What is the primary pigment in red blood cells that carries oxygen?
Answer: Hemoglobin
Hemoglobin is the iron-containing protein in red blood cells that binds and transports oxygen from the lungs to tissues.
Which gland is known as the 'master gland' of the endocrine system?
Answer: Pituitary gland
The pituitary gland is called the master gland because it secretes hormones that regulate many other endocrine glands.
What type of circulation carries deoxygenated blood from the heart to the lungs for oxygenation?
Answer: Pulmonary circulation
Pulmonary circulation carries deoxygenated blood from the right ventricle to the lungs, where gas exchange occurs.
Which immune cell is primarily responsible for destroying virus-infected cells?
Answer: Cytotoxic T lymphocytes (CD8+)
Cytotoxic T cells (CD8+) recognize and kill cells displaying foreign antigens, such as virus-infected cells.
Which connective tissue connects bone to bone at a joint?
Answer: Ligament
Ligaments are fibrous connective tissues that connect bones to other bones, stabilizing joints.
In the vertebrate ear, what structure converts sound vibrations into nerve impulses?
Answer: Cochlea
The cochlea contains hair cells that transduce mechanical sound vibrations into electrical signals sent via the auditory nerve.
What is the main function of the large intestine in the digestive system?
Answer: Water absorption and formation of feces
The large intestine absorbs water and electrolytes from indigestible material, compacting waste into feces for elimination.
