When it is cold outside and the temperature drops‚ your body thermo receptors detect the drop and send signals to the hypothalamus. Neurons also send signals to smooth the walls of the blood vessels to make them contract‚ which creates a narrowing in the blood vessel also known as “vasoconstriction”. What vasoconstriction

Homeostasis A condition in which the internal environment of the body remains relatively constant despite changes in the external environment. Examples would be the maintenance of body temperature and levels of glucose in the blood Homeostatic mechanisms are designed to reestablish homeostasis when there is an imbalance. The Home Heating System 1. When the temperature of a room decreases below a set point‚ the thermostat electrically starts the furnace. 2. As the temperature of the room rises to

Hypertension Sha’mes Lashawn Handford Moss Point High School November 16‚ 2012 Abstract Hypertension is the most chronic medical condition that adults have. This disease affects many organs of the body including the heart‚ eyes‚ and kidney. Hypertension can increase with age‚ weight‚ and inheritance. Generally‚ the hypertensive population is increasing but physicians are working on various treatments to prevent and control this disease. Prescription drugs in the United States are
Premium Hypertension
Hypertension (HTN) or high blood pressure‚ sometimes called arterial hypertension‚ is a chronic medical condition in which the blood pressure in the arteries is elevated.[1] This requires the heart to work harder than normal to circulate blood through the blood vessels. Blood pressure is summarised by two measurements‚ systolic and diastolic‚ which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole). Normal blood pressure at rest is within the range of

HYPERTENSION What is hypertension? Hypertension‚ also known as high blood pressure‚ is a common condition that occurs when the pressure of the blood in your artery walls is so high; it starts to complicate your health. Your blood pressure is based on how much the heart pumps and the amount of resistance to the blood flowing in the arteries. The harder it pumps‚ the more constricted the arteries are‚ the higher the blood pressure reads. High blood pressure can be in a person for years and go
Premium Hypertension Blood pressure
Hypertension Also known as high blood presion. Hypertension can damage the arteries‚ heart‚ brain‚ kidneys and eyes. Hypertension has no symptom‚ that’s why it’s called a “silent killer”. People with uncontrolled hypertension may have drowsiness‚ confusion‚ headache‚ nausea‚ loss of vision and difficult breathing. Primary hypertension cause is unknown; it tends to develop gradually over the years. Secondary hypertension can be cause for various conditions. Kidney problems‚ medications like control
Premium Hypertension Stroke
Hypertension‚ also referred to as high blood pressure‚ is a condition in which the arteries have persistently elevated blood pressure. Every time the human heart beats‚ it pumps blood to the whole body through the arteries. Blood pressure is the force of blood pushing up against the blood vessel walls. The higher the pressure the harder the heart has to pump. Hypertension can lead to damaged organs‚ as well as several illnesses‚ such as renal failure (kidney failure)‚ aneurysm‚ heart failure

Mr. O = 63-year old male patient with Hypertension Eric = 13-year old middle school honors student with Diabetes Hello Mr. O‚ I am Ashley‚ the Nurse Educator and I am here to explain your recent diagnoses‚ Hypertension to you. Hypertension means to have high blood pressure. A considerably healthy blood pressure would be between 110/70 to 120/80. A blood pressure 140/90 and above is considered a high blood pressure which causes hypertension. High blood pressure is when the force of blood pushing

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to

The many processes by which the body controls its internal environment are collectively called homeostasis. The complementary activity of major body systems maintains homeostasis. Homeostasis is the maintenance of a constant internal environment. It is involved in many bodily functions‚ such as keeping the body’s internal environment constant much like the thermostat of a central heating system. Homeostasis keeps the body’s temperature at a certain level and it keeps the pH of the body at a certain
