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
Excretion is the process of removing metabolic wastes or excrements from the body.
Metabolic wastes are substances left over from metabolic processes (such as cellular respiration) which cannot be used by the organism and must therefore be excreted.
These include nitrogen compounds, water, CO2, phosphates, sulphates, etc.
Choice B. Absorption is wrong because absorption is the process of taking in substances into the body or cells.
It is not related to the removal of waste.
Choice C. Metabolism is wrong because metabolism is the sum of all the chemical reactions that occur in an organism.
It is not a process of removing wastes, but rather producing them.
Choice D. Assimilation is wrong because assimilation is the process of incorporating substances into the body or cells.
It is also not related to the removal of waste.
Normal ranges for metabolic wastes vary depending on the type and concentration of the waste, as well as the organism and its environment.
For example, ammonia is a very toxic waste that requires a lot of water for its excretion, while uric acid is a less toxic waste that can be concentrated into a small volume.
Some normal ranges for human metabolic wastes are:
Urea: 2.5 to 6.4 mmol/L in blood serum Uric acid: 3.4 to 7.2 mg/dL in blood serum Creatinine: 0.6 to 1.2 mg/dL in blood serum CO2: 35 to 45 mmHg in arterial blood gas
Correct Answer is B
Explanation
The correct answer is choice B. False.
Arteries are strong, elastic vessels that carry blood away from the heart, except for the coronary arteries that supply blood to the heart muscle.
These are the first arteries to branch off the aorta, which is the main artery that takes blood to the body from the left ventricle.
Choice A is wrong because it contradicts the definition of arteries. Arteries carry blood away from the heart, not to the heart.
