Answer:

Ammonia:a colourless gas with a characteristic pungent smell, which dissolves in water to give a strongly alkaline solution.

Artery:any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.

Blood:Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma.

capillary:Capillaries are tiny blood vessels connecting arteries to veins. These blood vessels carry oxygen and nutrients to individual cells THROUGHOUT the body.

circulary system:The system that moves blood throughout the body. The circulatory system is composed of the heart, arteries, capillaries, and veins. This remarkable system transports oxygenated blood from the lungs and heart throughout the body via the arteries.

Dialysis:dialysis is the process of separating molecules in solution by the difference in their rates of diffusion through a semipermeable membrane, such as dialysis tubing. ... Dialysis is a common laboratory technique that operates on the same principle as medical dialysis.

Excretion:Excretion is a process by which metabolic waste is ELIMINATED from an organism. In vertebrates this is primarily carried out by the lungs, KIDNEYS and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. 

Excretery system:The excretory system is the system of an organism's body that performs the FUNCTION of excretion, the bodily process of discharging wastes. The Excretory system is responsible for the ELIMINATION of wastes produced by homeostasis
