
narrowing of the heart valve. Stenosis often lead to high piched whistling type murmur.
binge
brief excessive consumption of food
cholecystitis
inflammation of the gallbladder
cholelithiasis
presence of gasllstones in the gallbladder or bile ducts
chyme
food that has been swallowed and has mixed with water and digestive enzymes and is passing though the small intestines. As the chyme exits the small intestines and is dehydrated by the large intestines it becomes feces.
chirrosis
a liver condition (disease) characterized by an increase in the amount of connective tissue.
colitis
inflammation of the colon
colostomy
an opening from the colon though the abdominal wall. The opening allows the contents of the colon to exit and by-pass a distal diseased or injured region
diverticulosis
a condition of sac-like (pockets) herniation of mucosa of the colon
enteritis
inflammation of the small intestines
gestroenteritis
inflammation of the stomach and small intestines
gestrooesophageal reflux disease (GERD)
A condition in which a weak or damaged lower esophageal sphincter allows the acidic contents of the stomach to reflux into the lower part of the esophagus which causes inflammation and damage to the mucosal lining
gingiva
gums or mucosa of the mouth on the mandible and maxilla
hemorrhoids
an itching, painful mass of dialated veins either just inside the anal sphincter or protruding outside the anal sphincter. Hemorrhoids are common cause frank bleeding during defecation. The condition is associated with excessive straining during defecation.
Laxative
a medicine or agnet used to relieve constipation, also called purgative
mumps
a viral infection of the parotid salvary gland. The secom M in the MMR vaccine.
peptic ulcer
erosion (ulcer) of the mucosa of the esophagus, stomach or duodenum caused by stomach acid
periodontal disease
disease of the priodontal ligament which holds each tooth in the alveoli of the mandible and maxilla. The result is loosing of the teeth in their sockets.
Acne
inflammation of the subaceous glands caused by an accumulation of secretions. The condition is oftern linked to Propionibacterium acnes and in severe cases can be treated with antibiotics.
Athlete’s foot (Tinea pedis)
A fungal skin infection, usually of the feet, which causes peeling and cracking of the skin between the toes.
Chicken pox
a ciral childhood disease that is spread, primarily via the respiratory system. The condition menifests itself as red ichy papules which appear 2 to 4 dyas after infection and pesist about 14 days. A vaccine is avalible.
Cold sores (fever blisters)
a viral condition that causes leasion around the mouth and lips and on the face. leasions heal in 1 to 3 weeks without any treatment. However, this is a reservoir disease and the leasions can return latter in life.
decubitis ulcer (bed or pressure sores)
Lesions which develop where pressure has reduced circulation to the tissues of the skin. Patients who are bedridden can develop these lesions in areas where the skin is compressed between bony prominences and the mattress.

Rubeola (red measles)
A higly contagious viral infection affecting mainly children. Even though Rubeola is called measels, it is much more serious disease than rubella. The fever, rash and respiratory symptoms are much more pronounced and bacterial respiratory complications are frequently seen.
Shingles
A skin condition that results from a reactivation of the latent virus which had preciously caused chicken pox during the patient’s youth. Chicken pox is caused by a member of the herpes family of viruses.

A mild conditions that is usually treated symptomatically. Underlying conditions inculde dehydration, vitamin deficiencies and diabetes. The dry skin is often very itchy.
Botulism
Causes by a neurotoxin of the anaerobic bacteria Clostridium botulinum. The toxin bind to motor neurons supplying the muscle of the respiratory system and the other skeletam muscles of the body and prevents normal impulse transmission from reaching the muscles.
Cerebral palsy
A non-progressive non-contagious impairment of the muscles function stemming from damage to the motor cortex of the brain. Damage can occur during fetal development, during childbirth or during early post-natal development.
