  • Circulatory System - 1,361 words
    CIRCULATORY SYSTEM (A) FORMATION OF TISSUE FLUID AND EXCHANGE OF MATERIALS IN THE CAPILLARY NETWORK In a capillary network, two opposing forces mainly determine the movement of fluid between the blood and tissue fluid: (1) the hydrostatic pressure difference and (2) the osmotic potential difference between the blood and the tissue fluid. In the part of the capillary network near the arterial end, blood pressure is much higher than that of the tissue fluid so that the difference in hydrostatic pressure exceeds the osmotic difference between the two fluids. As a result, some plasma is filtered out of the capillaries under pressure into the tissue space to form tissue fluid. As blood moves alon ...

    ... her factors include abnormalities in the proteins that regulate blood cell production and a malfunctioning immune system that interferes with the normal blood cell production. Certain environmental factors have been associated with the development of plastic anemia. Chemotherapy drugs such as busulfan or antibiotics such as chloraphenicol can cause temporary or prolonged plastic anemia. Chemicals such as benzene and pesticides, infections such as viral hepatitis and mononucleosis, autoimmune disorders and ionizing radiation also has been linked to the development of plastic anemia. Although exposure to these agents increases the risk of developing plastic anemia, it is proven that they a ...

  • The Human Circulatory System - 1,932 words
    The Human Circulatory System The human circulatory is one of, if not the, most important system in the body. It consists of such organs as the heart, and lungs (Dunbar 4). However every organ and organ system in the body is nourished and kept alive through the use of the circulatory system (2-4). The main organ in the circulatory system is the heart. Basically, the heart is a pump that keeps fresh blood coursing through your body, bringing oxygen and nutrients to all your organs and cells (2). A mathematical description of what the heart accomplishes is astonishing. Your heart keeps approximately ten pints (4.73 liters) of blood constantly circulating through seventy five thousand miles (one ...

The aggressive behavior starts in the adolescent stages of life and may continue into adulthood. Where does the aggressiveness originate? Part of the explanation is that children who are sociable and spontaneous exhibit more aggressive behavior than those who do not. Surprisingly, common traits amongst these children are being first born, having a stable family life and a shy temperament. More current, up to date explanation state that aggression is learned response to frustration and by observing others who exhibit the same aggressive behavior. Males also are at greater risk for developing cr ...

Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613C, melts at 817C, and has a density of 5.72. (see Figure 2-A) The element has been known for centuries and can be easily obtained from ores such as arsenopyrite (FeAsS), realgar (As2S2), orpiment (As2S3), and arsenic trioxide (As2O3). There are many uses for arsenic. Among the ...

  • Biology And Human Evolution - 1,381 words
    Biology And Human Evolution Human Biology and Evolution Humans are Alive The earliest human life form can be traced back more than 3.5 billion years ago. Humans are said to be descendants of a single celled ancestor. Although they are different in size and shape all basic functions are alike. The more complex the organization of the cell became the more successful and developed it became. As these single celled organisms developed they became known as pre-humans. We share many characteristics with these pre-humans. Some of these characteristics include the masters of heredity DNA and RNA as well as proteins composed of amino acids, membranes or bound cells and lastly controlled cell division ...

The class Insecta is divided into 2 subclasses: Apterygota, or wingless insects, and Pterygota, or winged insects. Subclass Pterygota is futher divided on basis of metamorphosis. Insects that have undergone incomplete metamorphosis are the Exopterygota. Insects that undergo complete metamorphosis are the Endopterygota. Insects have an outer bilateral exoskeleton to which the muscles are attached to and provides protection for internal organs. The body is divided into 3 main parts which are the head, which include mouthparts, eyes, and ...

  • Birth Control Is Defined As Various Ways Used To Prevent Pregnancy From Occurring Birth Control Has Been A Concern For Humans - 1,423 words
    Birth Control is defined as various ways used to prevent pregnancy from occurring. Birth Control has been a concern for humans for thousands of years. The first contraception devices were mechanical barriers in the vagina that prevented the male sperm from fertilizing the female egg. Other methods of birth control that were used in the vagina were sea sponges, mixtures of crocodile dung and honey, quinine, rock salt and alum. We have come a long way from past time times of contraceptives, although some of the same concepts are still used. The least effective form of birth control used today is The Natural Method. This method is also the cheapest because the woman monitors her menstrual cycle ...

  • Cardiac Pacemakers - 1,382 words
    Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to contract and squeeze blood into the ventricles, which contract and force blood into the aorta and pulmonary arteries. Abnormalities of the heart rhythm, called arrhythmias, can disrupt this normal ca ...

  • Chrominimum - 574 words
    Chrominimum Chris Nicholatos 11/29/99 Mr. Cicero Block-D Chromium Chromium is a metal found in natural deposits as ores containing other elements. Chromium is a steel-gray, hard metal that is very brittle. It is classified as a heavy metal. After its refined from the ore chromite its compounds are used in leather tanning and manufacturing of chromic acid, pigments, and corrosion-resistant chrome products. The greatest use of chromium is in metal alloys such as magnetic tapes, paint pigments, cement, paper, and stainless steel. It is also used as an ingrediant in drilling mud, which is used to drill oil wells. Humans do need a certain amount of trivalent chromium to maintain good health. Alth ...

  • Diabetes - 3,161 words
    Diabetes Diabetes Diabetes, Diabetes Mellitus, is a chronic illness this means that it has no cure and the symptoms persist over a long period of time. This illness is a result of an imbalance of hormones, insulin, produced in the pancreas. Insulin plays an important role in how the body uses food. Insulin enables the cells in the bloodstream to absorb and use glucose for fuel. If the pancreas produces too little or no insulin or if the insulin doesnt work properly the person may become diabetic. Therefore, diabetics are not able to properly convert food into fuels needed by the body to function, which can seriously lead to physical consequences. The pancreas, located behind the stomach, is ...

  • Earthworms - 429 words
    Earthworms Earthworms are classified as Annelida. Annelida mean little rings which refers to the many segments in their body. The structure of an earthworms body is made up of more than one hundred segments separated by partitions that divide the coelum. All segments are identical except by the anterior and posterior ends. The anterior segments reflect the cephalization that is an adaption of burrowing. The head of the earthworm contains the sense organs. The muscle lines that make up the interior body wall are circular and longitudinal. Earthworms move by anchoring some segments by their setae and contracts the circular muscles in front of those segments, producing fluid pressure in the ant ...
