How does blood circulate in most mollusks?
* Oxygenated hemolymph (blood), coming from ctenidia, flows into heart's atria, * then it flows into heart's ventricle, which pumps the hemolymph into arteries, * from arteries, hemolymph flows into the hemocoel; * then it's caught again inside veins and brought directly into afferent ctenidial vessels or into accessory branchial hearts, which pump it inside ctenidia again, for oxygenation. Hemolymph flows also into the pericardium, the celomatic membrane wich contains the systemic heart, and, from it, hemolymph reaches and flows into the excretory ducts.
How does an open circulatory system allow for the circulation of blood throughout the body?
An open circulatory system allows for the circulation of blood throughout the body by pumping blood into a cavity called a hemocoel, where it bathes the organs directly. The blood then flows back into the heart through openings called ostia, allowing for the exchange of nutrients and waste products with the organs.
Where does the blood flow out of you when you get your period?
Blood flows out of the uterus through the cervix and then out of the body through the vagina during menstruation.
Is it true that with veins that the blood flows from small vessels into even smaller ones?
No. Veins are the portion of the circulatory system that is responsible for returning blood from the body to the heart. Thus blood flow in veins starts at the smallest capillary vessel and moves to larger vessels.
What is the functional nature of a portal system and how does it differ from normal venous return flow?
A portal system is a special type of blood circulation where blood from one capillary bed flows into a second capillary bed before returning to the heart. The hepatic portal system, for example, carries nutrient-rich blood from the digestive organs to the liver for processing. This differs from normal venous return flow where blood goes directly from capillaries to veins and then back to the heart.
Blood normally flows from the capillaries directly into?
small veins.
Blood flow from inferior vena cava back to the heart?
Passively. Blood flows in the inferior vena cava because the pressure in the right atrium is lower than the pressure in the vena cava. Blood flows along this pressure gradient to return to the heart.
Why wear wedding ring on the left hand?
the blood flows through the artery directly from the ring finger to the heart
When was As Blood Flows created?
As Blood Flows was created in 1993.
How does the circulatory system help your cells get rid of carbon dioxide?
The blood flowing through the veins carry the carbon dioxide from the cells of all parts of the body to the heart. Hence we say that the veins transmit the De-oxygenated blood from all parts of the body to the heart. The De-oxygenated blood collected in the heart flows to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs. Then the oxygenated blood flows to the heart through the pulmonary vein. Then the oxygenated blood flows to all parts of the body through the arteries. So blood flows into the heart through the veins, and flows out of the heart through the arteries. Normally the De-oxygenated blood flows through the veins and the oxygenated blood flows through the artery. The only exceptions are the pulmonary artery that transmits de-oxygenated blood from heart to the lungs and the pulmonary vein that transmits oxygenated blood from lungs to heart. This is because blood flows into the heart by veins and flows out of the heart by arteries.
Which is the largest and the main artery of the ciriculatory system?
It is the aorta, the artery that flows directly out of the heart, taking oxygenated blood to the rest of the body. Agreed!!
As venous blood is drained from the kidney which path does it follow?
From the capillaries of the kidney, deoxygenated blood flows through the renal vein. The renal vein empties directly into the inferior vena cava which carries the blood back to the heart.
Why does your face turn red when you stand on your head but your toes don't turn red when you are standing up?
Because your blood flows normally when your standing because your supposed to.
Oxygenated blood flows through the?
It flows inside the pulmonary veins
Which type of blood vessels does the blood flow away from the heart in?
Blood flows away from the heart in arteries, and towards the heart in veins.
What tissue Flows through the heart and blood vessels?
Connective tissue flows through the heart and blood vessels.
