Blood
Blood is a vital fluid that circulates throughout the body, delivering oxygen and nutrients to
cells and removing waste products. It is made up of several different components, including
red blood cells, white blood cells, platelets, and plasma. The following are some notes on
blood in English.
Composition
Blood is composed of several different components, each of which has a specific function.
Red blood cells, also called erythrocytes, are the most abundant cells in the blood. They
contain a protein called hemoglobin, which binds to oxygen and carries it to the body's tissues.
Red blood cells are produced in the bone marrow and have a lifespan of about 120 days.
White blood cells, also called leukocytes, are cells that help to fight infection and disease.
There are several different types of white blood cells, each of which has a specific function.
They are produced in the bone marrow and lymphatic tissues.
Platelets, also called thrombocytes, are small cells that help to form blood clots. They are
produced in the bone marrow and circulate in the blood.
Plasma is the liquid component of blood. It is composed of water, proteins, electrolytes, and
other substances. Plasma helps to transport nutrients, hormones, and waste products
throughout the body.
Functions
Blood has several important functions in the body, including:
Transportation: Blood carries oxygen and nutrients to cells and removes waste products such
as carbon dioxide.
Regulation: Blood helps to regulate body temperature, pH balance, and fluid balance.
Protection: White blood cells in the blood help to fight infection and disease, while platelets
help to form blood clots to prevent excessive bleeding.
