Veins carry blood away from the heart, while arteries carry blood to the heart. Veins are more muscular than arteries.
<h3>What is
Veins?</h3>
Veins transport deoxygenated blood to your heart and are frequently found near your skin. Because veins lack a muscular layer like arteries, they rely on valves to keep your blood flowing. Veins begin as tiny blood vessels called venules and grow into full-size veins as they get closer to your heart.
Veins are blood vessels that carry blood to the heart in humans and most other animals. Most veins return deoxygenated blood from the tissues to the heart; the pulmonary and umbilical veins, on the other hand, return oxygenated blood to the heart.
Veins transport blood to the right side of the heart. The pulmonary arteries transport blood to the lungs, where it receives oxygen.

At the neuromuscular junction, the arrival of acetycholine on the muscle most immediately causes a graded depolarization. Graded potentials are the changes in membrane potential that vary in size, as opposed to being all or none. Graded potential can be depolarizing or hyperpolarizing depending on the stimulus. Action potentials on the other hand always lead to depolarization of membrane and reversal of the membrane potential.
Answer:
In photosynthesis, water, carbon dioxide, and energy in the form of sunlight are inputs, and the outputs are glucose and oxygen.
