Answer:
Which two mechanisms influence the force of cardiac contraction?
Answer: End diastolic volume and sympathetic nervous system stimulation
Explanation:
Blood pressure decreases during diastole, which occurs when the heart muscle relaxes. While, blood pressure increases during systole, which occurs when the ventricles contract, pushing blood out of the right ventricle.
The cardiovascular system connects a pump to blood vessels.
Cardiac contraction is the end result of action potentials and it can be defined as a unique ability of cardiac muscle to generate a force that is independent of any load or stretch applied.
End-diastolic volume is the amount of blood in the ventricles just before systole. A person’s end-diastolic volume tends to decrease with age.
End-systolic volume is used in the hospital to determine a measurement known as stroke volume, which is the amount of blood pumped from the left ventricle with each heartbeat.
Sympathetic stimulation causes the release of the neurotransmitter norepinephrine and it increases heart rate and myocardial contractility.
The sympathetic nervous system has a wide variety of cardiovascular effects, among which are, increased cardiac contractility, peripheral vasoconstriction.
Sympathetic nervous system stimulation causes vasoconstriction of most blood vessels.
Yes jaguars eat pythons. But pythons can also eat Jaguars!
Answer:
Hi there!
Your answer is:
Minerals
Explanation:
Minerals help your body grow, develop, and stay healthy. The body uses minerals to perform many different functions — from building strong bones to transmitting nerve impulses. Some minerals are even used to make hormones or maintain a normal heartbeat.

<span>Babies
should be provided with an environment that is suited for sensory exploration.
As babies begin their stages of development they begin to learn things through different
sensory systems. This is the reason why they hold things up and down or play
with objects that are given to them. Babies are generally sponges that absorb
available stimuli in their environment. In able to develop the different
sensory systems parents should give their children the opportunity to explore
the area by touch, sight, smell, taste, and hearing. </span></span></span>
