What is the primary function of the muscular system?

• Providing structural support to the body.

• Transporting oxygen in the blood.

• Facilitating movement of the body.

• Regulating body temperature.

Name the three types of muscle tissue found in the human body.

• Skeletal muscle, Cardiac muscle, Smooth muscle

• Cartilage

• Ligaments

• Tendons

What are the main components of the nervous system?

• Somatic nervous system and immune system

• Autonomic nervous system (ANS) and endocrine system

• Central nervous system (CNS) and peripheral nervous system (PNS)

• Cerebral cortex and spinal cord

How does the central nervous system differ from the peripheral nervous system?

• The CNS consists of nerves; the PNS consists of the brain and spinal cord.

• The CNS is responsible for reflex actions; the PNS controls voluntary movements.

• The CNS processes information; the PNS connects the CNS to the rest of the body.

• The CNS connects the body to the brain; the PNS processes information.

What is the role of the heart in the cardiovascular system?

• The heart's role is to pump blood throughout the body.

• The heart filters toxins from the blood.

• The heart produces hormones that regulate blood pressure.

• The heart stores oxygen for the body.

Describe the pathway of blood flow through the heart.

• Right atrium → Right ventricle → Lungs → Left atrium → Left ventricle → Aorta

• Right atrium → Left ventricle → Lungs → Right ventricle → Aorta → Left atrium

• Left atrium → Right atrium → Aorta → Left ventricle → Lungs → Right ventricle

• Right ventricle → Aorta → Lungs → Left atrium → Right atrium → Left ventricle

What are the primary functions of the respiratory system?

• Production of hormones

• Regulation of body temperature

• Digestion of food

• The primary functions of the respiratory system are gas exchange, regulation of blood pH, and protection against pathogens.

Explain the process of gas exchange in the lungs.

• Gas exchange happens in the diaphragm, which regulates breathing rates.

• Gas exchange occurs in the trachea, where oxygen is filtered from the air.

• Carbon dioxide is absorbed into the blood while oxygen is released in the bronchi.

• Gas exchange in the lungs occurs in the alveoli, where oxygen is absorbed into the blood and carbon dioxide is released.

What are the main organs involved in the digestive system?

• Mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder.

• Heart, lungs, kidneys, bladder

• Brain, spinal cord, nerves, skin

• Spleen, gallbladder, appendix, thyroid

How does the skeletal system support the body?

• The skeletal system supports the body by providing structure, protection, and facilitating movement.

• The skeletal system generates energy for the body.

• The skeletal system absorbs nutrients from food.

• The skeletal system regulates body temperature.
