Hydrostatic Pressure

If blood flow stops, than the chance of death might take place within minutes due to the impact of unfavourable environment on highly disposed cells (Klein & Carson, 2007).

In human, blood is a freely flowing and opaque red fluid, but thicker and stickier as compared to water. It characteristics in terms of colour is imparted through haemoglobin, being a unique iron containing protein. Thus, the erythrocytes (red blood cells) established around 45% of blood volume, and left over cells (including white blood cells or platelets, and leukocytes or thrombocytes) less than 1%. The portion of fluid, plasma is often sticky and in yellowish type liquid. After a full of fat meal, the plasma briefly seems like turbid (Klein & Carson, 2007).

The total

Such opposing hydrostatic pressure is known as the Interstitial Fluid Hydrostatic Pressure (IFHP). In general, the CHP originating from arterial pathways is higher as compared with IFHP as lymphatic vessels are constantly absorbing extra fluid from tissues. Therefore, generally fluid moves away from capillary and enters into interstitial fluid; this method is known as ‘filtration’.

6.2 Explain Oedema and some Possible Causes

Oedema is a medical term that is used for swelling. Basically, it is a common body response towards inflammation or injury. Oedema can be insulated affecting entire body or to small area. Pregnancy, medications, infection and other various medical issues can lead cause oedema. Oedema occurs whenever small blood vessels become ‘drippy’ and started to release liquid into nearby tissues. Thus, the additional fluid is accumulated that causes the tissues to swell (Edwin & Williams, 2006).

Causes of

As an example, a twisted ankle, skin infection or bee sting will cause Oedema in that certain area. Under certain cases, like in infection, this might be advantageous. Rising fluid from blood vessels ensures more white blood cells that are perhaps more infection fighting cells to arrive the affected zone. Oedema can also be caused from some medical problems or conditions in the stability of substances usually exist in blood. Some Oedema cause involves:

• Low Albumin (hypoalbuminemia): Albumin with other proteins present in blood act in the form of sponges for keeping fluid in blood vessels. Low Albumin might contribute to Oedema, but it is not the major cause.

• Allergic Reactions: Oedema is normal component of most allergic reactions. As a result to allergic exposure, the body allows near blood vessels to outflow fluid into affected part.

• Barrier of flow: if fluid drainage from body part is blocked, than fluid can support. A presence of blood clotting in deep veins with in the leg causes Oedema. A blood flow or tumor blocking lymph will result in Oedema in that affected part of the
