Answer 1

Answer: (D)

antibodies

Answer 2

Some lymphocytes go to the thymus where they develop into blood-circulating T cells that are connected to the lymph nodes and spleen. B cells continue to grow and mature in the bone marrow before entering the lymphatic and circulatory systems. A B cell makes an antibody. T cells, B cells, dendritic cells, and macrophages make up lymph nodes. Most tissues have nodes that drain fluid. Before the lymph is returned to the circulation, antigens are removed from it at the lymph node. Following stimulation by foreign antigens of bacteria, viruses, and tumour cells, the primary role of B lymphocytes is to differentiate into antibody secreting plasma cells.

The lymphatic system is a network of tissues, blood arteries, and organs that facilitates the movement of a colourless, watery fluid into the circulation or bloodstream. The lymph back is the term for this fluid.

The arteries, capillaries, and smaller arterioles in your body each day get about 20 litres of plasma.

After providing nutrients to the body's cells and tissues and collecting their waste, around 17 litres are returned to the circulation via veins. The 3 litres that are left seep through capillaries into the tissues of your body.

The surplus fluid, which is now known as lymph, is absorbed by the lymphatic system and sent to the circulation from tissues all over your body.

Your lymphatic system performs a variety of functions, including

The lymphatic system, as previously established, gathers extra fluid that drains from cells and tissues all throughout your body and sends it to your circulation, where it is then circulated throughout your body.

Proteins and fats are taken up by lymph from the digestive tract and then transferred into the circulation.

The immune system's lymphatic system defends the body from outside interference. It creates, after which it releases white blood cells called lymphocytes (which are immune cells), as well as other immune cells that keep track of and then eliminate foreign invaders including bacteria, viruses, parasites, and fungus.

transports and gets rid of any waste items that might harm the body.
