Capillary

Ventilation and perfusion work together in the body to provide oxygen and dispose of carbon dioxide. Ventilation provides tissue and organs oxygen by the process of mechanical inspiration and exhalation of the lungs. This provides the alveoli within the lungs with oxygen, as well as the ability to expel waste products like carbon dioxide. Perfusion provides the tissues and organs with oxygen by the mechanism of diffusion between the pulmonary capillaries and alveoli. Ventilation Ventilation is the movement of air in and out of the lungs, also known as inspiration and expiration as previously stated. Respirations are controlled by the medulla oblongata in the brain. The medulla oblongata initiates the signal for the respiratory muscles to…

Diffusion across this pressure gradient is so effective that the capillary blood is fully oxygenated by the time it has passed through 1/3rd of the alveolar capillary network (Grossman & Porth, 2014). Ficks law of diffusion describes the relationship between factors that influence diffusion rates. It can be used to look at diffusion between the alveoli and this pulmonary capillary network. These factors include the partial pressure difference of gas (p1-p2), the thickness (T) and surface area…

Introduction: Langerhan’s cell histiocytosis is a malignancy caused by uncontrolled proliferation of the Langheran’s cell line with associated granulomatous deposition. The disease exists in a wide spectrum of clinical presentations ranging from localized skin manifestation to diffuse disease with neurological involvement. Typically, diabetes insipidus occurs when the hypothalamic-pituitary axis is affected by histiocytic infiltration. Langheran’s cell histiocytosis can be confirmed by…

A water table marks the top of the saturated zone of groundwater. When something is saturated, it means one substance (Like soil) is filled with another substance (Like water). Therefore, the area filled with water is called the saturated zone. This zone can be called the phreatic zone or the zone of saturation. This is always the zone below the water table. Directly above a water table there is always a capillary fringe. The water table separates the capillary fringe from the zone of…

I chose capillary action because I think that it's most important to our society. Its also a lot easier to understand. Capillary Action is a property of water. It is the ability of water to move upward against gravity. Water moves in between spaces due to forces of adhesion, cohesion and surface tension.Adhesion of the surface the water is sticking to makes the water able to be moved up, surface tension acts to hold the water to the object the water is moving on, and the capillary…

The capillary column is held in an oven that can be modified to build the temperature step by step (or in GC terms, sloped). This helps our partition. As the temperature expands, those compounds that have low boiling points elute from the column quicker than those that have higher boiling points. Subsequently, there are really two unmistakable isolating forces, temperature and stationary phase specified beforehand. As the mixes are isolated, they elute from the segment and enter an indicator.…

help to keep the blood following in one direction, back toward the heart. The activity of the skeletal muscle that surround the veins will create the pressure that derives the venous pump. 2- Functions; - and oxygen the blood in the capillaries into the interstitial flued and then into the cells. Carbone dioxide and other substances move in the opposite direction from the cells into the capillaries. Fluid is also exchanged between capillary blood and interstitial fluid. Two opposite forces…

mortars. The geopolymer binders with WTS and the additional RHA became the mortars more consistent and difficult to mix and mold, and the entrapped air remained in the mortars. Fig. 7 shows the capillary water absorption. The higher the WTS content in the mixture, the lower the capillary water…

On the southwest corner of 6th and Mt. Rushmore, there is a sign that says, "Welcome to Little Italy." The building next to the sign is a quadplex that shares many small businesses. This is a "mom and pop shop" area of town. Just to the north of all these businesses is an area where most of the drug addict and alcoholic population spend their time. This was a crime infested area with king pins in all sorts of drug categories. Our dispatcher received a call on. October 2nd, 2016 about a finding…

This section will discuss capillary bridges in more detail. Capillary bridges are formed under the influence of capillary action, which will be discussed first. Also the forces caused by capillarity are briefly discussed. Next, the characteristics of the particles and their effect on the shape of the bridge are discussed. This is followed by the mechanism of capillary bridge breakup. Finally the process of capillary bridge formation by condensation is discussed. 2.1.1. CAPILLARY ACTION Liquids…
