Yes. And to other parts of the body as well. As plaque builds up, the arteries narrow, blood pressure builds. The chance of heart attack and stroke increases the more the arteries narrow.
it moves very slowly
An hot air balloon i think.
semiperable
Blood does not move slowly through the body. Blood moves very fast through the aorta. The speed of blood in aorta is about 50 cm per second. The speed of the blood through the cappilaries is very slow. It is only 0.05 cm per second. The The speed of blood in inversely proportional to the cross section of the diameter of the conducting blood vessels. The total diameter of the capillaries being very large, blood flows slowly through the capillaries. Although the diameter of the individual capillary is very small. But the length of the capillaries is very less. So this is not a problem, but an advantage. You get time for transfer of the nutrients and oxygen, as well as waste products of metabolism and carbon bi oxide. It takes only about 15 seconds for the blood to get back in the same chamber of the heart.
One example of gas effusion is the release of a gas through a small hole in a container, such as when air slowly escapes from a balloon. Another example would be the diffusion of gas molecules through a porous membrane, like the way oxygen and carbon dioxide diffuse in and out of our lungs during respiration.
A helium balloon reduces in size because the helium slowly seeps out through the wall of the balloon.
Capillary beds are finely branched, have smaller diameters, have more inner surface area and therefore offer greater resistance to blood travelling through them than arteries do.
Red blood cells have to pass through capillaries in a single file so the cells move fairly slowly. Because arteries have enough space to allow multiple red blood cells to pass side by side, blood flows fairly quickly. Therefore, blood moves more rapidly in arteries.
Cardiac stent's are good for if someone has blocked arteries the cardiac stent will restore blood flow through the inner wall of the artery. Stents are sometimes coated with medicine to slowly release in the artery.
Bad breath, yellow teeth, tar in your lungs which reduces breathing capacity and therefore stamina when running; spluttering coughs, impotence, fatty deposits around the arteries reducing bloodflow and increasing the risk of heart disease, also money down the drain. You are paying a newsagent to kill you slowly basically.
Yes and No. When Ice is filled with Air it becomes Transclucent, when Ice melts, slowly the Air reduces and it becomes Transparent.
the soil that allows water to pass through very slowly is clay
The viscosity of the fluid controls its flow rate. A higher viscosity reduces the flow.

Borane takes aldehydes to primary alcohols and ketones to secondary alcohols it also reduces esters but only slowly
Impulses travel more slowly through unmyelinated nerve fiber.
Longitudinal (also know as compression) waves travel more slowly through gasses than solids.
