Hemostasis is the body’s natural way of stopping bleeding, and it’s a marvel of our physiological design. It’s most effective in dealing with injuries to small blood vessels like arterioles, capillaries, and venules, which are the usual culprits in everyday bleeding episodes. However, it’s ineffective when controlling bleeding from medium or large arteries.

Introduction: Blood, often called the fluid connective tissue, plays a fundamental role in maintaining the body’s equilibrium. Comprising both plasma and blood corpuscles, this remarkable substance constitutes approximately 30-35 per cent of the extracellular fluid in our bodies. An average adult weighing 70 kilograms harbours around 5.5 litters of blood, a testament to its paramount
Maintaining proper levels of water and electrolytes and removing nitrogenous waste are necessary for all animals to survive. Regulating water and electrolytes is known as osmoregulation, and eliminating nitrogenous waste is called excretion. These processes are closely related but have different names. Both of these processes contribute to homeostasis, which is essential for life. In vertebrates, the kidneys are responsible for both osmoregulation and excretion, while invertebrates have specialized organs for these functions.
