Study Notes

Edema

Edema is the swelling of body parts, particularly the lower extremities like the feet, ankles, and legs.
It occurs due to the accumulation of excess fluid in the interstitial spaces.
Edema can be caused by various factors, including high blood pressure, diabetes, heart failure, kidney failure, and deep vein thrombosis.

Skin Changes with Age

As we age, testosterone levels decrease, leading to a reduction in axillary and pubic hair.
Skin color changes, often appearing paler due to hormonal fluctuations.
Hair growth patterns can change, resulting in thinner and grayer hair as hair follicles shrink.

Importance of Melanin

Melanin, a pigment found in skin, protects against harmful UV rays from the sun.
Individuals with darker skin pigmentation, such as African Americans and American Indians, have a lower incidence of skin cancer due to this protective melanin.

Skin Functions

The skin serves as a barrier against microorganisms preventing them from entering the body.
It also plays a crucial role in regulating body temperature and preventing water and electrolyte loss.
One of its functions is to absorb and excrete certain substances, including metabolic waste products.
These waste products include minerals, sugars, amino acids, cholesterol, uric acid, and urea.
