The human circulatory system consists of three main parts - the heart, lungs, and blood vessels. The heart pumps oxygenated blood to the lungs, where carbon dioxide is removed and oxygen is added. The blood is then pumped throughout the body via arteries, veins, and capillaries to supply oxygen and nutrients to cells and remove waste before returning to the heart to restart the cycle.
The circulatory system transports food, oxygen, carbon dioxide, and waste throughout the body via blood flowing through blood vessels. Blood is pumped from the heart through arteries and returns to the heart via veins, with the smallest blood vessels being capillaries. The heart has four chambers that cycle blood receiving oxygen from the lungs and pumping it out to the entire body. Unhealthy eating and lack of exercise can increase risks of heart problems like heart attacks by clogging arteries.
Arteries take blood away from the heart. The walls of an artery are made up of thick muscular walls and elastic fibres. Veins carry blood towards the heart and also have valves. Capillaries link arteries and veins, and have a one cell thick wall. Blood is made up of four main things: plasma, the liquid part of the blood; Red Blood Cells to carry oxygen; White Blood cells to protect the body from disease and platelets to help blood clot.

Addiction is a chronic disease that is likely to recur, similar to other chronic diseases like diabetes or hypertension. Treatment is most effective when it combines both medication and behavioral treatments. Research shows treatment can be very effective, even when ongoing treatment is required, as addiction may otherwise recur without continued intervention and support. The document discusses understanding addiction as a disease, whether it is acute or chronic, and variability between individuals, before directing readers to a website to learn more about specific treatment experiences.
The document discusses drug abuse and addiction through a series of questions about an experiment with rats. The experiment shows that rats administered cocaine or electrical brain stimulation to the reward system will compulsively press a lever to receive more, demonstrating how drug use becomes reinforcing. It defines addiction as a chronic brain disease characterized by compulsive drug use despite negative consequences. While drug use is initially voluntary, it can lead to long-term changes in the brain that undermine a person's self-control and ability to stop using drugs. The risk of addiction is influenced by biological and environmental factors, and the threshold for addiction is not the same for all individuals.
4.03 drugs change the way neurons communicatemelodiekernahan
Certain drugs can interfere with neurotransmission in the brain by mimicking or blocking neurotransmitters like dopamine. Drugs like methamphetamine, nicotine, and cocaine cause the release of dopamine in the brain's reward system, producing feelings of pleasure. Alcohol alters brain neurons by binding to receptors for neurotransmitters such as GABA and glutamate. The effects of a drug depend on factors like dosage, route of administration, genetics, and environmental stresses.
4.02 neurons, brain chemistry, and neurotransmissionmelodiekernahan
The document discusses neurons, brain chemistry, and neurotransmission. It describes how neurons communicate with each other through synapses using electrical and chemical signals. When a presynaptic neuron is activated, it releases neurotransmitters that bind to receptors on the postsynaptic neuron, which may excite or inhibit that neuron and propagate the signal. The brain contains billions of neurons that interact through this synaptic transmission to control functions, behaviors, and emotions.
The document discusses the structure and functions of the main parts of the brain. It explains that the brain stem regulates basic functions like breathing and heart rate. The cerebellum coordinates movement and balance. The limbic system regulates emotions. The diencephalon processes sensory information and controls the pituitary gland. The cerebral cortex is responsible for higher-level cognitive functions like thinking, language, and perception. The document also describes how brain imaging techniques like PET scans are used to study brain activity during different tasks.
3.05 making decisions in the face of uncertainitymelodiekernahan
This document discusses making decisions involving biomedical technologies when facing uncertainty. It notes that while science can help analyze uncertain situations and identify susceptible individuals through genetic screening, this ability also raises difficult ethical questions about using genetic information. Ultimately, science can determine what is possible but public policy and ethics analysis are needed to determine what should be done.

Sergei Grinkov, an Olympic gold medalist figure skater, suddenly collapsed and died during a practice session at age 28. He was found to have been born with a mutation in a single gene that affects blood clot formation, causing clots to form in the wrong places and leading to his unexpected heart attack. The document discusses how all diseases have both genetic and environmental factors that influence risk and how identifying genetic risks can help enable prevention strategies.
Molecular medicine is advancing as scientists sequence disease-related genes to better understand and treat disease. Physicians will tailor drug prescriptions based on genetic differences in how people respond to treatment. Determining the molecular structure of disease genes allows scientists to develop new treatment strategies by applying this genetic knowledge. As understanding of human genetic variation improves, diagnosis and treatment of diseases by physicians will change substantially.
This document discusses human genetic variation and how scientists study it. It covers several key points:
- Genetics is the study of inherited variation in humans. Studying human genetics helps us understand ourselves as well as treat diseases.
- Scientists use techniques like transmission genetics, cytology, molecular analysis and DNA microarrays to study genetic variation.
- While humans share much of our genetic information, no two individuals (except identical twins) have the same complete genetic makeup. There is natural genetic variation among humans.
- Understanding genetic variation is important for medicine to promote health and treat diseases. It also raises ethical issues that society must address.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
