Cardio Respiratory System Concepts

The video tutorial provides an in-depth look at the cardio respiratory system, focusing on its role in transporting nutrients, oxygen, and waste products. It explains how glucose, amino acids, and oxygen are delivered to cells, and how waste products like CO2 and lactic acid are removed. The tutorial also covers thermoregulation and the processes of vasodilation and vasoconstriction, highlighting their importance during exercise.

What is the primary role of the cardio respiratory system as introduced in the video?

• To regulate body temperature

• To store waste products

• To produce energy

• To transport nutrients and oxygen

Which nutrient is specifically mentioned as being transported by the cardio respiratory system?

• Glucose

• Vitamins

• Minerals

• Proteins

Why is oxygen transported to all cells in the body?

• For photosynthesis

• For aerobic respiration

• For anaerobic respiration

• For digestion

What is a waste product of aerobic respiration that needs to be removed from the body?

• Oxygen

• Hydrogen

• Carbon dioxide

• Nitrogen

How is carbon dioxide transported back to the lungs?

• Dissolved in plasma

• Bound to glucose

• As a solid

• Through the lymphatic system

What is the term used to describe the body's temperature control mechanism?

• Homeostasis

• Metabolism

• Photosynthesis

• Thermoregulation

What happens to the skin during exercise as part of thermoregulation?

• It becomes red

• It becomes dry

• It becomes cold

• It turns blue

What is vasodilation?

• Formation of new blood vessels

• Increase in blood vessel diameter

• Decrease in blood vessel diameter

• Blockage of blood vessels

How does vasoconstriction affect blood flow?

• Decreases blood flow

• Increases blood flow

• Has no effect on blood flow

• Stops blood flow completely

During exercise, where is blood flow increased due to vasodilation?

• To the brain

• To the muscles

• To the liver

• To the skin
