Human Body Systems Study Guide

Front

What is the main function of the circulatory system?

Back

The circulatory system is responsible for transporting blood, nutrients, oxygen, carbon dioxide, and hormones throughout the body.

Front

What role do white blood cells (WBC) play in the immune system?

Back

White blood cells (WBC) are crucial for fighting infections and protecting the body against foreign invaders.

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 through the walls of the small intestine.

Front

What is the relationship between the cardiovascular system and the digestive system?

Back

The cardiovascular system transports absorbed nutrients from the digestive system to cells throughout the body.

Front

What is the primary function of the excretory system?

Back

The excretory system removes waste products and excess substances from the body, helping to maintain homeostasis.

Front

How do the excretory and cardiovascular systems interact?

Back

The excretory system cleans the blood by filtering waste through the kidneys, which are part of the excretory system.

Front

What is the role of the lymphatic system in fighting infections?

Back

The lymphatic system helps to transport white blood cells and remove toxins and waste from the body.

Front

How do the digestive and excretory systems work together?

Back

They work together indirectly; the digestive system absorbs nutrients and water, while the excretory system removes excess water and waste.

Front

What is a hydraulic system and how is it similar to the cardiovascular system?

Back

A hydraulic system uses fluid to transmit force, similar to how the cardiovascular system uses blood to transport nutrients and oxygen.

Front

What happens when the excretory system is not functioning properly?

Back

If the excretory system fails, waste products can build up in the blood, affecting the cardiovascular system and overall health.
