Plasma Composition and Functions Quiz

Study Notes

Intravascular Fluid (Blood Plasma)

Mainly composed of blood plasma, which is the fluid part of blood containing water, electrolytes, proteins, and nutrients.
Intravascular fluid is contained within blood vessels, including arteries, veins, and capillaries.

Interstitial Fluid

The main component of interstitial fluid is the fluid that surrounds cells in tissues, facilitating the exchange of materials between blood and cells.
Interstitial fluid is also known as tissue fluid.

Transcellular Fluid

Found in transcellular spaces such as synovial fluid in joints, cerebrospinal fluid, and pleural fluid.
The main function of transcellular fluid includes providing lubrication, aiding in nutrient transport, and cushioning organs.

Extracellular Fluid

Primarily consists of interstitial fluid and intravascular fluid, crucial for maintaining cellular homeostasis.
Functions of extracellular fluid include delivering nutrients to cells and removing waste products.

Intracellular Fluid (ICF)

Located inside cells, comprising the majority of the body's fluid content.
Plays essential roles in cellular processes and metabolism.

Blood Plasma Components

Main components of dissolved proteins in blood plasma include albumin, globulins, and fibrinogen.
Blood plasma aids in transporting nutrients, hormones, and waste products through the circulatory system.

Functions of Fluids

Functions of transcellular fluid include anti-inflammatory response and acting as a medium for physiological processes.
Blood plasma's key role in maintaining electrolyte balance is through the regulation of ion concentrations, crucial for nerve and muscle function.

Protection and Transport

Blood plasma protects the body by suspending immune cells and transport proteins that neutralize pathogens.
Common substances transported through blood plasma include glucose, amino acids, and carbon dioxide.

Description

Test your knowledge on the composition and functions of plasma, including dissolved proteins such as fibrinogens, globulins, and albumins. Learn about the importance of plasma in transporting excretory products, maintaining electrolyte balance, and protecting the body from infections and blood disorders.
