REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

TUTORIAL 4 – DISCRETE DISTRIBUTIONS Question 1 An experiment consists of picking a card at random from a standard deck of cards and replacing it. If this experiment is performed 12 times‚ what is the probability that you get: (a) exactly 2 aces; (b) exactly 3 hearts; (c) more than 1 heart. Solution Let n = 12‚ the no of experiments. (a) Let p = probability of obtaining an ace in an experiment of picking a card at random from a standard deck of cards; and = 4/52 = 1/13

Anatomy and Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However‚ it is the respiratory

Endocrine system Endocrinology is the study of chemical communication systems that provide the means to control a huge number of physiologic processes. Like other communication networks‚ endocrine systems contain transmitters‚ signals and receivers that are called‚ respectively‚ hormone producing cells‚ hormones and receptors. The first step in understanding endocrinology is to explore the meaning of such terms as hormone‚ receptor and target cell‚ and to obtain an understanding of how chemical

When we exercise circulatory system‚ respiratory system and muscles are affected. Short term effects are immediate and long term refers to our adaptation to exercise. After an intense exercise we are still breathing heavily‚ that is due to our internal respiration taking in more oxygen or cellular respiration (where the cells converts the food into energy or releases the molecules of Carbon‚ Hydrogen‚ Oxygen and Nitrogen which make up our food and are stored to higher cells known as ATP or Adenosine

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

ANATOMY AND PHYSIOLOGY OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the
