Does the rib expand during inhalation or exhalation?
The ribs expand during inhalation. This creates negative pressure on the lungs and draws air into them. During exhalation the rib cage gets smaller, compressing the lungs, in a sense, and forcing air out.
What is the name of the rib muscles that contribute to breathing?
Ribs are bones, but lungs contribute to breathing and they are a muscle organNo, your Lungs ARE NOT A MUSCLE. Your diaphragm is the main muscle in inhalation, which opens your lungs (works by creating a negative pressure in your lungs i.e. the pressure outside your chest cavity is more than the pressure in your lungs, causing air to enter your lungs).However, during forced inhalation and exhalation your intercostal muscles and rectus abdominus muslces play a part in exhalation (forcing air out). scalenes lift up your rib cage to allow maximum inhalation.
What is an abnormal result in allergy testing?
Presence of redness or swelling,especially over 5 mm (1/4 inch.indicates an allergic response.Following allergen inhalation, reduction in exhalation capacity of more than 20%,and for at least 10-20 minutes.Gastrointestinal symptoms within 24 hours.
Why is wheezing usually worse when asthmatic exhale?
Wheezing in asthma is typically worse during exhalation because the airflow is faster, causing the narrowed airways to vibrate more intensely. This can lead to more noticeable wheezing sounds. Additionally, the pressure changes during exhalation can cause the airways to further constrict, aggravating the wheezing.
When the heart rate varies with respirations this is called?
This is called sinus arrhythmia. It is a normal phenomenon where the heart rate increases during inhalation and decreases during exhalation. It is more commonly seen in younger individuals and can be a normal finding.
Does more energy require less strength?
no it relly does not
What does the diaphragm muscle do when air moves into the lungs?
The diaphragm moves down to make the lungs expand (inhalation)
Why would a mammals cell require more mitochondria than a lizard?
Simply put because mammalian cells require more sustained energy.
Does water require energy?
If you take energy in the form of heat, from water it will freeze and so is not water any more.
Mitochondria produce the energy for cells. This means that cells that require more energy need more mitochondria. What type of cell would need to have more mitochondria?
Muscle cells, especially those found in the heart and skeletal muscles, require a significant amount of energy to perform their functions. Therefore, they would need to have more mitochondria to meet their high energy demands.
What is a disadvantage of a multicellular organism?
They require more energy then single-celled organisms
How does a cheetah require energy?
by eating more and hunting and that gives you the ability to work.that makes the energy for the cheetah or what every animal need is energy.
