causes of death
what are some causes of death? lets find out!
| Question | Answer |
|---|---|
| what is cause of death | Every death is attributed to one underlying condition, based on information reported on the death certificate and using international rules. |
| what is the mechanism of death | The mechanism of death is the physiological derangement that results in the death. An example of a mechanism of death due to the gunshot wound |
| what is manner of death | The manner of death is the determination of how the injury or disease leads to death. There are five manners of death (natural, accident, suicide, homicide, and undetermined). |
| what are the levels of organization | Cell: The basic structural and functional unit of all living organisms. Tissue: A group of similar cells that perform a specific function. Organ: A structure made up of different types of tissues that work together to perform a specific task. |
| more levels of organization | Organism: A complete living being made up of organ system. Organ System: A group of organs that work together to perform a major function for the organism |
| what are body systems | Body systems are groups of organs and tissues that work together to perform a specific function, such as digestion or movement |
| what Is organ system | An organ system is a group of organs working together to perform a major function, like the respiratory system Key human organ systems include the digestive, which absorbs nutrients, and the circulatory system, which transports substances |
| what is respiratory system | The respiratory system's key organs include the nose, mouth, trachea, bronchi, lungs, and alveoli. The diaphragm and intercostal muscles are also crucial, as they contract and relax to drive the mechanics of breathing. |
| what is Nervous System | The nervous system's key organs/structures and their primary functions are summarized below. The entire system acts as the body's command center, coordinating actions and transmitting signals via specialized nerve cells called neurons |
| what Is the skeletal system? | The skeletal system includes bones, cartilage, and ligaments, which provide support and protection for internal organs. Key functions include allowing for movement, producing blood cells, and storing minerals like calcium and phosphorus. |
| what is the integumentary system | The integumentary system's key organs are the skin, hair, nails, and exocrine glands (sweat and oil), and its primary functions include protection, temperature regulation, and sensation |
| what is the immune and lymphatic system | The immune and lymphatic systems are interconnected networks that protect the body from infection. Key organs include the lymph nodes, spleen, thymus, bone marrow, tonsils, and adenoids |
| what is urinary system | The urinary system's key organs are the kidneys, ureters, urinary bladder, and urethra. The kidneys filter blood to create urine, the ureters transport urine to the bladder, the bladder stores it, and the urethra expels it from the body |
| what is cardiovascular system | The cardiovascular system includes the heart, blood vessels (arteries, veins, and capillaries), and blood. Its key functions are to pump oxygen and nutrients throughout the body, remove waste products, and transport hormones |
| what is reproductive system | The reproductive system produces (sperm and eggs) and sex hormones, transports and sustains the cells, and develop offspring. Key organs include testes and ovaries), which create gametes and hormones, and other structures like the uterus, fallopian tubes |
| what is Endocrine System | The endocrine system uses hormones to regulate metabolism, growth, and reproduction through glands like the pituitary (regulates other glands), thyroid (metabolism), adrenal glands (stress response), pancreas |
| what is Muscular System | The muscular system includes skeletal, cardiac, and smooth muscles, along with tendons that connect muscles to bones. Its main functions are enabling movement, maintaining posture, and providing stability |
| what is cadaver | Some common examples are the brain (control center for thought, movement, and vital functions), heart (pumps blood), lungs (gas exchange), kidneys (filter blood), and digestive organs like the stomach and intestines (break down food) |
| what is Physiological time of death | Physiological time of death is the exact moment when a person's vital organs cease to function permanently. This is the biological moment of death, marked by the irreversible loss of circulation and respiration, and is distinct from the legal death |
| what is Estimated Time of Death | Estimated Time of Death refers to a medical examiner's or forensic pathologist's best approximation of when a person's vital functions ceased. It is an estimate, usually provided as a range of time (e.g between 4 and 6 P.M.), rather than a precise moment |
| what is Legal Time of Death | In legal arenas, especially for civil matters, the time of death is defined as the moment of pronouncement as stated on a valid death certificate. |
| what is postmortem | Postmortem changes are the natural, physical processes that occur in the body after death, including cooling, the settling of blood, and the stiffening of muscles |
| what is algor mortis | Algor mortis is defined as the internal cooling of the body after death to ambient temperature due to the cessation of thermoregulation. This process is the propensity of a body to reach equilibrium with ambient temperature after death. |
| what is Rigor Mortis | Rigor mortis is the medical term for the stiffening of a body's muscles after death. This temporary condition is caused by a lack of energy (ATP) in the muscles, which prevents them from relaxing and locks the joints in place. |
| what is Livor Mortis | Livor mortis, or postmortem lividity, is a purplish-red discoloration of the skin that occurs after death due to the settling of blood in the lowest points of the body under gravity. |
| what is Decomposition | Decomposition is the process of breaking down a complex substance into simpler components, either through the natural decay of organic matter or a chemical reaction |
| what is Insect Activity | Insect activity in the biomedical field encompasses several critical areas, primarily forensic entomology, medical entomology, and biotechnology/medicine development |
