What effect does temperature have on rate of breathing?
When it gets colder what happens? Your body tries to keep itself at 98.6 F. This is called homeostasis or internal regulation. In order for that to happen, your body must pump blood faster through your veins to keep your extremities at 98.6F As your pulse increases, the need for oxygen also increases since your lungs transfer oxygen to the blood. This rule makes it almost impossible to hold your breath for long periods of time in cold water. Without breathing your body cannot transfer oxygen to your muscles. In the cold, this is exceptionally important so your cells dont die. If you jump into a cold pool, youll notice that youll inhale deeply and at a quick pace.
The inverse can be said about warmer temperatures. If you were in a jacuzzi, you might notice your breathing slowing down. This is why warm water is a traditional use for relaxation. Your muscles dont go cold, so there is less need to get high amounts of oxygen to them.
Here is a test: 1. put your hand in ice water for a minute and then try and move it afterwards. What did it feel like? 2. Put the same hand, after it has warmed back up, into warm water. bring it out and try and move it. what did it feel like?
When temperature increases, breath rate decreases and vice versa... Simple
How do you operate a rototiller?
To use a rototiller, first start it. Then move it out to the area to be tilled. Set the tines on the ground to be tilled and engage the tines. It should dig right in. On a self propelled rear tine tiller, all you have to do is follow along behind it keeping a downward pressure on the handles so that the tines stay in the soil. On a mid or front tine tiller that is not self propelled, you have to push the tiller forward and keeping a downward pressure on it so it digs in, but not too much pressure or will it dig it self into a hole. With all tillers, but paticulary smaller front or mid tine tillers, keep an eye out for rocks or sticks or roots or clay soil, this will cause the tiller to jump if it strikes it and it can be possible to lose control of it with smaller tillers. Sticks may tangle the tines in small tillers. Always keep your feet and hands away from the tines unless the engine is turned off.
Why does my 1994 Pontiac Sunbird die at stop signslights?
maybe its your alternator, if its giving off a weak enough charge, when you put the brake lights on, it drains too much power to run your engine. to check the alternator, start car, and remove the positive cable from your battery with some accesories running. if your car sputters, or stalls, just replace the alternator. hope this helps.
Which hormone is released by cardiac muscle in response to abnormal stretching of the heart walls?
ANP
How many chamber does a mallard duck heart have?
The bald eagle, a bird, has a four-chambered heart, as do all other birds and mammals.
Does your heart pump the blood that carries food to the bones and makes them strong?
Yes, your heart pumps the blood that carries nutrients to the bones. This is an important way that the circulatory and skeletal systems work together.
What is slightly enlarge heart?
The heart enlarges to compensate for conditions in the body that affect heart flow and functions of the heart. It would be more telling to know which side of the heart is enlarged or if the whole heart.
Does the left chambers carry blood without oxygen?
The right ventricle pumps unoxygenated blood to the lungs to acquire oxygens and release carbon dioxide. The blood is then returned to the heart via Pulmonary Veins to be pumped from the left ventricle to the tissues that need it in your body! :]
Why are the walls of the ventricles made of muscle?
The walls of your ventricles are made of smooth muscle because they need to be able to push the blood through your heart. There are valves that open and close to make the blood flow the correct way in the ventricles. The left ventricle has a thicker layer of smooth muscle because it needs to pump blood to the entire body while the right ventricle's smooth muscle doesn't need to be as thick because it is just pumping blood to the lungs which aren't very far away.
Part of the heart that has oxygenated blood passing through it?
The left part...the left auricle & left ventricle
What if your heart is 126 a minute what could happen?
120 beats per minute is the approximate maximum heart rate of a fit person during hard cardiovascular exercise. At that rate you can feel your heart pounding in you chest and feel flushed.
If your heart were to continuously pump blood at that rate you would soon suffer cardiac arrest.
When does the nervous system tells the body to decrease its heart rate?
When the heart rate is too high, e.g. after exercise when you start to rest.
Valves and blood vessels control the flow of blood through the heart. The aorta governs the functioning of these structures by being the main artery in the cardiac system.
Which of these correctly traces the path of blood from the left ventricle to the head?
left ventricle
What is a blood cloth in the vessels leading to the brain?
A blood clot in the vessels leading to the brain is a cerebrovascular accident (CVA), a stroke, or a cerebral thrombosis. Such a clot can block oxygen provision to the brain and cause permanent damage.
What causes clunking sounds after shifting into first gear and truck begins to move?
could be u-joints or a sloppy ring and pinion gear mating. The slack has got to be taken up somewhere. Without knowing the mils i would get under truck and wiggle up and down and side ways and twist by hand all the u-joints and look for wear even rust, that would be the cheapest fix
Why does your heart stop when your scared?
Your heart will feel like it has stopped because when something scares you, you will think about that for that second or two and your brain will have forgotten that it needs to send messages down to your heart to make it pump blood into your system. i think.....
Who needs an artificial heart valve?
An artificial heart valve is needed if your natural valve is leaking beyond a point that is causing the chambers (ventricles) to enlarge thus reducing blood flow through the lungs and creating increased pulmonary pressure. With a new valve the back pressure is eliminated and the heart becomes a much more effective pump.
