What other body systems does the immune system work with?
The immune system includes the skin; secretions of mucus, tears, sweat, and saliva; and white blood cells. The immune system works closely with other body systems, including the integumentary, circulatory, and lymphatic systems.
What body system deals with infection?
What Is the Immune System? The immune system is the body’s defense against infections. The immune (ih-MYOON) system attacks germs and helps keep us healthy.
How does the immune and nervous system work together?
The immune system and the nervous system maintain extensive communication, including ‘hardwiring’ of sympathetic and parasympathetic nerves to lymphoid organs. Neurotransmitters such as acetylcholine, norepinephrine, vasoactive intestinal peptide, substance P and histamine modulate immune activity.
How does the immune system function?
The immune system is a complex network of cells and proteins that defends the body against infection. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognise and destroy the microbe quickly if it enters the body again.
How does the immune system and the endocrine system work together?
The immune system is highly receptive to endocrine signals due to the expression of hormone receptors on immune cells. The impact of this immune–endocrine cross talk and related immune responses becomes clearly evident when assessing immunity from a sex-specific perspective.
Which system of our body is activated in response to infection and how does it respond?
The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. The main cells of the immune system are lymphocytes known as B cells and T cells.
