What is the muscle that when contracted, it allows the lungs to fill with air?

Step-by-step answer

P Answered by PhD

It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.

URGENT PLS HELP WILL MARK BRAINLIEST The players of a high school football team were traveling home from their football game in Fernandina Beach, Florida. It had been a tough night. It was August and still hot. The game had lasted three hours, and the players had to play offense, defense, and special teams because there were not enough players to field all positions. During the bus trip home, several of the athletes consumed multiple energy drinks in an attempt to regain their strength for a celebration party they planned to attend later that evening.

What gives the athlete action are the waves of chemical and electrical charges. These charges move along the neuron and when the nerve impulses, the electrical charges across the cell membrane reverses and charges high speeds. The environmental and behavioral factors which led to Joseph's dehydration event are: For one, FLORIDA. Forget it being August and still hot. It's January, 80 degrees during winter are you kidding me?! On a serious note, the hot and dry weather caused extreme heating in Joseph's body and the loss of water in his bloodstream via sweat, this in combination with strenuous physical work during his three hour game. His inability to rehydrate caused him to experience symptoms of heat illness: dehydration, muscle pain and cramping The opening of the potassium and sodium gate was caused by the brief bonding in the motor end plate. When these two are open in the same duration, End Plate potential is present. The adjoining muscle regions are stimulated to create action potential instead of actually creating the action potential. With the lack of sodium because of the sweating with no rehydration, the sodium gate didnt open right and thats where the imbalance occurs.The gates opened at different times and caused Joseph's cramping.

1. The signal transmission across a myoneural junction that allows the nervous system to move the muscles of a football player during the game is when the chemical and electrical charges run through the neuron, then these charges redirect into one direction and continue at high speeds.

2. First he was dehydrated because of the game and then the continuous drinking of the energy drinks made it worse. The game would be environmental, the energy drinks would be behavioral.

3. The caffeine heightened the muscle contractions and made him feel more pain. This contributed to it because the caffeine caused the muscles to contract more than usual making it worse than it could have been.

4. Because they help add electrons to the body making the muscle relax more and stop cramps and contractions. They put these minerals in the drink because, during dehydration, sodium and potassium levels are lowered in order to try and replenish that hydration so, because they add these minerals, your body is able to replenish them faster.

Biology

When you exercise, your muscle cells use oxygen to convert the energy stored in glucose into the energy stored in ATP, which they then use to drive muscle contractions. When you exercise, your muscles need more oxygen. Therefore, to maintain an adequate oxygen level in all of the tissues in your body, you increase respiration rate and depth. This allows you to take in more oxygen. Your heart rate increases, which allows it to deliver more oxygenated blood to your muscles and other organs that will need more oxygen. Is this an example of a positive

Step-by-step answer

P Answered by PhD

This is an example of a positive feedback loop.

Explanation:

Positive feedback loops is a process in which a change caused by the given condition, causes another additional change in the same direction of that process. For example, the condition which is given in the question says that for exercise energy is needed and for that body made some changes which increased the concentration of oxygen in the blood. The negative feedback loop is a process in which a change caused by the given condition, causes another change in the opposite direction of that process and it decreases or stops it.

Here, positive feedback is happening for that every change is adding another change in the same direction.

Physics

Joe is hiking through the woods when he decides to stop and take in the view. He is particularly interested in three objects: a squirrel sitting on a rock next to him, a tree a few meters away, and a distant mountain. As Joe is taking in the view, he thinks back to what he learned in his physics class about how the human eye works. Light enters the eye at the curved front surface of the cornea, passes through the lens, and then strikes the retina and fovea on the back of the eye. The cornea and lens together form a compond lens system. The large

Step-by-step answer

P Answered by PhD

A) correct answer is C, B) correct answer is b and C) The correct answer is b

Explanation:

In the exercises of geometric optics, the equation of the constructor tells us the location of the image.

1 / f = 1 / p + 1 / q

where f is the focal length of the cornea-crystalline system, p and q are the distances to the object and the image.

In this case, the distance to the image on the retina is constant, about 3 cm. Therefore depending on the distance to the object) p = the focal length must change

1 / q = 1 / f 1 / p

let's apply this expression to our case

A) indicates that the tree is at a medium distance

so that the image is formed on the retina THE SAME AS

correct answer is C

B) The squirrel is at a smaller distance (p ') than the tree (p), therefore if we substitute in the equation above we find that q must decrease. Consequently the image is in front of the retina

The mountain is very far, suppose in infinity, so the image is BEHIND THE RETINA

therefore the correct answer is b

C) The squirrel is very close so the curvature of the lens INCREASES, resulting in a DECREASE in the focal length

The correct answer is b
