Shakespeare Sance Homework # 4 The factors that would cause the lung to collapse are elastic recoil and high surface tension. And the factors that prevent the lungs from collapse are negative intrapulmonary pressure and surfactant. During expiration : volume increase and pressure decrease During inspiration : volume decrease and pressure increase The role of surfactant is to decrease surface tension by more than 40 times. And it’s effect on surface tension is to prevent them from PO2

are very important when it comes to the many functions to help maintain the health of the body. This includes the maturation of the red blood cells‚ regulation of blood pressure as well as secretion of hormones. The Secondary functions of the filtration effect the controlling of the acid base balance in the body‚ and maintaining bone health (livingstrong.com).

reduced appetite. There are several types of tests done for CKD. There is a test to take precautions; to check if you even have the disease. That test is either the urine tests‚ or the blood test that is named eGFR‚ which means estimated glomerular filtration rate. Another test that is done‚ it’s when you have CKD‚ which is an ultrasound of the kidney or also known as a renal ultrasound. It helps estimate how long you may have had chronic kidney disease; it also checks whether urine flow from the

Chronic Kidney Disease BIO 105‚ sec M02 Prof. Palanca Ayo Powell (Term Paper) 3/25/12 The Kidney is one of the most important organs in the human body. Its primary function is the removal of waste & toxins from the blood stream. So if the kidney stopped working correctly and is no longer able to properly function that would lead to serious problems. Blood is no longer being cleaned. The waste and the toxins aren’t being removed. Instead it’s all building up in the blood stream causing

will reduce the plasma volume and thus reduce the blood pressure (Widmaier‚ Raff & Strang 2001). The change in blood pressure will be detected by baroreceptor and initiate reflexes that influence the renal arterioles and tubules to reduce glomerular filtration rate (GFR).Renal cells secrete renin that indirectly cause adrenal cortex to increase aldosterone secretion. Increasing in aldosterone will stimulate cortical collecting duct to increase sodium reabsorption and reduces sodium excretion to regulate

A nephron consists of one glomerulus and one U-shaped tubule that drain the waste into the renal pelvis. [4]The glomerular filtration barrier consists of endothelial cells‚ the glomerular basement membrane and visceral epithelial cells. Figure 1 shows the basic anatomy of the kidney. [4] All molecules below the molecular size of albumin pass the filter and enter the tubule. An intricate counter current
