Which of the choices below best describes the systemic circulation of blood?a. The flow of blood into the right atrium and eventually out of the left ventricle.b. The movement of blood from the pulmonary trunk, through capillaries into the pulmonary veins.c. The movement of blood into the coronary arteries, through capillaries into the coronary sinus.d. The movement of blood from the aorta, through arteries and capillaries and then eventually to the vena cavae.
If a patient has cirrhosis of the liver and is unable to produce sufficient albumin and other plasma proteins, then what variable is changed in capillary exchange, and what is the effect?
a. There is no change in the capillary exchange process.
b. Hydrostatic pressure in the blood decreases, and fluid remains in the blood.
c. Colloid osmotic pressure in the capillary increases, and blood volume increases in the blood vessels.
d. Colloid osmotic pressure in the capillary decreases, and fluid remains in the interstitial fluid, potentially causing edema.
