Blood leaves the heart through the arteries, which conducts oxygen to the various tissues and organs.
Sensory nerve endings
Specialized neurons that are stimulated to fire action based on chemical factors. This nerve passes impulses from receptors toward the central nervous system.
A branched cytoplasm surrounding an elliptical, speckled nucleus having one or two nucleoli. They make collagen, glycosaminoglycanes, reticular, and elastic fibers.
A large granular cell commonly found in connective tissues. They release heparin, histamine, and serotonin during inflammation and allergic reactions
White blood cells
A blood cells that lack gemoglobin, colorless and with nucleus. Protects the body's immune system against invading microorganisms.
Adipocytes (fat cells)
A connective tissue that contains adipocytes, fat
