Think of blood as a gas/ fuel for the car ( your body). If there is no fuel, there's no movement (dead) so when the fuel tank is damaged the car won't function properly.
So if the heart becomes damaged, or weakened it would start making blood clots and damage the organs that need blood to function properly. The circulatory system wouldn't function properly and because other organs depend on the circulatory system it would cause a chain reaction, affecting other body systems. <span />
The correct answer is option (D) store and release neurotransmitters.
The function of synaptic vesicles inside the axon terminals is to store and release the neurotransmitters. A synapse refers to the junction between the two neurons which transmit the nerve impulses by the diffusion of a neurotransmitter. Synaptic vesicles ar important for the transmission or the conduction of the nerve impulses as they store and release the neurotransmitters.
These neurotransmitters are the chemicals that transmit an impulse between two neurons or a neuromuscular junction. A neurotransmitter is released by the synaptic vesicle of one neuron into a region between the two neurons called the synapatic cleft. From here, it reaches the neurtransmitter receptors present on the target neuron, thus conducting the impulse. Examples of neurotransmitters include the epinephrine, histamine, acetylcholine and others.
