Answer 1

Answer:

(a) Total peripheral resistance: (2) the amount of friction blood encounters during flow through blood vessels.

(b) Blood pressure: (4) the force of the blood against the vessel wall.

(c) Cardiac output: (1) the volume of blood pumped out by one ventricle each minute.

(d) Blood viscosity: (3) the friction red blood cells encounter when moving past each other.

Explanation:

• Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow.  This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance.

• Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows.  This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.

• Cardiac output: Volume of blood that is pumped by the heart per unit of time. The cardiac output depends on the volume of blood pumped by a ventricle by beat.

• Blood viscosity: It is a resistance measurement to flow. The blood viscosity increases as the number of blood cells increase. The more viscose is the blood, the more resistance to movement it is, and the more blood pressure it requires to flow through vessels. Blood viscosity might be dangerous as it might cause uncontrolled coagulation.
