Blood normally flows from the capillareies directly to what?

Blood normally flows from the capillaries directly to the venules, which are small blood vessels that connect the capillaries to the larger veins in the circulatory system.


Starting at the right atrium in what order does blood flow through the four chambers?

The Deoxygenated blood flows from the body into the right atrium. Oxygenated blood from the lungs flows into the left atrium. Since frogs have only one ventricle, the oxygenated and deoxygenated blood mixes in the ventricle. From there, blood flows into the truncus arteriosus that contains a spiral valve to separate and lead the blood out into the body.


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.


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.

Does Mother's blood flows into the foetus through placenta.True or False?

False. The mothers blood flows through the placenta in vessels next to the foetal blood that flows in separate vessels. Oxygen and nutrients can flow from the mothers blood into the foetus' blood and carbon dioxide and waste products can flow from the foetus' blood to the mother's blood through the vessel membranes, however the two bloods will never actually mix.


Do the father blood flows in the baby vain?

No. The mother's doesn't either. What the father gives to the baby is DNA. The mother's egg carries all cell organelles plus her DNA. When the baby is forming the placenta its' blood supply is separate from the mothers'. However, the two form a capillary bed which allows the baby to get oxygen and nutrients and drop off wastes and carbon dioxide for the mother to dispose.

How an unborn baby get nourishment?

A baby gets all of his food, as well as his oxygen and water, from its mother's bloodstream. The baby's waste products (like C02) are disposed of in the mother's blood stream as well. It is a two-step process.In the placenta, the mothers blood flows in to a network of blood vessels and capillaries. Molecules in the mother's blood like glucose, proteins, fats, oxygen, etc. flow out of the mother's blood supply and are absorbed into another network of blood vessels and capillaries containing the baby's blood supply. The baby's blood then flows through the umbilical cord back to the baby.So when the mother eats a hamburger or a banana, the molecules of glucose, proteins, fats, vitamins, etc. are absorbed into the mother's blood stream by her small intestine. The molecules flow to the placenta, are transfered to the baby's bloodstream and flow to the baby through the umbilical cord.That is why proper nutrition is very important for the mother and the baby.
