Mitral valve
Tricuspid valve
Pulmonary valve
Aortic valve
Using the diagram, explain the pathway of blood from the body to the lungs, naming the relevant chambers and vessels.
Blood enters the right atrium via the superior and inferior vena cava, moves to the right ventricle through the tricuspid valve, and is pumped to the lungs via the pulmonary artery.
Blood enters the left atrium via the pulmonary veins, moves to the left ventricle through the mitral valve, and is pumped to the body via the aorta.
Blood enters the right ventricle via the pulmonary veins, moves to the right atrium through the mitral valve, and is pumped to the lungs via the aorta.
Blood enters the left ventricle via the superior vena cava, moves to the left atrium through the tricuspid valve, and is pumped to the body via the pulmonary artery.
Strategically analyze why the left ventricle has a thicker wall compared to the right ventricle, based on its function in the circulatory system.
The left ventricle pumps blood to the entire body, requiring more force.
The left ventricle only pumps blood to the lungs, requiring less force.

It increases potassium excretion, which directly raises blood pressure.
It increases sodium and water reabsorption, raising blood pressure and blood volume.
It stimulates baroreceptors to decrease heart rate.
Which enzyme is responsible for converting angiotensin I to angiotensin II in the R-A-A system?
Renin
Aldosterone
Angiotensin-converting enzyme (ACE)
Adrenaline
What is the primary effect of aldosterone in the Renin-Angiotensin-Aldosterone system?
Decreases blood pressure
Increases sodium reabsorption
Causes vasodilation
Stimulates thirst
Explain how decreased sodium delivery to the kidney can ultimately lead to increased blood pressure through the R-A-A system.
Decreased sodium delivery stimulates renin release, which activates the R-A-A system, leading to vasoconstriction and increased sodium reabsorption, both of which increase blood pressure.
Decreased sodium delivery inhibits renin release, causing blood pressure to drop.
Decreased sodium delivery directly increases aldosterone production without involving renin.
Decreased sodium delivery causes the liver to stop producing angiotensinogen, lowering blood pressure.
Strategically, why might blocking ACE be an effective treatment for hypertension?
It prevents the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone-mediated sodium retention, thereby lowering blood pressure.
It increases renin production, which lowers blood pressure.
It stimulates aldosterone release, which decreases blood pressure.
It causes the liver to produce more angiotensinogen, lowering blood pressure.
Which of the following best explains why more pressure is needed to keep a blood vessel open as its radius decreases in size?
The vessel wall becomes thinner and more elastic.
The vessel wall hypertrophies and becomes thicker, increasing wall tension.
Blood flow decreases, reducing the need for pressure.
The vessel radius increases, lowering wall tension.

Both saturated and unsaturated fats are only found in processed foods.
Unsaturated fats are only found in dairy products.
Explain why cholesterol is considered both beneficial and potentially harmful in the human body, using evidence from its functions and sources.
Cholesterol is only beneficial because it is an essential component of cell membranes.

Which of the following statements best explains the primary function of HDL (high density lipoproteins) in the body?
HDL carries cholesterol back to the liver for removal from the body.
HDL transports triglycerides to tissues for storage.
HDL deposits cholesterol in the walls of blood vessels.
HDL is synthesized in the liver and broken down into LDL.
Why is it important to keep LDL (low density lipoprotein) levels low in the blood?
High LDL can build up in blood vessel walls, leading to plaque and vessel narrowing.
Low LDL increases the risk of fat storage in tissues.
High LDL helps flush cholesterol from the body.
Low LDL causes the liver to produce more triglycerides.
Compare the main function of VLDL (very low density lipoprotein) with that of LDL. How do their roles in fat and cholesterol transport differ?
VLDL mainly carries triglycerides to tissues, while LDL mainly carries cholesterol to tissues.
VLDL and LDL both carry only cholesterol to tissues.
VLDL mainly carries cholesterol to tissues, while LDL mainly carries triglycerides.
VLDL and LDL both remove cholesterol from the body.
A patient has an HDL level of 35 mg/dL and an LDL level of 120 mg/dL. Based on the recommended goals, what should be the primary concern for this patient?
The HDL is below the recommended goal, and the LDL is above the recommended goal.
Both HDL and LDL are within recommended goals.
The HDL is above the recommended goal, but LDL is below the recommended goal.
Only the LDL is above the recommended goal; HDL is not important.
Explain why triglycerides are considered important in the context of lipoproteins and fat storage.
Triglycerides are large lipid molecules stored as fat tissue and are mainly transported by VLDL.
Triglycerides are proteins that help remove cholesterol from the body.
Triglycerides are only found in HDL and are not stored in the body.
Triglycerides are carbohydrates that provide energy for the liver.
