The document provides an overview of the cardiovascular system across multiple chapters. Key points include:
- The cardiovascular system comprises the heart, blood vessels, and blood, and its main functions are distribution of oxygen, removal of waste, and thermoregulation.
- The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs through separate circulations.
- Blood flows from arteries to arterioles to capillaries to venules to veins, with higher pressure needed in the systemic circulation.
- Subsequent chapters provide details on anatomy, histology, constituents of blood, haemostasis, and electrophysiology of the cardiovascular system.
Blood has three main functions: transport, protection, and regulation. It transports gases, nutrients, wastes, hormones, and heat. White blood cells protect the body by destroying pathogens and cancer cells, while platelets help with blood clotting. Blood also helps regulate pH and water balance. It is composed of plasma and formed elements, including red blood cells, which carry oxygen and carbon dioxide, white blood cells, and platelets. Red blood cells are biconcave discs that transport oxygen and carbon dioxide via hemoglobin.
The document discusses blood, tissue fluid, and lymph. It describes:
1) Blood plasma as a pale yellow liquid consisting mainly of water with dissolved substances and no blood cells.
2) Tissue fluid as similar in composition to blood plasma but with fewer proteins, no blood cells, and varying amounts depending on pressures between blood vessels and tissues.
3) Lymph as collected tissue fluid that is returned to blood vessels through lymphatic vessels, maintaining tissue fluid composition.

Styles of Scientific Reasoning, Scientific Practices and Argument in Science ...Elsa von Licy
The document discusses various topics related to scientific reasoning, practices, and argumentation including different styles of scientific thinking, features of scientific knowledge, and teaching and learning science. It provides examples of "crazy ideas" in science that are now accepted, examines the role of argument in science, and outlines the scientific practices and central questions of science. It also discusses developing models, planning investigations, analyzing data, and constructing explanations as key scientific practices.
Anti-philosophy rejects traditional philosophy and logic, instead embracing creativity, spirituality, and personality. It considers philosophy to be dead, kept alive artificially by analytic philosophers. The document criticizes how philosophy is currently taught and argues it has become unproductive, replacing original aims with nonsense. Anti-philosophy's goal is not to destroy philosophy but to transform its current state and avoid fundamentalism in philosophy and science.
There is no_such_thing_as_a_social_science_introElsa von Licy
This document provides an introduction and overview of the arguments made in the book "There is No Such Thing as Social Science". It begins by stating the provocative title and questioning whether the authors will take it back or qualify their position.
It then outlines three ways the term "social science" could be used - referring to a scientific spirit of inquiry, a shared scientific method, or reducibility to natural sciences. The authors argue against the latter two, methodological and substantive reductionism.
The introduction discusses how opponents may accuse the authors of being a priori or anti-reductionist, but argues that those defending social science are actually being dogmatic by insisting it must follow a scientific model. It frames the debate as being
