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.
It is important that blood moves slowly through capillaries because it allows for efficient exchange of nutrients, gases, and waste products between the blood and tissues. Slow movement provides more time for these exchanges to occur, ensuring that cells receive what they need and can get rid of waste effectively.
to allow for molecular exchange between the blood and the tissue
It is important that blood move very slowly through the capillaries because its a tight place if it goes to fast it throws everything off track and can cause serious damage = )
Blood pressure is much lower in the veins than in the arteries.

Why is the small size of the capillaries surrounding the alveoli important physiologically?
The size of the capillary is smaller than the red blood cells. The exact reason for this is not known. The red blood cells get folded when they pass through the capillaries. This phenomena buy time for the blood to flow through the capillaries, probably. Secondly it will create larger surface area of total number of capillaries to flow the same amount of blood. You have better exchange of gases through larger surface area.
Where are carbon dioxide and blood in the body?
CO2 exchanged to blood through capillaries and blood to alveoli
What do the capillaries carry to the body cells?
Capillaries are very thin blood vessels. Oxygen and nutrients and hormones can pass through the walls of the capillaries and reach the body's cells, while red blood cells remain in the capillaries.
What does the hemoglobin in red blood cells release as blood travels through the capillaries?
As red blood cells travel through capillaries oxygen is released (disassociated) with hemoglobin. The oxygen then diffuses down it's concentration gradient into the tissues.
Why mosquito feeds from a capillary and not from an artery?
Mosquitoes feed from capillaries because the blood flows more slowly in capillaries, making it easier for the mosquito to extract blood. If they were to feed from an artery, the high pressure of the blood flow would make it difficult for the mosquito to access the blood.
Why is it important that blood move slowly through the capillaries?
It is important that blood move very slowly through the capillaries because its a tight place if it goes to fast it throws everything off track and can cause serious damage = )
What is the velocity of blood in the capillaries?
Blood flows slowly through capillaries. This speed allows for increased efficiency of diffusion of materials.
Why does blood move faster through your capillaries?
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
What are Cell fragments that prevent blood from leaking through capillaries?
Platelets are cell fragments that prevent blood from leaking through capillaries
Why white blood cells pass through capillaries while red blood cells not?
Both red and white blood cells pass through the capillaries.
Why does blood flow slowly in capillaries?
Because they have a larger surface area than the other blood vessels.
Why is the small size of the capillaries surrounding the alveoli important physiologically?
The size of the capillary is smaller than the red blood cells. The exact reason for this is not known. The red blood cells get folded when they pass through the capillaries. This phenomena buy time for the blood to flow through the capillaries, probably. Secondly it will create larger surface area of total number of capillaries to flow the same amount of blood. You have better exchange of gases through larger surface area.
What passes through the thin walls of the capillaries?
Blood passes through the capillaries, which provide a passage way for the blood from the arteries to the veins. The tiny, thin walled capillaries also allow for the exchange of gases through the tissue. You can read more about capillaries at fi.edu
Red blood passes through the smallest what in single file?
The tiniest tubes that carry blood are the capillaries. These connect arteries and veins.
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Resistance to blood flow through blood vessels is a function of?
capillaries
Where does the blood flow through?
Veins and artery's and Capillaries
