Blood is a bodily fluid that carries metabolic waste products away from cells in humans and other animals. Blood cells floating in blood plasma make up this organ in animals. Plasma is primarily water (92 percent by volume) and contains proteins, carbohydrates, mineral ions, hormones, carbon dioxide (plasma is the primary medium for excretory product movement), and blood cells themselves. Albumin is the most abundant protein in plasma and is responsible for maintaining blood's colloidal osmotic pressure. Red blood cells, white blood cells, and platelets make up the majority of blood cells. Red blood cells make up the majority of cells in vertebrate blood.
Blood carries oxygen from the lungs to the body's cells, where it is required for metabolism. The blood transports the carbon dioxide created during metabolism back to the lungs, where it is exhaled (breathed out). Blood also nourishes cells, distributes hormones, and eliminates waste products, which are ultimately eliminated by organs such as the liver, kidneys, and intestine.
Blood platelets and other solid blood components, as well as other chemicals dissolved in blood plasma, provide protection. When a blood vessel is injured, the blood portions adhere together (clot) relatively quickly, ensuring that a scrape, for example, does not bleed. Large amounts of fluid are not lost as a result of this. The immune system is also aided by white blood cells and specific chemical messengers.
Blood is slightly basic by nature, having a pH range of 7.35 to 7.45. The pH of blood is often kept close to 7.40 by the body.
Hence, option d is correct that is production of hormones and the remaining options a, b and c are incorrect.
