Fast
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
Lymph moves in one direction to prevent pathogens from flowing through the entire body. the system filters out microorganisms as the lymph passes through the various capillaries, vessels, and nodes.
Platelets are cell fragments that prevent blood from leaking through capillaries
True
Both red and white blood cells pass through the capillaries.
No, capillaries do not have non-return valves. Non-return valves are found in veins to prevent blood from flowing backwards. Capillaries function to allow the exchange of nutrients and waste products between blood and tissues.
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
The tiniest tubes that carry blood are the capillaries. These connect arteries and veins.
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.
capillaries
Capillaries are not open all the time to regulate blood flow and maintain blood pressure. By being able to constrict or dilate, they can control the amount of blood flowing through the tissues according to the body's demand, whether it be during rest or when more oxygen and nutrients are needed during physical activity.
