Why do Mammals with a high rate of respiration need to have a high heart rate?

To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues, this increases the heart rate it also increasing the blood flow to the tissues.

What disease that people suffer from make it twice as likely to have a stroke or heart attack?
the answer is high cholesterol because high cholesterol lowers your blood sugars which your brain and heart need, increasing the risk of heart attack or stroke.
What is the hearts role in maintaining homeostasis?
The heart pumps blood to all of your body. The blood contains oxygen and brings oxygen to all of your cells. The blood also takes carbon dioxide out of your cells and comes out when you exhale. Your cells need oxygen for energy, or cellular respiration. Cellular respiration allows your cells to function normally, maintaining homeostasis. Theorhetically, if the cells could get oxygen by themselves, without the help of blood, we wouldn't need a heart.
Why do birds need a four chambered heart?
A four-chambered heart prevents oxygen-rich blood from mixing with oxygen-poor blood and therefore ensures more efficient circulation than a three-chambered heart. Efficient circulation of blood is necessary for an animal with high metabolic needs. Birds have high energy requirements because they are warm-blooded and move mostly by flying.
When your pulse rate is high after exercise does that mean you lose calories?
Your heart rate will raise if you move off the sofa so would really need to know how high and for how long the heart rate is raised. I think you mean burn calories
What happens if you only have 2 heart chambers?
If your heart had only two chambers then oxygen-rich blood would be diluted by oxygen-poor blood and your body would not get oxygen as efficiently as it does. Efficient circulation is necessary for mammals such as humans to maintain a high metabolic rate.
Why do mammals with high respiration need to have a high heart rate?
The answer is quite simple. To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues. Increasing heart rate is one means of increasing the blood flow to the tissues. The other means in increasing the amount of blood that is from the left ventricle with each contraction.
Why does a person need to be kept in artificial respiration permanently?
blood flow to the heart
Does cellular respiration maintain the high metabolic rate in animals?
High metabolic rate need a lot of energy. So this is supplied by respiration
Are mammals aerobic organisms?
Yes. An aerobic organism is an organism that can grow and survive in the presence of oxygen. Mammals need oxygen to have cellular respiration, so they are obligate aerobes.
Do whales and dophins have gills for respiration explain?
Fish use gills, but whales and dolphins are mammals. They need to surface to take a breath of air periodically.
How do the chambers of the heart help in process of respiration?
The chambers of the heart need oxygen,and oxygen is part of the respiratory system which if the respiratory is gone,the heart will not receive oxygen and wouldn't pump blood this is my opinion by:jitiy
Why does a mammal need more oxygen than a reptile of the same size?
Yes, mammals have a 4chambered heart, while reptiles only have a 3chambered heart.
Does respiration always need oxygen?
No it does not as it can also respire anaerobicallyOxygen is needed for aerobic respiration only.Anaerobic respiration does not need
What cells need more respiration?
Cells that need more respiration typically include those that are highly active and require lots of energy. Examples of these cells include: Cells in muscle tissue Brain cells Cells in the heart Cells in the lining of the small intestineThese cells require more respiration in order to produce the energy they need to perform their intended functions.
Why does heart rate and respiration go up with exercise?
The more you exercise - the more oxygen your body's muscles need. In order for your heart to supply more oxygen - it must beat faster.
Is chlorophyll needed in cellular respiration?
no. humans respire and they do not have chlorophyll. Respiration is the process of releasing energy from food. To do thi you need to have glucose (from the food) and oxygen. Chlorophyll comes into it because plants need to conduct photosynthesis to get glucose. The chlorophyll is needed for this process to happen.
Why is external respiration vital to cellular respiration?
Cellular respiration need oxygen. This oxygen is supplied by external respiration
