Document Summary
Describe how one might acquire increase in interstitial uid known as edema. Discuss concept of venous return and why it"s important to heart function. Provides accessory route by which uid can be returned from interstitial to blood. Lymph: interstitial uid that enters lymphatic vessel. Eventually empty into venous system near where blood enters ra. One way valves spaced at intervals direct ow of lymph toward venous outlet in chest. Lymph nodes have phagocytes which destroy bacteria ltered from interstitial uid. At the nodes is where the uid is screened for infection. 7200 l blood transported throughout body per day by cv system. About 17 l gets back into system but remaining 3 l of gets absorbed into lymph. As soon as it"s in lymphatic system it is called lymph . Once it leaves capillaries, it is called interstitial uid . Disruption of balance between ltration and absorption. Venous system transports blood back to heart.
