Why is the blood flow in the capillaries slower than the arterial and venous vessels?

The capillaries are smaller and made of a thinner 'material' than arterial, meaning they are unable to take a high pressure from the blood that comes straight from the heart.
Also, I'm fairly sure that this is where things disperse, i.e. capillaries in the lung take oxygen in let carbon dioxide out.
Yep, so main reason is they are smaller, thinner and used to disperse substances into/out the blood.
hope this helped!

∙ 9y agoWhen blood flows through the capillaries it must go slowly. The capillaries are where the oxygen from the red blood cells enters the cells of the body and the cell waste enters the blood stream.

∙ 13y agoThe slow rate of blood flow in the capillaries permits sufficient time for the exchange of gases, nutrients, and wastes through the capillaries.

What is a minute blood vessel between the arterial and venous systems?
Very fine blood vessels are called capillaries.
What exchange blood between arterial and venous systems?
The arterial and venous systems are connected in the body tissues by capillaries, and also in the heart.
What exchanges blood between the arterial and venous systems?
The arterial and venous systems are connected in the body tissues by capillaries, and also in the heart.
The connection points between the arterial and venous systems are called?
Capillaries
Do both arterial and venous vessels have valves?
No. Only venous vessles contain valves.
What are capillars?
capillaries are the smallest of the blood vessels. They connect the arterial system to the venous system and are the site of interaction between the blood and the rest of your body
What is the blood pressure in capillaries?
Generally the blood pressure at arterial end of the capillaries is about 30 mm of mercury. The blood pressure at the venous end of the capillaries is about 15 mm of mercury. The fluid exit the capillaries at arterial end. Fluid enters the capillaries at venous end.
What are conductance vessels?
Conductance vessels distribute blood to and from the tissues. Arterial vessels also damp the pulse prssure, and veins contribute to venous capacitance.
Meaning of artery?
The trachea or windpipe., One of the vessels or tubes which carry either venous or arterial blood from the heart. They have tricker and more muscular walls than veins, and are connected with them by capillaries., Hence: Any continuous or ramified channel of communication; as, arteries of trade or commerce.
The circulatory system consists of a series of vessels called?
Blood vessels come in three types: arterial, capillary, venous; and a fourth is the unidirectional flow of the lymphatic fluid in the lymph vessels.
What happens at an arterial end?
At the arterial end of a capillary bed, blood pressure is higher than at the venous end. This pressure allows nutrients, oxygen, and other essential substances to be pushed out of the capillaries and into the surrounding tissues.
Why arterial blood is more alkaline than venous blood?
pulmonary arterial blood as it has moce CO2 than venous
