Question 2 options:

	1) Increase the peripheral resistance
	2) decrease the peripheral resistance
	3) have no effect on peripheral resistance

Question 3 (1 point)

An example of an elastic artery would be:

Question 3 options:

	1) Aorta
	2) Radial artery
	3) Femoral artery
	4) Capillaries in the nailbed

Question 4 (1 point)

Blood is considered an atypical type of connective tissue because:

Question 4 options:

	1) It connects all the systems to one another
	2) It has all the elements of connective tissue but the fibers only show up during clotting
	3) It has cells and ground substance but no fibers
	4) The cells are atypical

Question 5 (1 point)

Histologically you will NOT see all three tunics (intima, media and adventitia) in a capillary:

Question 5 options:

	1) True
	2) False

Answer 1

1. All WBCs are nucleated.

• Monocytes and lympocytes doesn't have granules.
• Neutrophils, monocytes have the highest phagocytic activity.
• RBCs are the most abundant formed elements in blood.

2. Doping by injection of more RBCs into circulation will increase peripheral resistance, similar to what would happen in a patient with polycythemia.

3. Large arteries like aorta are elastic artery.

4. All typical connective tissues has fibres. Blood is an atypical connective tissue because fibres would show up only during clotting.

5. It's a true statement because capillaries only have a single layer of endothelial cells.
