Cardiovascular and respiratory systems respond to exercise in several key ways:
1. The heart rate increases before and during exercise to pump more blood and oxygen to working muscles. Blood pressure also increases to circulate blood effectively.
2. Breathing rate and depth increase to supply more oxygen to working muscles and remove excess carbon dioxide. Both neural and chemical factors stimulate faster, deeper breathing.
3. The lungs take in more air per breath (increased tidal volume) to meet the body's higher oxygen needs during exercise beyond just breathing faster. Blood flow is also altered to match regional demands through vasodilation and vasoconstriction of blood vessels.

Respiration is defined as the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
The physiological definition of respiration should not be confused with the biochemical definition of respiration, which refers to cellular respiration: the metabolic process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy). Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment.
Dear all,
This ppt includes the acute and chronic effect of exercise on different body system which includes musculoskeletal systems, cardiovascular systems, respiratory system, endocrive system, psychological effects etc. I hope this is helpful for you.
Thank you
A warm up (as it relates to physical activity and exercise) is any activity, either physical or mental, that helps to prepare an individual for the demands of their chosen sport or exercise.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

1. Michael Masher Assessment Activity 2 – That’s What Friends Are For! Unit 2: The Physiology of Fitness P2 – Describe the Cardiovascular and Respiratory Systems Responses to Acute Exercise
2. Cardiovascular Heart Rate Anticipatory Response: Nerves that directly supply your heart and chemicals in your blood can rapidly alter your heart rate, before the start of the exercise your heart rate usually increases above resting levels. Activity Response: At the start or just before the exercise, nerve centres in your brain detect cardiovascular activity. This results in adjustments that increase the rate and pumping strength of your heart. At the same time the regional blood flow is altered in proportion to the intensity of the activity undertaken. Increased Blood Pressure: Blood pressure is the pressure of blood against the walls of your arteries and results from 2 forces. During exercise, despite both cardiac output and blood pressure increases , these mechanisms act to restrict the blood pressure rise and eventually bring it down. Vasodilation & Vasoconstriction: The primary function of vasodilation is to increase blood flow in the body to tissues that need it most. Vasoconstriction is the narrowing of the blood vessels resulting from contracting of the muscular wall of the vessels, which is the opposite of vasodilation.
3. Respiratory Increase in Breathing Rate (Neural and Chemical Control): Exercise results in an increase in the rate and depth of breathing. During exercise your muscles demand more oxygen and the corresponding increase in carbon dioxide production stimulates faster and deeper breathing. A minor rise in breathing rate prior to exercise is known as an anticipatory rise. After several minutes of aerobic exercise, breathing continues to rise, though at a slower rate, and it levels off if the exercise intensity remains constant. Neural involves the brain and nervous system, for example, you are affecting your rate of breathing by use of your brain. Chemical is of course involuntary effect on breathing of a chemical entering the system, such as an anesthetic which slows the breathing and renders you unconscious. It would imply that the brain is not able to override a chemical control or influence. Increased Tidal Volume: Tidal volume is the volume of air you breathe in a single breath. Exercise causes an increase in tidal volume because your requirements for oxygen go up. This increase is measured in different ways depending on when it occurs during your exercise. An increase in tidal volume is necessary to effectively meet your body's increased oxygen requirements, as an increase in your rate of respiration alone is not sufficient. Tidal volume is approximately 500 ml of air per breath. However, changes in air requirements, such as those that occur during exercise, and changes in your lungs' ability to expand and contract.
