Acne vulgaris is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules. Acne vulgaris typically affects the areas of skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back.
How does acne affect the integumentary system?
Development and Effects of Acne
Sebaceous glands become clogged with sebum, a naturally occurring skin oil, and dead skin cells. Bacteria becomes trapped in these clogged follicles, producing pus and inflammation as the immune system attempts to destroy the bacteria.
How does acne affect skin function?
Normally as the body sheds skin cells, the keratinocytes rise to the surface of the skin. When someone has acne, the hair, sebum, and keratinocytes stick together inside the pore. This prevents the keratinocytes from shedding and keeps the sebum from reaching the surface of the skin.
What body systems are affected by acne?
Most often, acne affects the skin of the face, back, upper chest, and shoulders.
What affects integumentary system?
The integumentary system is susceptible to a variety of diseases, disorders, and injuries. These range from annoying but relatively benign bacterial or fungal infections that are categorized as disorders, to skin cancer and severe burns, which can be fatal.
How does acne affect the endocrine system?
Excess production of hormones, specifically androgens, GH, IGF-1, insulin, CRH, and glucocorticoids, is associated with increased rates of acne development. Acne may be a feature in many endocrine disorders, including polycystic ovary disease, Cushing syndrome, CAH, androgen-secreting tumors, and acromegaly.
How does acne affect the epithelial tissue?
Initially, the epithelial cells that line the hair follicle become abnormally sticky. These cells clog the follicular orifice with sebum, a substance produced by the sebaceous gland. The resulting lesions are referred to as open and closed comedones or, more commonly, blackheads and whiteheads.
What country has the worst acne?
Results: The overall adjusted prevalence of self-reported acne was 57.8% (95% confidence interval 56.9% to 58.7%). The rates per country ranged from 42.2% in Poland to 73.5% in the Czech and Slovak Republics. The prevalence of acne was highest at age 15-17 years and decreased with age.
Is the integumentary system an organ system?
The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands.

Can acne be systemic?
Acne is also a cardinal component of many systemic diseases or syndromes, such as congenital adrenal hyperplasia, seborrhea-acne-hirsutism-androgenetic alopecia syndrome, polycystic ovarian syndrome, hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, Apert syndrome, synovitis-acne-pustulosis- …
What underlying health conditions cause acne?
For example, hair loss, excess hair growth, irregular menstrual cycles, or rapid weight gain or loss in addition to acne, or rapid onset of acne with no prior history of acne, can all be red flags of an underlying disease, such as polycystic ovarian syndrome, or other endocrine disorders.
What interacts with the integumentary system?
The integumentary system works with all other bodily systems—such as the nervous, cardiovascular, and digestive systems—to accomplish all the jobs it performs in helping to maintain the stability of the internal body.
What does the integumentary system do?
The integumentary system is the largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain. The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails.
How does the integumentary system work with the nervous system?
The integumentary system reduces water loss, contains receptors that respond to touch, regulates body temperature, and protects the inside of the body from damage. Receptors in skin send sensory information to the brain. The autonomic nervous system regulates peripheral blood flow and sweat glands.
