- a Blood viscosity, and blood vessel length.
- b Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
- c Exchange of gases, nutrients, wastes, hormones etc.
- d Specialized, flattened veins with extremely thin walls (e.g., coronary sinus of the heart dural sinuses of the brain).

5 Multiple choice questions
- In all tissues except for cartilage, epithelia, cornea and lens of eye.
- In the Aorta.
- Vessels of the vessels - larger veseels contain this. Nourish the external tissues of the blood vessel wall.
- Blood flow caused by the pumping action of the heart, pressure results when flow is opposed by resistance.
- High blood pressure, sustained elevated arterial pressure of 140/90 or higher. May be transient adaptations during fever, physical exertion, and emotional upset. Often persistent in obese people.
5 True/False questions
Angiogenesis → Kidney release of renin generates angiotensis II, which causes vasoconstriction. Increase BP.
Tunica Interna (Innermost) → Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
What is Blood Flow inversely proportional with? → Peripheral Resistance (R). - If R increases, blood flow decreases.
factors that aid in venous return → Respiratory pump, muscular pump and vasconstriction of veins under sympathetic control.
Vital Signs → Pulse and blood pressure, along with respiratory rate and body temperature.
