Question | Answer |
---|---|
Stomach | Food that is eaten breaks down through a process of combining acids with the food and muscles mixing the two together.. |
Liver | creates bile (another form of acid) which combines with the digested food in the small intestine to further break down food so that it can be absorbed by the villi in the small intestine. |
Pancreas | sends chemicals to your small intestine to further break down your food |
Small intestine | This is where food is absorbed into the blood stream through the villi and the capillaries. |
Large intestine | This is where excess water and salts are removed from the food that was not absorbed into the body. All the water and salts removed are sent to the bladder and the remaining food is stored in the colon, ready for removal. |
Bladder | Excess water, salts, and cell waste are stored here until it is full then your body sends a signal to rid the waste by going to the bathroom. |
Skin | 1. Protects the body from the outside world. 2. Helps to keep the body at a constant temperature (Regulate) 3.Contains nerve cells that send information to the brain and let you know when you feel something in your outside environment. |
Lungs | Your body exchanges gasses here. Oxygen is taken into the body and transported to every cell and Carbon Dioxide (A cell waste) is pushed out of the body. |
Kidney | A pair of organs that clean the blood by filtering out wastes and control the amounts of water, salts and vitamins in the blood. |
Brain | Control center of the body. |
Ovaries | The female reproductive organs, they produce eggs. |
Testes | The male reproductive organs, they produce sperm. |
Heart | A muscular organ that pumps blood throughout the body. |
Skeleton | 1. Supports the body and gives it structure. 2. Protects vital organs throughout the body. 3. Works with the nervous system and muscular system to give humans the ability to move. |
Know what triggers the brain to send a message for your body to breathe. | A buildup of carbon dioxide in the blood. |
Where are the capillaries in the lungs found and what are their function? | Surrounding the air sacs. This is where the blood flows around the air sacs and carbon dioxide is traded for fresh oxygen. |
How does food travel from your mouth to your stomach? | It travels down the esophagus to the stomach. Small rings of muscle contract in a pattern in order to squeeze the food down the throat. As each muscle contracts it pushes the food lower and lower down the esophagus until it reaches the stomach. |
Where are the villi found and what is their job? | Found inside the small intestine, their job is to provide more surface area for the absorption of nutrients into the blood stream through the capillaries. |
Circulatory system | moves food, water, vitamins, and enzymes to all cells in the body and carries waste away. (heart, blood vessels, and blood) |
Nervous system | Controls the flow of information and instructions around the body. (brain, spinal cord, nerves) |
Skeletal system | Supports the body, makes motion possible (with the muscles), and protects organs from damage. |
Urinary system | Removes excess water and cell waste from the body (kidneys, bladder, and urethra) |
Digestive system | Breaks down food into chemicals that can be absorbed by the body. (mouth, esophagus, stomach, and intestines) |
Respiratory system | Responsible for bringing air (oxygen) to the lungs for absorption into the blood and for removing carbon dioxide from the body. (trachea, bronchi, bronchioles, and air sacs) |
Plasma | all other parts of the blood, food, water, enzymes, and cell waste travel around the body in the plasma. |
Red blood cells | carries oxygen to all cells in the body and takes carbon dioxide away. |
White blood cells | protect your body from anything that does not have your DNA in it. Multiplies to fight off infections and foreign materials. |
Platelets | sticky cells that act as temporary band-aids in order to stop bleeding and repair wounds. |
How do the urinary and circulatory systems work together? | In the kidneys, they clean the blood by filtering wastes out if it. |
Tropism | the movement of a plant due to an outside stimulus. |
Gravitropism | The growth of a plant or plant part in relation to the pull of gravity. |
Phototropism | A plant’s reaction to a source of light. |
Phototropism | A plant’s growth in response to touching an object. |
What factors influence the rate of growth in a plant? | DNA and the outside environment. |
Asexual Reproduction | one parent, one set of DNA, offspring are a clone of the parent plant. |
Sexual Reproduction | two parents, two half sets of DNA combine to make one set, A combination of characteristics of both parents. |
Monocot | 1. One cotyledon (Food storage) 2. Most have parallel veins in their leaves. 3. Most have a fibrous root system |
Dicot | 1. Two cotyledons (Food storage). 2. Most have branching veins in their leaves. 3. Most have a tap root system. |
Stamen | male part of the plant, the pollen that contains the sperm is found on the end called an anther. |
Pistil | Female part of the plant, eggs are found in the ovaries at the bottom. |
Petal | Colorful leaves that surround the stamen and pistil, used to attract pollinators. |
Sepal | A protective layer of leaf-like structures that surround the flower bud before it opens. |
Know the process of pollination. | Pollination is the process of moving the pollen from the stamen to the pistil. |
Where does most water enter a plant? Be specific. | Root hairs |
Know the differences between a woody stem and a soft stem. | Woody stems have much more xylem tubes than soft stems making them more rigid and giving them the ability to grow taller. |
Xylem | Tubes in vascular plants that carry water and other materials. |
Phloem | Tubes in vascular plants that carry sugar away from the leaves. |
Epidermis | The outer layer of flat cells in a leaf. |
Chloroplasts | The green part of a plant cell that uses the energy in sunlight to turn water and carbon dioxide into oxygen and sugar. |
Know the written formula (process) of photosynthesis | carbon dioxide + water (with nutrients) + sunlight energy = (turns into) oxygen + sugar |
Be able to list and explain two types of asexual reproduction in plants. | Runners – To reproduce by growing new plants on long stems or roots called runners.(Strawberries and grass) Budding - Little buds form on the plant and drop off to grow as separate plants. (Duckweed) |
Be able to explain why plants have more sugar in them during daytime than at night. | Plants use sunlight to energize chloroplasts and make more food than they need food, so they store it. At night there is no sun so they can’t make food and use the stored food made during the day. |
Be able to list at least four ways pollen can be transferred for pollination to occur. | Birds, bats, insects, wind, rain, and human interaction. |
Leaf | Leaves produce food for the plant through a process called photosynthesis. They absorb sunlight for use by the chloroplasts. They take in carbon dioxide and release oxygen. |
Stem | Connect roots to leaves. provide a transportation system for water and sugar within the plant. Give the plant support and structure. |
Root | Anchor the plant to the ground. Absorb water (and nutrients) from the soil. Store excess sugar for later use by the plant. |
