The blood plasma contains inorganic ions which are important in regulating cell function and maintaining homeostasis.
The cell's plasma membrane does not simply form a "sack" in which to keep all the cytoplasm and other cellular organelles. The plasma membrane is a very important structure which functions to allow certain substances to enter or leave the cell. It can "pump" other substance into the cell against the concentration gradient or pump other "wastes" etc. out of the cell.
Some of the transport process happens "passively" without the cell needing to expend any energy to make them happen. These processes are called "passive transport processes".

Plasma help to regulate the body's osmotic pressure. It also transfers various compounds needed by the body. Also plays a role in the immune system and blood clotting. Plasma protein makes up 7% of the blood volume.
Plasma is a transport medium in the blood. Apart from red and white blood cells and platelets, it also transports soluble products of digestion (like glucose and amino acids). It takes oxygen and carbon dioxide to and from cells, which too dissolve in the plasma. Hormones are even transported to target organs from endocrine glands.
Plasma is the fluid part of the blood. It is a mixture of water, minerals, nutrients, sugars, proteins and other substances. Plasma also carries waste.
1. Albumin - osmotic balance , ph buffer
2. fibrinogen - clotting and viscosity
3. Immunoglobulin - defence
The main functions of plasma proteins include Maintaining osmotic pressure, Composing the clotting proteins, and to help regulate pH.
membrane permeablity
Plasma proteins are proteins that are present in blood plasma. The normal laboratory value of plasma total protein is around 7 g/dL.
Blood plasma is 95% water. Other components of blood plasma include clotting factors, proteins, and glucose; blood cells are not part of the plasma.
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins
plasma membrane of the cell
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.
plasma proteins determine......
The two main functions of the proteins found in the plasma membrane are transport and inter-cellular communication. There are so many other roles that proteins play in the cell.
Most of the active functions of plasma membranes are carried out by proteins.
The relative amounts of proteins and lipids
Phospholipids and integral proteins.
Diverse proteins embedded in the lipid bilayer or positioned at one of its surfaces carry out most of the membranes functions.
Proteins and lipids
Albumin consist 60 percent of all plasma proteins. Therefore, they are the most abundant proteins.
4 major parts of a plasma membrane * proteins * lipid bilayer * carbohydrates * cholesterol
If there is a decrease in the amount of plasma proteins, then overall health is affected. There are three main plasma proteins-albumins, globulins, and fibrinogen-that contribute to the composition of plasma. Osmotic pressure and the transport of fatty acids, thyroid hormones, some steroid hormones, and other substances will decrease. The amount of antibodies transported by the plasma will also decrease. Finally, the blood will not be able to clot properly because of the decrease of certain proteins in the plasma.
Kidneys do not form plasma proteins. All plasma proteins, or blood proteins, are made in the liver, the one exception to this being gamma globulins.
There are innumerable functions of proteins in the body. Well, the primary functions of proteins include building and repairing of body tissues, regulation of body processes and formation of enzymes and hormones.
