Question

question 7 of 10

which body system is a transporter that transports fats from the digestive system and is involved in the immune system?

lymphatic system
urinary system
endocrine system
cardiovascular system

Explanation:

Identify the key functions described

The question asks for a body system that performs two specific roles:

1. Transports fats absorbed from the digestive system.
2. Is involved directly in the immune system.

Analyze the candidate systems

• Lymphatic system: This system absorbs dietary lipids (fats) from the small intestine via specialized lymphatic capillaries called lacteals. It also houses and transports lymphocytes (white blood cells), playing a central role in the body's immune defense.
• Urinary system: Primarily filters blood to remove waste products and regulate water/electrolyte balance; it does not transport dietary fats or serve as a primary immune system component.
• Endocrine system: Consists of glands that secrete hormones to regulate bodily functions; it is not a direct transporter of dietary fats.
• Cardiovascular system: While it transports many nutrients and oxygen throughout the body, dietary fats are first absorbed into the lymphatic system before entering the bloodstream. The lymphatic system is uniquely characterized by both fat transport (via lacteals) and immune function.

Match with the correct option

The lymphatic system perfectly matches both criteria described in the prompt.

Answer:

• Lymphatic system (Correct answer)
• Urinary system
• Endocrine system
• Cardiovascular system
