Special lymphatic capillary in small intestine villi that absorbs dietary fats (chylomicrons).

Short-term immunity gained by receiving antibodies from another source (ex: breast milk).

What muscle is most responsible for inhalation?

The diaphragm —it contracts downward to increase thoracic volume

How do vaccines create active immunity?

They expose the body to antigens so memory cells can form.

What is inside a chylomicron?

Reassembled triglycerides, cholesterol, and proteins for transport.

Why does lymph move slowly?

There’s no central pump—movement depends on muscle contractions and valves.

Why do dietary fats enter the lymphatic system first?

Because chylomicrons are too large to fit into blood capillary pores—they fit better through lacteal openings.

What is the main function of the lymphatic system?

To return fluid to the bloodstream, absorb fats, and filter pathogens.

Muscles between the ribs that contract to expand the chest during inhalation.

Main lymphatic vessel that drains most of the body and empties into the left subclavian vein.

Network of vessels that return excess fluid to the bloodstream and help filter pathogens.

Long-term immunity gained by natural exposure or vaccines.

Clear fluid that carries immune cells, waste, and absorbed fats
