How is it used?
The erythrocyte sedimentation rate (ESR) is an easy, inexpensive, nonspecific test that has been used for many years to help detect conditions associated with acute and chronic inflammation, including infections, cancers, and autoimmune diseases. ESR is said to be nonspecific because increased results do not tell the doctor exactly where the inflammation is in the body or what...

Introduction of cell adaptation
Cells are the structural and functional units of tissues and organs. They are capable of adjusting their structure and functions in response to various physiological and pathological conditions. This capability is called cellular adaptation.
Cellular adaptations include:
Atrophy–shrinkage of cells
Hypertrophy–increase in the size of cells which results...

The lens of the eye is normally clear. It acts like the lens on a camera, focusing light as it passes to the back of the eye.
Until a person is around age 45, the shape of the lens is able to change. This allows the lens to focus on an object, whether it is close or far away.
As we age, proteins in the lens begin to break down and the lens becomes cloudy. What the eye sees may appear...

Fetal circulation differs from humans who are already born because of the difference in the circulatory system. Fetuses do not use their lungs, but rely instead on obtaining oxygen and nutrients from the mother through the placenta and umbilical cord.
The fetus’ heart, and not the mother’s heart, builds up...

Anemia is defined as an absolute reduction in the quantity of the oxygen-carrying pigment hemoglobin (Hgb) in the circulating blood. Anemia is further broadly subcategorized into acute and chronic. (See Etiology.)
Anemia usually is grouped into 3 etiologic categories: decreased red blood cell (RBC) production, increased RBC destruction, and blood loss.
Anemia is a manifestation of an...
