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
The fibrous pericardium is the loose-fitting sac around the heart that protects it and anchors it to surrounding structures.
Choice B is wrong because the epicardium is the outer layer of the heart wall, also called the visceral pericardium, and it is not a sac.
Choice C is wrong because the endocardium is the inner layer of the heart wall that forms the lining of all heart chambers, and it is not a sac.
Choice D is wrong because the visceral pericardium is another name for the epicardium, and it is not a loose-fitting sac.
Correct Answer is A
Explanation
This is the correct sequence of parts through which blood moves from the vena cava to the lungs.
Choice B is wrong because it reverses the order of the right atrium and right ventricle. Blood flows from the right atrium to the right ventricle, not the other way around.
Choice C is wrong because it switches the positions of the tricuspid valve and the pulmonary valve.
Blood flows from the right atrium through the tricuspid valve to the right ventricle, and then through the pulmonary valve to the pulmonary artery.
Choice D is wrong because it also switches the positions of the tricuspid valve and the pulmonary valve, and reverses the order of the right atrium and right ventricle.
Blood flows from the right atrium through the tricuspid valve to the right ventricle, and then through the pulmonary valve to the pulmonary artery.
The normal range of blood pressure in the vena cava is about 0 to 5 mmHg, while in the pulmonary artery, it is about 15 to 25 mmHg.
The normal range of oxygen saturation in the vena cava is about 60% to 80%, while in the pulmonary vein, it is about 95% to 100%.
