What are the main components of blood? Blood's main components are red blood cells, white blood cells, platelets, and plasma.
How does the nephron function in the urinary system? The nephron, the functional unit of the kidney, filters blood to form urine, reabsorbing essential nutrients and excreting waste products.
What is the role of the autonomic nervous system? The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, respiratory rate, and reflexes, through its sympathetic and parasympathetic divisions.
What are the main functions of the integumentary system? The integumentary system serves as a protective barrier, regulates body temperature, and provides sensory information through the skin, hair, nails, and associated glands.
What is the significance of the blood-brain barrier.? The blood-brain barrier is a selective permeability barrier that protects the brain from potentially harmful substances in the bloodstream while allowing essential nutrients to pass through.
What are the primary hormones secreted by the thyroid gland? The thyroid gland primarily secretes thyroxine (T4), triiodothyronine (T3), and calcitonin.
How does oxygen travel in the blood? Oxygen molecules attach to hemoglobin in red blood cells, forming oxyhemoglobin, which is carried to body tissues.
