Human Anatomy and Physiology-1

What are the three types of muscle tissue?

• Red, White, Blue

• Tendons, Ligaments, Cartilage

• Skeletal, Cardiac, Smooth

• Epithelial, Connective, Nervous

Describe the main functions of the human skeletal system.

• Respiration and gas exchange

• Hormone production and regulation

• The main functions of the human skeletal system are support, protection, movement, blood cell production, and mineral storage.

• Digestion and nutrient absorption

What is the structure of the heart and its main components?

• The heart consists of four chambers (right atrium, right ventricle, left atrium, left ventricle), valves (tricuspid, pulmonary, mitral, aortic), and major blood vessels (aorta, vena cavae, pulmonary arteries, veins).

• The heart is made up of two main components: the atria and the ventricles.

• The heart contains only one valve and no major blood vessels.

• The heart has three chambers: left atrium, left ventricle, and right ventricle.

How does oxygen exchange occur in the respiratory system?

• Oxygen exchange occurs in the alveoli of the lungs through diffusion.

• Oxygen exchange happens in the stomach during digestion.

• Oxygen is absorbed directly through the skin in the respiratory system.

• Oxygen exchange occurs in the trachea through active transport.

What are the primary functions of the nervous system?

• Regulating body temperature

• Producing hormones

• The primary functions of the nervous system are sensory input, information processing, and motor output.

• Digesting food

Outline the main processes involved in digestion.

• Absorption, filtration, respiration, and secretion.

• Mechanical breakdown, synthesis, storage, and excretion.

• The main processes involved in digestion are ingestion, mechanical digestion, chemical digestion, absorption, and elimination.

• Ingestion, fermentation, detoxification, and hydration.

Define the term 'homeostasis' in relation to human physiology.

• Homeostasis is the fluctuation of body temperature during exercise.

• Homeostasis refers to the process of aging in the human body.

• Homeostasis is the maintenance of a stable internal environment in the human body.

• Homeostasis is the body's ability to grow and develop over time.

What is the role of red blood cells in the body?

• Red blood cells produce hormones in the body.

• Red blood cells transport oxygen and carbon dioxide in the body.

• Red blood cells are responsible for immune response.

• Red blood cells help in digestion of food.

Explain the difference between voluntary and involuntary muscles.

• Voluntary muscles are always relaxed, while involuntary muscles are always contracted.

• Voluntary muscles are controlled consciously, while involuntary muscles function automatically.

• Voluntary muscles are found in the heart, while involuntary muscles are in the limbs.

• Involuntary muscles are controlled by the brain, while voluntary muscles are not.

What are the major bones in the human body?

• humerus, radius, scapula

• skullcap, jawbone, ankle

• Skull, vertebrae, ribs, sternum, humerus, radius, ulna, femur, patella, tibia, fibula.

• clavicle, scapula, pelvis
