If I get what you are asking, the heart pumps blood through the arteries, which are under pressure. The veins have little pressure of their own.
Arteries don't but veins do. that's bcz when blood reaches veins its pressure has considerably decreased and veins r not pulsatile thus to continue the flow to heart it is pushed towards heart with the help of presure caysed by compressing the veins during muscle contracttion and raised presuure during inspiration.

Veins.
Arteries are under pressure from the heart.
In earthworms, blood is pumped by a muscular blood vessel called the dorsal blood vessel. This vessel runs along the top side of the digestive tract and contracts rhythmically to circulate the blood throughout the worm's body.
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
Riding a bike primarily involves the muscular, skeletal, cardiovascular, and respiratory systems. Muscles in the legs create pedaling motion, while the skeleton provides support and structure. The cardiovascular system pumps oxygen and nutrients to the muscles, while the respiratory system supplies oxygen for energy production.
The heart is a muscle that pumps blood around the body.

Lymphatic, Immune and Cardio systems
Your Heart is an organ that pumps blood through your body.
The ventricle is a muscular chamber.It does the actual pumping for the heart. It pumps blood to a large tube:the bulbus arteriosus
The left ventricle is the heart chamber that most directly pumps blood to the vessel network. It pumps oxygenated blood out into the body through the aorta, which then branches out into smaller arteries to deliver blood to the rest of the body.
