Anatomy and physiology are difficult to separate because:
Physiological functions depend on anatomical structures.
Our understanding of physiology is changing more than our understanding of anatomy.
Body parts take up space.
Physiological functions in an organism are ongoing.
The Correct Answer is A
This is because anatomy and physiology are closely related branches of biology that study the structure and function of living organisms respectively.
Anatomy describes the shape, size, location, and relationships of body parts, while physiology explains how those parts work together to maintain life.
For example, the anatomy of the heart determines how it pumps blood, and the anatomy of the lungs determines how they exchange gases.
Choice B is wrong because our understanding of both anatomy and physiology is constantly changing as new discoveries are made in the field of biology.
Choice C is wrong because body parts take up space regardless of their physiological functions.
Choice D is wrong because physiological functions are not limited to an organism, but can also occur at the cellular, tissue, organ, and system levels.

Correct Answer is B
Explanation
Cardiac output is calculated by multiplying the stroke volume by the heart rate, not by the systolic blood pressure.
Stroke volume is the amount of blood circulated by the heart with each beat. Heart rate is the number of beats per minute.
Systolic blood pressure is the pressure in the arteries when the heart contracts. Choice A is wrong because it confuses systolic blood pressure with heart rate.
Systolic blood pressure is not directly related to cardiac output, although it can be affected by it.

Correct Answer is C
Explanation
The conversion of fibrinogen to fibrin by thrombin is the final step in the formation of a blood clot.
Fibrin is a protein that forms a net-like structure that traps platelets and other blood cells, making the clot stronger and more durable.
Choice A is wrong because the formation of a prothrombin activator is the first step in the formation of a blood clot.
A prothrombin activator is a complex of enzymes that converts prothrombin to thrombin.
Choice B is wrong because the conversion of prothrombin to thrombin by the prothrombin activator is the second step in the formation of a blood clot.
Thrombin is an enzyme that converts fibrinogen to fibrin.
Choice D is wrong because tissue damage is not a step in the formation of a blood clot, but a trigger for the clotting process.
When blood vessels are injured, they release substances that activate platelets and clotting factors.
