What body system does the arterial wall and the fatty deposit belong to

The wall of the arteries belongs to the circulatory system.  The fat deposit belongs to the adipose connective tissue.

Explanation:

The arterial system is the high pressure portion of the circulatory system. Blood pressure ranges from the maximum pressure during cardiac contraction, called systolic pressure, to the minimum pressure, or diastolic pressure, between contractions when the heart rests between cycles. This variation in pressure in the arteries produces a pulse that is observable in any artery, and is an indicator of cardiac activity. The wall of the arteries is thick, formed of elastic muscle tissue.

Adipose tissue is a type of connective tissue with special properties. It has many adipocytes, specialized cells, which have the main function of energy reserve, through a fat deposit, for the body, among others. Fat is deposited in fat cells also called adipocytes.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
