By What is the cross section of an artery?
Cross-section of an artery showing inner, middle, and outer layers. The intima is a layer of endothelial cells and connective tissue which covers the luminal surface of the arteries. The media consists of connective tissue (tissue full of collagen, elastin, and other elastic fibers) and smooth muscle cells.
What travels through an artery?
The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
Do arteries have a large cross sectional area?
There are four main types of vessels in the body and have a specific role in blood flow. Arteries are thick-walled vessels that perfuse organs. Capillaries connect arteries to veins and are the main sites of nutrient/waste exchange. Capillaries have the largest total cross-sectional and surface area.
Which artery carries blood to the heart?
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …
How do you tell the difference between a vein and an artery?
Your arteries are thicker and stretchier to be able to handle the higher pressure of blood moving through them. Your veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.
Which blood vessel has the smallest cross-sectional area?
aorta
The cross sectional area, of any part of the vasculature is taken as the sum of all the vessels at that level and not of a single vessel individually. Hence, the aorta which is a single vessel, has the smallest cross sectional area of 2.5cm^2.
What are the 3 main arteries in the heart?
The coronary arteries are also called the epicardial arteries because they run along the outer surface of the heart on the epicardium; the main ones are the left coronary artery and the right coronary artery.
Where are the blood vessels located in a cross section?
The neurovasculature of the arm lies medially in this cross section. Moving medially away from the humerus one can see the brachial artery, brachial vein, basilic vein, median nerve and ulnar nerve. The blood vessels are easier to spot than nerves due to their larger diameter. The radial nerve is located posterolateral to the humerus.

How is blood transported from the heart to the arteries?
Blood is transported in arteries, veins and capillaries. Blood is pumped from the heart in the arteries. It is returned to the heart in the veins. The capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls. Arteries carry blood away from the heart.
How are the capillaries and arteries connected to the heart?
Structure and function of blood vessels. Blood is transported in arteries, veins and capillaries. Blood is pumped from the heart in the arteries. It is returned to the heart in the veins. The capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls.
