The Lymphatic system

inflammatory response

The ________ is a non- specific defense mechanism that occurs when tissues are damaged.

Sinusoids drain

________ into the longitudinal vein that exits the bone.

stomach

The ________ produces hydrochloric acid, saliva and tears contain lysosomes, and the mucous membranes trap foreign particles that are inhaled.

lymphatic vessels

The ________ also play a role in disease resistance by filtering out harmful substances, such as bacteria and viruses, from the lymph.

thymus

The ________ is located in the chest, overlaying the heart.

metabolic rate

It involves increased ________ of damaged cells and increased capillary permeability, leading to the build- up of fluid (edema) and the migration of neutrophils and monocytes to the site of damage to remove pathogens and damaged cells.

immune cells

They help transport lymph (a clear fluid that contains ________, waste products, and excess fluid) back to the bloodstream.

tonsils

The ________ are a group of lymphoid tissues located in the throat.

Lacteals

________ are specialized lymphatic capillaries that pick up digested lipids in the small intestine and transport chyle to the bloodstream through the thoracic duct.

Chyle

________ is lymph mixed with lipids.

T

________ lymphocytes (________ cells) mature in the thymus and stimulate the production of B cells.

spleen

The ________ is located on the left side of the stomach and is the largest lymphoid organ in the body.

physical barrier

The skin serves as a(n) ________ to prevent entry of pathogens into the body.

immune system

It plays an important role in the ________ during childhood by producing antibodies and lymphocytes to fight infection.

Lymphatic capillaries

________ are open- ended tubes that carry lymph back to the heart and away from lymph nodes.

Lymph

________ is a thin, watery fluid that is similar in composition to interstitial fluid.

B

________ lymphocytes (________ cells) develop in the bone marrow and undergo a cloning process to produce copies of themselves, which then turn into plasma cells that produce antibodies.

lymphoid organs

The ________ are a group of tissues that produce and store lymphocytes, which are white blood cells that help protect the body against infection and disease.

lymph nodes

There are two types of defensive cells in the ________: macrophages, which engulf and destroy foreign substances, and lymphocytes, which provide an immune response to antigens.

bacterial growth

The skin's pH is slightly acidic, which helps prevent ________, and sebum is toxic to bacteria.

Lingual tonsils

________: located at the back of the tongue.

Antigen presenting

________ cells, such as macrophages, dendritic cells, and reticular cells found in the thymus, present antigens to T cells and B cells to initiate an immune response.

Reticular cells

________ found in the red bone marrow allow for the formation of white blood cells, and later turn into adipose tissue, forming yellow bone marrow.

specific defense mechanisms

The ________ involve the immune system and the production of antibodies that target specific pathogens.

digestive nutrients

It is formed when plasma diffuses into tissue spaces, and it contains water, ________, salts, hormones, oxygen, carbon dioxide, lymphocytes, and metabolic wastes.

Pharyngeal tonsils

________ (adenoids): located in the upper part of the throat.

thymus

The ________ also produces hormones as adults.

lymphatic vessels

The ________ are a one- way system that carries lymph towards the heart.
