Nephron

Everyone’s kidneys filter their blood, and excrete toxins out of their bodies. Some people have a condition that causes their kidneys to not function properly. The symptoms for this condition are often overlooked or ignored because not many people recognize the symptoms. Many people do not realize how vital their kidneys are in everyday life. Chronic Kidney Disease is a serious condition that can be life threatening. CKD can result in kidney failure. It is a progressive condition that can be…

The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

From the microscopic filtration mechanisms of a single nephron unit, to the multi-organ impact the kidney has on the whole body, I find that the renal system is an indispensable part of the human body that affects every aspect of our lives and it is why a good quality of life is hugely dependent on a good working…

in air, oxygen is diffused from the lungs into the bloodstream, while when you breathe out carbon dioxide diffuses into the alveoli and is then removed from the body. The kidney diffuses water out of the urine through the filtration system called nephrons (Reasoner 2011). The digestive system is another region where diffusion occurs. After we consume food, the nutrients that are absorbed by the cells are transferred and carried through the vessels on the other side of the membrane. This is where…

The treatment of pediatric renal tumors has been improved with minimally invasive and nephron sparing approaches. Development of potential tumor markers and advancements in the delivery of chemotherapy have also increased the survival rate. As cross sectional imaging as developed, risks have been minimized by foregoing unnecessary treatments…

YSTEMIC LUPUS ERYTHEMATOSUS (SLE) SLE stand for Systemic Lupus Erythematosus. The Latin word for lupus means “wolf” while Erythematosus means “red rashes”. Red rashes on a patient’s face that looked like wolf bites was discovered by Dr. Cazenave in 1851 and he named it Discoid Lupus Erythematosus (DLE) which only involved the skin. In 1885, Sir William Osler recognized that many people with lupus had a disease involving not only skin but many other organs or systems, so he named the disease…

What is homeostasis? Many may say it is a state of balance or sometimes a state of equilibrium. But those two things are not the only meaning of homeostasis, hence homeostasis can refer to the approach of an individual’s mortal parts including its capability of cultivating a stabile atmosphere which is fundamental to its continuance. For example, “temperature regulation and oxygen consumption” Schulkin (2002). Therefore, homeostasis is mandatory to human cells by reason of them being systematic…

After going through today’s lesson, in my opinion, I find that negative feedback mechanism is more important than positive feedback mechanism. Both mechanisms are important to the body, but I feel that negative feedback mechanism is more crucial to the body than positive feedback mechanism. Here is why. The positive feedback mechanism is only used when there is a potentially dangerous situation or a stressful process which must be completed quickly. Moreover, our body only uses the mechanism in…

Long term calcineurin inhibitor use can result in cellular changes such as arteriolar hyalinosis, ischemic glomerulosclerosis, and interstitial fibrosis. Chronic allograft nephropathy is the result of incremental and cumulative damage to the nephrons and it is the leading cause of kidney transplant failure. Another cause of nephropathy is contrast-induced nephropathy. It is defined as the impairment of renal function and it is measured as either 25.1mg/dl in serum creatinine from the baseline…
