Leads to a specific conclusion. Inductive reasoning - correct answer Method of arriving at general principles from specific facts. Conclusion is formed by information that is most likely true Atoms - correct answer The smallest part of an element that still retains all the original properties of the element. They combine to form molecules Molecules - correct answer a chemical bonding of atoms. They combine to form cells!!! Organs - correct answer Two or more tissue types that work together to perform a specific function What are the four types of tissue? - correct answer epithelial, connective, muscular, and nervous Epithelial tissue - correct answer Provides covering or produce secretions. Commonly exists in layers and does not have its own blood supply. Because of this, it depends on nearby capillaries for food and oxygen, via diffusion. What are the two TYPES of epithelial tissue? - correct answer 1. Simple epithelium = One layer of cells. Found in body structures where absorption, secretion, and filtration occur. 2. Stratified epithelium = Multiple layers of cells. Serves as protection What are the three SHAPES of epithelial tissue? - correct answer Squamous, cuboidal, and columnar What body parts are made of connective tissue? - correct answer tendons, ligaments, bones, blood, and adipose (fat). Some connective tissues, such as ligaments, do not have their own blood supply. tendon - correct answer strong connective tissue that attaches muscle to bone Ligament - correct answer strong connective tissue that attaches bone to bone What are the three types of muscle tissue? - correct answer 1. Skeletal = Supports voluntary movements connected to bones in the skeletal system 2. Cardiac = Found in heart. Under Involuntary control 3. Smooth = Found in walls of hollow organs such as intestines, blood vessels, bladder, and uterus. Also under involuntary control Nervous tissue makes up the... - correct answer Brain, spinal cord, and nerves The circulatory system is made up of what? What is its function? - correct answer The heart, blood vessels, and blood. Circulates and distributes various substances throughout the body such as oxygen, hormones, and nutrients from food The digestive system consists of... - correct answer All the organs from mouth to the anus. This includes the esophagus, stomach, small and large intestines, rectum, liver, pancreas, and anus. What is the function of the digestive system? - correct answer Indigestion and breakdown of food. MANUFACTURES ENZYMES that break down food so nutrients can be passed into the blood and then into the body what parts is the small intestine made of, and what is its function? - correct answer The small intestine is made up of the duodenum, jejunum and ileum. It is the site for nutrition absorption. ABSORBS NUTRIENTS What is the function of the colon? - correct answer the colon removes WATER from the waste that remains after absorption by the small intestine. REMOVES WATER What is the function of the liver? - correct answer The liver produces bile that helps break down fats. PRODUCES BILE What is the function of the pancreas? - correct answer The pancreas delivers enzymes to the small intestine that aid in digestion DELIVERS ENZYMES What is the function of the endocrine system? - correct answer The endocrine system controls body functions such as growth and metabolism. It is made up of glands that secrete hormones to the blood, then to organs, then to the rest of the body. what are the glands of the endocrine system? - correct answer the pineal, pituitary, thalamus, hypothalamus, thyroid, thymus, and adrenal glands. PPHATTT what is the integumentary system made up of, and what is its function? - correct answer made up of the skin, mucous membranes, hair, and nails. Protects internal tissues from injury and pathogens. Also waterproofs the body and regulates body temperature. HNMS (like the store H&M) what is the function of the lymphatic system? - correct answer Lymph nodes and lymph vessels carry lymph, Which is a clear fluid rich in antibodies. Houses and transports white blood cells to and from lymph nodes. Returns leaked fluid back into the blood vessels (back into blood). What does the lymphatic system consist of? - correct answer The spleen, thymus, and tonsils. They are all made of lymphoid tissue. Muscular system - correct answer The muscular system consists ONLY of skeletal muscles, as well as tendons and ligaments. The muscular system DOES NOT include cardiac and smooth muscles, which are involuntary What parts does the nervous system consist of, and what is its function? - correct answer The nervous system consists of the brain, spinal cord, and nerves. It is the body's control system. Sensory receptors detect stimuli that can occur both inside and outside the body. What does the reproductive system consist of? - correct answer Testes, penis, ovaries, vagina, and breasts. These organs house hormones that encourage or suppress activities within the body, and they also influence the development of the body. What is the function of the respiratory system? - correct answer The respiratory system keeps the body's cells supplied with oxygen, and it removes CO2 as it is released from cells. Alveoli are tiny air sacks in the lungs through which oxygen and CO2 move in and out of via small blood vessels called arterioles. What are arterioles? - correct answer Arterioles are small blood vessels found in the walls of alveoli which are found in the lungs. Oxygen and CO2 move in and out of these small blood vessels. What does the respiratory system consist of? - correct answer Nasal cavity, pharynx, larynx, trachea, bronchi, and the lungs. What does the skeletal system consists of, and what is its function? - correct answer The skeletal system consists of bones, cartilage, ligaments, and joints. It provides support and protection, and a framework that creates movements (with the help of muscles). What is the function of the urinary system? - correct answer The urinary system helps maintain the water/electrolyte balance within the body. It also regulates the acid-base balance of the blood, and removes all nitrogen-containing waste from the body.
