erythropoietin to stimulate red blood cell production. ✔️✔️



What is the function of the mast cells in the immune response?

Mast cells release histamine and other chemicals that play a role in inflammation and allergic responses.
✔️✔️



How does the small intestine aid in nutrient digestion and absorption?

The small intestine contains enzymes that break down food into nutrients, and its villi and microvilli
increase surface area for efficient nutrient absorption. ✔️✔️



What is the function of the epidermis in protecting the skin?

The epidermis acts as a barrier to prevent the entry of pathogens, regulate water loss, and protect from
UV radiation. ✔️✔️



What is the role of the blood-brain barrier?

The blood-brain barrier protects the brain by restricting the passage of harmful substances from the
bloodstream into the brain tissue. ✔️✔️

,How does the body maintain homeostasis of blood pH?

The body maintains blood pH by regulating levels of carbon dioxide through respiration and by using
buffers to neutralize excess acids. ✔️✔️



What is the function of the liver in digestion and metabolism?

The liver produces bile to help digest fats and processes nutrients absorbed from the small intestine,
storing glucose as glycogen and detoxifying harmful substances. ✔️✔️



What is the function of the medulla oblongata in the brain?

The medulla oblongata controls vital functions such as heart rate, breathing, and blood pressure.
✔️✔️



How do the lungs help maintain proper acid-base balance?

The lungs regulate the body’s pH by removing excess carbon dioxide from the blood, which helps
prevent the blood from becoming too acidic. ✔️✔️



What is the function of the synapse in nerve communication?

The synapse is the gap between neurons where neurotransmitters transmit signals from one neuron to
another, allowing communication within the nervous system. ✔️✔️



What is the primary function of the gallbladder?

The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to
aid in the digestion of fats. ✔️✔️



How does the immune system respond to infection?

The immune system identifies pathogens through antibodies and white blood cells, which then work to
neutralize and destroy the invaders. ✔️✔️



What is the function of the cerebrum in the brain?

The cerebrum controls higher-level functions such as thought, memory, decision-making, and voluntary
movement. ✔️✔️

, What is the role of the large intestine in the absorption of water?

The large intestine absorbs water and electrolytes from the indigestible food, turning it into solid waste
for elimination. ✔️✔️



What is the role of the pancreas in regulating blood sugar levels?

The pancreas secretes insulin to lower blood sugar levels and glucagon to raise them, maintaining stable
glucose levels in the blood. ✔️✔️



What is the function of the pituitary gland in the endocrine system?

The pituitary gland controls other endocrine glands by releasing hormones that regulate growth,
metabolism, and reproductive functions. ✔️✔️



What is the role of the cilia in the respiratory system?

Cilia in the respiratory system move mucus and trapped particles upward, helping to clear the airways
and protect the lungs from infection. ✔️✔️



How does the immune system distinguish between self and non-self cells?

The immune system uses major histocompatibility complex (MHC) molecules to recognize self-cells and
distinguish them from foreign cells. ✔️✔️



What is the function of the iliac arteries in the circulatory system?

The iliac arteries supply blood to the lower limbs and pelvic organs, branching off from the aorta.
✔️✔️
