cell membrane’ potassium channels. These two actions result in a reduction in the cardiac muscle contraction. Another chemical known as epinephrine has the opposite effect on cardiac muscle. In the wall of the right atrium‚ there is a cluster of cells called the sinoatrial node that sets the rate for which all cardiac muscle contracts. Hormones‚ such as epinephrine‚ within the body can influence the sinoatrial node and cause the heart rate to increase (Campbell and Reese‚ 2009). Hypothesis The Effect

Chemical and Environmental Effects on the Heart Introduction The heart is the centerpiece of the circulatory system‚ its muscular contractions allow for the timely delivery of essential gases and nutrients to virtually all cells of the body. The pressure created by the heart also plays a vital role in eliminating wastes through organs such as the kidney‚ thus the heart delivers and helps maintain nutrient and waste composition throughout the body. The heart‚ like all muscle cells‚ releases ionic

o A key landmark when performing an axillary block is the identification of the axillary arterial pulse as well as the Coracobrachialis and pectoralis major muscle. o In supine position with the patient’s head turned away from the intended injection site‚ the desired arm is abducted 90° angle at the elbow joint. While standing at the upper arm‚ feel for the axillary artery (lateral to the pectoralis muscle) and draw a line along it from the mid-axilla to the lower axilla. This is helpful orientation

A compound known as epinephrine in adrenaline injection was first addressed for the treatment of asthma in 1903 by Bullowa & Kaplan. Few years later its usage soon came to an end when it had been found to cause unwanted effects on cardiovascular system.

The effects toxins such as caffeine‚ nicotine‚ epinephrine‚ ethanol and salt have on the Daphnia magna’s heart rate Results The effect the various drugs caffeine‚ nicotine and epinephrine had on the Daphnia magna is displayed in Figure 1. After three sample trials were taken there was an average of 180 beats/min-1 ± 6.928 taken under normal conditions. The addition of caffeine caused an increase in the average heartbeat to change to 192 beats/min-1 ± 9.165 in the Daphnia magna tested. When testing
