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

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

The purpose of this lab was to hypothesize about membrane traffic in lab‚ explain the differences between the solutions hypertonic‚ hypotonic‚ and isotonic and how they respond using the understanding of the cell membrane structure‚ types of transport mechanisms such as active‚ passive‚ diffusion‚ osmosis‚ and explain the movement of particles moving across the cell membrane. In this lab was divided into two parts. The first part was varying the concentration and the second part was varying the temperature
