Blood Function and Components

Blood distributes gases, nutrients, wastes, ions, chemical messengers, and heat throughout the body.
Blood pressure differences drive blood movement.
Blood is a connective tissue composed of formed elements and plasma.

Formed Elements

Formed elements include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets.
Centrifugation separates blood by density, with plasma on top, followed by the buffy coat (leukocytes and platelets), and erythrocyte layer on the bottom.

Blood Plasma

Plasma is the extracellular component of blood.
Its main component is water.
It contains electrolytes, hormones, dissolved gases, nutrients, wastes, proteins (albumin, globulins, transport proteins), and fibrinogen.

Blood Plasma Proteins

Albumin helps maintain blood osmotic pressure.
Globulins include antibodies and transport proteins.
Fibrinogen is involved in blood clotting.

Formed Elements Details

Erythrocytes (red blood cells) contain hemoglobin, transporting oxygen. Variations include oxyhemoglobin, deoxyhemoglobin, and carbaminohemoglobin.
Leukocytes (white blood cells) are involved in defense against pathogens.
- Granulocytes (e.g., neutrophils, eosinophils, basophils) and
- Agranulocytes (e.g., lymphocytes, monocytes).
Platelets are essential for blood clotting.

Blood Analysis Method

Centrifugation is the primary method for separating blood components for analysis.

Blood Function in the Capillaries

Capillaries are the site of substance exchange, enabling gas, nutrient, and waste transfer.
