parts of blood and it's function Related: Syllabus for Science, Class...
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including:
- Transporting oxygen and nutrients to the lungs and tissues
- forming blood clots to prevent excess blood loss
- carrying cells and antibodies that fight infection
- bringing waste products to the kidneys and liver, which filter and clean the blood
- regulating body temperature
Red Blood Cells or Erythrocytes - They carry the protein hemoglobin, which transports oxygen from the lungs to the rest of the body.
White Blood Cells or Leukocytes -They are primarily responsible for protecting the body from infection.
Platelets or Thrombocytes - They help the blood clotting process (or coagulation) by gathering at the site of an injury.
Plasma - It is the liquid component of blood and transports blood cells throughout the body along with nutrients, waste products, antibodies, clotting proteins, chemical messengers such as hormones, and proteins that help maintain the body's fluid balance
