the coronary arteries
Which blood vessels contain blood that is higher in oxygen?
-Pulmonary Veins
arteries
inferior vena cava
Heart
The systolic pressure is the highest pressure measured against the walls of blood vessels.
The cornea, the clear part of the eye, does not contain blood vessels and it receives oxygen supply directly from the air.
The highest pressure against the blood vessels is Systolic Pressure, and it occurs when the ventricles contract.
The area of the head and skull with the greatest concentration of vessels is the scalp. The scalp is highly vascularized to supply blood to the hair follicles and the skin of the head. This rich blood supply helps nourish the hair and provide a protective barrier for the skull.
In fact, the kidney dose not receives the urine but it produces the urine by receiving the filtrate from the blood vessels . and the first part wich receives the filtrate is the " glomerus"
The blood vessels that contain the highest concentration of amino acids are typically the portal veins, specifically the hepatic portal vein. This vessel carries nutrient-rich blood from the gastrointestinal tract and spleen to the liver, where amino acids absorbed from digested proteins are transported. The liver processes these amino acids for various metabolic functions, resulting in a high concentration in the portal circulation before they enter systemic circulation.
The heart muscle is supplied by blood vessels called coronaries.
The part of your eye that receives no blood at all is the cornea. This is the clear and transparent part of the eye and it does not have any blood vessels.
Epithelial tissue lacks blood vessels. Instead, it receives nutrients and oxygen through diffusion from nearby blood vessels in the underlying connective tissue.
