Q

white blood cells

A

leukocytes - less abundant than red - involved in host immune defense

17
Q

platelets

A

found in plasma - pieces of cells that are important in blood clotting

18
Q

lymph capillaries

A

found throughout the cardiovascular system - lost fluid diffuses through these into lymphatic system

19
Q

lymph nodes

A

pockets in lymphatic system where the lymph is filtered

20
Q

arteries

A

transport blood away from heart - muscular - relatively high pressure

21
Q

veins

A

transport blood to heart - contain valves to prevent back flow

22
Q

capillaries

A

tiny blood vessels that connect arteries and veins - materials enter and leave the blood
