Answer:
The answers are circulatory system and immune system.
Explanation:
In order to know more about the answer, it is best to learn what a lymphatic system is.
Lymphatic System- This is also known as "lymphoid system." It functions as a part of the body's circulatory and immune system. It consists of<em> lymphatic vessels, lymphatic organs and the lymph.</em>
Lymphatic Vessels- These are thin-walled vessels that carry the lymphatic capillaries. The lymphatic organs include the <em>tonsils, adenoid, spleen and thymus. </em>
<u>The Function of Lymphatic Vessel</u>
- It functions to transport the "lymph," a clear, colorless fluid which contains the white blood cells (these are also called leukocytes).This transportation function explains the lymphatic system being involved with the circulatory system in the body.
Circulatory System- This is the system in the body is responsible for blood flow, oxygen, nutrients and hormones. It also involves removing unwanted things, such as waste products in the body.
<u>The Function of the Spleen</u>
The spleen is one of the lymphatic organs that has an important role. Once it detects an invader in the body's blood such as virus or bacteria, it starts producing white blood cells. These are also known as<em> "leukocytes." </em>
The white blood cells help the body fight infection and other foreign invaders. This clearly explains the lymphatic system being involved with the immune system in the body.
