Homeostasis
The process of maintaining a stable internal environment is called
What is "Homeostasis"?
This body system brings oxygen into the body
What is the "Respiratory System"?
This process do cells use to release energy from food
What is "Cellular Respiration"?
This nutrient provides the body with quick energy during exercise
What is "Carbohydrates"?
This process moves water across a cell membrane from an area of high water concentration to low water concentration
What is "Osmosis"?
During a marathon, sweating helps regulate this body condition
What is "Body Temperature"?
This organ pumps blood throughout the body
What is the "Heart"?
This gas is required for aerobic respiration
What is "Oxygen"?
Hydration is important during a marathon because it
What is "prevent dehydration and maintain body functions"?
This structure controls what enters and leaves the cell during osmosis
What is "Cell Membrane"?
This body system helps transport oxygen and nutrients during exercise
What is the "Circulatory System"?
This system removes waste products from the body
What is the "Excretory System"?
This molecule provides quick energy to cells
What is "ATP"?
This nutrient helps repair muscles after exercise
What is "Protein"?
A cell is placed in salt water and loses water, the outside solution is described as this type of solution
What is a "Hypertonic Solution"?
When runners become dehydrated, the balance of water in the body is disrupted. This balance is called
What is "Water Balance"?
This type of muscle is found in the heart
What is "Cardiac Muscle"?
When oxygen is low during intense exercise, this type of respiration may occur
What is "Anaerobic Respiration"?
During exercise heart rate increases due to
What is "Higher demand for Oxygen and Nutrients?"
This body organ plays the largest role in maintaining water balance and osmoregulation in humans
What are the "Kidneys"?
This type of feedback mechanism helps keep body conditions stable during exercise
What is "Negative Feedback"?
These two body systems work closely together to deliver oxygen to cells during a marathon
What are the "Respiratory and Circulatory Systems"?
This waste product can build up in muscles during anaerobic respiration
What is "Lactic Acid"?
This is one benefit of endurance training
What is "Improved Cardiovascular Fitness"?
During osmoregulation, this hormone helps the kidneys reabsorb more water when the body is dehydrated
What is "ADH" (antidiuretic hormone)?
