Exam III Bio II

Structure and Function

QuestionAnswer
What are common problems faced by animals? Getting oxygen, food, getting rid of waste, and performing movement.
What does anatomy refer to? Structure.
What does physiology refer to? Function.
What are some restrictions on animal structure? Environment, gravity with mass, evolutionary history, convergent evolution.
What are tissues? Collective groups of tissues with the same structure and function.
What are the four main tissue groups? Epithelial, connective, muscular, nervous.
What is epithelial tissue? Tightly packed sheets of cells with many intercellular tight junctions.
What are functions of epithelial tissue? To cover organs, body cavities, and the outside of the body. They protect organisms from infection and fluid loss.
What are functions of glandular epithelial tissues? They perform absorption and secretion. They are present in the lumen of the digestive tract and in the mucus membranes of the lungs.
What are the different types of epithelial tissues? Simple, stratified, pseudo stratified, squamous, cuboidal, and columnar.
What is the function of connective tissue? To bind and support other tissues.
What is the structure of connective tissue? Cells are scattered with an extensive extracellular matrix. They are secreted by other cells and are made up of fibroblasts and macrophages.
What matrix proteins exist in connective tissues? Collagen. It is nonelastic and keeps skin on the bones.
What are elastic fibers? Elastin, returns skin to where it should.
What are reticular fibers? They are thin and branched collagen fibers that connects connective tissues to other tissues.
What are the different types of connective tissue in vertebrates? Loose connective tissue, adipose, fibrous. cartilage, bone, and blood.
What are the different types of muscle tissue? Muscle fibers (long cells), contracting units (myofibrils made up of actin and myosin), skeletal, cardiac, and smooth.
What makes up nervous tissues? Neurons.
What are some examples of nervous tissue? Brain tissue, the spinal chord, and nerve innervations.
What makes up organs and organ tissues? Multiple tissue layers.
What tissue layers make up the stomach? Epithelial lumen, connective (with blood and nerves), smooth muscle layer, and more connective tissue.
What is the function of mesentery? They support organs in cavities.
What makes up the mesentery tissue? Sheet of connective tissue in the abdominal and thoracic cavities.
What is the function of organ systems? To perform the whole job, organs perform a piece of the process. All organ systems rely on one another.
What are the 3 major organ systems? The digestive tract, the circulatory system, and the nervous system.
What are bioenergetics? The study of the flow of energy in an animal.
How do animals get their energy? Ingesting organic molecules (broken down with enzymes, absorbed into the cells, and produce ATP). Extra molecules used for biosynthesis for growth, repair, storage, to make gametes.
How are ingested molecules converted to various products? By using the carbon backbones in the Krebs cycle.
How is metabolic rate measured? It is measured in calories. It measures heat or in C)2 produced for oxygen consumed.
What are the bioenergetic strategies for endotherms? They have a relatively constant internal temp, have high activity for long durations, and use high amounts of energy.
What are the bioenergetic strategies for exotherms? They use external heat sources, and exert low amount of energy (reptiles, amphibians, and most fish).
How are metabolic rate and size related? The larger the animal, the lower the calories needed per gram likely from heat retention.
What is the basal metabolic rate in endotherms? The calories consumed while at rest. 1300-1800 calories for humans.
What is the standard metabolic rate for endotherms? Changes with temp, increased by activity (long term activity requires high respiration rates for cellular ATP production.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
