Endothermy has a lot of benefits and costs compared to ectotherms. Endotherms depend on their bodies metabolism to produce enough heat to raise their body temperature. Endotherms balance heat production with heat loss. Each endotherm has a range of environmental temperatures that keeps its body stable and it does this by regulating the heat loss and heat production. They regulate their body heat by vaping their metabolic rate and change its rate of heat loss by adjusting their insulation.…

Once the P wave initiates the signal, the R wave is the first upward deflection after that. Anyone can easily recognize it on the electrocardiogram (ECG). That is because it is the largest one out of all the waveforms. The R wave corresponds to the depolarization of the left and right ventricles. It does not need the Q wave to be the first deflection at all. Also, note that there can be multiple R waves. Throughout the paper, it will discuss all the wave functions, specifically the R wave, any…

The accepting attending physician visited with her. While speaking with her, the physician told her about her options going forward with her care. He wanted to do a cardiac ablation, a procedure used to scar the tissue of the heart decreasing or interrupting extra electrical pathways that cause AFib. The patient did not want the procedure due to it being invasive; however, the physician purposely worded his phrases to…

Why couldn’t we have let the patient die in peace?” (Hoffman, 2006, p.1) By using pathos and imagery to evoke sadness from the reader, the author makes one feel as if it is their family member having CPR. In extreme cases like a patient going into cardiac arrest, it is challenging to determine who should have the final say whether one should do CPR on the dying patient. According to the law, the family has control to decide, however, the article uses medical opinions to sway the reader’s…

Picture this… You are in 8th grade running around at basketball practice going through your drills when you look around and realize that one of your teammates is not at practice. You think to yourself that it is really weird because he never misses practice. That’s the last you really question it until you hear the gymnasium doors swing open. You look over to the doors and see your teammate walk through the door. You see he has wires hooked up to his chest and connected to a machine. You over…

smooth, cardiac and the skeletal muscle tissue. The smooth muscle tissue is found inside organs like the stomach, the blood vessels and the intestines. The smooth muscle tissue is an involuntary muscle, meaning it functions on its own without been controlled. The main function of the smooth muscle tissue is to make organs tightens to move substances in and out of the organs, and it is mainly controlled by the unconscious part of the human brain. The second type of muscle tissue is the cardiac…

Legs are an important part of human life. Humans use their legs in almost every aspect of their life. For athlete's, legs are also very important. One important muscle group of the leg includes the quadriceps muscles, otherwise known as the quadriceps femoris. The quadriceps are made out of four other different muscles, that all work towards a specific function for the body. Although it might not be one of the most important muscles, the quadriceps muscles are a very important leg muscle that…

When bones and muscles connect a joint is formed. At this point both are joined together by the help of tendons, which is a connective tissue. When we have to move a joint the muscle receives an electrical signal from brain. It causes movement to occur, because this causes the contraction in it. This contraction pulls on the corresponding bone at its insertion point. Stationary bone is called the point of origin for the skeletal muscle, while the one which moves is known as the point of…

the body, among other functions. The muscular system is associated with the activities of the legs, arms and other things, muscles also control facial expressions, movements and respiration. There are three types of muscles, skeletal smooth and cardiac, skeletal muscles are the only voluntary muscle tissues in the human body. The smooth muscles are found inside organs such as the stomach and the intestines, and in blood vessels. It is called a smooth muscle because…

such as walking and flying and involuntary internal functions such as pumping blood (Poultry Hub, 2016). The muscular system of poultry is made up of three different types of muscles: Smooth, Cardiac, and Skeletal. Smooth muscles are a type of involuntary muscle tissue located in the internal organs. Cardiac muscles are involuntary muscles that pump blood throughout the body of the poultry. Skeletal muscles are voluntary muscles that move the joints and are the most common type of poultry meat…
