Capillaries

Alveoli which are in your lungs

They are found because they have to bring oxygen and nutrients from the veins and arteries to all of the cells. They remove waste (carbon dioxide) from the cells and drop it off at the lungs. Therefore, that's when breathing occurs and the cells get oxygen and do the cycle over and over.

A capillary has a small diameter, which slows the flow of blood. In addition, it has a very thin wall. Together, these structural features facilitate its function of gas and nutrient exchange with the tissues.

Liquid rises in and out of cappilarry to compansate pressure difference.

Rise of a liquid in capillary is indirectly proportional to radius of tube so liquid goes higher in a narrow tube.

This capillary network surrounds the tubules and plays an important role in secretion and reabsorption, plus it delivers oxygen to kidney cells.

A hemangioma is a benign tumor that can involve the body of the vertebra. This tumor is often found in the lower thoracic or upper lumbar spine, usually involving only a single vertebra. Interestingly, not all hemangiomas produce symptoms such as pain. Hemangiomas typically occur during mid-life, affecting females more often than males. The most common symptom associated with a hemangioma is pain. This is typically the result of a large hemangioma involving the entire vertebral body. Hemangiomas may be discovered as part of an evaluation for back pain. They have a very characteristic appearance on regular x-rays, referred to as " honeycombing." There may also be a varying degree of collapse and loss of vertebral height with extensive involvement. When the collapse is severe, impingement on the spinal cord or neural elements will produce severe pain and loss of function in the legs, bowel or bladder. There are a number of treatment options for vertebral hemangioma, ranging from observation to radiation to surgical resection. Treatment decisions are based upon the severity of symptoms or neurologic compromise. The management of a vertebral hemangioma must take into account the generous blood supply of the lesion, and requires careful planning by the surgeon involved in your care before surgical treatment is recommended.
: A hemangioma is an abnormal build up of blood vessels in the skin or internal organs. 1. A vascular tumor, present at birth or developing during life, in which proliferation of blood vessels leads to a mass that resembles a neoplasm; hemangiomas can occur anywhere in the body but are most frequently noticed in the skin and subcutaneous tissues; most hemangiomas present at birth undergo spontaneouos regression. dr.sohaib al adawi

osmotic and hydrostatic forces

Capillaries are very thin and therefore allow the substances to be diffused out of the thin layer of vein/artery. They are also very small and allow for a smaller amount of blood cells to be transported at one which helps to slow them down (also they are further away from heart) and deposit their substances to each cell.

Capillaries carry Oxygenated (oxygen rich) blood and De-oxygenated (oxygen depleted) blood.

because they oxidize the blood for respiration.

They are only one cell thick and have very thin walls, to allow nutrients and oxygen to diffuse out of them.

Capillaries allow the exchange of substances between the blood and the cells. They can do this because they have 'leaky walls' which let substances in and out. For instance food is supplied to the cells and carbon dioxide comes out of the cells to be taken away.

They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.

Glomerulus- tiny ball of capillaries(microscopic blood vessels) in the kidney.

Blood passes through the capillaries, which provide a passage way for the blood from the arteries to the veins. The tiny, thin walled capillaries also allow for the exchange of gases through the tissue. You can read more about capillaries at fi.edu

The capillaries are where the actual transfer of oxygen to the cells happen making it the absolute essential part of the system. The lungs/gills/skin whole job is to get oxygen into the bloodstream so that the capillaries have oxygen to transfer to the cells. The hearts whole job is to supply enough pressure to circulate the blood past the capillaries so it constantly has new oxygenated blood to transfer oxygen to the cells.

Capillaries do not have a thick wall. These are very small, thin, tiny blood vessels. Their main function is to bring blood from larger blood vessels into every furthest part of your body, and to remove cellular wastes from those areas.

There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.

The blood is under low pressure once entering the capillary.

By the time the blood gets to the capillary bed, the blood pressure has dropped very low. This is important since this allows time for oxygen and nutrients to be dropped off and wastes and carbon dioxide to be picked up. By the way, the capillaries are so small that the red blood cells can barely fit through. They have to bend to fit. That also slows things down.
