Albumins, Globulins, Fibrinogen and clotting factors

Three types of plasma proteins

Fibrinogen

It is a clotting protein dissolved in plasma.

clotting factors

These chemicals are needed for the clot to form.

Serum

It is a plasma with the fibrinogen and clotting factors removed

Ions, Nutrients, Waste products, Gases, Regulatory substances

The concentration of these solutes are important for homeostasis (Other solutes 2%)

ions

In solution they are electrolytes

Nutrients

They are necessary chemicals for normal body function.

amino acids, fatty acids, and vitamins

These and other nutrients are usually absorbed into the blood through

the digestive system

Waste products

They are by-products of chemical reactions that occur in the cells. They are secreted

into the blood for removal

Gases

This enter or leave the body through the lungs, may be required by cells for chemical

reactions to occur

Gases

This may also be produced as a waste product of cellular reactions.

Regulatory substances

They are chemicals used for communication (e.g endocrine hormones)
