Chapter 20
Blood vessels form a closed system that begins and ends at the heart. There are three main types of blood vessels - arteries, which transport blood away from the heart; capillaries, which allow for exchange of materials between blood and tissues; and veins, which carry blood from the capillaries back towards the heart. Arteries branch into smaller arteries and then arterioles, which feed into capillary beds. Blood then drains from the capillaries into venules and veins of increasing size until emptying back into the heart, completing its 60,000 mile journey through the body transporting blood to and from tissues.
Chapter 6
Chemical bonds form between atoms to achieve more stable arrangements with lower potential energy. The type of bonding depends on differences in electronegativity between atoms. Ionic bonds form between ions, covalent bonds involve shared electron pairs, and metallic bonds result from delocalized electrons shared among many atoms in a lattice. Molecular geometry and intermolecular forces also influence molecular properties.
Heart
The three main chambers of the heart are the two atria which receive blood, and the two ventricles which pump blood out of the heart. The right side receives deoxygenated blood and pumps it to the lungs, while the left side receives oxygenated blood from the lungs and pumps it out to the body. One-way flow is ensured by atrioventricular and semilunar valves. The cardiac cycle involves the coordinated contraction and relaxation of the heart chambers.
Skeletal System - Chapter 7
The axial skeleton is divided into the skull, vertebral column, and bony thorax. The skull is made up of 22 bones including the cranial and facial bones. It protects the brain and houses the sense organs. The vertebral column consists of 26 irregular bones that form a flexible column protecting the spinal cord. The bony thorax includes the ribs, sternum, and costal cartilage and protects the heart and lungs.
Gases
1) Pressure is defined as force per unit area. The greater the force on a given area, the greater the pressure.
2) Gas pressure is caused by collisions of gas molecules with each other and surfaces. The pressure exerted by a gas depends on its volume, temperature, and number of molecules.
3) Boyle's law, Charles' law, and Gay-Lussac's law describe the relationships between pressure, volume, and temperature for an ideal gas. Boyle's law states that pressure and volume are inversely proportional at constant temperature. Charles' law states that volume and temperature are directly proportional at constant pressure. Gay-Lussac's law states that pressure and temperature are directly proportional at constant
Cell Respiration
Metabolism involves the chemical processes that take place in organisms. There are catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Energy exists in various forms like kinetic, potential, and activation energy, and it can be transferred and transformed according to the laws of thermodynamics. Cellular respiration uses energy from molecules to make ATP through glycolysis, the Krebs cycle, and the electron transport chain, but anaerobic respiration occurs without oxygen through fermentation pathways.
The Lymphatic System
The lymphatic system consists of lymphatic vessels and lymphoid tissues that work with the circulatory and immune systems. The lymphatic vessels collect excess fluid from tissues and return it to the bloodstream to prevent fluid buildup. They also transport immune cells called lymphocytes throughout the body. Lymphoid tissues including the spleen, tonsils, adenoids, and lymph nodes filter the lymph and help the body fight infection and disease.
Genetic Mutations 2
Genetic mutations are changes in DNA sequence that can be caused by environmental factors or spontaneously. There are three main types of mutations: point mutations which change a single base pair, frameshift mutations which add or delete a base changing subsequent amino acids, and chromosomal mutations such as deletions, insertions, inversions or translocations of chromosome segments. Mutations can cause genetic disorders like cystic fibrosis, osteogenesis imperfecta, multiple neurofibromatosis, Klinefelter syndrome, twin-to-twin transfusion syndrome, fragile X syndrome, and Tay-Sachs disease.

The document advertises forensic science workshops and programs for kids hosted by the International Forensic Science Research organization. It provides details on various workshops covering topics like fingerprints, impression evidence, forensic entomology, ballistics, and blood spatter. It also describes a two-day mock murder investigation program held at schools. Additionally, it mentions 2-3 week long exposure programs taught by experts in different forensic fields and seminars with guest forensic experts. Contact information is provided at the end.
The Immune System
The immune system protects the body from infection and disease. It has both innate (nonspecific) defenses that provide immediate response and adaptive (specific) defenses that provide long-term protection. The innate system includes physical and chemical barriers that prevent pathogen entry. If barriers are breached, inflammation responds. The adaptive system recognizes specific pathogens using B cells and T cells. It has memory to mount stronger responses. Diseases can compromise immune function.
Blood
Blood is composed of plasma and formed elements including red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide throughout the body. White blood cells help protect the body from infection and disease. Platelets are cell fragments that help form blood clots to stop bleeding. Careful matching of blood types is important for safe transfusions, as incompatible blood can cause a dangerous immune response.
The Cell Membrane
The plasma membrane functions as a selective barrier controlling what passes in and out of cells. It is composed of lipids and proteins arranged in the fluid mosaic model, where lipids form a fluid bilayer and proteins float freely within it. Materials cross the membrane through passive transport mechanisms like diffusion, osmosis, and facilitated diffusion which do not require energy, or active transport processes like carrier-mediated transport, endocytosis, and exocytosis which use cellular energy.
Introduction to forensic science
This document provides an introduction to forensic science. It defines forensic science as using scientific methods to examine information about the past, especially for legal purposes. Forensic science originated in ancient Rome where criminal cases were presented before public forums, with the best argument determining the outcome. The document outlines several fathers of modern forensic science disciplines like toxicology, ballistics, and fingerprinting. It traces the origins and development of forensic science from ancient accounts to its systemization starting in 16th century Europe. Key fields of forensic science discussed include toxicology, ballistics, anthropometry, and fingerprints.
Principles of forensic science
The document discusses the seven basic principles of forensic science:
1) The law of individuality states that every natural or man-made object has unique identifying features. Extensive work in fingerprints has verified this.
2) The principle of exchange means that when a criminal comes into contact with a victim or crime scene, they leave traces and pick up traces from the contact.
3) The law of progressive change recognizes that everything changes over time, impacting how criminals, crime scenes and evidence can be identified.
DNA Replication and Protein Synthesis
The document summarizes the processes of DNA replication and protein synthesis. DNA replication involves separating DNA into two strands and using each strand as a template to make an identical copy, resulting in two double-stranded DNA molecules. Protein synthesis involves transcription of DNA into mRNA, which is then translated on ribosomes into a polypeptide chain using transfer RNA to add amino acids specified by mRNA codons.

Cellular Respiration - AP Biology
Metabolism involves the chemical processes that take place in organisms. There are two main types of metabolic pathways - catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Cellular respiration uses catabolic pathways to break down glucose and other food molecules, releasing energy that is captured in ATP. There are four main stages of cellular respiration: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain. When oxygen is absent, cells carry out anaerobic respiration like lactic acid fermentation or alcoholic fermentation to regenerate NAD+ and allow glycolysis to continue producing a small amount of ATP.

Environmental factors and spontaneous errors can cause genetic mutations, leading to disorders such as cystic fibrosis, fragile X syndrome, and Tay-Sachs disease.
DNA History & Structure
The document discusses the history and structure of DNA. It describes how DNA was discovered to be the genetic material through experiments in the 1800s and 1900s. Key figures like Watson, Crick, Franklin and Chargaff contributed to determining DNA's double helix structure and the rules of base pairing between A-T and G-C. The structure forms a spiral with the bases on the inside and a sugar-phosphate backbone on the outside, held together by hydrogen bonds between the paired bases.
Cell Respiration
Metabolism involves the chemical processes that take place in organisms. There are catabolic pathways that break down molecules and release energy, and anabolic pathways that use energy to build molecules. Energy exists in different forms like kinetic and potential energy, and transformations are governed by thermodynamics laws. Cellular respiration uses energy from food molecules and involves glycolysis, breakdown of pyruvic acid, the citric acid cycle, and the electron transport chain, requiring oxygen. Without oxygen, anaerobic respiration like lactic acid fermentation allows glycolysis to continue to produce ATP.
Cell respiration revised09
Metabolism involves the chemical processes that take place in organisms. There are catabolic pathways that break down molecules and anabolic pathways that build them up. Aerobic respiration fully breaks down molecules with oxygen through glycolysis, pyruvate breakdown, the citric acid cycle, and the electron transport chain. Anaerobic respiration occurs without oxygen through fermentation pathways like lactic acid fermentation in muscles or alcoholic fermentation in yeast, allowing glycolysis to continue without oxygen as the final electron acceptor.
Periodic Law
The document summarizes key concepts about the periodic table, including its history and development. It describes how Mendeleev organized the elements and made predictions that were later confirmed, establishing the periodic law. Over time, the periodic table was refined as new elements were discovered and atomic number was established as the basis for organization. The document also outlines periodic trends in properties like atomic radius, ionization energy, and electronegativity.

The Periodic Law
1) The periodic table was developed in the 1860s by Russian chemist Dmitri Mendeleev to show relationships between elements.
2) Mendeleev arranged elements by atomic mass and was able to predict properties of undiscovered elements.
3) The modern periodic table is arranged by atomic number instead of mass and new elements have been discovered and added over time.
Tour of the Cell
Cells can only be seen under a microscope as most are too small to see with the naked eye. Light microscopes use visible light while electron microscopes use electron beams, allowing for much higher magnifications. All living things are composed of cells, which are the basic structural and functional units of life. Cells contain organelles that carry out specific functions and the cytoskeleton provides structure and helps with movement. Plant and animal cells differ in some of their organelles like cell walls and chloroplasts. Cells communicate through channels and junctions between them.
The Skeletal System - Chapter 6
The document summarizes key aspects of the skeletal system, including:
1. Bones develop from cartilage early in development and continue changing in structure throughout life.
2. There are 206 bones in the human body classified as either axial or appendicular based on location and role.
3. Bones are living tissues composed of both organic and inorganic materials and have distinct structures depending on their shape and role.
4. Bones continuously remodel through the processes of deposition and resorption to maintain strength and mineral homeostasis.
