High carbon dioxide levels and low pH in blood of the carotid arteries will stimulate -
ANSWER: chemoreceptors to activate the vasomotor center.
Atherosclerosis involves a - ANSWER: sustained increase in resistance that leads to
increases in arterial pressure to maintain adequate blood flow.
Filtration and reabsorption are processes that involve water (a solvent) but not
solutes - ANSWER: False
Which statement accurately describes total blood flow? - ANSWER: Total blood flow
equals cardiac output and can vary significantly over time with activity levels.
Gas, nutrient, and waste exchange occur between the __________ and the tissues of
the body - ANSWER: capillaries

false
The force per unit area that blood places on the inside wall of a blood vessel -
ANSWER: is called Blood pressure
The cardiac center of the brainstem includes the - ANSWER: cardioacceleratory
center, from which sympathetic pathways extend.
Aldosterone and atrial natriuretic peptide have ________ effects on blood pressure.
- ANSWER: opposite
As a venous pathway moves closer to the heart, the veins - ANSWER: get larger
Hemorrhage with a large loss of blood causes ______ - ANSWER: a lowering of blood
pressure due to change in cardiac output
Blood within the pulmonary veins returns to the ____ - ANSWER: left atrium
Which vessel(s) of the heart receive(s) blood during right ventricular systole? -
ANSWER: pulmonary trunk
Why do asthmatics often carry epinephrine pens with them? - ANSWER: epinephrine
stimulates dilation of bronchioles
The respiratory center is most likely to cause an increase in the breathing rate if the -

The force responsible for normal expiration is supplied by the - ANSWER: elastic
recoil of tissues and surface tension.
