blood pressure in the cappilaries forces part of the plasma out through the walls .the fluid which escapes is not blood or neither plasma but is called tissue fluid by Rachael magro
Cappilaries
It transports blood cells into different parts of the body.
exchage of materials between blood and tissues occur in cappilaries.
Capillaries are the smallest blood vessels. They connect arteries and veins.
cappilaries
Blood
the blood absorb oxygen in the lungs(cappilaries)
The type of blood vessel with the highest percentage of smooth muscle and greatest resistance is the arteriole. Arterioles regulate blood flow to various tissues by constricting and dilating, which allows them to control resistance and blood pressure. Their thick smooth muscle layer enables them to respond to various signals, making them crucial for maintaining systemic blood pressure and directing blood flow.
The growing baby has wastes and needs oxygen and nutirnets through out its time in the womb... The placenta holds many tiny cappilaries( very small blood vessels) Half are babies, and half are moms. These blood vessels run very close to each other.. The oxygen and nutrients that the baby needs are diffused from the mothers cappilaries to the babys cappilaries. In other words the oxygen and nutrients in the mothers blood is passed to the babys blood with out touching, the tiny particles are small enough to go through the walls of the cappilaries. These much needed nutrients are then taken to the baby through the imbilical cord. The baby also makes many waste products, carbon dioxide, urea(what makes up most of urine), extreme amounts of water, and salt are a few.. These waste go through the imbilical cord, to the babies tiny cappilaries in the placenta. Then it diffuses into the mothers cappilaries in the placenta.. The mother then gets rid of these waste products.
