Blood Components Quiz

Blood Composition

• Blood is composed of three main cellular elements: red blood cells, white blood cells, and blood platelets
• Red blood cells, also known as erythrocytes, are responsible for carrying oxygen throughout the body
• White blood cells, also known as leukocytes, are part of the immune system and help fight infections
• Blood platelets, also known as thrombocytes, play a crucial role in blood clotting and hemostasis

Extracellular Matrix

• The main component of the extracellular matrix in blood is plasma, which is a liquid substance that makes up about 55% of blood volume
• Plasma is composed of water, salts, sugars, lipids, hormones, and gases, and serves as a medium for the transport of nutrients, waste, and hormones

Waste Removal

• Blood plays a crucial role in waste removal by transporting waste products from the body's tissues to the excretory organs, such as the kidneys and liver, for removal
• Blood picks up waste products, such as urea, creatinine, and bilirubin, from the body's tissues and transports them to the excretory organs, where they are removed from the body

Blood Platelet Function

• When damage to blood vessels occurs, blood platelets aggregate and release chemical signals that attract other platelets and promote blood clotting
• The aggregation of blood platelets forms a platelet plug, which helps to physically seal off the damaged blood vessel and prevent blood loss

Hormone Transportation

• Blood plays a crucial role in the transportation of hormones throughout the body
• Hormones, such as insulin and thyroxine, are produced by endocrine glands and released into the bloodstream, where they are transported to their target cells and tissues
