Explanation:

The reason for the fact that the blood is usually not found in the urine of a healthy person is:

Kidneys are located in back just below the lowest rib. Each kidney is about 4.5 inches long and weighs about 5 ounces. Each kidney contains about a million functional units called nephrons.

<u>Every nephron consists of glomerulus and tubule. Each glomerulus unit functions as tiny filter. Blood in the body passes through these glomerulus, that retains the blood cells and large biomolecules like proteins in circulation while allowing fluid and some small molecules to pass through to tubule. </u>

<u>As the fluid flows through tubules, much of the volume of the liquid is absorbed back in bloodstream. The tubules then join to form collecting system of each kidney. By this point, the concentrated fluid has all characteristics of the urine.</u>

If blood occur in the urine, that means the nephrons cannot function properly which can lead to kidney damage.

Zolol [24]

Answer:

The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.

Explanation:

Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
