Carries deoxygenated blood from body organs to the right atrium.

Carries oxygenated blood from the left ventricle to body organs.

Carries deoxygenated blood away from the right ventricle to the lungs.

Carries oxygenated blood from the lungs to the left atrium.

Air in the pleural space.

Treatment for pneumothorax, removing fluid from pleural space.

ATP releases energy by breaking a phosphate bond, becoming ADP + P.

Cells in nervous tissue that are NOT neurons, supporting cells.

The process of moving messenger RNA (mRNA) from the nucleus to the ribosomes in the cytoplasm.

The bonds that link amino acids together in a protein chain.

The heart chamber that receives oxygenated blood from the lungs.

Inflammation of the urinary bladder, causing frequent and painful urination.

The sphincter controlling the release of chyme (partially digested food) from the stomach into the duodenum.

The process of adding hydrogen atoms to unsaturated fats, creating trans fats.

The breakdown of fatty acids into acetyl groups.

The part of the nephron where blood filtration happens.

Centrioles are cell organelles that play a critical role in cell division.

Mitochondria are the powerhouses of the cell, producing most of the cell's energy (ATP).

Lysosomes contain enzymes that break down waste and cellular debris.

Margarine is a common source of trans fats.

Oils are substances that participate in hydrophobic interactions.

Atelectasis is a partial or complete collapse of a lung or lung lobe.

The trachea contains rings of cartilage and the epiglottis is above the larynx, protecting the airway.

The pulmonary valve is the heart valve that serves as the exit from the right ventricle.

Cations are positively charged ions, while anions are negatively charged ions. These opposite charges attract each other.

The dorsal cavity encompasses the cranial cavity (containing the brain) and the vertebral cavity (containing the spinal cord).

The pericardial cavity is located within the thoracic cavity and surrounds the heart. It contains a fluid that lubricates the heart and reduces friction.

The abdominal cavity is the largest body cavity, located below the diaphragm & containing major organs like the stomach, liver, intestines, and kidneys.

The rate at which the body burns calories for energy. It represents the overall energy expenditure of the organism.

The pelvic cavity is located below the abdominal cavity. It contains the bladder, reproductive organs, and the lower part of the digestive system.

When a tissue or organ relies solely on glucose for energy and cannot utilize ketones, a type of alternative fuel.

The pleural cavities are located within the thoracic cavity, encompassing each lung. Each cavity contains fluid that lubricates the lungs and reduces friction.

A type of active transport that uses membrane proteins to move particles against their concentration gradient, requiring ATP for energy.

The liver is situated in the upper right quadrant of the abdomen.

The body can store a limited amount of glucose as glycogen, typically around 2 lbs.

The first electron orbit can hold a maximum of 2 electrons. The third electron orbit can hold a maximum of 8 electrons.

Thymine is a nucleic base found in DNA, but not in RNA.

Proteins have four levels of structure: primary, secondary, tertiary, and quaternary. Each level describes a specific arrangement of amino acids.

The liquid inside a cell, also known as intracellular fluid, is the environment where many cellular processes occur.

A weak bond that forms between molecules with partially positive and negative charges. It is NOT a type of covalent bond.

The pleural cavity houses the lungs. It's a space between the two layers of pleura, a membrane that surrounds the lungs.

The high energy bond in ATP is situated between the second and third phosphate groups. Breaking this bond releases energy, converting ATP into ADP.

The nucleolus is responsible for producing ribosomes, essential for protein synthesis. Ribosomes are like tiny factories that create proteins based on genetic instructions.

The endoplasmic reticulum (ER) is a network involved in protein synthesis, modification, and transport. There are two types: rough ER with ribosomes for protein synthesis and smooth ER for lipid production.

Ribosomes translate mRNA into a polypeptide chain, which ultimately forms proteins. They're like the translators of genetic instructions.

Centrioles are involved in cell division, they organize the microtubules that form spindle fibers during mitosis and meiosis.

The anaerobic respiration of one glucose molecule yields up to 2 ATP. It's less efficient than aerobic respiration, but it can provide energy when oxygen is limited.
