Kidneys and nephrons are part of the excretory system and blood of the circulatory. Together they are part of the excretory and the circulatory system.
The excretory system is the organ system that includes kidneys and play important role in the elimination and removal of waste and toxic substances from the body.
The excretory system works together with the circulatory to eliminate the waste and gases from the body as they are transported through the blood flow.
The blood is the component of the circulatory system that removes and carries the urea, uric acid, water, and other wastes filtered from the kidney.
Therefore, they are the example of the option J. excretory and circulatory system working together.

Answer:
J. Excretory and circulatory
Explanation:
The role of excretory system is to remove all the waste from our body, both fluid and solid. For example urine, it is a product of our kidneys that help our bodies balance salts and fluids in our bodies.

Blood vessels are constructed of smooth muscle, which is capable of constricting, and slowing down. The correct option is a.
Blood vessels are the thin muscular tubes present in the whole body. There are two types of blood vessels. They are arteries and veins. Both have different functions.
The blood vessels carry the blood and regulate it into the entire body. The artery carries oxygenated blood to the body, and veins carry deoxygenated blood to the heart from the body.
Blood vessels are muscular and they are flexible. They can constrict and expand according to the blood flow. They also control the pressure of the blood. The walls of the arteries and veins are thin and at the same time strong to control the pressure of the blood.
Thus, the correct option is a. slow down.
