What two systems are interacting in this scenario? These two systems work together to pick up and filter nitrogenous waste (urea) from the body. excretory and immune circulatory and excretory circulatory and endocrine integumentary and immune

## Step 1<br />The problem is asking us to identify the two systems that work together to pick up and filter nitrogenous waste (urea) from the body. The options provided are: excretory and immune, circulatory and excretory, circulatory and endocrine, and integumentary and immune.<br /><br />## Step 2<br />The excretory system is responsible for the elimination of wastes produced by the body. This includes the filtration of nitrogenous waste (urea) from the body.<br /><br />## Step 3<br />The circulatory system, on the other hand, is responsible for the transportation of substances throughout the body. This includes the transportation of waste products to the excretory system for elimination.<br /><br />## Step 4<br />Therefore, the two systems that work together to pick up and filter nitrogenous waste (urea) from the body are the circulatory and excretory systems.
