2017年7月26日 · Our blood contains antibodies and white blood cells which fight viruses, bacteria, and other invaders. Without these vital cells, we would quickly succumb to infections and die. Our white blood cells even fight cancers that originate within our own bodies.

2024年4月29日 · Dive into the life-giving essence of blood anatomy and physiology. Nursing students, here’s your roadmap to understanding the vital river that courses through us, carrying both life and messages. Functions of the Blood. Blood is unique; it is the only fluid tissue in the body. 1. Carrier of gases, nutrients, and waste products.

The cellular elements—referred to as the formed elements—include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets. The extracellular matrix, called plasma , makes blood unique among connective tissues because it is fluid.

2025年3月27日 · Blood, fluid that transports oxygen and nutrients to cells and carries away carbon dioxide and other waste products. Blood contains specialized cells that serve particular functions. These cells are suspended in a liquid matrix known as plasma. Learn more about the components and function of blood.

Blood has four parts: Red blood cells, white blood cells, platelets and plasma. Each part has specific and important tasks, from carrying oxygen to carrying out waste products. Your blood also acts like a kind of health barometer.

2023年10月30日 · Blood is the most important transport medium in the human body. It transports gases (oxygen, carbon dioxide, nitrogen etc.) as well as nutrients (metabolism) and end products of cell metabolism. Hence the blood has the task of assuring the exchange of substances.

Blood is viscous and somewhat sticky to the touch. It has a viscosity approximately five times greater than water. Viscosity is a measure of a fluid’s thickness or resistance to flow, and is influenced by the presence of the plasma proteins and formed elements within the blood. The viscosity of blood has a dramatic impact on blood pressure ...

Blood is composed of 55% plasma and 45% “formed elements,” including red blood cells, white blood cells, and platelets. Because of these living cells suspended in the plasma, blood is considered a fluid connective tissue (not a fluid).

Blood serves as the highway system throughout the body. It transports formed elements and dissolved substances. For instance, blood transports oxygen from the lungs and carbon dioxide to the lungs for gas exchange. Blood absorbs nutrients from the gastrointestinal tract and moves waste from the tissues.
