Cardiovascular Health

Yes. To much intake can be harmfull but elevated potassium levels in the body can cause irregular heart beats, cardiac arrhythmia, tachycardia and even heart attack. It depends on the kidney function as well. Excess boday potassium in the body is passed out through urine. But kidney failure or a underfunctioning kidney can cause excess potassium to bould up and cause heart attack. Elevated potassium levels is called Hyperkalemia and low potassium levels are called Hyporkalemia. Both are dangerous.

The time it takes to bleed out from a cut in the brachial or femoral arteries or the jugular vein can vary depending on the individual's health, the severity of the injury, and how quickly medical help is received. In general, a severe arterial bleed can lead to unconsciousness and death within minutes if left untreated. It is critical to seek immediate medical attention to control bleeding and prevent further complications.

Yes, red blood cells can die. They have a lifespan of about 120 days and are then broken down and recycled by the body's immune system.

You should see a cardiovascular doctor if you have risk factors for heart disease, such as high blood pressure, high cholesterol, or a family history of heart problems. Additionally, if you experience symptoms like chest pain, shortness of breath, or palpitations, it's important to consult a cardiovascular doctor for proper evaluation and management.

i have pain in my leg for about ayear now. the pain i worse at night specially during cold seasons so what do you thing is cause and can to releaf this pain

Try laying on your back while pulling your toes towards your head as far as you can without causing severe pain. hold it for 10-15 seconds and repeat each leg three times. Also pull your knee towards your stomach while laying down for the same durations. Sit-ups will also strengthen your stomach relieving some pressure on your lower back, which is likely causing the pain. If it goes down the back of your leg this might help after a week or so of stretches. I have pain in my leg from a herniated disc in my back; it travels down the back of myt leg and switches from side to side. Other than that strong pain killers that are not a good idea to use and are very addictive.

Coronary perfusion rate, which is the amount of blood flowing to the heart muscle, is closely related to blood pressure. Higher blood pressure can increase coronary perfusion rate, delivering more oxygen and nutrients to the heart. However, extremely high blood pressure can strain the heart and lead to heart problems.

The cardiovascular system circulates oxygen-rich blood throughout the body, delivering nutrients and removing waste products. It also helps regulate body temperature and maintain pH balance. Additionally, it plays a crucial role in immune response and hormone transportation.

The cardiac reserve capacity is the difference between the rate at which the heart pumps blood and its maximum capacity for pumping blood a any given time. It's the potential capacity of the heart to function well beyond its basal level.

Angina is chest pain or discomfort that occurs when the heart muscle is not receiving enough oxygen-rich blood. It is typically caused by the narrowing of the coronary arteries due to a build-up of plaque, reducing blood flow to the heart. Angina can be triggered by physical exertion, stress, or other factors that increase the heart's demand for oxygen.

A normal ALT (alanine aminotransferase) level in a blood test is typically between 7 to 56 units per liter. However, reference ranges may vary slightly between different laboratories. It's important to interpret the result in the context of the individual's overall health and medical history.

External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

The hunter's reflex is a physiological condition whereby in cold weather the blood vessels in the forearm allow blood to flow to the hands thus keeping them warm and useful, rather than the normal response which is to withdraw blood from the extremities to protect the core.

I just thought to give a simple answer with my little knowledge of anatomy and physiology.Blood should have that much of warmth to keep all live parts in a constant manner. Like the water of this earth blood flows everywhere and should be so. Respiration is the result of breath not just air.The wave of breaths is the result of a big pressure burst occurred at birth.so all the systems there you see are the formations of energy variants of each level which contribute to each other to keep the energy transformation at a constant rate.

Arteries are generally located deeper in the skin to protect them from external injuries and to maintain a stable blood flow. This deeper location also helps to regulate the temperature of the blood within the arteries.

Common tumors found in the cardiovascular system include cardiac myxoma, angiosarcoma, and atrial septal defect. In the integumentary system, common tumors include basal cell carcinoma, squamous cell carcinoma, and melanoma.

Dietary cholesterol does not really affect triglyceride levels. If triglycerides are your main problem your best best is to eliminate sugar and white grain products from your diet, as simple carbohydrates are converted into triglycerides in the liver.

As I understand it, and very simplistically, I think it means that the bonding is easily reversible. In other words, the O2 is readily bound to haemoglobin but is also readily released depending on the partial saturation levels of Oxygen (PO2) that are encountered by the RBC. * In the pulmonary capillaries the PO2 is high and therefore the amount of O2 bound to Hb is also high (fully saturated). In the systemic capillaries the PO2 is low and hence the O2 dissociates with the Hb and diffuses into the tissue cells. (The Hb is then said to be partially saturated). Although PO2 is the major factor in the binding of O2 to Hb, other factors also effect this process. * Acidity: Lactic acid and carbonic acid generated during exercise lowers the pH of the blood which promotes the release of O2 from Hb. Hence the exercising tissues which require extra O2 help create a situation where more O2 is available. * PCO2 effects the transport and delivery of O2. Increased metabolic activity of the tissue cells produces more CO2 as waste, which promotes release of O2 from Hb through an associated decrease in pH (see above point) and also as part of an O2/CO2 cycle. It goes something like this:

In the pulmonary capillaries, O2 diffuses from the alveolus into the RBC. It binds to Hb to create oxyhaemoglobin and H+ ions. Bicarbonate ions combine with the H+ ions to create carbonic acid which, under the influence of the enzyme carbonic anhydrase, dissociates into CO2 and water. The CO2 diffuses into the alveoli and is expelled by the lungs.

The RBC then travels in the blood to the systemic capillaries and CO2 diffuses from the tissues (as a waste product of tissue cell metabolism) into the RBC. A small percentage of the CO2 binds to the globin in Hb, forming carbaminohaemoglobin, this causes O2 to dissociate from the haem part of the Hb. The O2 then diffuses from the RBC into the tissue cells.

Most of the CO2, under the influence of the enzyme carbonic anhydrase, combines with H2O to become Carbonic acid which then dissociates into Bicarbonate ions (HCO3-) and H+ ions. The H+ ions promote the dissociation of O2 from the haemoglobin by taking the place of the O2 in the Hb molecule. * Increased temperature also has a minor effect of promoting the release of O2 from the Hb. Anatomy and physiology books such as "Anatomy and Physiology - From Science to Life" by Jenkins Kemnitz and Tortora is a fabulous resource for understanding the intricacies of this process.

The respiratory system works with the body to help our body function correctly. One of the things it does is it gives our cells/blood oxygen to take to the rest of our body.
the respiratory system affects the body by allowing you to obtain oxygen

The theory behind high altitude athletic training is that since there is less oxygen present in high altitudes, athletes must train their bodies to be able to handle less oxygen by producing more red blood cells to carry the necessary oxygen. Oxygen is also depleted in the blood and muscles through strenuous activity. Therefore, by training at a high altitude, an athlete can expect to perform better at a lower altitude.

Pulmonary Circulation is part of the Cardiovascular system in which it carries oxygen depleted blood away from the heart and to the lungs and returns oxygenated blood back to the heart. Deoxygenated blood exits the heart through the pulmonary arteries and enters the lungs and oxygenated blood comes back through pulmonary veins. The blood moves from right ventricle of the heart to the lungs back to the left atrium.

The thin-walled priming chamber pump of the heart. Each of the two atria lies above the ventricle, separated by a one-way atrioventricular valve. The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.

It's important to consult a healthcare professional to determine the cause of your symptoms. Chest discomfort and pain in the left shoulder could be indicative of various conditions, including musculoskeletal issues, gastrointestinal problems, or cardiovascular concerns. Seeking medical evaluation can help pinpoint the underlying cause and determine the appropriate treatment.

Cardiac muscle has what is known as intercalated disks. These connect heart muscle cells to each other, which allows an impulse (contraction) to move through the heart synchronously and therefore beat as it should.
