Introduction

Theses labs were designed to show how our heart rates and pulses change depending on how much energy you are using. If you are exercising, then your heart rate will increase but once you are at a normal pace your heart rate and pressure will decrease. The energy exerted causes the respiratory rates to change, and will keep increasing as the breathing gets heavier. 
In the first lab, the objectives are to obtain graphical representation of heart rate and blood pressure, compare heart rate and blood pressure before and after exposure to cold stimulus. It is also to observe an example of sympathetic nervous system activation ("fight or flight response"). When the levels fluctuate, it stimulates the senses therefore pushing the body one direction or another. After the immersion, it took about 15 seconds fro the heart rate to reach its maximum value.
The objectives of the second lab are to obtain graphic representation of heart rate and blood pressure, determine the effect of exercise on heart rate, and systolic, diastolic and mean arterial pressures. It also uses blood pressure readings and pulse to infer changes in cardiac output and peripheral vascular resistance with exercise and correlate the fitness level of individuals with amount of daily exercise. The pulse pressure is the difference between systolic pressure and diastolic pressure. The systolic pressure increased while the diastolic decreased. 
The third lab's objectives are to obtain graphical representation of the electrical activity of the heart over a period of time, to learn to recognize the different wave forms seen in an EKG, and associate these wave forms with activity of the heart. It's also to determine the heart rate by determining the rate of individual wave forms in the EKG and to compare wave forms generated by alternate EKG lead placements. Certain things can be passed on by the parents to the children. 
In the fourth lab, the objectives are to obtain graphical representation of lung capacities and volumes, compare lung volumes between males and females, and to correlate lung volumes with clinical conditions. Measurement of lung volumes provides a tool for understanding normal functions of the lungs as well as disease states. The breathing cycle is initiated by expansion of the chest. The males IRV and ERV are higher than females. If a foreign object was inhaled and it obstructed my right main stern then you would expect the tidal volume to be half of the original total. 
The fifth lab's objectives are to obtain graphical representation of normal tidal volume, to compare tidal volumes generated by various physiologic challenges, and to correlate your findings with real-life situations. The respiratory cycle of inspiration and expiration is controlled by complex mechanisms involving neurons in the cerebral cortex, brain stem, and peripheral nervous system, as well as chemicals and pressure. The greatest change in the respiratory rate occurred during the rapid breathing. 
In conclusion, in these labs we figured out the respiratory rates, the increase or decrease of the heart rate depending on the energy we are using. During exercise we know that the respiratory rate will increase because it is doing more work. We also test the differences in the respiratory rates between males and females.
