What is the largest immune organ?
The spleen is the largest internal organ of the immune system, and as such, it contains a large number of immune system cells. Indeed, about 25 percent of the blood that comes from the heart flows through the spleen on every beat. As blood circulates through the spleen, it is filtered to detect pathogens.

- Fluid balance.
- Protection (immunity)
- Nutrient absorption.
What are the functions of the lymphatic system?
The lymphatic system is our body’s ‘sewerage system’. It maintains fluid levels in our body tissues by removing all fluids that leak out of our blood vessels. The lymphatic system is important for the optimal functioning of our general and specific immune responses.
What are the 3 main functions of the lymphatic system?
The lymphatic system has three major functions, which are discussed here:
- Tissue drainage;
- Fat transport;
- Immune responses.
What are the immune related organs where are they located quizlet?
They are located in the head and neck region (cervical) lymph nodes, tonsillar lymph nodes, sub-mandibular lymph nodes, and sub-mental lymph nodes, the chest (mediastinal lymph nodes), the armpits (axillary lymph nodes), along the collarbone(supraclavicular lymph nodes, the arms, the groin (inguinal) lymph nodes) and …
What is one part of the immune system that helps protect the body from diseases quizlet?
White blood cells, also called leukocytes (LOO-kuh-sytes), play an important role in the immune system. Some types of white blood cells, called phagocytes (FAH-guh-sytes), chew up invading organisms. Others, called lymphocytes (LIM-fuh-sytes), help the body remember the invaders and destroy them.
Which is one part of the immune system that helps protect the body from diseases?
White blood cells: Serving as an army against harmful bacteria and viruses, white blood cells search for, attack and destroy germs to keep you healthy. White blood cells are a key part of your immune system.
What is innate and adaptive immunity?
The immune response is broken down into innate immunity, which an organism is born with, and adaptive immunity, which an organism acquires following disease exposure.
How many types of immune system are there?
This protection is called immunity. Humans have three types of immunity — innate, adaptive, and passive: Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection.
What’s the difference between innate and adaptive immune systems?
Innate immunity is something already present in the body. Adaptive immunity is created in response to exposure to a foreign substance.
What is the Peyer’s patch?
Peyer’s patches are groupings of lymphoid follicles in the mucus membrane that lines your small intestine. Lymphoid follicles are small organs in your lymphatic system that are similar to lymph nodes. … Peyer’s patches play an important role in immune surveillance of materials within your digestive system.
What is the most important part of the immune system?
The primary parts of the immune system include the bone marrow and thymus. The bone marrow is extremely important to the immune system because all the body’s blood cells (including T and B lymphocytes) originate in the bone marrow. B lymphocytes remain in the marrow to mature, while T lymphocytes travel to the thymus.
What does thymus gland do?
The thymus gland is in the chest, between the lungs and behind the breastbone (sternum). It is just in front of, and above, the heart. The thymus makes white blood cells called T lymphocytes (also called T cells). These are an important part of the body’s immune system, which helps us to fight infection.
What are the main functions of the lymphatic system quizlet?
What are the functions of the Lymphatic System? To transport fluids back to blood and act as the bodies defense and resistance to disease.
What are the major functions of lymph quizlet?
the lymphatic system has 3 primary functions:
- drains excess interstitial fluid: -drains from tissue spaces and return it to the blood.
- transports dietary lipids: -lymphatic vessels transport lipids and lipid-soluble vitamins absorbed by the gastrointestinal tract.
- Carries out immune responses:
What are 3 functions of the lymphatic system quizlet?
List the three functions of the lymphatic system.
- Carry fluid leaked out from bloodstream back to the blood.
- Filter out and phagocytize foreign agents.
- Produce and “activate” lymphocytes (B cells and T cells)

What are the structures and functions of the lymphatic system?
The lymphatic system is a subsystem of the circulatory system in the vertebrate body that consists of a complex network of vessels, tissues, and organs. It helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream.
