Lymphatic system

Site where resistance to blood flow is greatest

Arterioles

Which statement best describes arteries? A.) all carry oxygenated blood to the heart B.) all carry blood away from the heart C.)only large arteries are lined with endothelium D.) all contain valves to prevent the backflow of blood

B carry blood away from the heart

Which of the following is likely during vigorous exercise?

Capillaries of the active missives will be engorged with blood

shock that results from large-scale loss of blood volume, or after severe vomiting or diarrhea

Circulatory shock known as hypovolemic shock is:

The pulse pressure is: A.)systolic pressure plus diastolic pressure B.)diastolic pressure +1/3 (systolic pressure plus diastolic pressure) C.) systolic pressure divided by the diastolic pressure D.)systolic pressure minus diastolic pressure

D systolic pressure minus diastolic pressure

What does not affect blood pressure?

Emotional state

Site where the velocity of blood flow is the greatest

Large arteries

Site where blood pressure is least

Large veins

Site where blood volume contained is greatest

Large veins

The arteries that are also called distributing arteries are the?

Muscular arteries

What chemical does not control blood pressure?

Nitric acid

Carries oxygen rich blood from the lungs

Pulmonary vein

Supplies the small intestine

Superior mesenteric artery

Very large because resistance is inversely proportional to the fourth power of vessel radius

The influence of blood vessel diameter on pepiheral resistance is:

what tunic of an artery contains endothelium

Tunica interna (Intima)

Vascular due to extreme vasodilation as a result of loss of vasomotor tone

Which of the following is a type of circulatory shock?

continuous capillaries are?

abundant in the skin and skeletal muscles

Site that is the major determinant of peripheral resistance

arterioles

Artery usually palpated to take the blood pressure.

brachial artery

Site where exchanges of food and gases are made

capillaries

Site where the velocity of the blood flow is least

capillaries

Major artery of the thigh

femoral artery

longest vein in the body

great saphenous vein

Site where the blood pressure is greatest

large arteries

Which tunic of an artery is most responsible for maintaining blood pressure and continuous blood circulation?

tunica media
