Why are leydig cells located close to the capillaries?
because they are hormone-secreting and so they have to be in close contact with blood vessels
What is the main function of the capillaries?
Capillaries are one-cell wide blood vessels. They allow intimate close-contact with muscle and other body cells with red blood cells. It is in capillaries that oxygen exchange occurs. In close contact with muscular myoglobin, adult hemoglobin releases its oxygen and myoglobin picks it up.
What are platelets and what is its function?
Platelets are nuclear cells rotates the blood and get rid of blood clots.they release protein , and close up the tear in the blood vessels..
Why are there blood capillaries close to all the cells in your organs?

What is the advantage of the structure of the lung tissue?
The tiny sacs insure that the maximum area of tissue can be in close contact with the blood vessels to facilitate gas transfer
Why does blood goes to the capillaries before to the cells?
Blood flows to the capillaries before reaching the cells because capillaries are the smallest and most abundant blood vessels, facilitating the exchange of oxygen, nutrients, and waste products. This extensive network of capillaries provides a large surface area and ensures that blood comes into close contact with cells, allowing for efficient diffusion. By reaching the capillaries first, blood can deliver essential substances directly to the tissues and remove metabolic waste effectively.
What do you call the small vessels that are close to your cells?
one of them is the capillaries
Does close circulatory systems have blood that does not flow in defined blood vessels?
no it doesnt
How do nerve cells get blood and oxygen?
Nerve cells receive blood and oxygen through a network of small blood vessels called capillaries. These capillaries are located close to nerve cells in order to deliver nutrients and oxygen for their metabolic needs. The brain, for example, has a dense network of capillaries to ensure a constant supply of blood and oxygen to nerve cells.
Close examination of an organ reveals a lining of several layers of cells The layers do not contain any blood vessels and one surface of the cells is open to the internal cavity of the organ This ti?

How does your pulse beat?
When the heart beats it causes blood to flow through the blood vessels which causes them to expand. This expansion can be felt by touching the vessels that are close to the skin.
Can you explain why I can see blood vessels in my vision?
You can see blood vessels in your vision because the blood vessels in your eyes are close to the surface and can sometimes cast shadows on the retina, which is the light-sensitive tissue at the back of your eye. This can make the blood vessels appear as dark lines or spots in your field of vision.
