Capillaries
The blood vessels that carry blood to the heart are called veins. There are two other kinds of blood vessels. Capillaries allow body tissues to exchange water and chemicals with blood, and arteries carry blood away from the heart and back out to the body.
The blood cells must move through the capillaries in a single file line because the diameter of the capillary is only slightly larger than the diameter of the blood cells - there isn't room for two blood cells to go through side by side.
Your blood is not single-celled, is is muti-celled because all of the red blood cells in your blood.
The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream
Yes, blood types are inherited through genetics of your parents and ancestors.
It shows how small the blood vessels are
Cardiac volume is the blood pumped in a single contraction
the blood travel through blood vessels is the Artrium or atria. :-)
The heart is a pump and move blood through the blood vessels.
The tiniest tubes that carry blood are the capillaries. These connect arteries and veins.
Microvessels, such as capillaries, are so small that blood cells must pass through them in single file. This allows for efficient exchange of oxygen and nutrients between blood and tissues. The small size of these vessels also facilitates the removal of waste products from tissues.
Blood is the only fluid connective tissue in our body. It passes through every single blood capillary, tissue, and organ in our body. Hemoglobin in our red blood cells carry oxygen which is essential to the function of all the organ systems in our body.
