Why is blood needed by all the parts of a body

Blood is needed by all parts of the body as it is an important part of the transport system of our body. It performs the following important functions: 1)It transports O 2from the lungs to all the body cells. 2) It carries CO 2, a waste product back to the lungs so that it can be exhaled easily. 3)It transmits heat, thus regulating the body temperature. 4)It also fights off diseases and infections.

(ii) Carries carbon-dioxide, waste products back to the lungs so that it can be exhaled easily. (iii) Blood fights against diseases and infections.

Blood has a fluid (liquid) matrix called plasma, in which red blood corpuscles (RBCs), white blood corpuscles (WBCs) and platelets are suspended. The plasma contains proteins, salts and hormones. Blood flows and transports gases, digested food, hormones and waste materials to different parts of the body. Hence it is required by all parts of the body.

Overview of Blood and Blood Components What is blood? Blood is the life-maintaining fluid that circulates through the entire body. What is the function of blood? Blood carries the following to the body tissues: • Nourishment • Electrolytes • Hormones • Vitamins • Antibodies • Heat • Oxygen • Immune cells (cells that fight infection) Blood carries the following away from the body tissues: • Waste matter • Carbon dioxide What are the components of blood? The components of human blood are: • Plasma. The liquid component of the blood in which the following blood cells are suspended: • Red blood cells (erythrocytes). These carry oxygen from the lungs to the rest of the body • White blood cells (leukocytes). These help fight infections and aid in the immune process. Types of white blood cells include: • Lymphocytes • Monocytes • Eosinophils • Basophils • Neutrophils • Platelets (thrombocytes). These help in blood clotting. Where are blood cells made? Blood cells are made in the bone marrow. The bone marrow is the spongy material in the center of the bones that makes all types ofblood cells. There are other organs and systems in our bodies that help regulate blood cells. The lymph nodes, spleen, and liver help regulate the production, destruction, and function of cells. The production and development of new cells in the bone marrow is a process called hematopoiesis. Blood cells formed in the bone marrow start out as stem cells. A stem cell (or hematopoietic stem cell) is the firs...

Blood is needed by all parts of the body as it is an important part of the circulatory system of our body. It performs the following functions: (1) It carries oxygen from the lungs to the cells of the body. (2) It carries carbon dioxide, a waste product back to the lungs so that it can be exhaled. (3) It helps in regulating the body temperature (4) It also fights off infections and diseases. (5) It forms clots and covers the wounds preventing the loss of more blood.

Hint:Blood is a bodily fluid that carries metabolic waste products away from cells while supplying essential nutrients and oxygen to them in humans and other species. In vertebrates, it is composed of blood cells suspended in plasma. Complete Answer: Humans cannot survive in the absence of blood. Without blood, the body's organs would be deprived of oxygen and nutrients, and we would be unable to maintain body temperature, combat pathogens, or remove waste. If we didn't have enough blood, we'd become weak and die. All parts of the body receive oxygen and nutrients from blood, helping them to function properly. Blood transports carbon dioxide and other waste products to the lungs, kidneys, and digestive system, where they are expelled from the body. Blood also helps the body combat diseases and transports hormones. Blood consists of blood cells and plasma. Plasma is a yellowish fluid containing nutrients, proteins, hormones, and waste. Different types of blood cells perform different functions. The heart pumps blood throughout our bodies, carrying oxygen to every cell, with each heartbeat. After supplying oxygen, blood returns to the heart.The blood is then sent to the lungs by the heart to pick up more oxygen. This cycle is repeated indefinitely. Blood vessels in the circulatory system transport blood away from and toward the heart. Blood is carried throughout our bodies by two types of blood vessels: Arteries are vessels that transport oxygenated blood (blood that has rec...
