    use a hot plate, water bath, alcohols, ketones, and alkalines, a test tube, capillaries, and a test tube cap. Once the water was boiling, we lowered the test tube into the water and waited until the chemical began to boil. Once the chemical began to boil we removed the test tube from the water bath.

    kidney through the renal artery entering the glomerulus within the Bowman’s capsule. However, when traveling into the glomerulus it is split into fifty capillaries, which has thin walls. The solutes within the blood are filtered through the thin walls by the pressure gradient exiting between the fluid in the Bowman’s capsule and blood capillaries. The pressure gradient is regulated by the dilation or contraction of the arterioles. After traveling through the afferent arteriole the now filtered…

    cells of the human body. This hard working organ, fully matured is only about the size of your clenched fist. Each cell produces waste products and carbon dioxide. The hearts job is to deliver oxygen and nutrients through arteries, arterioles and capillaries to those cells and remove the produce. Blood is then returned to the heart through venules and veins. Arteries are responsible for moving blood away from the heart. Within most arteries is oxygen, except the pulmonary arteries, they carry…

    The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum…

    Blood-Brain Barrier The blood–brain barrier (BBB) is a highly specific permeable barrier that separates the blood from the brain extracellular fluid (BECF) in the central nervous system (CNS). The BBB is composed by brain endothelial cells, which is connected by tight junctions with high electrical resistivity . The BBB allows passage of water, gases and lipid soluble molecules by passive diffusion and selective transport of molecules such as glucose and amino acids . The blood–brain barrier…

    The kidneys are a pair of bean shaped organs that sit to each side of the vertebral column, with the left kidney situated slightly lower than the right. Remarkably, the pair of organs are able to process in the region of 1700 L of blood a day whilst only weighing approximately 113 – 170g (Porth, 2005). The blood is supplied to each kidney via a renal artery branching off from either side of the aorta (Martini, 2006), the renal artery then divides into segmental arteries that sub-divide into…

    Chronic inflammation in the airways limits the amount of airflow to the lungs. It is progressive and relates to abnormal inflammatory response in the lungs that affects gas exchange. “This is caused by loss of elastic recoil and airflow obstruction caused by mucosal hypersecretion, mucosal edema, and bronchospasm”.
