Circulatory System Essay

This experiment was conducted to see how exercise affects breathing and heart rates. My hypothesis was that if exercise puts strain on the body, then the heart and breathing rates will increase and I was correct. This is because as the exercise increased the heart and breathing rates also increased. For example in trial #1 the resting heart rate was 96 beats per minute then after 1 minute of exercise it increased to 144 beats per minute and then increased again to 160 beats per minute after 4 minutes

cilia, not muscles. Their feeding system includes oral tentacles that prevent large particles from even entering the mouth. Food particles are then captured in mucus and moved via cilia to their mouth. - Physiology components (body systems): Circulatory: Their circulatory system is very simple and resembles a primitive fish in its general layout. They don't have a heart or blood cells. Respiratory:They breath through their skin and don't have a respiratory system

Blood works in the body in many ways. All of the blood in the human body comes from your circulatory-system. The job of the circulatory system is to pump blood to all parts of the body. There are two types of blood cells in the body. White blood cells and red blood cells. A person has millions of red blood cells, and these cells contains a chemical called hemoglobin, it is the part of your body that contains iron, carries oxygen throughout the body, and gives blood its red color . There is not as

pig, and human all have much in common; however, some have more in common than others. Many have a matching digestive system but not a matching skeletal or circulatory system. Thought numerous dissections we can compare and contrast the various animal systems and gain knowledge on more than just the external side of an animal. All 5 species have a working-normal digestive system. Although the frog, earthworm, fetal pig, and human all have an intestine. The starfish is not much alike. It has a stomach

biologists have had unique troubles with analysing the way the systems of the Daphnia function. Biologists have argued, that the circulatory system of a Daphnia relies on diffusion or convection. However, it has been decided that depending on the oxygen levels in the environment will affect the way that the circulatory system of the Daphnia functions. The levels of haemoglobin will also affect the functioning of the circulatory system in the water flea. Haemoglobin is a red blood cell, assisting the

All organisms require a large surface area in their gas exchange system, having a larger surface area to volume ratio increases the efficiency on gas exchange. Each of the 3 organisms, diving mammal, fish and aquatic insects all have a large surface area and have different ways of increasing this. Diving mammals increase their surface area by folding the tissue on the alveoli of the gas exchange mechanism fold back on itself, these fold in the alveoli increase the surface area. Fish have filaments

The circulatory system which is present in the chest consists of heart and blood vessels such as arteries, veins and capillaries (Australian Indigenous Healthinfonet, 2016). The heart being the centre controls the blood circulation throughout the body receives deoxygenated

or damaged parts of the human body. The incredible bionic man is the world’s first attempt at a fully functioning human robot with organic body parts. Rex can see, walk, talk, grasp objects and hear. Not only this, but has a fully functioning circulatory system with a heart, lungs, spleen, pancreas and artificial blood. To begin, the Bionic Man has one of the most innovative

they do in fact have a backbone. Thus, all vertebrates have cardiac, smooth, and skeletal muscle. First, cardiac muscle is only found in the heart. Unlike skeletal muscle, cardiac muscle can trigger action potentials without input from the nervous system because of ion channels in their plasma membrane. Resulting in the rhythmic cycles discussed earlier. Second, smooth muscles, derived in hollow organs and blood vessels, are responsible for involuntary body activities; such as churning of the stomach

CARDIOVASCULAR SYSTEM The cardiovascular system is also known as the circulatory system, which is an organ system that encompasses the heart and blood vessels of the body. The heart and blood vessels of the circulatory system adapt to repeated sessions of exercise in number of ways, the cardiovascular system carries blood, oxygen and nutrients to the organs and tissues of the body and carries waste products and carbon dioxide from these tissues to be removed from the body.
