Not only did Stephen Hales pioneer the study of plant physiology, then he contributed to the first major account of blood pressure, and the invention of a machine for ventilating buildings. To formulate the results vital for his implications, he carefully measured the blood pressure of three horses which produced the first recorded estimates of blood pressure, as stated in the biography. In addition to, studying the pulse rates from various animals and measured the heart capacity to pump blood through the pulmonary veins, thus experimenting
