I assume you mean the function of blood vessels. The purpose of blood vessels is to carry blood and circulate all around that body bringing blood all around. Within the blood is oxygen, and all the different parts of your body, and more specifically all the cells that make up the parts of your body, cannot live without that oxygen. That's why if you put something tight around your finger, so tight that the blood vessels can't circulate into the finger carrying the blood which is carrying the oxygen, the finger will turn gray and eventually fall off. That's because it didnt get any oxygen.
it separates solid and liquid particles to the vessels.
The coronary circulation refers to the network of blood vessels that supply the heart muscle with oxygen and nutrients. It includes the coronary arteries and cardiac veins. These vessels ensure that the heart receives the necessary blood flow to function properly.
The capillary is the smallest type of the vessels . it consists only of two epithelial cells. and its main function depends on its permeability . so , it is the main site for exchange of nutrition and gases. from the tissues to the circulation and from circulation to the tissues .
The function of the circulation unit in the human body is to transport oxygen, nutrients, and waste products throughout the body via the blood vessels, ensuring that all cells receive what they need and waste is removed efficiently.
how
The coronary circulation refers to the heart. The systemic circulation refers to the other vessels in the body.
the right coronary arteries (cornary circulation)
The function of blood is what it does in the body (carries O2, CO2, food, hormones water etc.) and the circulation of blood is how it gets round the body (pumped by the heart through arteries and veins) to perform its function.
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as coronary veins.
The vessels through which lymph finally rejoins the general circulation are called lymphatic ducts or lymphatic vessels. These ducts empty lymph into the bloodstream near the neck.
the job of blood vessels is for the circulation of blood around the entire body.
Hemoglobin molecules function as the carrier in the human blood circulation system.
