What else can I help you with?
Which blood vessels are in close contact with body cells?
capillaries
What is the fine blood vessel lying close to the body cells?
capillaries
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
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.
What is close to all living cells in the body?
There are blood capillaries close to all of the cells in our body, so that the cells can get all of the energy they need to survive.Blood capillaries are only one cell thick, so that nutrients and oxygen can pass through them easily.
State one significance of having sush s largr network of capillaries?
All the body cells can stay close to the capillaries for the exchange for materials with the blood
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 do you call the small vessels that are close to your cells?
one of them is the capillaries
Have very thin walls to allow exchange of materials between blood and body cells?
Capillaries have very thin walls to allow for efficient exchange of materials between the blood and body cells. This thinness enables the transfer of gases, nutrients, and waste products through a process called diffusion. The close proximity of blood to body cells in capillaries maximizes the effectiveness of this exchange.
What is the difference between open and close circulatory system?
Closed circulatory systems have blood that does not flow in defined blood vessels. Examples are insects and how their organs are bathed continually in "blood". Open circulatory systems have blood that flows in vessels. Humans have this system as blood flows in veins, arteries and capillaries.
What is the close circulatory system and open circulatory system?

What would happen if you didnt have capillaries?
If we didn't have capillaries, we would die. This is because CAPILLARIES are the passageways between the arteries (carrying oxygen- rich blood AWAY from the heart) and the Veins (carrying oxygen- poor blood back INto the heart). Capillaries come in close contact with the body's organs. They exchange their oxygen- rich blood (provided by the arteries) with the organ's oxygen- poor blood (containing carbon dioxide). Thus, the body's organ supply of oxygen- rich blood is replenished. Then, the capillaries give their oxygen- poor blood (from the organs) to the Veins, which bring the blood back to the heart, so it can be filled with oxygen again. It's all a big cycle, and our capillaries play a big role in this cycle. The heart, blood, and blood vessels (arteries, veins, and CAPILLARIES) are all a part of the amazing Cardiovascular System! (Also known as Circulatory system) We really need those Capillaries !! So... What would happen, you ask? Well, the blood in the arteries an the blood in the veins would mix. That is very bad. Our body could not survive if oxygen-rich blood and oxygen- poor blood mixed. We have the capillaries to ensure they never interact!!
