In Da Club - Membranes & Transport: Crash Course Biology #5

Hank describes why plants are so freaking amazing - discussing their evolution, and how their cells are both similar to & different from animal cells.

Plant Cells: Crash Course Biology #6

In which Hank does some push-ups for science and describes the "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.

ATP & Respiration: Crash Course Biology #7

Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide, and water, and also create some by-products we're pretty fond of as well.

Photosynthesis: Crash Course Biology #8

Hank and his brother John discuss heredity via the gross example of relative ear wax moistness.

Heredity: Crash Course Biology #9

Hank introduces us to that wondrous molecule deoxyribonucleic acid - also known as DNA - and explains how it replicates itself in our cells.

DNA Structure and Replication: Crash Course Biology #10

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

DNA, Hot Pockets, & The Longest Word Ever: Crash Course Biology #11

Hank describes mitosis and cytokinesis - the series of processes our cells go through to divide into two identical copies.

Hank gets down to the nitty-gritty about meiosis, the special type of cell division that is necessary for sexual reproduction in eukaryotic organisms.

Meiosis: Where the Sex Starts - Crash Course Biology #13

Hank guides us through the process of natural selection, the key mechanism of evolution.

Natural Selection - Crash Course Biology #14

Hank explains speciation - the evolutionary process by which new biological species arise - in terms of finches, ligers, mules, and dogs.

Speciation: Of Ligers & Men - Crash Course Biology #15

Hank discusses the process by which organisms grow and develop, maintaining that, in the end, we're all just tubes.

Animal Development: We're Just Tubes - Crash Course Biology #16

Hank introduces us to the relatively new field of evolutionary developmental biology, which compares the developmental processes of different organisms to determine their ancestral relationship and to discover how those processes evolved.

Evolutionary Development: Chicken Teeth - Crash Course Biology #17

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

Population Genetics: When Darwin Met Mendel - Crash Course Biology #18

Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

Taxonomy: Life's Filing System - Crash Course Biology #19

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

Evolution: It's a Thing - Crash Course Biology #20

Hank introduces us to comparative anatomy, which studies the similarities and differences in animal anatomy to support the theory of evolution and the shared ancestry of living things.

Comparative Anatomy: What Makes Us Animals - Crash Course Biology #21

Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses, and squid.

Simple Animals: Sponges, Jellies, & Octopuses - Crash Course Biology #22

Hank continues our exploration of animal phyla with the more complexly organized Annelida and Arthropoda, and biography on insects.

Complex Animals: Annelids & Arthropods - CrashCourse Biology #23

Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as Chordata.

Chordates - CrashCourse Biology #24

Hank and his cat Cameo help teach us about animal behavior and how we can discover why animals do the things they do.

Animal Behavior - Crash Course Biology #25

Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body.

The Nervous System - CrashCourse Biology #26

Hank takes us on a trip around the body - we follow the circulatory and respiratory systems as they deliver oxygen and remove carbon dioxide from cells, and help make it possible for our bodies to function.

Circulatory & Respiratory Systems - CrashCourse Biology #27

Hank takes us through the bowels of the human digestive system and explains why it's all about surface area.

The Digestive System: Crash Course Biology #28

Hank takes us on the fascinating journey through our excretory system to learn how our kidneys make pee.

The Excretory System: From Your Heart to the Toilet - CrashCourse Biology #29

Hank introduces us to the framework of our bodies, our skeleton, which apart from being the support and protection for all our fleshy parts, is involved in many other vital processes that help our bodies to function properly.

The Skeletal System: It's ALIVE! - CrashCourse Biology #30

Hank tells us the story of the complicated chemical dance that allows our skeletal muscles to contract and relax.

Big Guns: The Muscular System - CrashCourse Biology #31

Hank tells us about the team of deadly ninja assassins that is tasked with protecting our bodies from all the bad guys that want to kill us - also known as our immune system.

Your Immune System: Natural Born Killer - Crash Course Biology #32

Hank fills us in on the endocrine system - the system of glands that produce and secrete different types of hormones directly into the bloodstream to regulate the body's growth, metabolism, and sexual development & function.

Great Glands - Your Endocrine System: Crash Course Biology #33

Hank lets us in on the meaning of life, at least from a biological perspective - it's reproduction, which answers the essential question of all organisms: how do I make more of myself? So, sex, how does it work?

The Reproductive System: How Gonads Go - CrashCourse Biology #34

Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most abundant organisms on Earth.

Old & Odd: Archaea, Bacteria & Protists - CrashCourse Biology #35

Hank introduces us to nonvascular plants - liverworts, hornworts & mosses - which have bizarre features, kooky habits, and strange sex lives. Nonvascular plants inherited their reproductive cycle from algae, but have perfected it to the point where it is now used by all plants in one way or another.

The Sex Lives of Nonvascular Plants: Alternation of Generations - Crash Course Biology #36

Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and their secret is also their defining trait: conductive tissues that can take food and water from one part of a plant to another part.

Vascular Plants = Winning! - Crash Course Biology #37

Hank gets into the dirty details about vascular plant reproduction: they use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot different compared to the way it did back in the Ordovician swamps.

The Plants & The Bees: Plant Reproduction - CrashCourse Biology #38

Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web.

Fungi: Death Becomes Them - CrashCourse Biology #39

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does.
