What is the role of capillaries in the digestive system?
to move nutrients to the individual cells of the body
What is the function of astrocytes cells?
Astrocytes are star shaped glial cells because of cytoplasmic processes that extend from the cell body. They play a role in regulating the extracellular composition of brain fluid. They release chemicals that promote the formation of tight junctions between the endothelial cells of capillaries.
Describe the role of the choroid plexus in the blood-brain barrier?
The choroid plexus is in contact with the cells lining the ventricles, which helps in the formation of cerebrospinal fluid. The capillaries of the choroid plexus differ significantly from those found elsewhere in the body. As a result, drugs carried in the bloodstream may not effectively penetrate brain tissue. This phenomenon is referred to as the blood-brain barrier. In short, the choroid plexus helps create the barrier, as it is through it's capillaries that the barrier is formed.
What is the role of red cells?
Red blood cells are highly specialized for oxygen transport. They lack a nucleus and instead, contain many copies of hemoglobin. Red Blood cells move single file through the capillaries
The lymphatic capillaries are?
The lymphatic capillaries are small, thin-walled vessels that collect excess tissue fluid (lymph) from the interstitial spaces and return it to the bloodstream. This helps maintain fluid balance in the body and plays a crucial role in the immune system by transporting immune cells and proteins.
What does peritubular capillaries do?
This capillary network surrounds the tubules and plays an important role in secretion and reabsorption, plus it delivers oxygen to kidney cells.
What is the role the capillaries?
exchange of nutrients and gasses with tissues

What is the role of the capillaries?
Capillaries are very small blood vessels found within the tissues of the body. Its primary role is to transport blood from arteries to the veins.
What is the role of the mini-valves in lymph capillaries?
Increase permeability
Ciliated CNS nuroglia tht play an active role in moving CSF are?
Ependymal cells are arranged in single-palisade arrays and line the ventricles of the brain and central canal of the spinal cord. They are usually ciliated, their cilia extending into the ventricular cavity.
