The artery that provides blood to both the liver and spleen is the:
Celiac.
Brachiocephalic.
Renal.
Tibial.
The Correct Answer is A
The celiac artery supplies blood to the liver, spleen, and stomach.
It is one of the three major branches of the abdominal aorta, along with the superior mesenteric artery and the inferior mesenteric artery.
The celiac artery divides into three branches: the left gastric artery, the splenic artery, and the common hepatic artery.
Choice B is wrong because the brachiocephalic artery is a large vessel that arises from the aortic arch and supplies blood to the right side of the head and neck and the right arm.
It has no connection to the liver or spleen.
Choice C is wrong because the renal arteries are paired vessels that arise from the abdominal aorta and supply blood to the kidneys.
They are located below the superior mesenteric artery and above the inferior mesenteric artery.
Choice D is wrong because the tibial arteries are branches of the popliteal artery that supply blood to the lower leg and foot.
They are located in the posterior and anterior compartments of the leg.
The normal range of blood pressure in the celiac artery is about 100-120 mmHg systolic and 60-80 mmHg diastolic.
The normal range of blood flow in the celiac artery is about 200-300 ml/min. The normal diameter of the celiac artery is about 5-7 mm.

Correct Answer is A
Explanation
This is because ventricular systole is the phase of the cardiac cycle when the ventricles contract and pump blood into the arteries.
The blood pressure in the arteries is greatest during this phase because of the forceful ejection of blood.
Choice B.
Atrial diastole is wrong because atrial diastole is the phase of the cardiac cycle when the atria relax and fill with blood from the veins.
The blood pressure in the arteries is lowest during this phase because the ventricles are also relaxed and not pumping blood.
Choice C.
Ventricular diastole is wrong because ventricular diastole is the phase of the cardiac cycle when the ventricles relax and fill with blood from the atria.
The blood pressure in the arteries is low during this phase because the ventricles are not pumping blood.
Choice D.
Atrial systole is wrong because atrial systole is the phase of the cardiac cycle when the atria contract and push blood into the ventricles.
The blood pressure in the arteries is not affected by this phase because the ventricles are still relaxed and not pumping blood.
The normal range for systolic blood pressure is less than 120 mm Hg and for diastolic blood pressure is less than 80 mm Hg.
Correct Answer is D
Explanation
The pulmonary circuit sends oxygen-poor blood to the lungs, where it is oxygenated and returned to the heart.
This is distinguished from the systemic circuit, which sends oxygen-rich blood to the tissues and returns oxygen-poor blood to the heart.
Choice A is wrong because it confuses the pulmonary circuit with the systemic circuit. The pulmonary circuit does not send blood to the tissues but to the lungs.
Choice B is wrong because it only describes part of the pulmonary circuit.
The pulmonary circuit sends oxygen-poor blood to the heart, but only after it has been oxygenated in the lungs.
Choice C is wrong because it confuses the pulmonary circuit with the systemic circuit. The pulmonary circuit does not bring blood from the tissues but from the heart.
