Circulatory
This organ pumps oxygenated blood to the body.
Heart
The primary function of this pair of spongy, concept shaped organs is to perform gas exchange.
The Lungs.
First site of mechanical and chemical digestion.
The Mouth.
Command center of the nervous System, protected by the skull, includes the brain and spinal cord.
Central Nervous System (CNS).
A student is sick with a severe cough and shortness of breath. The doctor diagnoses him with pneumonia, an infection affecting the lungs. Which organ system is involved?
Respiratory System.
This blood vessel carries deoxygenated blood to the heart.
Vein
Organ that you can fill when you gently press the front of your neck. Aka the windpipe.
The trachea.
Primary digestive organ where food is mixed with acid and enzymes.
The stomach.
Bundle of nerve tissue, protected by the vertebrae, transmits messages between the brain and rest of the body.
Spinal Cord.
Your body cannot absorb nutrients like glucose and proteins into your blood stream. Which organ system is affected?
Digestive System (Small Intestines).
This blood vessel carries oxygenated blood away from the heart.
Artery.
Microscopic, air sac structures where diffusion of Oxygen and CO2 happens in the lungs.
The Alveoli.
This type of protein speeds up reactions, such as breaking down food molecules during digestion.
Enzyme.
The Nerves.
A person suffers a stroke because blood flow was blocked in the brain. What organ system is affected?
Nervous System
The smallest blood vessel where gas exchange happens.
Capillaries.
Essential process in the lungs where oxygen is diffused into the capillary and carbon dioxide is diffused into the alveoli.
Gas Exchange.
Accessory organ that produces digestive enzymes and hormones to regulate blood sugar.
Pancreas.
The three main functional types of these nerve cells are sensory, interneurons and motor.
Neurons.
The Liver (Digestive System).
Yellowish fluid that has nutrients, hormones, and waste products.
Plasma.
After the trachea splits, the air next travels through two main tubes, one leading to each lung called:
Bronchi.
Hormones that control blood sugar levels.
Insulin and Glucagon.
Branch-like extensions of a neuron that receives messages from other neurons.
Dendrites.
When you start exercising, your nervous System increases your heart rate while your respiratory system increases breathing rate, all to mantain this steady internal state called:
Homeostasis!
