Why can blood flow freely through arteries?
Arteries are blood vessels taking the blood away from the heart. the heart is a very powerful muscle so blood is ejected out at a high velocity and with high pressure.
Does high humidity effect congestive heart failure in elderly?
Yes. High humidity along with high temperatures puts stress on the cardiovascular system.
U have a heart rate of 102 per minute is this dangerous and what can be done to reduce it so that not too much strain is on the heart muscle?
>100 is high. >140 is dangerous. A high heart rate generally means your out of shape. Go see a doc, they'll do an UltraSound to determine if your heart works fine or not.
The left ventricle is hyperdynamic what does that mean?
It means enlargement of the left ventricle of the heart. This is due to excess work done by the heart as in high blood pressure, damage to the heart muscle after heart attack, valvular disease, respiratory disease putting extra strain to the heart.
What is the function of the blood vessels on the outer wall of the heart?
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
What substance in muscle seems able to store oxygen temporarily?
Myoglobin is the substance in muscle that can temporarily store oxygen. It is a protein that has a high affinity for oxygen, allowing it to capture and hold oxygen until it is needed for muscle activity.
What substance in muscle stores oxygen temporarily?
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
Can the body survive without myoglobin?
I suppose it cannot. Myoglobin is related to hemoglobin, but has a different oxygen affinity. It is present in your muscles, where it provides oxygen for aerobe glycolysis. Without myoglobin, your muscles would have to resort to anaerobic processing at all times, even at rest, which is less efficient and creates more harmful products that have to be neutralized. Not only would this place a high demand on your liver, it would also make the environment of your largest, most active muscle - your heart. The damage this would do to your heart would eventually lead to heart failure.
How can the oxygen store in myoglobin be replaced after use?
The oxygen store in myoglobin can be replenished by diffusion from the bloodstream, where oxygen is carried by hemoglobin. When myoglobin releases oxygen to the muscle cells for energy production, it becomes deoxygenated, creating a concentration gradient that drives the diffusion of oxygen back into myoglobin. This process allows myoglobin to continuously store and release oxygen as needed by the muscle cells.
The function of myoglobin is to?
The function of myoglobin is to store and transport oxygen within muscle cells. It has a higher affinity for oxygen than hemoglobin, allowing it to efficiently capture oxygen from the bloodstream and release it as needed during muscle activity.
Does tuna cause nightmares?
It's possible.The high level of Myoglobin in tuna muscle tissue can cause headaches, nightmares and anxiety in some people.
Why myoglobin has high affinity to oxygen?
Myoglobin has a high affinity for oxygen due to the heme group present within its structure, which can form strong bonds with oxygen molecules. The heme group has a distal histidine residue that stabilizes the bound oxygen molecule, contributing to the high affinity of myoglobin for oxygen. Additionally, myoglobin has a hydrophobic pocket that further enhances its ability to bind oxygen tightly.
What is a fast fiber?
A Fast Oxidative Fiber is a type of muscle fiber with many mitochondria and capillaries. This type has a high myoglobin content. This type of muscle tires more quickly than the slow oxidative fibers and is an intermediate sized muscle. This muscle is good for sprinting and other short, fast-paced activities.
What is the heathiest fruit in the world?
Apples - high in fiber, lowering the risk of heart disease.Bananas - also high in fiber. Benefits muscle function and heart health.
Can high blood pressure result in less oxygen reaching heart muscle?
Yes.
What kind of human cell would contain a high proportion of mitochondria?
Heart muscle
Which organelle would you expect to be the most highly concentrated in heart muscle cells?
Mitochondria as the heart requires a lot of energy.
