Verified step by step guidance

1. Begin by identifying the primary function of each system listed in the problem. The digestive system is responsible for breaking down food and absorbing nutrients. The respiratory system is involved in gas exchange, primarily oxygen and carbon dioxide. The lymphatic system is part of the immune system and helps in the removal of waste and toxins.
2. Next, consider the role of the cardiovascular system. It is responsible for circulating blood throughout the body, which includes transporting nutrients, oxygen, and waste products to and from cells.
3. Understand that plasma is a component of blood. It is the liquid portion that carries cells, nutrients, hormones, and waste products.
4. Recognize that the kidneys are organs that filter blood to remove waste products and excess substances, which are then excreted as urine.
5. Conclude that the cardiovascular system is the system responsible for transporting plasma to the kidneys, as it circulates blood throughout the body, including to the kidneys for filtration.
