According to the Frank-Starling Law of the heart, as contraction strength increases the stroke volume ________. Group of answer choices decreases shows no change increases

Answers

We can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.

What is the Frank-Starling Law of the heart?

This law indicates the relationship between the volume of the ventricle, specifically the left ventricle, and the strength of its contractions. It follows the logical approach that if there is more volume in the ventricle, the cardiac muscles will have to stretch to allow for the space, which in turn causes a much stronger contraction when these muscles activate.

Therefore, we can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.

Explain the structure and function of the eye as a sensory receptor including the role of;
A) The cornea and lens
B) The iris
C) Rod and cone cells in the retina

NOTE - the letters listed are NOT answers, they are separate points that need clarifying.

Answers

Answer:

A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.

B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.

C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.
