What else can I help you with?
How does the heart pump blood?
Your heart contracts, forcing your blood out your aorta, and through your body.
Valves are found in?
The Heart- Between the Atria and Ventricles Veins- So they help push blood back to the heart against gravity.
What describes the next step after the blood has traveled from the heart to the toes?
The blood returns to the heart through veins.
What circuit carries blood to the body except the lungs for oxygenation and back to the heart?
There are two circuits: Pulmonary-carries blood to the lungs and back to the heart Systemic-carries blood from the body and back to the heart
Which structures carry blood back to the heart?
The veins carries blood from the body to the heart.
What is the work of blood?
the blood vessels are the passageways of blood from the heart and back to it after it circulate around the body.

Do veins leading back to the heart become larger?
yes,to circulate more blood .
How does the heart pump blood?

How does gravity affect your blood?
Gravity affects the circulation of blood in your body by helping to return blood from your lower extremities back to your heart. When you stand upright, gravity pulls blood downwards, making it harder for your heart to pump blood against gravity. This can lead to higher blood pressure in your lower extremities and can contribute to conditions like varicose veins.
What happens after a heartbeat?
The heart has 2 tubes from it, one for the the first beat causing the blood o circulate out, and the other to come back. Causing the blood to go were it needs to.
Valves are found in?
The Heart- Between the Atria and Ventricles Veins- So they help push blood back to the heart against gravity.
How does gravity effect blood pressue?
Gravity affects blood pressure by influencing the distribution of blood in the body. When standing, gravity causes blood to pool in the lower extremities, which can lead to a decrease in blood pressure. Conversely, when lying down, gravity helps facilitate blood flow back to the heart, which can help regulate blood pressure.
Does gravity assist in venous return?
Yes, gravity does assist in venous return by aiding the flow of blood back to the heart. When an individual is upright, gravity helps to push blood from the veins in the lower body towards the heart. This process is important for maintaining proper circulation in the body.
How is blood able to travel upwards against gravity?
Blood is able to travel upwards against gravity due to the pumping action of the heart, the presence of valves in veins that prevent backflow, and the contraction of surrounding muscles that help to push blood back towards the heart. Additionally, the difference in pressure between the arteries and veins also plays a role in facilitating blood flow back to the heart.
Which force must the flow of blood overcome as it moves from the feet back up to the heart through the veins?
Gravity
What is the pumping part of the heart?
The entire heart pumps blood. The blood enters the heart via the superior vena cava, is pumped through the heart's right atrium to the right ventricle. Afterwards, it leaves the heart and enters the lungs. The blood is then sent back to the heart where it enters the hearts left atrium. It is pumped to the left ventricle and finally out of the heart to circulate throughout the body.
