Organ Systems
This system contains the heart, blood vessels, and blood and is responsible for transporting materials throughout the body.
What is the cardiovascular or circulatory system?
This muscular organ sits in the mediastinum and is posterior to the sternum.
What is the heart?
In the circulatory system, blood travels away from the heart through these tubes.
What are arteries?
This process describes the movement of air into and out of the lungs.
What is ventilation?
An electric signal is sent telling the body to move your finger to your nose. These systems work to complete this process.
What are the nervouse system and the muscular system?
This system uses electrical and an action potential to control movement, sensation, and rapid responses.
What is the nervous system?
This muscle separates the thoracic and abdominal cavities and is primarily responsible for normal inhalation.
What is the diaphragm?
This tube is between the larynx and the main stem bronchi.
What is the trachea?
During inhalation, the diaphragm contracts, increasing the size of the thoracic cavity and producing this pressure change.
What is a decrease or negative pressure inside the chest cavity?
Outside air is moved inside of the body and absorbed. These systems work to complete this process.
What are the respiratory system and the circulatory system?
This system filters the blood, regulates fluid balance, and removes selected wastes from the body.
What is the urinary system?
These structures are located at the ends of the bronchioles and are surrounded by pulmonary capillaries.
What are the alveoli?
These microscopic vessels connect arterioles and venules and have very thin walls.
What are capillaries?
Oxygen moves from the alveoli into pulmonary capillaries because oxygen moves from an area of higher concentration to an area of lower concentration. Name the process.
What is diffusion?
Nutrients are absorbed then glucose is moved into cells and into storage. These systems work to complete this process.
What are the digestive system and the endocrine system?
This system releases chemical messengers into the bloodstream to regulate the activity of target cells.
What is the endocrine system?
These organs lie in the retroperitoneal cavity and filter the blood.
What are the kidneys?
These tubes carry waste from the kidneys to the urinary bladder.
What are ureters?
At systemic capillaries, this pressure pushes water and dissolved substances out of the bloodstream and toward the tissues.
What is hydrostatic pressure?
Communication is sent through your body to become more alert to a danger and prepare to act. These systems work to complete this process.
What are the nervous system and the endocrine system?
This system returns excess interstitial fluid to the bloodstream and filters that fluid through structures located along its vessels.
What is the lymphatic system?
This gland is located posterior to the stomach and performs functions in both the digestive and endocrine systems.
What is the pancreas?
These tubes supply the myocardium with blood, oxygen, and nutrients.
What are the coronary arteries?
Plasma proteins remaining inside the bloodstream create this pressure, which attracts water toward the systemic capillary.
What is oncotic pressure?
The body returns to homeostasis after being in an acidic state. These systems work to complete this process.
What are the respiratory system and the urinary system?
