The 2000 Meter Row Essay

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

1. Why did Allen’s heart rate and blood pressure fall in this time of emergency (i.e. at a time when you’d expect just the opposite homeostatic response)? Pg. 969

Burns occur when cells are subjected to high temperatures which lead to necrosis of the cell because of enzymatic denaturing.

In the story, In Dubious Battle, the setting plays a role in representing Jim’s cleansing rebirth, although his new job is seemingly dismal. The reader first encounters Jim in a boarding house that is described as, “For a moment he sat quietly while waves of itching rolled up and down his calves; then he stood up and reached for the unshaded light. The finished room lighted up - the big white bed with its chalk-white spread” (3). This scene represents Jim's rebirth from his old life to his new. He is sleeping quietly in the darkness as if he was in a womb, but he is then suddenly awoken from sleep and he connects with the world. His calves tingle and his muscles engage for the first time signaling his transformation. Jim then stands and turns

Jim’s experiences with the pirates allows him to view Israel Hand’s death intellectually, not just emotionally. He had to defend himself against a man who saw him as an enemy not a boy. He has to go against men that are smarter and larger than himself. He is going against people bigger than himself but stays to it being brave. After the death of his father, emotionally he is upset and knows he has to take over the business for him. Shortly later, he experiences another death, which is Billy bones. It was then that he realized that the people going against him are bigger and smarter than himself. Including the other pirates. Emotionally he cries because this is his second death in a short period of time. He knows that other people are going

Once the SNS is activated, heart rate increase, blood pressure increases, breathing accelerates, and pupils dilate. All these mechanisms assist the body when dealing with stressful situations and assessing danger. The sympathetic nervous system is also known as the “fight or flight” response since it diminishes the oxygenated blood flow to the organs and allocates this resource to the muscles of the legs and arms. By increasing the blood flow to the legs and arms the individual can either attack with full strength or rapidly retreat. Once the threat has been neutralized the parasympathetic system helps the body return to its normal

When you are trying to escape from the danger, the sympathetic nervous system is active that makes your heart beats faster and starts sweating. After the danger passed the parasympathetic nervous system will prepare the body for rest. All the materials that I learned from the lectures and homework are really helpful to me. Now I understand how my brain works and what is the structure of the brains and what are they

After becoming comatose, Nick was sweating profusely, and had rapid heart and respiratory rates and elevated blood pressure. Which area of the brain interacts with the autonomous nervous system during physical stress to initiate these responses?

Stimulation of Red blood cells which brings a changes in muscles by increasing the level of oxygen, which further leads to carry oxygen and nutrition to every area of body including skin, hair bones and muscles.

Mr. Brown has hyperthermia, water moves from cells into ECF due to the level of high sodium in the blood. She has compensated mild respiratory acidosis; her Ph is slightly low.

In order to achieve greater means, there has to be a set goal and that is exactly what Jim has. Jim is

The temperature increased while the heart rate and breathing rate decreased. For example the base pre training heart rate for subject one was eighty seven which decreased to eighty five after the training program. Similarly, the breathing rate decreased as subject one took thirty one breaths in a minute compared to twenty eight breaths in minute after the training program. Unusually, the internal body temperature increased. For example the internal temperature of subject one increased from thirty two point five to thirty seven degrees. My data is mostly backed up by my research. My conclusion about the recovery time being less and the resting heart rate to be lower were correct.

(a-v)O2 Diff. :Unlike SV, in order to compensate the less SV pumped from the heart, Noah must have higher arterial-mixed venous oxygen difference because of the increasing demand of his muscular tissues. Compared to his father, Noah's amount of venous oxygen molecules was less.

During the fight-flight response, the human body releases hormones, and the brain activates the sympathetic nervous system. The sympathetic nervous system causes the heart to beat rapidly and breathing to increase. Additionally, the sympathetic nervous system redirects blood to the muscles of the skeleton and reduces pain. This readies and prepares the body to elude any harm.

The function of James’ musculoskeletal system is primarily to facilitate movement as the contraction of his muscles pull on bone to carry out an action. It also contributes to heat production for enzymes to function, stability by resisting unwanted movement and maintains his posture (Saladin, K S., 2007). This is important
