GENERAL HISTOLOGY

Detailed explanation-1: -The body tissue that is composed primarily of fluid and transports nutrients and respiratory gases throughout the body is blood. Blood is technically categorized as a type of connective tissue due to the presence of a fluid matrix (plasma) and cells suspended within the matrix (red blood cells and white blood cells).

Detailed explanation-2: -Blood is the chief transport system of the body. The primary function of blood is to deliver oxygen and nutrients and remove wastes from the body cells. The specific function of blood also includes defense, distribution of heat, and maintenance of homeostasis.

Detailed explanation-3: -Blood vessels are like networks of roads where deliveries and waste removal take place. Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed. The heart is constantly pumping blood so it is always moving around the body.

Detailed explanation-4: -Red blood cells are vital in the transport of respiratory gases.
