Question

A swelling of tissue or skin caused by an excessive accumulation of fluid in the tissue is called:

a. edema
b. erythema
c. dermatitis
d. keratosis

Answer 1

A swelling of tissue or skin caused by an excessive accumulation of fluid in the tissue is called a. edema.

Step-by-step explanation:

Edema is a medical term used to describe the swelling of tissue or skin due to the abnormal buildup of fluid in the affected area. This condition is characterized by the retention of excess fluids in the interstitial spaces, leading to visible and palpable swelling. Edema can result from various underlying causes, such as injury, inflammation, or an imbalance in the body's fluid regulation.

Edema occurs when there is an increased permeability of blood vessels, allowing fluid to leak into the surrounding tissues. This can manifest as localized swelling or a more generalized condition affecting multiple areas of the body. The excess fluid puts pressure on nearby structures, leading to discomfort and potential complications. It is crucial to identify and address the root cause of edema to formulate an appropriate treatment plan.

Effective management of edema often involves treating the underlying condition, such as resolving inflammation or improving circulation. Medical interventions may include diuretics to reduce fluid retention and lifestyle modifications. Elevating the affected limb, compression therapy, and dietary changes are also common approaches to alleviate symptoms associated with edema.

In conclusion, the term for a swelling of tissue or skin caused by an excessive accumulation of fluid is edema. This condition underscores the importance of understanding and addressing the factors contributing to fluid imbalance in the body.

Answer 2

A swelling of tissue or skin caused by an excessive accumulation of fluid in the tissue is called edema.The correct option is (a).

Step-by-step explanation:

Edema refers to the swelling of tissue or skin caused by an excessive accumulation of fluid in the interstitial spaces. The accumulation of fluid leads to an increase in the volume of the affected area, resulting in noticeable swelling. This condition can occur for various reasons, such as an imbalance in fluid regulation, inflammation, or underlying medical conditions.

Firstly, it's essential to understand that edema is not a specific disease but rather a symptom of an underlying issue. The human body maintains a delicate balance of fluid distribution between blood vessels and tissues. When this equilibrium is disrupted, fluid can leak into the surrounding tissues, causing edema. Factors such as heart failure, kidney disease, and certain medications can contribute to the development of edema.

Secondly, the accumulation of fluid in tissues can be quantified by assessing the net balance between the forces that drive fluid out of the blood vessels (hydrostatic pressure) and those that pull fluid back into the vessels (osmotic pressure). Edema may result from an increase in capillary permeability, a decrease in plasma proteins, or an elevation in hydrostatic pressure. Understanding these mechanisms is crucial for diagnosing and managing the underlying causes of edema effectively.

In conclusion, edema is a clinical manifestation of abnormal fluid dynamics within the body. Recognizing it as a symptom prompts further investigation into the root cause, allowing healthcare professionals to tailor appropriate interventions and treatments.
