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
