The layer of the walls of arteries and veins that is smooth to prevent abnormal clotting is the:
middle layer, made of smooth muscle
lining, made of smooth muscle
lining, made of simple squamous epithelium
outer layer, made of simple squamous epithelium
The layer of the walls of arteries that helps maintain diastolic blood pressure is made of:
fibrous connective tissue and elastic connective tissue
smooth muscle and fibrous connective tissue
smooth muscle and elastic connective tissue
fibrous connective tissue and simple squamous epithelium
Backflow of blood within veins is prevented by:
Smooth muscle
Valves
Precapillary sphincters
The middle layer
In capillaries, nutrients are transported from the blood to tissue by the process of:
osmosis
diffusion
active transport
filtration
In capillaries, O2 and CO2 are exchanged between the blood and tissue fluid by the process of:
Osmosis
Filtration
Active Transport
Diffusion
A systematic blood pressure reading always consists of two numbers, which are called:
systemic/systolic
systolic/diastolic
diastolic/systolic
diastolic/systemic
Pulmonary blood pressure is always low and thereby prevents:
osmosis of tissue fluid into pulmonary capillaries
filtration of tissue fluid into the alveoli
filtration of tissue fluid into pulmonary capillaries
osmosis of blood plasma into alveoli
Systemic circulation begins at the:
right atrium
right ventricle
left ventricle
left foot
In hepatic portal circulation, blood from the digestive organs and spleen circulates through the _____ before returning to the ______
brain/liver
liver/heart
liver/brain
heart/liver
Venous return in veins that pass through the thoracic cavity is increased by the:
skeletal muscle pump
pumping of the right ventricle
pumping of the left ventricle
respiratory pump
Venous return in the deep veins in the legs is increased by the:
low pressure in the right atrium
respiratory pump
low pressure in the left atrium
skeletal muscle pump
Following a large loss of blood, as in severe hemorrhage, blood pressure will?
Increase
Decrease
Remain the same
Increase, then decrease
Epinephrine increases blood pressure because it:
causes vasodilation
decreases heart rate and force
increases heart rate and force
increases water reabsorption by the kidneys
The vasomotor center is located in which part of the brain?
medulla
hypothalamus
frontal lobes
cerebellum
ADH increases blood pressure because it:
causes vasodilation
increase heart rate and force
decreases water reabsorption by the kidneys
increases water reabsorption by the kidneys
The nerves that carry impulses to regulate the diameter of arteries and veins are:
sympathetic nerves
parasympathetic nerves
somatic motor nerves
visceral sensory nerves
Connective between arteries or between veins that provide alternate pathways for blood flow are called:
capillary networks
venous sinuses
sinusoids
anastomoses
Large, very permeable, capillaries that permit cells or proteins to enter or leave the blood are called:
sinusoids
venous sinuses
anastomoses
precapillary sphincters
Noepinephrine increase blood pressure because it:
increases blood volume
decreases blood volume
causes vasoconstriction
causes vasodilation
When blood pressure decreases, the kidneys secrete:
renin
more water
erythropoietin
all of these
