Which of the following accurately describes the relationship between different levels of organization in the human body?
Which of the following accurately describes the relationship between different levels of organization in the human body?
- Systems are built from organs, which are made of cells, and tissues support the systems.
- Tissues are collections of similar cells that form organs, which then work together in organ systems. (correct)
- Cells combine to form organ systems, which then differentiate into various tissue types and specialized organs.
- Organs are composed of systems, which in turn are made of tissues, and finally cells.
The lymphatic system is most closely associated with which of the following functions?
The lymphatic system is most closely associated with which of the following functions?
- Defending the body against infection and removing cellular debris. (correct)
- Removing waste products from the blood and regulating electrolyte balance.
- Transporting oxygen and nutrients throughout the body.
- Breaking down food particles for absorption into the bloodstream.
How do the nervous and endocrine systems coordinate to maintain homeostasis in the human body?
How do the nervous and endocrine systems coordinate to maintain homeostasis in the human body?
- The nervous system provides structural support, while the endocrine system facilitates movement.
- The nervous system uses electrical signals for rapid responses, while the endocrine system employs hormones for sustained regulation. (correct)
- The nervous system breaks down food, while the endocrine system absorbs the nutrients.
- The nervous system transports oxygen, while the endocrine system removes carbon dioxide.

Study Notes
- Human body systems are composed of cells, tissues, and organs functioning together.
- Organs cooperate, like the stomach and intestines in digestion.
Major Body Parts
- External parts: head, neck, shoulders, trunk, upper and lower limbs.
- Internal structures: arteries, veins, bones, joints, connective tissue, epithelial tissue, muscles, nerves, organs, and adipose tissue.
Ten Human Body Systems
- The body contains the musculosketal, the cardiovascular, respiratory, lymphatic, nervous, endocrine, integumentary, digestive, urinary, and reproductive systems.
Musculoskeletal System
- Includes bones, joints, ligaments, tendons, cartilage, and muscle, providing support, structure, and movement.
- Can be separated into muscular and skeletal systems.
- Works with the nervous and digestive systems.
Cardiovascular System
- The heart pumps blood through arteries and veins, transporting oxygen and nutrients.
- Dependent on other systems like respiratory, digestive, endocrine, lymphatic, and every tissue, cell, and organ for constant oxygen supply.
Respiratory System
- Includes lungs, nose, pharynx, larynx, trachea, and bronchi, enabling oxygen intake and carbon dioxide expulsion.
- Alveoli in the lungs facilitate oxygen and carbon dioxide exchange with red blood cells.
Lymphatic System
- Also known as the immune system, it defends against infections and clears cellular debris.
- Includes lymph nodes, bone marrow, spleen, thymus, and skin, with immune cells stored and developed in bone marrow, the spleen and thymus.
Nervous System
- A sensory and control system comprising the brain, spinal cord, and neurons.
- The brain (CNS) is the primary control hub, with the spinal cord (CNS) acting as a signal pathway.
- Neurons (PNS) transmit environmental information to the brain and carry signals to organs and tissues.
Endocrine System
- Directs metabolism, growth, and sexual reproduction via hormones.
- Includes thyroid, parathyroid, adrenal glands, pancreas, ovaries, testes, pituitary gland, pineal gland, and hypothalamus.
- Organs are located in the head, neck, and trunk.
- The pancreas regulates blood sugar, adrenal glands regulate response to stress and inflammation, and the parathyroid regulates calcium absorption.
Integumentary System
- Skin protects internal structures and regulates touch, temperature, and waste expulsion.
- Includes skin, nails, and hair.
Digestive System
- Digests and absorbs nutrients using enzymes to break down food into basic components.
- Includes the stomach, small intestines, large intestines, mouth, salivary glands, esophagus, pharynx, pancreas, liver, and gallbladder.
Urinary System
- Excretes waste and regulates water and mineral balance and includes and the bladder, ureter, urethra, and kidneys.
- The kidneys filter waste from the blood and send it to the bladder, which then releases urine via the urethra.
Reproductive System
- Produces gametes (sperm or egg cells).
- Male organs: penis, testes, scrotum, prostate gland.
- Female organs: uterus, ovaries, fallopian tubes, vulva, vagina.
