Blood and other body fluids have direct contact with the tissues in this type of circulation?
Hawks have a closed circulatory system, meaning that blood flows through a series of vessels and does not come into direct contact with the tissues or organs. This type of system allows for efficient nutrient and oxygen transport to the body's cells.
circulatory system does.
Circulatory system
No, the circulatory system does not produce red and white blood cells. Red blood cells are produced in the bone marrow, while white blood cells are produced in various tissues in the body such as the bone marrow and lymph nodes. The circulatory system is responsible for transporting these cells around the body.
Circulatory system delivers blood (containing oxygen) to cells.

Even if insects have an open circulatory system, which is usually characterized by slow animals with low metabolic rates, their circulatory system does not participate in supplication of oxygen to the tissues and in the gas exchange process. That is handled by the independent tracheal system, the spiracles, which allows direct contact of cells with the air. With this, the oxygen demand can be supplied even with an open circulatory system.source: http://www.biology-questions-and-answers.com/the-circulatory-system.html

most of the cells are in contact with a watery environment
circulatory system does.
The circulatory system pumps the blood which carries the nutrients that the cells needs. The circulatory system gets the nutrients from the digestive system.
Humans have a closed circulatory system with a heart that pumps blood through a network of vessels, while worms have an open circulatory system where blood is pumped through a simple system of vessels and sinuses by the contraction of the body wall. In humans, blood is confined to vessels, while in worms, blood comes into direct contact with tissues. Humans have specialized blood cells like red blood cells, white blood cells, and platelets, while worms may have fewer types of blood cells.
The Circulatory system is a busy system because it can never stop. Your circulatory system is what pumps your blood and gives your cells food water and oxygen and takes waste away from your cells. If your circulatory system ever stopped then you would die.

The circulatory system.
The most obvious answer would be the Circulatory system; however, the Lymph system also transports material throughout the body, it could be compared to the sewer system in a city. If this is for homework though, the right answer would most assuredly be Circulatory system.
