Electrolytes:
* Sodium (Na+): Plays a vital role in regulating fluid balance, nerve impulse transmission, and muscle contraction.
* Potassium (K+): Essential for nerve and muscle function, as well as maintaining a healthy heartbeat.
* Calcium (Ca2+): Involved in blood clotting, muscle contraction, and bone health.
* Magnesium (Mg2+): Important for enzyme activity, nerve function, and muscle relaxation.
* Chloride (Cl-): Helps maintain fluid balance and acid-base balance.
* Bicarbonate (HCO3-): Plays a critical role in buffering blood pH.
Proteins:
* Albumin: The most abundant protein in plasma, it maintains blood pressure, transports hormones, and binds to certain medications.
* Globulins: Include antibodies (immunoglobulins) that fight infection, as well as transport proteins.
* Fibrinogen: A clotting factor that helps stop bleeding.
* Other proteins: Enzymes, hormones, and clotting factors.
Nutrients:
* Glucose: The primary energy source for cells.
* Amino acids: Building blocks for proteins.
* Lipids (fats): Provide energy and insulation.
* Vitamins: Essential for various metabolic processes.
Waste products:
* Urea: A nitrogenous waste product from protein breakdown.
* Creatinine: A waste product from muscle metabolism.
* Bilirubin: A breakdown product of heme, the molecule in red blood cells that carries oxygen.
Gases:
* Oxygen (O2): Transported from the lungs to the tissues.
* Carbon dioxide (CO2): Transported from the tissues to the lungs to be exhaled.
Other components:
* Hormones: Chemical messengers that regulate various bodily functions.
* Drugs: Medications that are being transported throughout the body.
The specific composition of plasma can vary slightly depending on factors such as age, diet, and overall health.
