What direction does blood flow from the arteries

Answers

Answer 1

Answer:

Answer: The things that are listed .

Explanation: The circulatory system is made up of blood vessels that carry blood away from and towards the heart : Arteries carry blood away from the heart and veins carry blood back to the heart .

Answer 2

Answer: Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels.

Select the correct statement about cardiac output. (A) Decreased venous return will result in increased end diastolic volume.(B) Stroke volume increases if end diastolic volume decreases. (C) If a semilunar valve were partially obstructed, the end systolic volume in the affected ventricle would be decreased. (D) A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.

Answers

Answer:

The correct answer is option D.

Explanation:

The cardiac output is the blood amount that heart pumps in a minute. In other words, the amount of blood pump by the left ventricle of the heart in a 1 contraction is termed as the stroke volume. The stroke volume and the heart rate determine the cardiac output. Slow heart rate increases the end-diastolic volume, stroke volume, and force of contraction.

Thus, the correct answer is option d.

The correct statement about the cardiac output is a slow heart rate increases end-diastolic volume, stroke volume, and force of contraction. Therefore option D is correct.

A slower heart rate allows for a longer diastolic filling time, which leads to increased end-diastolic volume.

This increased volume, in turn, enhances the stretch of the cardiac muscle fibers, known as the Frank-Starling mechanism, leading to a stronger force of contraction and ultimately an increased stroke volume.

Consequently, when the stroke volume increases, and heart rate remains slower, the overall cardiac output can still be maintained or even increased.

Therefore, option D accurately represents the relationship between heart rate, end-diastolic volume, stroke volume, and force of contraction in cardiac output.
