✔️✔️ Distal means farther from the point of attachment.
What is the integumentary system?
✔️✔️ The integumentary system includes skin, hair, and nails that protect the body.
What is the skeletal system?
✔️✔️ The skeletal system provides support, protection, and structure for the body.
What is the function of muscles?
✔️✔️ Muscles produce movement and help maintain posture.
What is the nervous system responsible for?
✔️✔️ The nervous system controls and coordinates body activities.
What is a feedback loop?
✔️✔️ A feedback loop is a system that regulates homeostasis through responses to changes.
What is negative feedback?
✔️✔️ Negative feedback is a process that reverses a change to maintain stability.
What is positive feedback?
✔️✔️ Positive feedback is a process that amplifies a change until a specific event occurs.

,What is an atom?
✔️✔️ An atom is the smallest unit of an element that retains its properties.
What is a molecule?
✔️✔️ A molecule is formed when two or more atoms bond together.
What is an ion?
✔️✔️ An ion is an atom or molecule with a net electrical charge.
What is a proton?
✔️✔️ A proton is a positively charged particle in the nucleus of an atom.
What is a neutron?
✔️✔️ A neutron is a neutral particle found in the nucleus of an atom.
What is an electron?
✔️✔️ An electron is a negatively charged particle that moves around the nucleus.
What is a chemical bond?
✔️✔️ A chemical bond is a force that holds atoms together in molecules.
What is a covalent bond?
✔️✔️ A covalent bond is formed when atoms share electrons.
What is an ionic bond?
✔️✔️ An ionic bond is formed when electrons are transferred between atoms.
What is diffusion?
✔️✔️ Diffusion is the movement of particles from high concentration to low concentration.
What is osmosis?
✔️✔️ Osmosis is the diffusion of water across a semipermeable membrane.
What is active transport?
✔️✔️ Active transport is the movement of substances using energy against a concentration
gradient.
What is passive transport?
✔️✔️ Passive transport is movement of substances without energy use.
What is metabolism?
✔️✔️ Metabolism is all chemical reactions occurring in the body.
3
, What is catabolism?
✔️✔️ Catabolism is the breakdown of complex molecules into simpler ones releasing energy.
What is anabolism?
✔️✔️ Anabolism is the building up of complex molecules from simpler ones using energy.
What is cytoplasm?
✔️✔️ Cytoplasm is the jelly-like substance inside the cell where organelles are found.
What is the nucleus?
✔️✔️ The nucleus is the control center of the cell containing DNA.
What is the cell membrane?
✔️✔️ The cell membrane is a protective barrier that controls what enters and leaves the cell.
What are mitochondria?
✔️✔️ Mitochondria are organelles that produce energy for the cell.
What are ribosomes?
✔️✔️ Ribosomes are structures that synthesize proteins.
What is DNA?
✔️✔️ DNA is genetic material that carries instructions for cell function and inheritance.
What is RNA?
✔️✔️ RNA helps in protein synthesis using genetic instructions from DNA.
What is epithelial tissue?
✔️✔️ Epithelial tissue covers body surfaces and lines organs.
What is connective tissue?
✔️✔️ Connective tissue supports, binds, and protects other tissues.
What is muscle tissue?
✔️✔️ Muscle tissue enables movement of the body and internal organs.
What is nervous tissue?
✔️✔️ Nervous tissue transmits electrical signals for communication.
What is the heart?
✔️✔️ The heart is a muscular organ that pumps blood throughout the body.
What is blood?
✔️✔️ Blood is a fluid connective tissue that transports oxygen, nutrients, and waste.
