Describe the functions of the mammalian blood.

Here are the functions of mammalian blood:

• Transport of gases: Blood transports oxygen from the lungs to the body tissues and carbon dioxide from the tissues back to the lungs.
• Transport of nutrients: It carries digested nutrients (like glucose, amino acids, vitamins) from the digestive system to all body cells.
• Transport of waste products: Blood transports metabolic waste products (such as urea and uric acid) from the cells to the excretory organs (kidneys, liver) for removal.
• Transport of hormones: It carries hormones from endocrine glands to their target organs.
• Regulation of body temperature: Blood helps to regulate body temperature by distributing heat throughout the body.
• Protection against disease: White blood cells and antibodies in the blood provide immunity against pathogens.
• Blood clotting: Platelets and clotting factors in the blood prevent excessive blood loss through clotting.
