How does the digestive system work with the cardiovascular system?

Back

The cardiovascular system absorbs nutrients into the bloodstream via capillaries in the small intestine.

Front

In what way is the cardiovascular system similar to a hydraulic system?

Back

Its organs work together to provide services for other body systems, similar to how a hydraulic system uses fluid to fuel other machine systems.

Front

Which body systems are involved in waste removal?

Back

1. Digestive system removes solid wastes. 2. Excretory system removes liquid wastes. 3. Respiratory system removes gaseous waste.

Front

How do the respiratory and cardiovascular systems collaborate to supply oxygen to cells?

Back

CO2 rich blood diffuses out of the circulatory system into the lungs to be exhaled, while O2 diffuses into the bloodstream.

Front

What is the primary function of the muscular system?

Back

The muscular system enables movement of the body and maintains posture.

Front

What is the function of the excretory system?

Back

The excretory system removes liquid wastes from the body.

Front

What is the main purpose of the respiratory system?

Back

The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide.

Front

How does the digestive system contribute to nutrient absorption?

Back

The digestive system breaks down food into nutrients, which are then absorbed into the bloodstream.

Front

What is the role of capillaries in the cardiovascular system?

Back

Capillaries are small blood vessels that facilitate the exchange of oxygen, nutrients, and waste between blood and tissues.
