Question

describe the structure of blood​

Answer 1

Answer:

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.

Answer 2

Answer:

Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

The Role of Blood in the Body

Blood, like the human blood illustrated in the body’s systems and homeostasis. Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste. Red blood cells contain hemoglobin, which binds oxygen. These cells deliver oxygen to the cells and remove carbon dioxide.

Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss after injury. Blood also transports the disease-fighting agents white blood cells to sites of infection. These cells—including neutrophils, monocytes, lymphocytes, eosinophils, and basophils—are involved in the immune response.

Red blood cells, or erythrocytes (erythro– = “red”; –cyte = “cell”), are specialized cells that circulate through the body delivering oxygen to cells; they are formed from stem cells in the bone marrow.

White blood cells, also called leukocytes (leuko = white), make up approximately one percent by volume of the cells in blood. The role of white blood cells is very different than that of red blood cells.

Components of Blood

Hemoglobin is responsible for distributing oxygen, and to a lesser extent, carbon dioxide, throughout the circulatory systems of humans, vertebrates, and many invertebrates.
