ACTIVITY 2 Studying the Effect of Blood Viscosity on Blood Flow Rate 1. Describe the components in the blood that affect viscosity. The plasma, red and white blood cells, and platelets cause resistance as they travel through vessels. 2. Explain the effect that the viscosity change had on flow rate.
Lymphatic System & Disease Resistance 1. Describe lymphatic system functions. The lymphatic system helps fluids circulate the body and helps defend against agents that cause disease. 2. Locate each of the following lymphatic vessels: right lymphatic duct, thoracic (left lymphatic) duct, right and left subclavian veins, and cisterna chyli.
Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
This results from arterial bleeding, cast-off blood or exhaled blood. The third classification is called combination spatter as it is a mixture of the first two (impact and projection). Each person has a certain amount of blood in their body and that amount of blood is proportional to their weight. When blood leaves the body different factors can affect the way it leaves. If there was trauma to the body, the type of trauma is going to have an effect on the amount of blood loss and the speed at which blood leaves the body.
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
Having too few or too many red blood cells can be a sign that you have certain diseases. The hematocrit test, also known as a packed-cell volume test, is a simple blood test. The test is done by drawing blood from the patient into a test tube. Once that is done the test tube is put into a centrifuge and spun in high speeds. This displacement causes the formation of three layers.
The medical resident prepares to draw blood gases from Jackie. The blood gases should be drawn from the: A. central venous catheter Arterial blood is needed for a blood gas analysis. The tunneled central venous catheter is situated in the superior vena cava, a major vein. B. radial artery Correct Freshly oxygenated arterial blood is needed for a blood gas analysis. The radial artery is commonly used to obtain an arterial blood sample.
It is a series of physical reactions that transform liquid blood into a gel that forms a secure patch over the damaged blood vessel. Coagulation has three main stages: Formation of factor x and prothrombinase, Prothrombin is converted to thrombin and finally Fibrinogen is converted to fibrin. The clot is formed by these stages. It is then strengthened by a process called Clot Retraction. This is here platelets in the clot contract pulling on the fibrin strands that they are attached to.
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
Liver Introduction There are many organs that help our body function properly, one particular organ that plays an important role is the liver. According to Dorland’s Illustrated Medical Dictionary, liver is defined as a large gland of a dark red color found in the upper part of the abdomen on the right side. Its domed upper surface fits closely against and is adherent to the inferior surface of the right diaphragmatic dome, has a double blood supply and from the hepatic lobes, left lobe, right lobe, caudate lobe and quadrate lobe (Dorland 1082). Liver is divided into three different regions, left liver (pars hepatis sinistra), right liver (pars hepatis dextra) and posterior liver (pars posterior hepatis), the latter being identical to the caudate lobe. Liver is made up of thousands of minute lobules, which are functional units of the liver.
