Which of the following is located in the interstitial spaces within tissues and releases nutrients, immune factors, and oxygen to those tissues?
lymphatics
arterioles
capillaries
veins

The correct answer will be option -capillaries.

Explanation:

The circulatory system of the human body is made up of vessels which carry the lymph and blood in the body. There are three types of vessels present in the body: artery, veins and capillaries.

The artery supplies oxygenated blood from the heart to the body organs which are divided into the minute capillaries in the interstitial spaces of the tissues and provide oxygen and nutrients to the tissues. the carbon dioxide is diffused into these capillaries which are transported to the veins and carries back to the heart.

Thus, option-capillaries is the correct answer.
