Answer:
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
Explanation:
the question is incomplete, but I annex the options and their explanation
When you compress the heart in this demo, why does the water leave the artery?
A It's like squeezing a sponge
B The arterial valve draws water from the ventricle.
C The atrioventricular valve has parachute-shaped fins to prevent water from escaping from the top.
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
the atrioventricular valve during the contraction process closes at the top, thus avoiding the leakage of the liquid and leaving the artery that opens due to the force exerted by the volume and force of the ventricle.
Answer:
Autonomic nervous system
Explanation:
Autonomic nervous system controls body functions that do not require thought.
<h2>Muscular strength</h2>
Explanation:
Muscles that are elongated while activated (i.e., eccentric muscle action) are stronger and require less energy (per unit of force) than muscles that are shortening (i.e., concentric contraction) or that remain at a constant length (i.e., isometric contraction)
stronger muscle contraction includes:
- Potassium accumulate in the sarcoplasm
- Increase in muscle belly circumference
- Increased stimulus frequency
- Increased requirement
- Lesser proportion of motor neurons to muscle fibers
weaker muscle contraction includes:
- Begin contraction with muscle already 50% contracted
- Circular arrangement of muscle fascicles
- Lower sarcoplasm pH
The correct answer in the given statement above in a way of
completing it is the MMR. The MMR vaccine is a vaccine used for immunization in
means of fighting certain diseases such as rubella, mumps and even measles in
which is being administered by injection.
