Cardiovascular System
True or False: Arteries carry oxygen-depleted blood back to the heart
False
True or False
Exhalation is the process of breathing out air.
True
Which body system is responsible for endurance during sports
Cardiovascular system
What organ acts as the pump of the cardiovascular system
The Heart
The Cardiovascular System is a closed system that consists of these three things.
1. The Heart
2. Blood
3. Blood Vessels
Gas exchange occurs here by simple diffusion through the respiratory membrane.
Alveoli (Alveolar sac)
A basketball player jumps for a rebound. What major muscles are helping this movement?
Quadriceps
Calves
Core
What organ is mainly responsible for breathing?
The lungs
One of the functions of the cardiovascular system is to protect the body against what two things?
Disease & Infection
The Normal Respiration Rate at Rest for healthy adults is typically what? (looking for a range)
12 to 20 breaths per minute
Cat cow stretch is a mobility movement for this muscle
Abdominals
What is the main job of the cardiovascular system
To transport oxygen, nutrients, and blood throughout the body.
What is a normal Resting heart rate (looking for a range)
60-100 beats per minute
This Disease is a long-term lung disease that includes chronic bronchitis and emphysema, causing difficulty in breathing due to blocked airflow.
COPD
Chronic
Obstructive
Pulmonary
Disease
This type of muscle is involuntary and helps pump blood throughout the body.
Cardiac Muscle
During exercise, does heart rate increase or decrease? Why?
Increase: The body needs more oxygen and nutrients.
Give three long-term adaptations that occur in the cardiovascular system
1. Cardiac hypertrophy
2. Increased stroke volume
3. Increased max cardiac output
4. Lower resting heart rate
5. Increase in capilliarisation
6. Increase in red blood cells
Give three long-term adaptations that occur in the respiratory system.
1. Increased number of alveoli
2. Increased strength of intercostal muscles
3. INcreased vital capacity
4. Increased strength of diaphragm
Which muscle is the calf muscle that helps lift the heel
Gastrocnemius
Muscles need oxygen to produce (what ) for movement
Energy (ATP)
