please answer fast.... ​

Answer 1

Answer:

The lymphatic system also helps defend the body against germs (viruses, bacteria, and fungi) that can cause illnesses. Those germs are filtered out in the lymph nodes, small clumps of tissue along the network of lymph vessels. Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection

If you are exercising, or performing any kind of activity, your heart will normally beat faster. This allows your heart to pump blood throughout your body, to provide oxygen to the tissues. If you are experiencing fear, anxiety or stress, your heart rate will increase.
