What are the two types of veins?
Your body consists of two types of veins. The pulmonary and systemic vein.

Pulmonary veins: Pulmonary veins are major blood channels that transport oxygenated blood from the lungs to the rest of the body. The pulmonary circuit carries deoxygenated blood from your heart to your lungs.
Systemic veins: The systemic…[Read more]

Are veins bigger than arteries?
Your veins are thinner and less stretchy.  The blood in your arteries travels more swiftly. Your arteries are thicker and stretchier to resist blood pressure. Your veins are smaller and less…[Read more]

Why are veins thinner than arteries?
Veins have much thinner walls than arteries, largely because the pressure in veins is so much lower. Veins, like arteries, have three layers. Despite all these layers, you can find less smooth muscle and connective tissue here. The walls of your vein walls are way thinner than artery walls because the pressure…[Read more]

How are arteries and veins similar?
Arteries and veins are components of the body’s circulatory system. One of their similarities is that the walls of arteries and veins are largely composed of living cells and their products (including collagenous and elastic fibers); the cells require nourishment and produce waste. Another is that both of the…[Read more]

Firstly the direction of blood flow for arteries is downward from the heart to the body tissues. The veins carry blood from the body tissues to the heart upward. Next is that the arteries are in charge of transporting oxygenated blood away from the heart to various organs. On the other hand, Veins transport deoxygenated blood from multiple org…[Read more]

Accuracy and precision can be two measures of observational error. Accuracy is how close a given set of measurements (observations or readings) are to their true value. Precision is how close the measurements are to each other.

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body.

An arrhythmia is a heart rhythm that isn’t normal. Your heart may be beating too fast when you’re at rest or just not beating in a regular pattern, for example. Arrhythmias range from harmless to serious, with symptoms and without. There are many options to treat arrhythmias, but some don’t need them. The prognosis varies greatly depending on the type.
