Answer 1

Each human body system has specific functions: The circulatory system transports substances, the digestive system breaks down food, the endocrine system regulates through hormones, the excretory system removes waste, the muscular system facilitates movement, the nervous system controls bodily functions, the reproductive system produces offspring, the respiratory system exchanges gases, and the skeletal system supports the body.

Step-by-step explanation:

Functions of Human Body Systems

• Circulatory system: Transports blood, nutrients, gases, and wastes. It includes heart, blood vessels, and works with the respiratory, endocrine, and nervous systems.
• Digestive system: Breaks down food into nutrients that the body can absorb, it includes organs from the mouth to the intestines, utilizing digestive enzymes and bacteria for breaking down compounds.
• Endocrine system: Regulates bodily functions through hormones, which are released by glands such as the thyroid and adrenal gland, influencing processes like growth, metabolism, and reproduction.
• Excretory system: Removes waste from the body, primarily involving the kidneys and the urinary system, also includes the lungs and skin as they excrete carbon dioxide and sweat, respectively.
• Muscular system: Allows movement of the body, maintains posture, and generates heat. It includes skeletal muscles, smooth muscles, and cardiac muscles.
• Nervous system: Controls both voluntary actions and involuntary responses, and transmits signals between different parts of the body. It comprises the brain, spinal cord, and nerves.
• Reproductive system: Includes organs involved in producing offspring, such as the testes in the male reproductive system and the ovaries in females.
• Respiratory system: Enables breathing, exchanging oxygen for carbon dioxide waste, involving the lungs and air passages.
• Skeletal system: Provides structure to the body, protects internal organs, and allows movement through the work of bones and joints, often in conjunction with the muscular system.

Answer 2

1. The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides.

2. Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins, minerals, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.

3. Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.

4. Excretory systems regulate the chemical composition of body fluids by removing metabolic wastes and retaining the proper amounts of water, salts, and nutrients. Components of this system in vertebrates include the kidneys, liver, lungs, and skin.

5. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.

6. The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

7. To produce egg and sperm cells.

To transport and sustain these cells.

To nurture the developing offspring.

To produce hormones.

8. The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

9. The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals. The skeletal system is also called the musculoskeletal system.
