Thermal Physics: Elephant Seals Essay

The circulatory system would transport nutrients and oxygen to all the cells in the body. Organs include, heart, veins, and arteries. The respiratory system exchanges gases, like carbon dioxide, and oxygen so that the body will function properly. These two systems work together to get oxygen to move blood, to work out many organs in the body. Air goes in and out by the mouth or nose and comes in and out of the lungs. What comes in is oxygen, and that oxygen moves blood to the lungs. What comes out is carbon dioxide, and that moves the blood to the

The respiratory and cardiovascular systems work together to supply oxygen to the body’s cells, remove carbon dioxide and regulate the Ph of the body’s fluids. This system of regulation is called homeostasis. (www.wiki.answers.com, 2013)

The digestive system absorbs the minerals and nutrients from the foods that have been eaten. The break down of food beings in the mouth, where the

The esophagus receives food from the mouth after swallowing and then delivers it to the stomach. The stomach holds food which it is being mixed with enzymes which continue the process of breaking down the food into a useable form. When the contents of the stomach are processed they are released into the small intestine. In the small intestine food is broken down by enzymes released from the pancreas and bile from the liver, the food is moved through and mixed with digestive secretions. The small intestine is made up of three segments the duodenum, jejunum and the ileum, the jejunum and the ileum are mainly responsible from the absorption of nutrients in to the bloodstream. These contents start out semi-solid and end in a liquid form after passing through the organ. Water, bile, enzymes and mucous change its consistency, one the nutrients have been absorbed it then moves onto the large intestine. The large intestine connects to the rectum and is specialised in processing water so that emptying the bowels is easy.

The brown pelican has an intricate digestive system in its body. For example, the bird’s digestive system is specially adapted for consuming fish. In contrast, Pelecanus occidentalis cannot digest large fish bones, such as those from different kinds of sport fishes. Bird beaks and bills act as a mouth for the pelican. When food enters the birds’ bill, the food is sent down the esophagus to the stomach (proventriculus). The pelican then stores the food in the crop, a temporary storage solution for food for birds (Kennedy, 2005). In addition, the crop also allows the pelicans’ food to soften after entering the stomach. There are two parts of the stomach in Pelecanus occidentalis: the proventriculus and the gizzard (Kendrick 2010). In the proventriculus, specialized cells secrete pepsin. Furthermore, the food is then passed on to the gizzard, where it grinds it down to make it easier for the digestive enzymes to break down the food. Another part of the pelican’s digestive system is the small intestine, where food is digested and absorbed. The last part of the bird’s digestive system is the cloaca, which holds the waste products of digestion until they are expelled out through the vent. In addition, the large intestine connects the small intestine to the cloaca.

The circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream

Orcas have the most diverse diet of all the marine mammals. Some specimens of orcas prefer different types of marine mammals or marine life. They will mostly eat fish and squid, but will devour almost any marine animal in site. They tend to eat a wide array of fish from salmon, hering, halibut, and cod. One Orcas was found to have a harbor seal, a stellar sea lion, and a harbor porpoise in its stomach. Another orca was found to have the remains of 32 adult harbor seals in its belly (Martin.) The orca has been observed to eat river otters, squid, and

First of all, the human body, crayfish, earthworm, and frog all have many similarities and differenced about how their digestive system works. They all eat their food through their mouths and the food then travels into the esophagus. The esophagus prepares the food for further digestion. The food in the esophagus then travels in the frog, crayfish, and human body’s stomach. The earthworm doesn’t have a stomach, but it has a crop that serves as a storage stomach. Once the food is in the stomach, something different happens for each organism. The food in the crayfish travels to the digestive gland which produces digestive substances and from which the absorption of nutrients occurs. The same thing occurs in a frog and the human body, but instead of a digestive gland it is moved into a small intestine. In the earthworm, the food goes from the stomach to the gizzard, which uses stones that the earthworm eats to grind the food completely. After it is moved into the digestive gland, small intestine, or gizzard, the food is mostly digested. The earthworm and human body’s food is now moved into the larger intestine, where it absorbs water and any remaining nutrients. The frogs food is stored in something like a large intestine, but it is called the gallbladder. The crayfish only has on intestine. After going through all this, the undigested material leaves through the anus, or for a frog, it is called the cloaca.

On the Monday of May 23rd, the group were asked to turn the mink over to do a cut from the neck to mid back and skinned it. After skinning the mink, classes were required to names the muscles. Wednesday of May 25th, groups were required to take out the esophagus, stomach, small intestine, and big intestine from the mink and measured it. To make the lab easier, groups were suggested to take the liver. Slowly through the lab, students took the digestive system out to study and named as well as know the functions to them. The functions are similar to human function of digestive

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions of the Respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The Respiratory system is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

The respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.

The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine, 2016).

Each organ has a specific task that aids in the breaking down of food and absorbing of nutrients. Starting with the mouth, dogs have saliva, which is mostly water, but may contain an enzyme that slightly helps called salivary lipase. For the most part though, saliva mainly moistens the food so that it can travel easily to the stomach. There, the stomach secretes mucins, hydrochloric acid, and pepsinogen. Mucins create the protective lining of the stomach and assist in the muscular lining's ability to mix the digesta. Hydrochloric acid and pepsinogen work together to lower pH, absorb vitamin B12, digest proteins (such as chicken meal and fish meal). Dietary fats such as omega 3 fatty acids that are in fish oil would also be absorbed in the small intestine. Now, at the beginning of the stomach is the duodenum which has Brunner's glands that protect its lining. Then bile is delivered from the liver to help digest lipids. The pancreas also plays a role by producing enzymes that are essential for digesting starch, proteins, lipids, etc. So ultimately, any protein residue from the two ingredients listed would typically be utilized by this point. Then the last step is the large intestine which is the main site for water absorption. Certain products arrive in the large intestine and end up passing through because the large intestine lacks that ability to absorb it. This is the case for long-chain fatty acids, microbial cells, and B vitamins. Having said that, the end result is waste matter, also known as
