Certainly, here are the names of the six lymphatic trunks, two collecting ducts, the body regions drained by them, and the points where lymph empties into the bloodstream: **Lymphatic Trunks:** 1. **Lumbar Trunks:** Drain lymph from the lower limbs, lower abdominal wall, and pelvic organs. 2. **Intestinal Trunks:** Collect lymph from the stomach, intestines, pancreas, spleen, and part of the liver. 3. **Bronchomediastinal Trunks:** Drain lymph from the thoracic cavity, including the lungs, heart, and thymus gland. 4. **Subclavian Trunks:** Collect lymph from the upper limbs, shoulders, and part of the thoracic wall. 5. **Jugular Trunks:** Drain lymph from the head and neck. 6. **Lymphatic Trunks of the Upper Limb and Thorax:** Drain lymph from the upper limb and the chest. **Collecting Ducts:** 1. **Right Lymphatic Duct:** Drains lymph from the right upper limb, right side of the head, neck, and upper torso. 2. **Thoracic Duct:** Collects lymph from the rest of the body, including the left upper limb, left side of the head, neck, and entire lower body. **Body Regions Drained by the Lymphatic Trunks and Collecting Ducts:** - **Lumbar Trunks:** Lower limbs, lower abdominal wall, pelvic organs. - **Intestinal Trunks:** Stomach, intestines, pancreas, spleen, part of the liver. - **Bronchomediastinal Trunks:** Thoracic cavity, including lungs, heart, thymus. - **Subclavian Trunks:** Upper limbs, shoulders, part of the thoracic wall. - **Jugular Trunks:** Head and neck. - **Lymphatic Trunks of the Upper Limb and Thorax:** Upper limb and chest. - **Right Lymphatic Duct:** Right upper limb, right side of the head, neck, upper torso. - **Thoracic Duct:** Left upper limb, left side of the head, neck, entire lower body. **Points of Lymph Emptiness into the Bloodstream:** Lymph empties into the bloodstream at two points: 1. **Right Lymphatic Duct:** The right lymphatic duct empties lymph into the right subclavian vein. This occurs at the junction between the right subclavian vein and the right internal jugular vein. 2. **Thoracic Duct:** The thoracic duct empties lymph into the left subclavian vein. This occurs at the junction between the left subclavian vein and the left internal jugular vein. These points of entry allow the lymph, along with its immune cells, proteins, and other components, to rejoin the circulatory system and contribute to maintaining fluid balance and immune function in the body.
