Recommended: Effect on heart rate from exercise

The first compensatory mechanism is tachycardia and increased contractility that is caused by the activation of the sympathetic nervous system. This increase in heart rate and strength of contraction improves cardiac output and help maintain blood pressure. However, when the heart is beating to rapidly, blood is being pumped less efficiently. Similar because the heart is beating faster and harder, the myocardium requires more oxygen. If ischemia and hypoxia occur for a prolong period of time a myocardial infarction will

    It increases during physical exercise to deliver extra oxygen to the tissues and to take away excess carbon dioxide. As mentioned at rest, the heart beats around 75 beats per minute but during exercise this could exceed to 200 times per minute. The SAN controls the heart rate. The rate increases or decreases when it receives information by two autonomic nerves that link the SAN and the cardiovascular centre in the medulla of the brain. The sympathetic or accelerator nerve speeds up the heart. The synapses at the end of this nerve secretes noradrenaline. A parasympathetic or decelerator nerve, a branch of the vagus nerve slows down the heart and the synapses at the end of this nerve secretes

  • Pulse Wave Analysis Essay

    1900 Words  | 4 Pages

    O’Rourke [13] describes the pulse wave shape as: “A sharp upstroke, straight rise to the first systolic peak, and near-exponential pressure decay in the late diastole.” Arteries are compliant structures, which buffer the pressure change resulting from the pumping action of the heart. The arteries function by expanding and absorbing energy during systole (contraction of the cardiac muscle) and release this energy by recoiling during diastole (relaxation of the cardiac muscle). This function produces a smooth pulse wave comprising a sharp rise and gradual decay of the wave as seen in Figure 5. As the arteries age, they become less compliant and do not buffer the pressure change to the full extent. This results in an increase in systolic pressure and a decrease in diastolic pressure.

    The blood circulates through coronary arteries and then to smaller vessels into cardiac muscle (myocardium). The blood flow is influenced by aortic pressure, which increases in systole, and the pumping activity of the ventricles. When the ventricle contracts, in systole, the coronary vessels are compressed by the contracted myocardium and partly blocked by the open aortic valve therefore the blood flow through the myocardium stops.

  • Therapuetic Cloning

    Children grow up watching movies such as Star Wars as well as Gattaca that contain the idea of cloning which usually depicts that society is on the brink of war or something awful is in the midsts but, with todays technology the sci-fi nature of cloning is actually possible. The science of cloning obligates the scientific community to boil the subject down into the basic category of morality pertaining towards cloning both humans as well as animals. While therapeutic cloning does have its moral disagreements towards the use of using the stem cells of humans to medically benefit those with “incomplete” sets of DNA, the benefits of therapeutic cloning outweigh the disagreements indubitably due to the fact that it extends the quality of life for humans.

    Sympathetic pathways change nerve activity during times of stress, exercise, low blood glucose levels, excitement or fear, due to the flight or fight response. These changes can have an effect on homeostasis by increasing heart rate, increasing blood flow, dilating pupils, sweating, releasing glycogen, increasing oxygen intake and diverting blood flow away from the gastrointestinal tract.

    Hypothetically speaking, if patients asked their neurologists to explain what the nervous system is, how would typical neurologists respond to such a question? For the most part, patients ' question on what is the nervous system maybe a simple question for neurologists. In this instance, neurologists possibly explain to patients that the nervous System serves as a communication network that operates and coordinates the body 's activities. Operating and coordinating the body 's activities includes the nervous system to monitor thoughts, learning processes, body temperature, and altering the heart rate-- To name a few of the nervous system 's responsibilities. During the topic of discussion on the nervous system, patients asked their neurologists

  • The Heart

    1796 Words  | 4 Pages

    The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...

    Our arteries and veins are like hoses, they normally have a nice clean flow, but sometimes our blood pressure can be raised when bad things happen to them. Arteries can get clogged, and that happening is much like sticking your finger at the head of the hose to make the water squirt farther, the same amount of liquid has to get through but now with a smaller hole, so it has to go faster (Tamarkin Ph.D., 2011). Blood pressure is always faster right at the end of a ventricular systole, because the blood receives a large push from the contraction and that speeds up all of the blood in the body for a little bit. The blood pressure is also determined by how fast the heart has to beat to get the blood to the body, so higher blood pressure normally occurs when one is doing a lot of physical activity, is angry, or is under stress. The pulse we feel when we feel our wrist or neck is a surge of blood coming from our heart, so when our pulse is faster than that means our blood pressure has risen (Cordova, et al.,

  • Neuroplasticity Essay

    1133 Words  | 3 Pages

    As the human body goes through different experiences, the brain grows, develops, and changes according to the environmental situations it has been exposed to. Some of these factors include drugs, stress, hormones, diets, and sensory stimuli. [1] Neuroplasticity can be defined as the ability of the nervous system to respond to natural and abnormal stimuli experienced by the human body. The nervous system then reorganizes the brain’s structure and changes some of its function to theoretically repair itself by forming new neurons. [2] Neuroplasticity can occur during and in response to many different situations that occur throughout life. Some examples of these situations are learning, diseases, and going through therapy after an injury.

    Among various types of organ systems, the nervous system is one of the most important one in human body. It is responsible for producing, controlling and guiding our thoughts and responses to the world around us according to James W. Pennebaker (2012). During embryological development, the cells that form nervous system are incredibly specialised and work complexly than the cells that form skin or other body parts. Neurosecretory cells are one of the examples of specialised nervous system cells that produce neurosecretions. Neurosecretions are hormones which carry information from sensor cells to target cells and they can be released directly into the bloodstream according to Rene Fester Kratz, Donna Rae Siegfried (2010). The nervous system consists of two main parts: central nervous system (CNS) and peripheral nervous system (PNS) where CNS consists of the brain and spinal cord whereas PNS consists of ganglia and nerves which connect CNS to different parts of the body. The main function of the nervous system is to coordinate the voluntary and involuntary actions of the human body and transmit signals between different parts of the body.

    The nervous is considered to be the master controlling the systems of the body. The way it does this is to communicate through nervous impulse which is very rapid and very specific. The nervous system consist of the peripheral nervous system (PNS) and central nervous system (CNS). The peripheral nervous system consists of the cranial nervous, spinal nerves and ganglia. The peripheral nervous system can also be broking down into two categories which are somatic nervous system and parasympathetic system. On the other hand the central nervous system includes the brain and spinal cord. (fleming-Mcphillips, 2011)

    The human nervous system is composed of many different parts and performs many different functions. It is said to be the “body’s electrical wiring.” (Zimmerman) The nervous system itself is capable of collecting information, processing it, and then responding to the collected information where it then sends it to the appropriate part of the body to perform bodily functions. (Miller and Levine) The nervous system, as hinted in the name, is composed of many different nerves which are cylindrical bundles of fibers. These nerves start at the brain and proceed to branch down throughout the body. (Zimmerman) The human nervous system is made up of two main zones; The Central Nervous System and The Peripheral Nervous System. These two main categories are interdependent and work together to maintain homeostasis internally and externally. (Kinser)
