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.

Arteries are under pressure from the heart.
The heart pumps blood, and it is transported by your veins and arteries.
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the body :)
Your Heart is an organ that pumps blood through your body.
The heart is a muscle that pumps blood around the body.
Lymphatic, Immune and Cardio systems
The heart is a muscle, but it is NOT in the muscular system, and pumps blood to all parts of the 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 pumps blood to all parts of the body and it is more muscular because of the pressure and force required to do this.
The Circulatory System pumps blood and the Respiratory and Digestive System carry it though your body.
