Explanation:
Definition of pulse= Pressure wave originates in the aorta due to ejection of blood from left ventricle during systole.
DESCRIPTION=
1]A pulse generated due to the rhythmic expansion and contraction of the arteries that occurs as the heart pumps blood throughout the body.
2]It is typically measured by feeling the pulse at specific points on the body, such as the wrist or neck, and counting the number of beats that occur in a set amount of time.
3]The pulse rate is usually expressed in beats per minute (bpm) and can vary depending on factors such as age, physical activity, and overall health.
4] A healthy adult has normal resting pulse rate of 60 to 100 bpm.
Step 2/3
Explanation:
Importance of pulse identification
The identification of the pulse is important for following reasons=
1) Monitoring Heart Health: The pulse rate is an essential indicator of heart health. By measuring the pulse rate, medical professionals can identify irregularities in the heartbeat, which can be a sign of underlying heart conditions or other health problems.
2]Diagnosing Medical Conditions: Identifying the pulse is also important in diagnosing medical conditions such as arrhythmias, which are irregular heartbeats, and other cardiovascular diseases. It can also help in monitoring conditions like hypertension (high blood pressure) and hypotension (low blood pressure).
3]Evaluating Physical Fitness: Measuring the pulse before, during, and after exercise can provide valuable information about a person’s physical fitness level. It can help to determine the appropriate level of exercise intensity and also track progress over time.
4]Administering Medications: In some cases, the pulse rate is used to monitor the effects of medications on the body. Certain medications can affect the pulse rate, so monitoring it is important to ensure that the medication is having the desired effect.

Explanation:
Basic anatomy and physiology of the circulatory system
ANATOMY OF CIRCULATORY SYSTEM=
1]The circulatory system is responsible for transporting oxygen, nutrients, and other essential substances throughout the body. It consists of the heart, blood vessels, and blood.
2]The heart is a muscular organ that pumps blood throughout the body. It has four chambers: the right atrium, left atrium, right ventricle, and left ventricle.
3]The atria receive blood from the body and lungs, while the ventricles pump blood out of the heart to the lungs and body, respectively.
4]Right atrium receives deoxygenated blood from superior vena cava and inferior vena cava
5] Right atrium pumps blood into right ventricle
6] Right ventricle pumps the deoxygenated blood into pulmonary artery which delivers the blood to lungs where it gets oxygenated
7]Left atrium receives oxygenated blood from lungs through the pulmonary veins.
6]Left ventricle receives blod from left atrium and pumps oxygenated blood to aorta which delivers oxygenated blood to the whole body.
PHYSIOLOGY OF CIRCULATORY SYSTEM=
1]Blood vessels are tubular structures that carry blood throughout the body. There are three types of blood vessels: arteries, veins, and capillaries.
2]Arteries carry oxygenated blood away from the heart to the body’s tissues, while veins carry deoxygenated blood back to the heart.
3]Capillaries are the smallest blood vessels and are responsible for exchanging oxygen, nutrients, and waste products between the blood and body tissues.
4]Blood is a fluid that circulates throughout the body within blood vessels. It is composed of several components, including red blood cells, white blood cells, and platelets, suspended in a liquid called plasma.
5)Red blood cells are responsible for carrying oxygen to the body’s tissues, while white blood cells help to fight off infections and platelets help with blood clotting.
6]The circulatory system works by pumping blood through the heart and blood vessels to deliver oxygen and nutrients to the body’s tissues and organs. 7]Deoxygenated blood returns to the heart to be pumped to the lungs for oxygenation, while oxygenated blood is sent out to the body’s tissues to provide energy and nourishment. This continuous cycle is what allows the body to function properly and maintain overall health.

Final answer
1]Pulse is a pressure wave generated in the aorta due to contraction of left ventricle in the systole.
2] Pulse is generated due to rhythmic expansion and contraction of arteries as heart pumps blood throughout the body.
