In which blood vessels does diffusion occur?
Capillaries.
Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
What is the blood that supplies the blood vessels?
small blood vessels called Vaso Vasorum these are for large arteries others by diffusion
Vessels that carry blood to the peritubular capillaries?
The main capillaries of the renal cortex which arise from the efferent arteriole after it leaves the renal corpuscle and wrap around the renal tubules, especially the proximal and distal tubules, to supply nutrients and oxygen to the tubules, to carry away wastes from the tubular cells.
What capillaries surround the tubules of the nephron?
Although ultra filtration in the kidney filters wastes such as nitrogenous waste products in the glomerulus from the blood, it also filters nutrients such as glucose and amino acids. Hence, the loop is surrounded by blood capillaries so that previously ultra filtrated nutrients such as amino acids, glucose, and other nutrients can now be reabsorbed back into the bloodstream by diffusion and active transport and not travel down the further kidney tubules which lead to the bladder and later be expelled in the form of urine.
Do paramecium have blood vessels?
Paramecium is a unicellular organism. blood vessels itself are made up of lots of cells. secondly, it does not have any blood. but i think it has tubules with in its body associated with the transport of water and solutes dissolved in it.
Tiny vessels through which diffusion takes place between the blood and the body tisues?
Capillaries
Which layer of skin contains no blood vessels?
The epidermis, or the outermost layer, contains no blood vessels.
Tiny vessels through which diffusion takes place between the blood and the tissues?
Those would be capillaries.
When both vessels contain the same concentration of glucose what happens?
There was no diffusion, because equilibrium was already established.
Why can epithelial cells survive without blood vessels?
They receive nourishment via diffusion of substances from nearby tissue.
Where do epidermal cells get their nutrients?
Epidermal cells receive nutrients and oxygen from the blood vessels in the dermis.
