Why does the heart need its own vessels when the blood is constantly passing through the interior of the heart?
The endocardium does not allow the passage of O2 and other nutrients to the myocardium because of the watertight endothelium. Additionally, the myocardium is too thick for diffusion to take place across the cells. Therefore another alternative is required.
Generally, in order for any type of tissue to receive and eliminate nutrients and waste products (respectively) the blood must be in small pressure so osmosis can take place efficiently. The blood that passes through the atria and ventricles has very large pressure in order to reach all parts of the body. Therefore, small blood vessels called coronary arteries branch from the aorta (oxygen-rich) and move though the heart muscle. These vessels make sure that the blood passes through very slowly and during the diastole of the heart the cardiomyocytes receive their nutrients.
What else can I help you with?
What is a function that is associated with vessels that carry blood directly from arterioles to veins without passing through capillaries?
Carry nutrients
What jobs the blood does for the body?
It flows round the body, passing blood through your body. It goes through the vessels, collects oxygen and lets the oxygen go in the cirlculation system. :)

When the pressure of blood pumping through the blood vessels is constantly high the condition is known as?
This would mean that the person has high blood pressure and the medical term for this is hypertension.
What passes through the iliac crest?
The ilaiac crest is the rim of a bone - nothing passes through it.
What do our bodies constantly do with the heat we have stored inside us?
Our bodies constantly regulate body temperature through a process called thermoregulation. This involves releasing excess heat through mechanisms like sweating, vasodilation of blood vessels, and increased respiration. By maintaining a stable internal temperature, our bodies can function optimally.
What is the definition of blood vessels?
Blood vessels are any of the tubes through which blood flows through the body.
Is the Suez Canal still used in 2008?
Certainly! It is used constantly by merchant vessels and Navy ships.
What pathway does blood travel through blood vessels?
the blood travel through blood vessels is the Artrium or atria. :-)
What cause the blood to flow through the blood vessels?
The heart is a pump and move blood through the blood vessels.
What are some examples of fluids moving through objects?
Examples of fluids moving through objects include water flowing through a pipe, blood circulating through blood vessels in the body, and air passing through a ventilation system. Fluid mechanics describes the behavior of these fluid movements within different structures and systems.
What vessels are known as exchange vessels?
Capillaries are known as exchange vessels. Capillaries are the smallest of vessels and allow nutrients and waste to pass through blood and body.
