vocab
This process describes the body’s ability to maintain a stable internal environment, such as regulating temperature or blood glucose levels.
What is homeostasis?
This membrane, the largest in the body, is the driest membrane and functions as a protective barrier.
What is the cutaneous membrane?
Nicknamed the “powerhouse” of the cell, this organelle generates ATP through cellular respiration.
What is the mitochondria?
This type of bond forms when one atom donates an electron to another, creating oppositely charged ions that attract.
What is an ionic bond?
The tissue type that you would expect to find on the surface of the body that is subject to friction
What is epithelial tissue?
This field of study focuses on the structure of the body and its parts
What is anatomy?
The layer of a serous membrane that directly covers an organ, such as the heart or lungs.
What is the visceral layer?
Studded with ribosomes, this organelle helps produce proteins that are destined for secretion or insertion into membranes.
What is the rough endoplasmic reticulum (rough ER)?
This bond involves atoms sharing one or more pairs of electrons, as seen in water (H₂O).
What is covalent bond?
This type of connective tissue stores fat and synthesizes blood cells
What is is osseous year?
This branch of biology studies the function of body parts and how they work together.
What is physiology?
The layer of a serous membrane that lines the cavity wall instead of the organ surface.
What is the parietal layer?
This organelle modifies, packages, and ships proteins and lipids, often compared to the “post office” of the cell.
What is the Golgi apparatus?
Though weaker than covalent and ionic bonds, this type of bond is crucial for holding together the two strands of DNA and giving water its unique properties.
What is a hydrogen bond?
The epithelial tissue that is best suited for areas of your skin where diffusion and filtration occur occurs
What is simple squamous?
This branch of anatomy deals with tissues and requires a microscope to study.
What is histology?
This slippery membrane lines body cavities closed to the outside and reduces friction between organs.
What is a serous membrane?
This organelle contains digestive enzymes and is responsible for breaking down waste materials, cellular debris, and invading pathogens.
What is the lysosome?
In this type of covalent bond, electrons are not shared equally, leading to a molecule with partial positive and negative ends.
What is a polar covalent bond?
Found in tendons and ligaments, this connective tissue type is made up of tightly packed collagen fibers for strength and support.
What is dense regular connective tissue?
These biological catalysts speed up chemical reactions by lowering activation energy without being consumed.
What are enzymes?
These are the three major serous membranes of the body: one surrounding the lungs, one enclosing the heart, and one lining the abdominal cavity.
What are the pleura, pericardium, and peritoneum?
Large or polar molecules that cannot cross the plasma membrane freely rely on this process, in which specific carrier or channel proteins help them move down their concentration gradient.
What is facilitated diffusion?
This type of covalent bond occurs when two atoms share electrons equally, such as in O₂ or N₂.
What is a nonpolar covalent bond?
This connective tissue type, found in the dermis of the skin, has collagen fibers arranged in multiple directions, allowing it to resist stress from many angles.
What is dense, irregular connective tissue?
