What else can I help you with?
What is the pathway of blood from the femoral artery to the lungs?
Via abdominal aorta.
How do you trace the pathway of a blood from the aorta to the left occipital lobe?
Aorta...brachiocephalic trunk...common carotid...external carotid...occipital artery...left occipital lobe
The pathway of oxygenated blood and deoxygenated blood through the heart?
Pulmonary vein, left atrium, left ventricle, aorta, arteries ,then to the capillaries
What part of the heart opens to allow blood in?
The heart valves open when blood is flowing through. They close to prevent backflow.
Why don't arteries have valves?
The blood pressure and flow rate in veins is low. When the blood in them is moving upwards (e.g. in the legs) it can stagnate and may have a tendency to flow backwards in the vein. The valves prevent this back flow by closing. The blood pressure and flow rate in arteries is high. Blood flow in the arteries cannot stagnate.
What is the pathway of blood from the femoral artery to the lungs?
Via abdominal aorta.
What are the main blood passages to the heart?
pulmonary and aorta valves.
What vessels transport blood toward the the heart and have valves?
veins
What is the role of valves?
prevent the back flow of blood from ventricle to aorta
What do the aortic valves do?
It prevents the blood already in the aorta from going back into the heart.
What are the structures inside the veins that keep the blood from flowing backwards?
The aortic valve. When the left ventricle contracts, blood is ejected into the aorta. When the left ventricle relaxes the aortic valve stops blood from flowing from the aorta back into the left ventricle.
The aorta connects to the heart at the site of the what valve?
The valve in this area is one of the semilunar valves called the aortic valve. These valves look like 3 little cups that collapse and allow blood flow from the left ventricle into the aorta (and from there it supplies a lot of your tissues and organs) when the heart pumps. After the blood moves into the aorta, the little cups expand and prevent the back-flow of blood back into the heart from the aorta.

The largest pathway of the circulatory system?
The largest pathway of the circulatory system is the aorta, which is the main artery that carries oxygenated blood from the heart to the rest of the body. It is the largest artery in the body and branches out into smaller arteries to supply blood to various tissues and organs.

Aorta...brachiocephalic trunk...common carotid...external carotid...occipital artery...left occipital lobe
