Secondary lymph nodes spleen

Lymph nodes are located in clusters throughout your body in theneck, armpits (axilla), chest, abdomen, and groin.There are hundreds of these small, bean-shaped filters, which are connected by a network of vessels and are part of your immune system to help fight infection and disease. 

Lymph nodes filter lymphatic fluid, trapping and destroying waste, bacteria, viruses, and cancer cells with lymphocytes (white blood cells). They are small, bean-shaped organs in the immune system that act as checkpoints along lymph vessels, producing more lymphocytes when fighting an infection, which can cause them to swell

2)Lymph nodes act as filters for the lymphatic system, trapping and destroying harmful substances like bacteria, viruses, and cancer cells from the lymph fluid that circulates through the body

they act as filters

2.The function of lymph nodes is to filter lymph fluid, trap germs, and destroy harmful invaders. They alert and activate immune cells to fight infections, keeping the body safe from disease.

• Plasma: The liquid component that makes up about 55% of blood.

• Red Blood Cells (Erythrocytes): Cells that carry oxygen from the lungs to the body and return carbon dioxide to the lungs.

• White Blood Cells (Leukocytes): Cells that are part of the immune system and help fight infections.

• Platelets (Thrombocytes): Cell fragments that play a crucial role in blood clotting.

plasma(keeps pressure and stops blood from clotting)

the body's coordinated reaction to harmful or foreign substances, like bacteria and viruses, involving physical barriers, non-specific cells, and specific adaptive cells to destroy them. the types of response are rapid, non-specific innate immune response and the slower, highly specific adaptive immune response.

types are innate and adaptive

2. The immune system uses innate cells like phagocytes (macrophages, neutrophils), natural killer (NK) cells, and mast cells
