Grasshopper Circulatory System Essay

will prepare for it by increasing the heart rate slightly. ACTIVITY RESPONSE: The start of exercise, there are nerve centres in our brain which become aware of the cardiovascular activity. This results in adjustments which start the cardiovascular system to help increase our heart rate and also the local blood flow is improved to the right proportion to the intensity of activity. INCREASED BLOOD PRESSURE: Our blood pressure is the pressure of the blood against the walls of our arteries and…

Introduction: When you first take a look at the maned wolf you notice it's similar look of it's face to a red fox but it's long legs are what make you take a second look. It kinda reminded me of that scene in Harry Potter and the Prizoner of azkaban ,when professor Lupin turned into that hideous werewolf ,with those freakishly long legs.Even though this species has the word”wolf” in it's name, and has a face of a fox , and the long legs like the ghazelle.It is in fact none of them. Genus…

8)Thermoregulation is the process your body goes through to keep your body's temperature regulated to 60-38°C. 9)The hypothalamus is the portion of the brain that monitors and regulates the body's temperature. 10a)The body will expand blood flow in the skin and have the sweat glands produce more sweat. 10b)The body will restrict blood flow in the skin and have muscles shiver to generate and keep heat. 11a)The stimulus is the hypothalamus sensing to little heat in the body and the response is…

Oxygen In the air the basic form how you can find is O2 Dioxygen, the air contain around 20% of oxygen. Oxygen enter in the Human body by the respiratory system so pass by the mouth or nose , pharynx, larynx, trachea, main bronchi , then the lung and alveoli. For the take a breath the body needs the contraction of one muscle the diaphragm that needs energy. Energy needed is Adenine tri phosphate (ATP). The…

with fresh O2 and then moves out of the lungs via pulmonary veins and moves out of the other chambers of the heart and to the body and once again completes the cycle. It stands to reason that due to the short distance of a trip through the pulmonary system pressure in the lungs would be less than arterial pressure. So imagine if you will that the pathways in the lungs were narrowed and the pressure increased. The right ventricle (which is responsible for moving blood into the lungs) would have…

As a mammal, kangaroo has a respiratory system similar to human respiratory system. They breathe though their nose and mouth. They have a diaphragm and a pair of lungs which are sealed in pleural membranes inside the chest cavity and protected by ribcage. The lowering of diaphragm and expanding of ribcage create a negative pressure in lungs to draw air into lungs, so-called inspiration. Their breathing is linked to their hopping. During locomotion, the diaphragm move up to push out air of…

1. Explain the relationship between the skeletal and muscular systems. The relationship between the skeletal and muscular systems is that the muscular is responsible for the movement of the human body. Which is attached to the bones of the skeletal system. The skeletal performs vital functions like support, protection, and movement. 2. Why is the circulatory system important? The circulatory system is important because it transports blood and other materials throughout the body. Without the body…

organ that we need in order to pump blood to our body. The cardiac cycle and blood pressure (BP) are two things that greatly affect how our body can function. Both are a part of the circulatory system. There are many diseases that can affect the cardiac cycle and the BP. These diseases can affect our circulatory system, lungs, and our heart’s ability to function properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The cardiac cycle is what…

Introduction Congenital Heart Disease is apart of the respiratory system. The respiratory system is very important and fragile. It constitutes many functions with in the body. Congenital heart disease (CHD) is a series of cardiac defects. This disease is mostly prevalent at birth. However, it can develop at a later stage in life. It has become very significant in adulthood. There are many forms of CHD. For example, atrial septal defects and ventricular septal defects. The heart is a very complex…

Introduction: A cardiac output, also know as minute volume is the volume of blood ejected from the left or right ventricle of the heart in one minute. It’s the primary determinant of oxygen transport within the heart and entire body. Sufficient blood flow is highly important especially during exercise because the body will need much more oxygen. With the need for more oxygen, the heart will begin to beat and pump faster during exercise. As the heart rate increases so will the blood flow, also…
