How does the circulatory system contribute to maintaining body temperature?
How does the circulatory system contribute to maintaining body temperature?
- By breaking down food and absorbing nutrients.
- By moving blood vessels closer to or further from the skin's surface. (correct)
- By exchanging oxygen and carbon dioxide in the lungs.
- By filtering waste products from the blood.

- Organs are made of organ systems, which are made of tissues, which are made of cells.
- Tissues are made of cells, which form organs, which work together in organ systems. (correct)
- Organ systems are made of cells, which are made of tissues, which are made of organs.
In what way does the excretory system assist the respiratory system?
In what way does the excretory system assist the respiratory system?
- By removing carbon dioxide from the blood, a waste product of cellular respiration. (correct)
- By delivering oxygen to the cells of the respiratory system.
- By breaking down food to provide nutrients for the respiratory system.
- By protecting lungs.

Study Notes
- Large nasal passages and special blood flow enable caribou to warm cold air and retain heat.
- Insects breathe via spiracles, small holes they adjust to regulate airflow.
- Darwin discovered 13 finch species with beaks adapted to various food sources like seeds, fruit, and cactus, demonstrating adaptation.
- Organs consist of tissues, which consist of cells requiring food and oxygen to function, and form systems to perform bodily functions.
Body Systems
- Organ systems are groups of organs performing functions together.
- The circulatory system, consisting of the heart, blood vessels, and blood, transports oxygen, nutrients, and waste while regulating body temperature.
- The respiratory system, which includes the nose, mouth, lungs, and diaphragm, facilitates oxygen and carbon dioxide exchange and balances blood acidity.
- The digestive system, encompassing the mouth, stomach, liver, and intestines, breaks down food for absorption.
- The excretory system, containing the kidneys, bladder, and lungs, removes waste from the blood.
- The integumentary system, which includes the skin, protects the body and perceives touch, pain, and temperature.
- The muscular system, made up of muscles and tendons, facilitates movement of bones and organs.
- The skeletal system, including bones and cartilage, supports the body and protects organs.
- The nervous system, comprising the brain, spinal cord, nerves, and sensory organs, governs body functions and detects changes.
Cell Parts
- Organelles are small components within cells.
- The cell membrane is a thin layer surrounding the cell.
- The cell wall is a rigid exterior layer found in plant cells.
- Cytoplasm is the liquid filling the cell, containing various components.
- The nucleus is a large, dark, round structure located in the cell's center.
- Vacuoles are liquid-filled spaces within the cell.
- Flagella are long tails utilized for cell movement.
- Cilia are short, hair-like structures that eliminate harmful particles.
- Only plant cells have cell walls and chloroplasts.
- Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
- Hyper refers to more, iso means the same, and hypo signifies less.
