Chapter 79 Lymphatic System
Chapter 79 lymphatic system. Fats enter the lacteals and pass through the lymphatic vessels to the venous circulation. The swelling of lymph nodes during an infection and the transport of lymphocytes via the lymphatic vessels are but two examples of the many connections between these critical organ systems. This book will be a comprehensive study of the lymphatic system and its immunological role.
The lymphatic system is an elaborate network of vessels that act harmoniously to pump fluid and cells collectively called lymph from the interstitial space into the blood circulation. This chapter focuses on the lymphatics in the context of the central nervous system CNS. Lacteals are special lymphatic vessels located in the lining of the small intestine.

The lymphatic system is also a network of vessels that run throughout the body Figure 2. Start studying Test Chapter 79 Lymphatic System 15 questions. These veins join to form the superior vena cava the large vein that drains blood from the upper body into the heart.
Rather the lymphatic system is an open system with the fluid moving in one direction from the extremities toward two drainage points into veins just above the heart. Despite comprising only 2 of the bodys mass it is responsible for 25 of the bodys metabolism which leads to the generation of waste products that need efficient and effective clearance. The lymphatic vessels drain into collecting ducts which empty their contents into the two subclavian veins located under the collarbones.
Albeit often neglected the lymphatic system serves multiple functions to the cardiovascular system the most relevant being volume homeostasis. The brain itself is a complex organ. Variations and difficulties in the differentiation between normal and abnormal are especially mentioned.

The primary secondary tertiary etc.
Cardiovascular and lymphatic system assessments. Works with circulatory system to remove waste and excess fluids. The swelling of lymph nodes during an infection and the transport of lymphocytes via the lymphatic vessels are but two examples of the many connections between these critical organ systems. The lymphatic system is comprised of a series of blind ended single cell thick initial lymphatic vessels that drain progressively into successively larger vessels and eventually return interstitial fluid back to the systemic circulation. The lymphatic system is also a network of vessels that run throughout the body Figure 2. The lymphatic system works auxiliary to the venous vasculature by collecting excess interstitial fluid proteins particles and cells that have leaked into tissues returning these into the blood. The spread of a process can be modified by the connections of the collector vessels the single nodes respectively as well as. It will begin with lymphatic capillaries their origin and development.
