Hypertension is a common health problem especially among people over age of 60 years. This disease is diagnostic when a patient blood pressure is more than 140 to 159 over 90 to 99. Blood pressure refers to the pressure that blood applies to the inner walls of the Diabetes is an endocrine system disorder that occurs when the body is unable to control or balance the amount of sugar in blood and within bodily tissues. You know that the human body is like a machine‚ with organ systems that are specialized

Chapter 3 Homeostatic Imbalances 3.1 Definite changes occur in the glycocalyx of a cell that is becoming cancerous. In fact‚ a cancer cell’s glycocalyx may change almost continuously‚ allowing it to keep ahead of immune system recognition mechanisms and avoid destruction. (Cancer is discussed on pp. 145-146) 3.2 Selective permeability is a characteristics of healthy‚ intact cells. When a cell (or its plasma membrane) is severely damaged‚ the membrane becomes permeable to virtually everything

Dialysis is the process by which waste products are removed from the body by artificial ways by diffusion. The process of removal of waste products in a healthy person is facilitated by the kidneys.

Stenosis means "closing in" or "choking". Spinal stenosis describes a condition in which the nerves in the spinal canal are closed in‚ or compressed. The spinal canal is the hollow vertical hole formed by the bones of the spinal column. Anything that causes this bony hole to shrink can squeeze the nerves inside. This narrowing can irritate the nerve roots that branch out from the spinal cord‚ or it can squeeze and irritate the spinal cord itself. This may cause pain‚ numbness‚ or weakness‚ most

Unit 1. Assignment 1. Homeostatic Imbalances Ericka Keil 3-26-13 A & P Homeostasis is the maintenance of somewhat stable conditions inside the body. Each and every body structure contributes in some way to keep the inside of our body’s and its functioning within normal limits. It is extremely important for proper functioning of all the human body systems. Sometimes our body fails like with Diabetes for example. Glucose is the main sugar that comes from the digestion

monitors and controls the body temperature. The blood glucose concentration is concentrated by the pancreas‚ which produces a hormone known as the insulin; this hormone is able to reduce the blood glucose levels. If there is not enough produced then the disease diabetes is developed. Negative feedback mechanisms: ‘a body system that monitors a system output‚ that shuts off once an optimum output level is achieved and turns on if the output level dropped below optimum’ (reference: Walsh‚ 2010)For example

Homeostatic Mechanisms Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state‚ while the world around it is changing constantly. There are many steps in the process of homeostasis. First‚ there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center‚ which decides the response. The information entering into
