1) What makes up your body's cells and how do they function? a) They all look identical and perform the same functions. b) They don't carry DNA but instead rely on the organ's instructions. c) They carry your entire DNA code but use specific parts depending on the cell's function. d) They operate independently without interaction with other cells. 2) How are organ systems organized and how do they work? a) Each organ system operates completely independently without influencing others. b) Organ systems are made of organs and work collaboratively as a team, not in isolation. c) Organs are made directly from DNA and have no connection to cells. d) Only two systems in the body collaborate at a time. 3) What is the primary function of the circulatory system? a) Digesting food to absorb nutrients. b) Producing hormones to regulate growth. c) Eliminating metabolic wastes through urine. d) Transporting blood to carry gases like oxygen and carbon dioxide, and nutrients throughout the body. 4) Which vessels typically carry blood away from the heart? a) Arteries b) Veins c) Capillaries d) Lymph vessels 5) What is the primary role of the digestive system? a) Filtering metabolic wastes from the blood. b) Breaking down food and absorbing nutrients for the body to use. c) Producing red blood cells in bone marrow. d) Controlling body temperature through sweating. 6) What do hormones secreted by the endocrine system do? a) Provide structural support to muscles and bones. b) Transport oxygen through the body via blood. c) Detect sensory information like touch and pain. d) Act as messengers that bind to targets and trigger specific actions. 7) Which of these is NOT a major function of the excretory system? a) Digesting food to absorb nutrients b) Maintaining osmotic balance by regulating water and solutes c) Ridding the body of metabolic wastes like urea d) Involving organs such as kidneys and bladder 8) What layers are part of the integumentary system (skin)? a) Mucosa, serosa, and pleura b) Endocardium, myocardium, and epicardium c) Epidermis, dermis, and hypodermis d) Periosteum, endosteum, and marrow 9) How does the lymphatic and immune system protect the body? a) By producing movement through muscle contractions. b) By transporting oxygen in the bloodstream. c) By creating hormones to regulate growth and stress. d) By collecting and filtering lymph and targeting pathogens using white blood cells and antibodies. 10) What are the three major types of muscle tissue in the muscular system? a) Voluntary, involuntary, and reflexive b) Skeletal, smooth, and cardiac c) Striated, non-striated, and striped d) Fast-twitch, slow-twitch, and intermediate 11) What is the role of alveoli in the respiratory system? a) They are sites of gas exchange between oxygen and carbon dioxide in the lungs. b) They transport air from the mouth to the lungs. c) They produce mucus to trap dust and pathogens. d) They control the rate of breathing by sending nerve signals. 12) How do the skeletal and muscular systems work together in body movement? a) Bones send electrical signals to muscles to cause contraction. b) Muscles pump blood through bones to facilitate movement. c) Muscles contract to move bones, which provide structural support and protection. d) Bones produce hormones to stimulate muscle growth directly.
