brachiocephalic

Name the arterial structure in the neck region that contains baroreceptors. (Module 19.18B)

carotid sinus

Arteries of the pulmonary circuit:

carry deoxygenated blood to the lungs

The blood vessel that supplies blood to the liver, stomach, and spleen is the

celiac trunk.

The ________ vein is a superficial vein that ascends along the radial side of the forearm.

cephalic

The internal carotids and the basilar artery are interconnected by an anastomosis called the

cerebral arterial circle.

Chemoreceptor reflexes respond to

changes in carbon dioxide, oxygen, or pH in the blood

What effect does an increase in the respiratory rate have on CO2 levels? (Module 19.11C)

decreases CO2 levels

The ________ divides the aorta into the thoracic aorta and the abdominal aorta.

diaphragm

Identify the hormones responsible for short-term regulation of decreasing blood pressure and blood volume. (Module 19.10A)

epinephrine and norepinephrine

Which vessel immediately gives rise to the femoral artery?

external iliac

Identify the veins that combine to form the brachiocephalic vein. (Module 19.18C)

external jugular, internal jugular, vertebral, and subclavian veins

The external iliac artery becomes the ________ artery as it enters the lower limbs.

femoral

The two common iliac veins form the

inferior vena cava

Which of the following is NOT an artery?

inferior vena cava

Which vessel collects most of the venous blood inferior to the diaphragm? (Module 19.20A)

inferior vena cava

An important artery that supplies blood to the brain is the ________ artery.

internal carotid

Which of the following arteries enter the pelvic cavity to supply the organs of the pelvis?

internal iliac artery

Blood from the brain returns to the heart through the ________ vein.

internal jugular

Major branches of the right subclavian artery include the ________ arteries.

internal thoracic and vertebral

Pulmonary veins carry blood to the

left atrium

A blockage of which branch of the aortic arch would interfere with blood flow to the left arm? (Module 19.17B)

left subclavian artery

Pulmonary arteries carry blood to the

lungs

The vein in the arm commonly sampled for blood by venipuncture is the

median cubital vein.

An artery delivering blood to the kidney would have ________ blood in it and would be part of the ________ circuit.

oxygenated: systemic

Blood pressure increases with all of the following except increased

parasympathetic innervation.

At the posterior knee, the femoral artery becomes the ________ artery.

popliteal

Which of the following break(s) the rule that arteries carry oxygenated blood away from the heart?

pulmonary arteries

Which of the following is a deep vein of the forearm?

radial

Name the two arteries formed by the division of the brachiocephalic trunk. (Module 19.17A)

right common carotid artery and right subclavian artery

The blood vessel that directly carries blood to the arm and shoulder is the

subclavian artery.

The cephalic vein merges with the axillary vein to become the

subclavian vein.

The fusion of the brachiocephalic veins forms the

superior vena cava

Name the two large veins that collect blood from the systemic circuit. (Module 19.16B)

superior vena cava and inferior vena cava

The vessel that receives blood from the head, neck, chest, shoulders, and arms is the

superior vena cava.

Branches off the aortic arch include all of the following except

the right subclavian artery

The ________ vein is a deep vein that ascends along the medial side of the forearm.

ulnar

The brachial artery branches to form the radial and ________ arteries.

ulnar

When will the blood pressure be greater?

when the peripheral vessels constrict

Arrange the following vessels in the order in which blood would pass through them 1. pulmonary venules 2. pulmonary trunk 3. pulmonary veins 4. alveolar capillaries 5. pulmonary arterioles 6. pulmonary arteries

2, 6, 5, 4, 1, 3

Which is a characteristic of the major patterns of blood vessel organization?

A single vessel may have several names as it crosses specific anatomical boundaries.

The superior vena cava collect blood from the

Head, chest, and upper limbs

Name the immediate and long-term problems related to hemorrhage. (Module 19.13B)

The immediate problem related to hemorrhage is maintaining adequate blood pressure and peripheral blood flow. The long-term problems related to hemorrhage is to restore normal blood volume.

Compare the oxygen content in the two circulatory circuits. (Module 19.15A)

The pulmonary circuit carries deoxygenated blood from the right ventricle to the lungs and returns oxygenated blood to the left atrium. The systemic circuit carries oxygenated blood to the organs and tissues of the body and returns deoxygenated blood to the right atrium.
