  • Circulation Of The Blood In Superficial Capillaries
    1,459 words
    The Circulatory System The circulatory system in anatomy and physiology is the course taken by the blood through the arteries, capillaries, and veins and back to the heart. In humans and the higher vertebrates, the heart is made up of four chambers the right and left auricles, or atria, and the right and left ventricles. The right side of the heart pumps oxygen-poor blood from the cells of the body back to the lungs for new oxygen; the left side of the heart receives blood rich in oxygen from th...
  • Large Number Of The Cetacean's Ribs
    831 words
    Cetaceans There are many forms of cetacean life living in the worlds waters. How an why they came into existence is uncertain, but there have been many theories. Some say that dolphins are aquatic forms of goats, and others believe they evolved just like everything else, from a single cell, and not from an actual multi-cellular being. Because most cetaceans have some vestigial structures such as under-developed os coxae, the former of these two theories remains prevalent in most researchers mind...
  • Relationship Between Cardiovascular Conditioning And Stress Levels
    1,426 words
    Cardiovascular conditioning can be defined as the efficient transport and utilization of necessary oxygen and nutrients to the tissues of the body. The cardiovascular system needs to be well conditioned to enable the body to deliver adequate oxygenated blood and nutrients to the working muscles, in addition to improving the muscles capacity to use extra oxygen. Cardiovascular training is the most important style of training both for general health and for overall athletic performance. Exercising...
  • Risk Like Blood
    904 words
    Running the Race to Obtain the Prize? Each year athlete's ability to perform seems to increase by leaps and bounds. Some reasons for this can be attributed to better training methods, better conditioning techniques, and better over all health of the athlete. While most situations involve one or more of the previously scenarios, some athletes always seem to take it to a step further. They engage in a process called blood doping. This procedure does increase physical performance and athletic abili...
  • Blood Vessel
    502 words
    1) To overcome many of the obstacles on the path of any life function, specifically gas exchange, evolution has provided many adaptations. Some of these are the gills fish have developed, some insects ability to diffuse oxygen to individual cells or a moist diffusion barrier in humans. Fish have developed a trait called countercurrent exchange, in which blood passes through vessels in a direction opposite to that of water flowing over the gills of the fish. This allows the oxygen-rich water to f...
  • Beluga Whales Like Other Marine Mammals
    737 words
    A. Swimming. 1. In general, beluga whales are slow swimmers. They commonly swim about 3 to 9 kph (1.9-5.6 mph). They are, however, capable of sustaining a maximum speed of 22 kph (13.6 mph) for as long as 15 minutes (Nowak, 1991; Ridgway and Harrison, 1981). 2. Belugas can swim forward and backward (Nowak, 1991). 3. Beluga whales often swim at depths barely covering their bodies (Ridgway and Harrison, 1981). B. Diving. 1. Beluga whales typically don't dive very deep, usually to about 20 m (66 ft...

  • Diffusion Of Oxygen From Red Blood Cells
    1,310 words
    Physiological Adaptations of the Plesiosaur for 'Holding its Breath " By Nathan Eaton One hundred and fifty million years ago, large aquatic species of reptile such as the Plesiosaur dominated the ocean, and were pre-eminent predators of the sea. The branch of now extinct Plesiosaurs, or 'near lizards', evolved into variant closely related species specialised to take different niches in the food chain. Such species of Plesiosaur include the phenotypically similar Plesiosauroid and Pliosauroid. T...
  • Diffuse The Oxygen Into The Blood Cells
    814 words
    We as humans need a way to gather oxygen from our environment to survive. In response our body has a system that carries out respiration which is the of oxygen to the blood and the disposal of the waste product carbon dioxide. In the human breathing process the first step is the breath in. First we open the mouth and expand our lungs to bring in air. The first place the air traves into our mouths which is an opening in the human body used for taking in air, food, and the releasing of carbon diox...
  • Deep Diving Animals
    533 words
    When a diver dives deep for a period of time, breathing regular compressed air, a certain amount on nitrogen will be dissolved in the blood. If the diver comes back up to the reduced pressure of the surface too quickly, small bubbles of nitrogen will form in the blood stream. This is called "the bends" and requires the person to spend some time in a decompression chamber to gradually reduce the pressure and allow the nitrogen to escape the body. Some animals goes down much deeper then we do, so ...
  • Oxygen The Red Blood Cells
    1,617 words
    Hypoxia Hypoxia is a condition in humans that is caused by the reduction in partial pressure of oxygen, inadequate oxygen transport, or when tissues are simply unable to make use of the oxygen provided. This disease occurs in the tissues and brain. It results in a shortness of breath, and an overall impairment of function. Anoxia is the extreme form of hypoxia, and it occurs when there is absolutely no oxygen at all in the body that the brain and tissues can make proper use of. There are five di...
