Anatomy and Physiology II Lymphatic System-Part 2

Classes of lymphocytes are?

B cells, T cells, Natural killer cells (NK), macrophages, dendrite cells, reticular cells

Expanded, sac-like chamber at the base of the thoracic duct.

Cisterna chyli

Cisterna chyli

It receives lymph from the inferior part of the abdomen, pelvis and lower limbs

Lymphocytes account for 20-40 percent of circulating ______?

Leukocytes

Lymph is drained into the cisterna chyli by?

Lumbar trunks and intestinal trunk

At intervals, lymph flows through and is filtered by ________ and Lymph eventually drains into the _______ ?

Lymph nodes and Lymph trunks

Sequence of flow through the lymphatic system is?

Lymphatic capillaries, Lymphatic vessels, Lymphatic trunks, then lymphatic ducts

one way drainage system composed of a series of capillaries, vessels, cells, tissues and organs, that collect excess fluid and cellular debris from tissues and return them back to the blood

Lymphatic system

Deposits Lymph into one of the two large ducts in the chest region?

Lymphatic trunk

Like one way roads that run parallel to the blood veins

Lymphatic vessels

Difference between lymphatic vessels and Lymphatic capillaries

Lymphatic vessels: vein-like vessels, smaller vessels, bead-like appearance, contain 1-way valves, and contraction by smooth muscle in vessel wall Lymphatic capillaries: more permeable thn blood vessels, epithelial cells overlap and loosely attach to each other, act as 1-way valves, thinner walls, basement membrane is incomplete or absent

Sensitive to specific chemicals (antigens)

Lymphocytes

Empties into the right subclavian vein

Right lymphatic duct

Lymph travel from two large ducts into venous circulation via _______ and ________.

Right lymphatic duct Thoracic duct

What are the 2 lymphatic ducts?

Right lymphatic duct and thoracic duct

What areas of the body are drained by the 2 lymphatic ducts?

The Thoracic duct collects lymph from the left side of the head, left side of the upper body, and lower body, and the Right lymphatic duct collects lymph from the right side of the head and the upper body.

Overlap and form flap-like structures that act as a 1-way valve?

The epithelial cells of lymphatic capillaries

Empties into the junction of the internal jugular and left subclavian vein

Thoracic duct

Where does lymph return to the blood?

Transported through lymph vessels to lymph nodes before emptying ultimately into the right or the left subclavian vein, where it mixes back with blood."

Originate in the blood capillary beds and found in most tissues

lymphatic capillaries
