4. THE LYMPHATIC SYSTEM
Ch. 23 Section 3

5. 1. What is the lymphatic system?
The primary function of the system is to collect extracellular fluid and return it to the blood.

6. Vessels of the Lymphatic System
Lymph capillaries carry lymph into larger lymphatic vessels. Lymph drains into the large neck veins of the cardiovascular system.

7. OTHER PARTS OF THE LYMPHATIC SYSTEM
Bone Marrow- the soft tissue inside of bones. Lymphocytes- type of white blood cell that helps to fight pathogens. Lymph Nodes- small bean shaped masses of tissue that remove pathogens and dead cells from the lymph.

9. LYMPH NODES and LYMPHOCYTES
Lymph nodes contain lymphocytes Killer T-Cells- surround and destroy pathogens B-Cells- produce antibodies that attack pathogens White blood cells multiply when infections are in your body, the lymph nodes then fill with WBCs (white blood cells)- this is why your lymph nodes are swollen when you are sick.

10. THYMUS & SPLEEN
The thymus produces T-cells that fight infections, it is located just above the heart. The spleen is the largest organ in the lymphatic system. The spleen produces, monitors, stores, and destroys red blood cells.

11. SPLEEN & TONSILS
Materials in the spleen: Red pulp in the spleen removes unwanted material like defective red blood cells. White pulp helps to fight infections Tonsils- the lymphatic tissue in the nasal cavity, in the back of your mouth, about the size of an olive. Helps defend the body against infection.

15. TODAY’S AGENDA Research for your BODY SYSYEMS BOOK
You and your partner (if you have one) will be gathering information from the textbook. Use Chapters 22-25
PUT ANY INFORMATION THAT YOU GATHER INTO YOUR IAN– THIS WILL BE THE LAST THING WE DO IN YOUR IAN.
PLEASE REMEMBER TO BRING IN A NEW IAN FOR THE 3rd MARKING PERIOD!!!

16. 12/20 AGENDA Checkpoint EXAM (This is like a CRCT, treat it as such!)
2. You need a PEN OR PENCIL to take the EXAM!!!
3. SIT QUIETLY AND WAIT FOR DIRECTIONS!!!

17. DON’T FORGET– HUMAN BODY SYSTEMS TEST TOMORROW 12/21!!!!
AFTER THE CHECKPOINT…
WORK ON YOUR BODY SYSTEMS BOOK– This is due Thursday and will be counted as a Mini-Project Grade!!!
Get your Book from Mrs. Rudick to begin working on your final copy.
Make sure you are working quietly and efficiently or you will be split up!!
DON’T FORGET– HUMAN BODY SYSTEMS TEST TOMORROW 12/21!!!!

18. 12/21 AGENDA!!!! Input Checkpoint Part 2 into I-Respond.
TAKE HUMAN BODY SYSTEMS TEST– Put into
I-Respond as well.
Work on HUMAN BODY BOOKS– Remember these
are DUE TOMORROW at the end of class!!!
PROJECTS NEED TO BE OUT OF MY ROOM TODAY, I HAVE TO HAVE MY ROOM CLEAR SO MY FLOORS CAN BE CLEANED OVER BREAK!!!
