Because chromosomes carry many, many genes, a disruption of a chromosome can cause severe problems with the development of a fetus. Individuals with one (or more) fewer chromosome usually dont survive either. Can you explain why? | image | textbook_images/chromosomal_disorders_21781.png |

L_0513 | excretion | DD_0201 | This is the diagram representing the human excretory system. The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. It has following parts: The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The inferior vena cava is a large vein that carries deoxygenated blood from the lower and middle body into the right atrium of the heart. The kidneys are bean-shaped organs which are present on each side of the vertebral column in the abdominal cavity. The kidney's primary function is the elimination of waste from the bloodstream by production of urine. The ureters are muscular ducts that propel urine from the kidneys to the urinary bladder. The urinary bladder is the organ that collects waste excreted by the kidneys prior to disposal by urination. Urethra is a tube which connects the urinary bladder to the outside of the body. | image | teaching_images/human_system_excretory_6107.png |
L_0513 | excretion | DD_0202 | This is a diagram of the major organs of the excretory system. The kidneys, ureter, bladder, and urethra all play important roles in this system. The kidneys filter blood and produce urine. The kidneys are shaped like beans and are located on each side of the body. After the kidneys, urine enters into the ureter. Then the urine moves into the bladder. When the bladder is about half full, it then releases into the urethra. This is how urine is filtered out of the body. | image | teaching_images/human_system_excretory_6117.png |
L_0513 | excretion | DD_0203 | The diagram shows the human urinary system. It includes two kidneys, two ureters and a urinary bladder. Blood is filtered by the kidneys to remove waste. Excess water and waste leaves the kidneys in the form of urine through the ureters to the bladder. Contractions of muscles in the ureters move the urine down into the bladder. Urine is excreted from the bladder through the urethra by the process of urination. | image | teaching_images/human_system_excretory_6115.png |

Wear hearing protectors, such as ear plugs to protect your ears from loud sounds. Wear a safety helmet for activities like bike riding and skating ( Figure 1.2). Wear a safety belt every time you ride in a motor vehicle. Avoid unnecessary risks, such as performing dangerous stunts on your bike. Never dive into water that is not approved for diving. If the water is too shallow, you could seriously injure your brain or spinal cord. A few minutes of fun could turn into a lifetime in a wheelchair. | image | textbook_images/keeping_the_nervous_system_healthy_21941.png |

L_0586 | light reactions of photosynthesis | T_3141 | FIGURE 1.3 Photosynthesis is a two stage process. As is depicted here, the energy from sun- light is needed to start photosynthesis. The initial stage is called the light reac- tions as they occur only in the presence of light. During these initial reactions, water is used and oxygen is released. The energy from sunlight is converted into a small amount of ATP and an en- ergy carrier called NADPH. Together with carbon dioxide, these are used to make glucose (sugar) through a process called the Calvin Cycle. NADP+ and ADP (and Pi, inorganic phosphate) are regenerated to complete the process. | image | textbook_images/light_reactions_of_photosynthesis_21954.png |
