An individual is running to catch their ride share vehicle when they trip and fall with their hands outstretched. The individual looks up and notices an abrasion from the fall on the palms of their hands but there is no blood. What is the reason for the lack of bleeding? A.The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 5 layers on the palm to reach the vascularized (having blood vessels) basement membrane. B.The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 3 layers on the palm of the hand to reach the vascularized (having blood vessels) basement membrane. C.The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 4 layers on the palm to reach the vascularized (having blood vessels) basement membrane. D.The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 6 layers on the palm to reach the vascularized (having blood vessels) basement membrane.

An individual is running to catch their ride share vehicle when they trip and fall with their hands outstretched. The individual looks up and notices an abrasion from the fall on the palms of their hands but there is no blood. What is the reason for the lack of bleeding?

	A.	The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 5 layers on the palm to reach the vascularized (having blood vessels) basement membrane.
	B.	The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 3 layers on the palm of the hand to reach the vascularized (having blood vessels) basement membrane.
	C.	The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 4 layers on the palm to reach the vascularized (having blood vessels) basement membrane.
	D.	The epithelium is avascular (without blood vessels), so the abrasion must not have penetrated all 6 layers on the palm to reach the vascularized (having blood vessels) basement membrane.
