Biology Topic 1 MAINTAINING A BALANCE What is this topic about? To keep it as simple as possible‚ (K.I.S.S.) this topic involves the study of: 1. ENZYMES & HOMEOSTASIS 2. TEMPERATURE REGULATION 3. INTERNAL TRANSPORT SYSTEMS 4. EXCRETION & WATER BALANCE but first‚ an introduction... Living Things are Made of Cells Homeostasis All living things are composed of microscopic units called cells. You learned in a previous topic about the structure of a cell and the functions of the

Homeostasis A state of balance in the body Whoa Homeostasis “the tendency of a system‚ esp. the physiological system of higher animals‚ to maintain internal stability‚ owing to the coordinated response of its parts to any situation or stimulus tending to disturb its normal condition or function” - Dictionary.com Unabridged (v 1.1) “The ability or tendency of an organism or a cell to maintain internal equilibrium by adjusting its physiological processes.” - American Heritage Stedman’s Medical

Hypertension My name is Jennifer‚ and I am the education nurse here at ITT Internal Medicine. Your doctor asked me to explain to you your diagnosis of hypertension. I will go over what hypertension is‚ how your cardiovascular system works and maintains homeostasis‚ how the rest of your body could be affected by hypertension‚ and what you can do to lower your blood pressure. Hypertension is a chronic medical condition where the pressure of blood in the arteries is elevated. Blood pressure is

The majority of women have minimal complications with natural child birth but to some the process may be life threatening. Past statistics have shown a high rate of child birth mortality. Today‚ this rate has decreased with the advancement of the medical field. However‚ women all over the world are still facing different kinds of complications

DIET AND HYPERTENSION Hypertension or High Blood Pressure‚ as it is commonly called‚ is a condition in which the blood pressure in the arteries is chronically elevated. With each heart beat‚ heart pumps blood through the arteries to the body. Blood pressure is the pressure or force with which blood is pushed against the walls of the blood vessels. If the pressure is too high‚ the heart has to pump harder which in turn can damage the body organ and cause illnesses like stroke‚ heart attack‚ heart

wonder why the body shivers when it gets cold? Homeostasis keeps body conditions steady and constant. So‚ this means that when the body shivers‚ that is homeostasis taking place trying to keep your body temperature at a constant degree. Homeostasis maintains normality in the body in many different ways. Some examples include osmoregulation‚ thermoregulation‚ chemical regulation‚ and behavioral homeostasis. While homeostasis controls these processes‚ homeostasis must also go through a separate process of

Homeostasis‚ in general‚ the sleep-wake cycle is regulated by two separate biological mechanisms in the body which interact together and balance each other. Studies say that high levels of adenosine leads to sleepiness. According to the two process model of sleep regulation the timing and structure of sleep are determined by the interaction of a homeostatic and a circadian process. The original qualitative model was elaborated to quantitative versions that included the ultradian dynamics of sleep

clinical in the female medical ward‚ my patient was a sixty-six-year-old woman who was diagnosed with four different medical conditions; Uncontrolled hypertension‚ left bundle branch block (LBBB) which is a cardiac conduction abnormality seen on the electrocardiogram (ECG). In this condition‚ activation of the left ventricle of the heart is delayed‚ which causes the left ventricle to contract later than the right ventricle. Venous insufficient which is a condition where the flow of blood through the veins

Lab 1: Homeostasis Background Information: Homeostasis is the existence of a stable environment in the body for survival. This process is always regulating bodily functions in order to keep the body in optimal condition. When conditions change a receptor senses and sends a message to a control center. The control center processes the information and sends an appropriate command to effectors. These effectors will respond to the command which will stimulate a positive or negative response. A positive
